Recent action in the stock market has been a bit nostalgic for investors.  Not that it's good nostalgia.  Back in 2008 and early 2009, a 1% day was a regular occurrence.  Heck, 3% days were a regular occurrence.  But once things stabilized after the March lows, volatility returned to earth, and a 1% day in either direction became much less common.  Over the last 15 trading days, however, 9 of them have seen the S&P 500 move at least +/-1%.  As shown in the chart below, this is the highest level since last June.
