Volatility versus mean return
Volatility shows the fluctuation in periodic returns from average returns. This is known as the total risk in the portfolio. The mean return shows the average daily return of FEZ.
There are two types of total risk—systematic risk and non-systematic risk. Non-systematic risk can be minimized by diversification, whereas systematic risk cannot be diversified. Systematic risk is measured by its beta, and volatility measures both systematic and non-systematic risk.
In the period from October 1–30, 2015, Société Generale’s non-systematic risk rose. As a result, its total volatility rose to 9.8%, and its mean return was 0.3%. The non-systematic risk rose in the stock because of weak capital market revenue in 3Q15.
