Value at Risk is your digital assistant for quantitative risk assessment of equity portfolio on demand. Input: 1) expected return, 2) volatility, and 3) your confidence level in percent. Assuming the underlying distribution is a bell curve (normal distribution), Value at Risk estimates the potential downside of P99, P95, P90 or any desired confidence levels. By playing what-ifs and different scenarios, investors will develop a better feel for downside risk exposure, i.e., the "worst" percent portion of the bell curve. For reference on methods, see "An Introduction to Value at Risk (VaR)" at Investopedia.com.
