Periods of market volatility have peppered the past century. As many investors know, these ups and downs can wreak havoc on our portfolios and emotions. However, history has shown that in times of turmoil, sticking to a disciplined strategy can pay off.

Few investors could have predicted that a viral outbreak would end the longest-running bull market in U.S. history. Now, the COVID-19 pandemic has pushed stocks far into bear market territory. From its peak on February 19th, the S&P 500 has fallen almost 30%.

Financial markets have exhibited high levels of volatility over the past several weeks as they react to factors that include reduced interest rates, a steep decline in oil prices and the economic and business implications of the coronavirus (COVID-19) outbreak.
