Glossary: Exotic and Volatility Products

This glossary covers the essential vocabulary of exotic derivatives and volatility products. These instruments sit at the more complex end of financial markets, but understanding their terminology helps you make sense of structured product disclosures, market commentary during volatile periods, and the mechanics behind popular volatility-linked ETFs and ETNs. Terms are organized alphabetically, with practical context for when and where you might encounter each one.

TL;DR: This glossary covers 40+ essential terms related to exotic options, volatility products, and structured derivatives. Most retail investors will encounter these concepts through volatility ETFs/ETNs, structured notes sold by banks, or market commentary during periods of stress. Understanding the vocabulary helps you evaluate risk disclosures and avoid products you do not fully understand.

A

Accumulator An accumulator is a structured product that obligates the buyer to purchase a set quantity of an underlying asset at a fixed price on a series of dates, as long as the asset stays within a specified price range. If the asset price rises above an upper barrier (the "knock-out"), the contract terminates early, capping the buyer's gains. If the price falls below a lower barrier, the buyer may be forced to purchase at double the usual quantity. Accumulators are sometimes called "I kill you later" in trading circles because the downside exposure can escalate rapidly.

Why this matters: Accumulators are sold by private banks to high-net-worth clients. They can produce steady gains in calm markets but devastating losses in sharp downturns, as buyers are locked into purchasing a depreciating asset at above-market prices.

Asian Option An Asian option derives its payoff from the average price of the underlying asset over a specified period, rather than the price at a single point in time. This averaging mechanism reduces the impact of short-term price spikes or manipulation near expiration. Asian options are common in commodity markets, where producers and consumers want hedges that reflect their actual realized prices over weeks or months, not a single day's closing price.

Common in Practice: Frequently used in commodity hedging and some structured notes.

At-the-Money (ATM) An option is at-the-money when its strike price equals (or is very close to) the current market price of the underlying asset. ATM options have the highest time value and are the most sensitive to changes in implied volatility. When market commentary refers to "ATM vol," it means the implied volatility of options struck at the current market price, which serves as a baseline for measuring the overall cost of options protection.

Autocallable An autocallable is a structured note that automatically redeems (or "calls" itself) early if the underlying asset reaches a predetermined price level on one of several observation dates. If the product is called, the investor receives their principal plus a coupon. If the product is never called during its life and the underlying falls below a barrier at maturity, the investor can lose a significant portion of their principal. Autocallables are among the most widely sold structured products globally.

Why this matters: Autocallables are commonly marketed to retail investors seeking yield. The coupon payments can appear attractive, but the downside risk is concentrated in severe market declines, which is exactly when investors can least afford losses.

Common in Practice: Widely sold through banks and wealth management platforms.

---

B

Barrier Option A barrier option is an exotic option that either activates ("knocks in") or terminates ("knocks out") when the underlying asset's price crosses a specified barrier level. For example, a down-and-in put with a barrier at $80 on a stock trading at $100 only becomes a live put option if the stock drops to $80. Barrier options are cheaper than standard (vanilla) options because the barrier condition reduces the probability of a payout.

Example: You buy a knock-out call on Stock X with a strike of $50 and an upper barrier of $70. If the stock rises past $70 at any point, the option ceases to exist and you lose your premium, even though the stock moved in your favor. The barrier makes the option cheaper upfront but introduces the risk of it disappearing at an inconvenient time.

Why this matters: Barrier options appear in many structured products. When a bank offers "conditional protection" or "contingent participation," barrier options are often the underlying mechanism. Understanding barriers helps you evaluate what conditions could cause you to lose money.

Basket Option A basket option has a payoff that depends on the combined performance of multiple underlying assets, such as a group of stocks or indices. Rather than tracking a single stock, a basket option might reference the weighted average return of five tech stocks. Basket options are used in structured products to provide diversified exposure and typically cost less than buying individual options on each component, because the correlations between the assets reduce overall portfolio volatility.

Rainbow Option, Worst-Of Option

Bermuda Option A Bermuda option can be exercised on specific dates before expiration, not just at expiration (European style) and not on any day (American style). The exercise dates are typically monthly or quarterly. Bermuda options are common in interest rate markets and certain structured products, where the periodic exercise feature aligns with coupon payment dates or reset schedules.

Binary Option (also called Digital Option) A binary option pays a fixed amount if a specific condition is met at expiration (for example, the underlying is above the strike price) and nothing otherwise. There is no partial payout: it is all or nothing. Legitimate binary options exist in institutional markets, but the term has become associated with unregulated online platforms that have drawn enforcement actions from regulators worldwide.

Why this matters: Unregulated binary option platforms have been a significant source of retail investor fraud. If you encounter binary options outside of regulated exchanges, exercise extreme caution.

Common in Practice: Available on some regulated exchanges (e.g., Nadex in the US), but heavily associated with fraud on unregulated platforms.

C

Cliquet (also called Ratchet Option) A cliquet is a series of consecutive forward-start options, where the strike price resets at each observation date to the then-current market price. At each reset, any gains are "locked in," meaning they cannot be lost in subsequent periods. Cliquets are popular in equity-linked structured products and insurance-linked investments because they offer participation in upside moves while protecting previously accumulated gains. The trade-off is that participation rates are often capped at each reset period.

Example: A one-year cliquet with monthly resets on the S&P 500 might lock in gains each month up to a 2% cap. If the index rises 5% in January, you capture 2%. If it falls 3% in February, your floor prevents losing the January gain. At maturity, you receive the sum of capped monthly returns, subject to a minimum of 0%.

Common in Practice: Found in equity-indexed annuities and capital-protected structured notes.

Compound Option A compound option is an option on an option. The buyer pays a premium for the right to purchase (or sell) another option at a later date at a predetermined price. Compound options are used when there is uncertainty about whether a hedge will be needed, such as during a pending corporate transaction. They allow the buyer to defer the full cost of the hedge until more information is available.

Contango Contango describes a futures market condition where contracts with later expiration dates trade at higher prices than near-term contracts. In volatility products, contango in VIX futures means that the cost of future volatility protection is higher than the current spot VIX level. This price structure creates a persistent drag on long volatility ETFs and ETNs because they must regularly sell cheaper near-term contracts and buy more expensive longer-term ones.

Why this matters: Contango is the primary reason that buy-and-hold positions in long volatility ETFs (like VXX or UVXY) lose value over time, even if the VIX itself is unchanged. Understanding contango is essential before investing in any volatility product.

Common in Practice: Directly affects anyone holding VIX ETFs or ETNs.

Convexity In the context of volatility products, convexity refers to the non-linear relationship between an instrument's price and movements in its underlying variable. A product with positive convexity gains more from a favorable move than it loses from an unfavorable move of the same size. Tail-risk hedges and deep out-of-the-money options exhibit convexity, which is why they can produce outsized returns during market crashes relative to their cost.

D

Delta Hedging Delta hedging is the practice of offsetting the directional risk of an options position by trading the underlying asset. A market maker who sells a call option will buy shares of the underlying stock proportional to the option's delta to neutralize the position's sensitivity to small price changes. Delta hedging must be continuously adjusted as the underlying price moves, which generates transaction costs and can amplify market moves during periods of low liquidity.

Greeks, Gamma

Digital Option (also called Binary Option) A digital option pays a fixed, predetermined amount if the underlying asset satisfies a specific condition at expiration, and pays zero otherwise. The payoff is discontinuous: it jumps from zero to the fixed amount at the strike price. Digital options are embedded in many structured products as the mechanism that determines whether a coupon is paid or a barrier is breached.

Binary Option, Barrier Option

Down-and-In A down-and-in option is a type of barrier option that only becomes active if the underlying asset's price falls to or below a specified barrier level. Until the barrier is hit, the option does not exist for practical purposes. Once activated, it behaves like a standard option. Down-and-in puts are commonly embedded in structured products to provide conditional downside protection.

See also

Barrier Option, Knock-In

Down-and-Out A down-and-out option is a barrier option that ceases to exist if the underlying asset's price falls to or below a specified barrier level. The option is alive as long as the price stays above the barrier, but a single touch of the barrier terminates it permanently. This structure is used to create cheaper hedges for scenarios where the holder believes a large decline is unlikely.

E

Exotic Option An exotic option is any option contract with features that differ from standard (vanilla) European or American puts and calls. The "exotic" label covers a broad range of structures, including barrier options, Asian options, lookback options, binary options, and many others in this glossary. Exotic options are typically traded over-the-counter (OTC) between institutional counterparties, though some appear in structured products available to retail investors. They are generally more difficult to price, hedge, and understand than vanilla options.

Why this matters: When a structured product offers an unusual payoff profile, exotic options are almost certainly involved. The complexity makes it harder to assess fair value, which is why these products tend to carry wider margins for the issuing bank.

---

F

Forward Start Option A forward start option is an option whose strike price is not determined until a future date, at which point it is typically set at-the-money (equal to the underlying's price on that date). Forward start options are the building blocks of cliquets. They are useful when an investor wants options exposure starting at a future date without committing to a specific strike price now.

See also

Cliquet

Futures-Based Volatility Product A futures-based volatility product is an ETF, ETN, or fund that gains exposure to volatility by holding VIX futures contracts rather than directly tracking the VIX index itself. Because VIX futures and the spot VIX can behave very differently, especially over longer holding periods, these products often diverge significantly from the VIX index. The constant rolling of futures positions creates costs (in contango) or gains (in backwardation) that dominate long-term returns.

Why this matters: The most commonly traded volatility products (VXX, UVXY, SVXY) are all futures-based. None of them track the spot VIX directly. This distinction is the single most important concept for anyone considering a volatility product investment.

Common in Practice: VXX, UVXY, SVXY, and similar products.

G

Gamma Gamma measures how much an option's delta changes for a one-point move in the underlying asset's price. High gamma means the option's directional exposure is shifting rapidly, requiring more frequent delta hedging. Gamma is highest for at-the-money options near expiration, which is why options expiration days can see unusual market activity as dealers adjust their hedges.

Delta Hedging, Greeks

Greeks The Greeks are a set of risk measures that describe how an option's price changes in response to various factors: delta (underlying price), gamma (rate of delta change), theta (time decay), vega (implied volatility), and rho (interest rates). Traders use the Greeks to understand, quantify, and manage the multiple dimensions of risk in an options portfolio. In exotic options, additional Greeks (such as vanna and volga) become important because the payoff structures are more sensitive to complex interactions between variables.

Common in Practice: Any options trader or investor uses the Greeks, even if only implicitly through a brokerage platform's risk display.

H

Himalaya Option A Himalaya option is a multi-asset exotic option where, at each observation date, the best-performing asset in a basket is removed and its return is locked in. The process continues until all assets have been removed or the option expires. The final payoff is typically the average or sum of the locked-in returns. Himalaya options reward diversified baskets where different assets take turns outperforming, and they are occasionally found in structured notes marketed to high-net-worth investors.

Basket Option, Rainbow Option

K

Knock-In Knock-in is a barrier condition that activates an option when the underlying asset's price reaches a specified level. Before the barrier is touched, the option has no value and cannot be exercised. Knock-in options are cheaper than equivalent vanilla options because there is a chance the barrier is never reached and the option never comes into existence.

See also

Barrier Option, Down-and-In, Up-and-In

Knock-Out Knock-out is a barrier condition that terminates an option when the underlying asset's price reaches a specified level. Once the barrier is touched, the option ceases to exist, regardless of where the underlying price goes afterward. Knock-out options are also cheaper than vanilla equivalents, but carry the risk that a temporary price spike or dip permanently eliminates the position.

Barrier Option, Down-and-Out, Up-and-Out

---

L

Ladder Option A ladder option locks in gains as the underlying asset's price crosses predetermined price levels ("rungs"). Once a rung is reached, the minimum payout increases to the intrinsic value at that level, regardless of subsequent price movements. Ladder options are similar to cliquets in concept but use fixed price levels rather than periodic time-based resets. They appear in some capital-protected structured products.

See also

Cliquet

Lookback Option A lookback option allows the holder to "look back" over the life of the option and base the payoff on the most favorable price the underlying achieved during that period. A lookback call, for instance, uses the lowest price during the option's life as the effective strike, giving the holder the benefit of perfect market timing. This feature makes lookback options expensive relative to standard options, and they are found primarily in structured products rather than as standalone instruments.

---

M

Mean Reversion Mean reversion is the tendency of a variable to drift back toward its long-term average over time. Volatility is one of the most strongly mean-reverting variables in financial markets: periods of high volatility tend to be followed by declining volatility, and periods of low volatility tend to be followed by increases. This property is fundamental to volatility trading strategies, as it creates opportunities to sell volatility when it is elevated and buy it when it is depressed.

Why this matters: Mean reversion is the core assumption behind many volatility trading strategies, including short VIX positions. However, the timing and speed of mean reversion are unpredictable, and volatility can stay elevated (or depressed) for longer than expected, which is a frequent source of losses.

Common in Practice: Relevant to anyone trading volatility ETFs or options strategies.

---

P

Path-Dependent Option A path-dependent option has a payoff that depends not just on the final price of the underlying asset, but on the specific path the price took to get there. Barrier options, Asian options, and lookback options are all path-dependent. Two assets that start and end at the same price can produce very different payoffs on a path-dependent option if one moved smoothly while the other experienced large swings along the way.

See also

Asian Option, Barrier Option, Lookback Option

Payoff Diagram A payoff diagram is a graph that shows the profit or loss of an options strategy at expiration for each possible price of the underlying asset. The x-axis represents the underlying price, and the y-axis represents the strategy's profit or loss. Payoff diagrams are an essential tool for understanding any options position because they make the risk-reward profile visual and concrete. For exotic options, payoff diagrams can be more complex, sometimes showing conditional payoffs that depend on barrier levels or averages.

Common in Practice: Every options education resource and most brokerage platforms use payoff diagrams.

---

Q

Quanto Option A quanto option is a derivative denominated in a currency different from the underlying asset's natural currency, with a fixed exchange rate built into the contract. For example, a quanto option on the Nikkei 225 might pay out in US dollars using a predetermined USD/JPY rate, eliminating currency risk for the investor. Quantos are common in cross-border structured products and global equity-linked notes.

---

R

Rainbow Option A rainbow option is an exotic option whose payoff depends on the relative performance of two or more underlying assets. The simplest example is a "best-of" option that pays the return of whichever asset in a basket performed best. Rainbow options can also be structured as "worst-of" (paying the worst performer's return), "spread" (paying the difference between two assets), or other configurations. They are frequently embedded in structured notes.

Basket Option, Himalaya Option, Worst-Of Option

Realized Volatility (also called Historical Volatility) Realized volatility measures the actual price fluctuations of an asset over a past time period, calculated as the annualized standard deviation of returns. It is backward-looking, unlike implied volatility, which is forward-looking. The difference between implied and realized volatility (the "volatility risk premium") is a key concept in volatility trading: implied volatility tends to be higher than subsequent realized volatility on average, which is why systematically selling options has historically been profitable, though with significant tail risk.

Common in Practice: Reported on financial data platforms and used in options analysis.

VIX, Volatility Skew

Roll Yield Roll yield is the gain or loss generated when a futures position is "rolled" from an expiring contract to a later-dated one. In a contango market (where later contracts cost more), rolling produces a negative roll yield, which erodes the value of long positions. In backwardation (where later contracts cost less), rolling produces a positive roll yield. For VIX-based products, roll yield is the dominant driver of long-term returns and is typically negative, creating a persistent headwind for long volatility ETFs.

Why this matters: Negative roll yield is the reason products like VXX lose the vast majority of their value over time. A buy-and-hold approach to long volatility ETFs is almost certain to lose money because of this effect. Understanding roll yield is essential before trading any futures-based volatility product.

Common in Practice: Directly relevant to VXX, UVXY, SVXY, and all VIX ETFs/ETNs.

S

Straddle A straddle is an options strategy that involves buying (or selling) both a call and a put at the same strike price and expiration. A long straddle profits from large price moves in either direction, while a short straddle profits from the underlying staying near the strike price. Straddles are a direct way to express a view on volatility: buying a straddle is a bet that realized volatility will exceed what is implied by current option prices.

Common in Practice: Widely used by retail and institutional traders around earnings announcements and other events.

See also

Strangle

Strangle A strangle is similar to a straddle but uses different strike prices for the call and the put, typically placing both out-of-the-money. A long strangle is cheaper than a long straddle because the options are further from the current price, but it requires a larger price move to become profitable. Short strangles are a common income strategy but carry significant risk if the underlying makes a large move in either direction.

Common in Practice: One of the most traded volatility strategies for both retail and institutional participants.

Straddle

Structured Note A structured note is a debt security issued by a bank that combines a bond component with one or more derivative components to create a customized payoff profile. The derivative component often involves exotic options such as barriers, autocall features, or basket references. Structured notes can offer payoffs not available through standard instruments, but their complexity makes it difficult for investors to assess fair value, and the investor bears the credit risk of the issuing bank.

Why this matters: Structured notes are among the most commonly sold complex products to retail investors. The embedded fees are not always transparent, and the issuing bank's profit margin can be substantial. Always compare the note's expected return to simpler alternatives before investing.

Common in Practice: Sold through brokerages, wealth management platforms, and private banks worldwide.

Autocallable, Barrier Option

Swap A swap is a derivative contract in which two parties exchange cash flows based on different underlying variables. In volatility markets, the most common types are variance swaps and volatility swaps, which allow parties to trade the difference between implied and realized volatility. Swaps are over-the-counter instruments traded between institutional counterparties, though their effects reach retail investors through the products and strategies built on top of them.

T

Term Structure Term structure refers to the relationship between the prices (or implied volatility levels) of contracts with different expiration dates. The VIX futures term structure shows how the market prices volatility expectations at different horizons: one month, two months, three months, and so on. A steep term structure (with longer-dated contracts much more expensive) amplifies the negative roll yield for long volatility products, while a flat or inverted structure reduces it.

Common in Practice: VIX term structure charts are widely available and are an essential tool for volatility product investors.

Contango, Roll Yield

Theta Decay (also called Time Decay) Theta measures the rate at which an option loses value as time passes, all else being equal. Options are wasting assets: their time value decreases every day, and this decay accelerates as expiration approaches. Theta decay is the mechanism by which options sellers generate income and options buyers face a persistent headwind. In volatility products, theta decay interacts with roll yield to create the characteristic value erosion in leveraged and long volatility ETFs.

Common in Practice: Relevant to every options position and every volatility product.

U

Up-and-In An up-and-in option is a barrier option that only becomes active if the underlying asset's price rises to or above a specified barrier level. These options are used to structure payoffs that only participate in upside moves beyond a certain threshold, and they are cheaper than equivalent vanilla options because activation is not guaranteed.

See also

Barrier Option, Knock-In

Up-and-Out An up-and-out option is a barrier option that terminates if the underlying asset's price rises to or above a specified barrier level. Up-and-out calls are sometimes called "capped calls" because they cap the holder's gains if the underlying rallies too strongly. They are embedded in some structured products to reduce costs, with the trade-off being that large upside moves eliminate the position.

Barrier Option, Knock-Out

---

V

Variance Swap A variance swap is a derivative contract that pays the difference between realized variance (the square of realized volatility) and a predetermined strike variance. Unlike a volatility swap, the variance swap's payoff is linear in variance, which means it has convex exposure to volatility: large moves in realized volatility produce disproportionately large payoffs. Variance swaps are institutional instruments, but they are significant because the VIX index itself is calculated using a methodology closely related to variance swap pricing.

Realized Volatility, VIX, Swap

Vega Vega measures how much an option's price changes for a one-percentage-point change in implied volatility. Options with high vega are more sensitive to shifts in market expectations about future volatility. Long vega positions (such as long options or long volatility products) profit when implied volatility rises, while short vega positions profit when implied volatility falls. Vega is largest for at-the-money options with longer time to expiration.

Greeks, Implied Volatility, Volatility Surface

VIX (CBOE Volatility Index) The VIX is a real-time index that represents the market's expectation of 30-day forward-looking volatility on the S&P 500, derived from the prices of S&P 500 index options. It is often called the "fear gauge," though it more accurately reflects the cost of options protection. The VIX is not directly investable. You cannot buy or sell the VIX itself. All VIX-linked investment products use VIX futures, which behave differently from the spot VIX index.

Why this matters: The VIX is the most widely referenced volatility measure in financial markets. However, the critical distinction between the VIX index and VIX futures is the source of most confusion and losses for retail volatility traders. The products you can actually trade (VXX, UVXY, etc.) track VIX futures, not the VIX itself.

Common in Practice: Referenced in virtually all market commentary and the basis for a large ecosystem of tradable products.

VIX Futures, Futures-Based Volatility Product, VVIX

VIX Futures VIX futures are standardized contracts that represent the market's expectation of the VIX level at a specific future date. They are listed on the Cboe Futures Exchange with monthly and weekly expirations. VIX futures converge to the spot VIX at expiration but can trade at significantly different levels before that. The spread between VIX futures prices and the spot VIX, along with the shape of the futures term structure, drives the roll yield that dominates long-term returns of volatility ETFs and ETNs.

Common in Practice: The underlying instruments for all VIX ETFs and ETNs.

Volatility Skew Volatility skew describes the pattern where options at different strike prices on the same underlying and expiration have different implied volatilities. In equity markets, puts (especially out-of-the-money puts) typically have higher implied volatility than calls, creating a downward-sloping skew. This reflects greater demand for downside protection and the market's recognition that large downward moves are more likely than standard models suggest. Skew steepness is itself a tradable variable and a useful indicator of market sentiment.

See also

Volatility Smile, Volatility Surface

Volatility Smile The volatility smile is a U-shaped pattern where both deep out-of-the-money puts and deep out-of-the-money calls have higher implied volatility than at-the-money options. This pattern is most pronounced in currency markets and some commodity markets. The smile contradicts the Black-Scholes model's assumption of constant volatility and reflects the market's expectation of large moves in either direction. In equity markets, the pattern is usually asymmetric (steeper on the put side), which is why it is more commonly called a "skew."

See also

Volatility Skew, Volatility Surface

Volatility Surface The volatility surface is a three-dimensional representation of implied volatility across both strike prices and expiration dates. It combines the information from the volatility skew (across strikes) and the term structure (across time) into a single visualization. The volatility surface is the primary tool that options traders and risk managers use to understand the full landscape of how the market prices options risk. Changes in the shape of the surface carry information about shifting market expectations and risk sentiment.

Volatility Skew, Term Structure

VVIX (Volatility of Volatility Index) The VVIX measures the expected volatility of the VIX itself, calculated from VIX option prices in the same way the VIX is calculated from S&P 500 option prices. A high VVIX indicates that the market expects large swings in the VIX, which typically coincides with periods of market stress or uncertainty. The VVIX can be useful as a second-order fear gauge: it tells you not just whether volatility is high, but whether volatility itself is expected to be volatile.

W

Worst-Of Option A worst-of option is a multi-asset option whose payoff is determined by the worst-performing asset in a basket. If three stocks are referenced and one falls 30% while the others rise, the payoff is based on the 30% decline. Worst-of options are the most common type of multi-asset exotic option in retail structured products because they are cheap to buy (from the issuer's perspective), which allows the issuer to offer higher coupons. The trade-off is that the investor bears the concentrated risk of the single worst performer.

Why this matters: Many high-coupon structured notes use worst-of mechanics. The attractive yield compensates for the risk that you are effectively selling insurance on whichever asset in the basket performs worst. During market stress, correlations between assets often increase, which means the "diversification benefit" of a basket can disappear precisely when you need it most.

Common in Practice: One of the most common structures in retail autocallable and barrier reverse convertible notes.

Key Relationships

Understanding how these terms connect helps build a coherent mental model of the exotic and volatility product landscape.

The Barrier Option Family Barrier options are the foundation of many structured products. They come in four standard types based on direction and activation: down-and-in, down-and-out, up-and-in, and up-and-out. Knock-in and knock-out are the general terms for the activation and deactivation mechanisms. Many autocallables and structured notes embed barrier options to create conditional payoffs.

The Volatility Product Chain The VIX index is derived from S&P 500 option prices. VIX futures are contracts that bet on where the VIX will be in the future. Futures-based volatility products (ETFs and ETNs) hold VIX futures. The term structure of VIX futures determines contango or backwardation. Roll yield is the cost or benefit of maintaining futures positions over time. Together, these concepts explain why long volatility products lose value in calm markets and spike during crises.

Multi-Asset Exotic Options Basket options are the broad category. Rainbow options pay based on relative performance (best-of, worst-of, spread). Himalaya options sequentially remove best performers. Worst-of options, the most common in practice, pay based on the weakest asset. These structures appear in structured notes and autocallables, where they allow issuers to offer higher coupons in exchange for concentrated risk.

Path Dependency Spectrum Vanilla options depend only on the final price. Asian options depend on the average path. Barrier options depend on whether the path crossed a specific level. Lookback options depend on the extreme points of the path. Cliquets depend on performance at discrete intervals along the path. More path dependency generally means more complexity and wider pricing margins.

Volatility Surface Components Implied volatility varies across strike prices (skew/smile) and across expiration dates (term structure). The combined surface is the volatility surface. Vega measures sensitivity to the surface level. The Greeks collectively describe how an option position responds to changes in the surface and other factors.
