Similar calculations can be made for daily volatilities based on the number of trading days in the year, typically assumed to be 252days. VIX does that by looking at put and call option prices within the S&P 500, a benchmark index often used to represent the market at large.

We recommend that you seek independent advice and ensure you fully understand the risks involved before trading. Volatility is often measured using standard deviation, or by looking at the variation between the asset’s price movements and the movements of its underlying index. Volatile markets are characterized by extremely fast-paced price changes and high trading volume, which is seen as increasing the likelihood that the market will make major, unforeseen price movements. On the other hand, markets that exhibit lower volatility tend to remain stable, and have less-dramatic price fluctuations.

Finally, we know that the standard deviation is the square root of variance, so we can replace the √σ2 with σ. For each increment of a price’s random walk, the variance is proportional to the time taken. It is also not a constant; every stock has some periods of high volatility and other periods with comparatively low. There may be more or less variation, but it is never a constant, although for some economic applications it is assumed to be.
