Risk by Underlying Report

The Risk by Underlying report is designed to open by default when you open the IB Risk NavigatorSM. This report displays portfolio metrics across all asset classes and provides drill-down depth control for each underlying.

The table below shows all available metrics and measures for the Risk by Underlying report.

Metrics	Description
Position	Your (signed) position in the contract. A short position is indicated by the "-" (minus) sign.
Price	The current market price of one unit of the contract.
Value	The (price) x (position).
P&L	The "unrealized" Average Cost P&L is shown in total, per underlying, and for each position.
Exposure	The exposure is calculated using the formula: position x delta x multiplier x underlying price. NOTE: The exposure for each asset class is converted to a share-equivalent value for easy comparisons between classes.
VAR	Value at Risk (VAR) is a measure of market exposure. It shows the greatest expected loss over a one-day period, with 99.5% confidence. NOTE: In cases where the VAR cannot be calculated, the notation "N/A" is displayed on a violet background.
Delta	Delta captures both the direction and the magnitude of the portfolio's sensitivity to an underlier by representing the degree and direction of change in the option price, based on a change in the price of the underlier. We use a capital "D" to differentiate the IB Risk Navigator "position Delta" calculated as (delta * position) from the greek delta calculation.
Gamma	Gamma helps you assess directional risk by defining the speed at which the option's directional changes will occur, i.e. the rate of change of delta. We use a capital "G" to differentiate the IB Risk Navigator "position Gamma" calculated as (gamma * position) from the greek gamma calculation.
Vega	Vega represents the portfolio's sensitivity to changes in implied volatility of the underliers, and reflects the change in the price of an option relative to a change in the implied volatility of the underlier. Generally long option positions benefit from rising (and suffer from declining) implied volatilities, while short option positions experience the opposite - they benefit from declining (and suffer from rising) implied volatilities. We use a capital "V" to differentiate the IB Risk Navigator "position Vega" calculated as (vega * position) from the greek vega calculation.
Theta	Theta represents the portfolio's sensitivity to the passage of time by indicating the rate at which the market value of your portfolio will change with time. This metric calculation is based on the assumption that all other variables remain unchanged, including the underlying price, implied volatility and interest rate. We use a capital "T" to differentiate the IB Risk Navigator "position Theta" calculated as (theta * position) from the greek theta calculation.
