FYI: There is no doubt that 2018 has been plagued by market volatility; however, this sentiment is accentuated by recency bias. Last year left investors with a false sense of security, and the extremely low volatility we saw in 2017 made market participants forget that the stock market has historically been riddled with volatility and corrections.
As we begin the second quarter of 2018, market volatility seems to be sticking around. For the second time in a week and just the second time since the 2016 presidential election, last week the S&P 500 closed below its 200-day moving average, a key technical indicator.
