The square root of the variance is then calculated, which results in a standard deviation measure of approximately 1.915. Or consider shares of Apple (AAPL) for the last five years. Returns for Apple’s stock were 37.7% for 2014, -4.6% for 2015, 10% for 2016, 46.1% for 2017 and -6.8% for 2018.

For example, in a stock with a mean price of $45 and a standard deviation of $5, it can be assumed with 95% certainty the next closing price remains between $35 and $55. However, price plummets or spikes outside of this range 5% of the time. A stock with high volatility generally has a high standard deviation, Interpret the standard deviation. As we can see that standard deviation is equal to 9.185% which is less than the 10% and 15% of the securities, it is because of the correlation factor: If correlation equals 1, standard deviation would have been 11.25%. If correlation equals 0, standard deviation would have been 8.38%.
