BSIG Market Implied Price Change vs. Actual Price Change

Option traders can use implied volatility from the option markets to develop an estimate for the expected price range of a stock over a period of time. We use the closest expiring options to develop a one-day expected price move (up or down) each day, and then compare those numbers to the actual price moves that occur. Below is a chart for the last 20 days, if available.
