It provides a broad chart to the analysts. The VaR at a probability level \ (p\) (e.g. 95%) is the \ (p\)-quantile of the negative returns, or equivalently, is the negative value of the \ (c=1-p\) quantile of the returns. In a set of returns for which sufficently long history exists, the per-period Value at Risk is simply the quantile of the period negative returns : $$VaR=q_ {.99}$$ Value At Risk (VaR) is one of the most important market risk measures.
