Knowing and understanding volatility is particularly important for range questions about min and max prices. If there is no major news, an asset will move within its average volatility. So there is no point in selecting extreme values if you don’t expect any important events. If an asset moves ±1% a day, then it’s unlikely that it will move ±3% over the next few days — such moves are relatively rare. If we have 30-day volatility of 5% , then on 20 of those days (i.e. 68%) the next day’s price should differ by less than 5% .
A company with a higher beta has greater risk and also greater expected returns. If beta is like a volume control, residual volatility is like changing the station. Instead of measuring how similarly an investment swings with an index, residual volatility measures how much of its price change comes in a way that is different from the index.

On the other hand, a beta of less than one implies a stock that is less reactive to overall market moves. And, finally, a negative beta tells investors that a stock tends to move in the opposite direction from the S&P 500.
