Parametric VaR = Portfolio Value x Z-score for the confidence level x Standard Deviation of Returns over the period Value Stock Market Basics & Instruments qualitative A share trading at a low price relative to accounting measures such as earnings, book value or cash flow. Test: low P/E, low P/B or high earnings yield relative to the market and to the company's own history Value Trap Fundamental Analysis & Valuation qualitative A share that looks cheap on backward-looking multiples but is cheap because its business is deteriorating.

Variance = Sum of (Return - Mean Return) squared / Number of Observations Vega Derivatives, Futures & Options The change in an option's price for a one-percentage-point change in implied volatility.
