_aioseop_keywords: S&P500, Volatility, 401k
I created a chart of the S&P500 daily % changes, squared them, and put them into an Excel chart. An interesting perspective was charted relative to the daily volatility and its spikes over the past 14 years. Most notable is that little spike we had on February 27, 2007. Something tells me that was a very significant day.
