Should You Worry About a Market Correction?
A 10% market correction occurs about once a year.
Sharp market drops can unnerve even the most seasoned investors, but a look back over the past 40 years shows that declines are a relatively routine occurrence. A market correction of 10% or more has occurred about once a year.
Bearish headlines, troubling events and disappointing economic news can fuel uncertainty. Rather than panicking when declines occur, focus on your long-term investment goals and avoid making quick decisions. Maintaining a diversified portfolio can help reduce the effects of volatility.

While there have been significant setbacks in each of the last 40 calendar years, the S&P 500 recorded a positive return in 30 of those years, or 75% of the time. However, it is important to remember that past results are not predictive of results in future periods.
Investors with the fortitude to ride out tough market conditions have often been rewarded. In contrast, investors who sold near the bottom of a decline often missed some of the market’s best days while sitting on the sidelines, as turnarounds often happen suddenly and can be significant.
