Why Volatility Also Matters

Diversification of assets is an prudent way to reduce risk in a portfolio. While the concept of diversification is important volatility is another factor that investors should focus on to generate higher returns.

Why does volatility matter?

The table shows the performance of two sample portfolios with both having an initial investment of $1.0 million:


Both the portfolios have an average return of 0% in two years. However Portfolio 1’s value at the end of 2nd year is only $750,000 while Portfolio 2 lost only $10,000 and has a value of $990,000. The reason for the difference in performance is that Portfolio 1 is much more volatile. Portfolio 2’s lower volatility produces a higher compounded return.

So the key takeaway from this post is that if two portfolios have the same average return then the portfolio with the lower volatility will always have the higher end value.
