Value-at-Risk (VaR) Features

VaR is a statistical measure used to assess the level of financial risk within a firm or portfolio over a specific time frame.
It provides a quantifiable figure representing potential losses in normal market conditions, defined at a certain confidence level (e.g., 95% or 99%).

Downside/Quantile Risk Metric Focus

Downside risk metrics, like VaR, focus on potential losses rather than overall volatility or upside risks.
They measure the probability of extreme adverse price movements and are particularly important for risk-averse investors.

Definition of α-Quantile

The α-quantile of a continuous random variable X is the value below which a given percentage α of observations fall.
It effectively separates the lowest α proportion of the data from the remainder.

Range of α for α-Quantile

The range of α for calculating the α-quantile is between 0 and 1 (0 ≤ α ≤ 1).
An α of 0.5 would represent the median, while α values closer to 0 represent lower quantiles and those closer to 1 represent higher quantiles.

VaR and Risk Factor Sensitivities

VaR measures the risk factor sensitivities by evaluating how a portfolio's value could decline based on changes in market risk factors.
It encompasses various risk components, including market risk, credit risk, and operational risk, providing a holistic view of potential financial exposure.
