A) What is Kiyo Exposure?
The term "Kiyo Exposure" or "Kiyo Gamma Exposure" often refers to a metric, primarily Gamma Exposure (GEX), that quantifies the sensitivity of options portfolios to changes in the underlying asset's price. It's a critical concept, particularly for understanding market dynamics driven by options activity, often popularized by market commentators and data providers like Kiyo Capital.
At its core, Gamma Exposure measures how much the delta of an options position changes for every 1-point move in the underlying asset's price. When aggregated across many options positions (especially those held by market makers or large institutions), GEX can indicate whether options dealers will be forced to buy or sell the underlying asset as its price moves, thus potentially dampening or exacerbating price trends.
Who Should Use the Kiyo Exposure Calculator?
- Options Traders: To understand their personal portfolio's sensitivity to price changes and manage risk.
- Market Analysts: To gain insight into potential market-wide options flows and their impact on volatility.
- Risk Managers: To assess and hedge gamma risk within larger portfolios.
- Beginners: To learn how changes in underlying price, delta, and gamma affect their overall exposure.
Common Misunderstandings (Including Unit Confusion)
A common misunderstanding is confusing "Kiyo Exposure" with simply holding the underlying asset. While related through delta, Kiyo Exposure (GEX) specifically measures the *rate of change* of your delta, indicating how quickly your position becomes more or less bullish/bearish as the underlying moves. Unit confusion often arises between GEX expressed in shares (how many shares dealers might need to buy/sell) versus GEX expressed as a notional dollar value.
This Kiyo Exposure Calculator focuses on both shares equivalent and notional values to provide a comprehensive view, allowing users to select the most relevant interpretation for their analysis.
B) Kiyo Exposure Formula and Explanation
For an individual options position or portfolio, Kiyo Exposure (specifically Gamma and Delta Exposure) can be calculated using the following formulas. These formulas help translate the Greeks (Delta and Gamma) into tangible exposure values, either in terms of shares of the underlying asset or a notional dollar value.
Core Formulas:
- Total Shares Equivalent from Options:
Total Shares Equivalent = Number of Contracts × Shares per ContractThis calculates the total number of underlying shares that your option contracts represent.
- Total Delta Exposure (DEX) in Shares:
Total DEX (Shares) = Average Delta per Share × Total Shares EquivalentThis represents the equivalent number of underlying shares you are effectively long or short, based on your options' delta. A positive value means your position behaves like owning shares, a negative value like shorting shares.
- Total Gamma Exposure (GEX) in Shares:
Total GEX (Shares) = Average Gamma per Share × Total Shares EquivalentThis is the primary Kiyo Exposure metric, indicating how much your Total Delta (Shares) will change for every 1-point move in the underlying asset's price. A positive GEX means your delta becomes more positive as the price rises, and more negative as it falls.
- Delta Notional Value (DNV):
DNV = Total DEX (Shares) × Underlying Asset PriceThis converts your Delta Exposure into a dollar value, representing the approximate change in your position's value for a small 1-point move in the underlying asset.
- Gamma Notional Value (GNV):
GNV = Total GEX (Shares) × Underlying Asset PriceThis converts your Gamma Exposure into a dollar value, representing the approximate change in your Delta Notional Value for a small 1-point move in the underlying asset.
Variables Table:
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| Underlying Asset Price | Current market price of the asset (stock, ETF, etc.) | Currency (e.g., USD) | Positive, varies widely |
| Number of Option Contracts | The quantity of option contracts in your position | Count (unitless) | 1 to thousands |
| Shares per Contract | Number of underlying shares one option contract represents | Count (unitless) | 100 (for equity options), 10, 1 |
| Average Delta per Share | The sensitivity of your option's price to a $1 change in the underlying, per share | Unitless ratio | -1.00 to 1.00 |
| Average Gamma per Share | The rate at which your option's delta changes for a $1 change in the underlying, per share | Unitless ratio | Typically positive, small (e.g., 0.001 to 0.5) |
Understanding these variables and their impact on options pricing is crucial for effective risk management.
C) Practical Examples
Let's walk through a couple of examples to illustrate how the Kiyo Exposure Calculator works and how to interpret its results.
Example 1: Long Call Position
Imagine you hold a long position in call options on XYZ stock:
- Inputs:
- Underlying Asset Price: $120.00
- Number of Option Contracts: 5
- Shares per Contract: 100
- Average Delta per Share: 0.65
- Average Gamma per Share: 0.04
- Calculations:
- Total Shares Equivalent = 5 contracts * 100 shares/contract = 500 shares
- Total DEX (Shares) = 0.65 * 500 = 325 shares
- Total GEX (Shares) = 0.04 * 500 = 20 shares
- Delta Notional Value = 325 shares * $120/share = $39,000
- Gamma Notional Value = 20 shares * $120/share = $2,400
- Interpretation:
Your position behaves like owning 325 shares of XYZ stock in terms of immediate price sensitivity (Delta Exposure). More importantly, for every $1 increase in XYZ's price, your position's delta will increase by 20 shares (meaning you'll become effectively "longer" by 20 more shares). This positive Gamma Exposure indicates that your position will profit more from price movements in your favor (upwards) as they accelerate, and lose less from adverse movements, making it a "long gamma" position.
Example 2: Short Put Position (Bearish Gamma)
Consider a short put position on ABC stock:
- Inputs:
- Underlying Asset Price: $85.00
- Number of Option Contracts: -2 (representing a short position)
- Shares per Contract: 100
- Average Delta per Share: -0.30
- Average Gamma per Share: 0.06 (Gamma is always positive for a single option)
- Calculations:
- Total Shares Equivalent = -2 contracts * 100 shares/contract = -200 shares
- Total DEX (Shares) = -0.30 * -200 = 60 shares (Note: Short a put is long delta here)
- Total GEX (Shares) = 0.06 * -200 = -12 shares (Negative Gamma Exposure for short options)
- Delta Notional Value = 60 shares * $85/share = $5,100
- Gamma Notional Value = -12 shares * $85/share = -$1,020
- Interpretation:
Despite being short puts, your delta here is positive (60 shares equivalent), meaning you benefit from a rising underlying price. However, your Gamma Exposure is negative (-12 shares). This means for every $1 move in ABC's price, your delta will change by -12 shares. If ABC goes up, your delta will decrease (become less positive), meaning you become less bullish. If ABC goes down, your delta will increase (become more positive), meaning you become more bullish as the price falls. This "short gamma" position means you generally lose from large price movements in either direction and profit from the underlying staying stable. This is a common characteristic of options trading strategies that involve selling options.
D) How to Use This Kiyo Exposure Calculator
This calculator is designed for ease of use. Follow these simple steps to determine your Kiyo Exposure:
- Enter Underlying Asset Price: Input the current market price of the stock, index, or other asset your options are based on.
- Enter Number of Option Contracts Held: Input the total quantity of option contracts you have in the position you wish to analyze. For short positions, enter a negative number (e.g., -5 for 5 short contracts).
- Enter Shares per Contract: This is typically 100 for standard equity options. Adjust if you are dealing with mini-options or other contract specifications.
- Enter Average Delta per Share: Input the average delta of your option contracts, expressed per share of the underlying. This value can be obtained from your broker's platform or an options analysis tool. Remember, calls have positive delta (0 to 1), and puts have negative delta (-1 to 0).
- Enter Average Gamma per Share: Input the average gamma of your option contracts, also per share. Gamma is typically a positive value for individual options.
- Click "Calculate Exposure": The calculator will instantly display your Total Gamma Exposure (GEX) in Shares (highlighted), along with other key metrics like Delta Exposure and their notional dollar values.
- Interpret Results:
- Positive GEX (Shares): You are "long gamma," meaning your position benefits from increased volatility (large price movements) and your delta increases as the price moves in your favor.
- Negative GEX (Shares): You are "short gamma," meaning your position benefits from decreased volatility (price stability) and your delta moves against you as the price moves. This can lead to significant options risk management challenges.
- Use the "Reset" Button: To clear all inputs and start a new calculation with default values.
- "Copy Results" Button: Easily copy all calculated exposure metrics to your clipboard for record-keeping or sharing.
Remember, accurate input of Delta and Gamma is crucial for precise results. These values change dynamically with time, volatility, and underlying price.
E) Key Factors That Affect Kiyo Exposure
The Kiyo Exposure (primarily Gamma Exposure) of an options portfolio is highly dynamic and influenced by several key factors. Understanding these helps in managing risk and anticipating market movements.
- Underlying Asset Price:
As the underlying price moves, options move in and out-of-the-money, causing their individual deltas and gammas to change. Gamma tends to be highest for at-the-money (ATM) options and decreases as options move deep in-the-money (ITM) or out-of-the-money (OTM). Therefore, a portfolio's total GEX will fluctuate significantly with price changes.
- Implied Volatility:
Implied volatility (IV) is a critical determinant of option prices and, consequently, their Greeks. Higher IV generally leads to higher option prices and often higher gamma (especially for ATM options). A surge or drop in implied volatility can drastically alter the GEX of an entire market or individual portfolio.
- Time to Expiration:
Options closer to expiration tend to have higher gamma, especially when they are at-the-money. This is because their delta changes very rapidly with small price movements as expiration approaches. Farther dated options have lower gamma. As time passes (time decay), gamma for ATM options can increase significantly, while for ITM/OTM options it might decrease.
- Strike Price:
The strike price relative to the underlying price determines whether an option is ITM, ATM, or OTM. As mentioned, ATM options generally exhibit the highest gamma. A portfolio with many options clustered around the current underlying price will likely have higher GEX than one with options far OTM or ITM.
- Number of Contracts and Position Size:
This is a direct scaling factor. More contracts (or a larger position size in terms of shares represented) will directly result in higher absolute Gamma and Delta Exposure, assuming other factors remain constant. A small change in underlying price can have a much larger impact on a portfolio with high GEX.
- Option Type (Call vs. Put) and Position Direction (Long vs. Short):
While individual call and put options always have positive gamma, the *net* gamma of a portfolio depends on whether you are long or short these options. Long options (buying calls or puts) result in positive portfolio gamma, benefiting from volatility. Short options (selling calls or puts) result in negative portfolio gamma, benefiting from stability. The blend of long/short positions across calls and puts creates the overall market maker dynamics.
F) Frequently Asked Questions (FAQ) about Kiyo Exposure
A: Gamma Exposure (GEX) in "Shares" tells you how many equivalent underlying shares your delta will change by for every $1 move in the underlying asset. "Notional Value" (GEX Notional) converts this share amount into a dollar value by multiplying it by the underlying asset's price, giving you a monetary sense of this delta change.
A: GEX helps traders understand their portfolio's sensitivity to price acceleration. Positive GEX means your position gains momentum (delta increases) as the price moves in your favor, and loses less as it moves against you. Negative GEX means your delta works against you, making profits harder to achieve with large moves and potentially exacerbating losses. It's key for options risk management.
A: Yes, if you are primarily a seller of options (short calls or short puts), your portfolio will likely have negative Gamma Exposure. This means you profit when the underlying asset's price remains stable, but you face increasing risk (your delta moves against you) if the price makes a large move in either direction.
A: The accuracy of the calculator's output directly depends on the accuracy of the Delta and Gamma inputs you provide. These values are dynamic and change constantly with underlying price, time, and implied volatility. Always use the most current delta and gamma figures available from your broker or an options analysis platform for the best results.
A: No, this calculator does not calculate Delta and Gamma using models like Black-Scholes. Instead, it assumes you provide the Delta and Gamma values as inputs, which are typically derived from such models or market data. It then uses these inputs to calculate your overall exposure.
A: Delta per share ranges from -1.00 to 1.00. Call options have positive delta (0 to 1), and put options have negative delta (-1 to 0). Gamma per share is typically a positive, relatively small value (e.g., 0.001 to 0.5) for individual options, representing the rate of change of delta.
A: The chart illustrates how your *total* GEX in shares would change if the underlying price moved, assuming your *average gamma per share* remains relatively constant over a small price range. In reality, gamma itself changes with price. The chart provides a simplified visual aid for understanding sensitivity.
A: This calculator is designed for individual portfolio or position analysis. Market-wide Kiyo Exposure (often referred to as GEX for an entire index or stock) requires aggregating delta and gamma across all outstanding options, which is a much more complex calculation typically performed by specialized data providers.
