A portfolio that includes a good mix of stocks, bonds and other investments can help protect your portfolio if one area is not doing well. Unfortunately, when a global crisis strikes – like the Great Depression, the bursting of the Dot-Com bubble or the 2008 global financial crisis – investors tend to buy and sell everything based on the "global news."

When investments move in relation to each other, it’s called correlation. Assets with different characteristics – like stocks and bonds – tend to exhibit low correlations to each other in normal markets. That means that if the stock market is doing poorly one day, the bond market isn’t necessarily in the same rut.

During times of market stress, however, all assets tend to move in sync because they are all seen as more risky. The benefits of diversification can be eroded when correlations rise, as all assets begin to move similarly rather than separately.

ETFs and Correlations

Some have mistakenly associated ETFs with rising correlations. While ETF trading volume can spike when markets are in upheaval this is because investors are increasingly using ETFs to express market sentiment changes not because ETFs drive the market.

Though ETF trading volume tends to increase during uncertainty, ETFs are not the cause of increased correlations.
