As our Weak Close Indicator shows below, the number of weak market closes for the S&P 500 (red line, left axis, inverted) has shot up over the last three weeks or so and is now at a level not seen since the end of 2012. We note that a similar event happened in 2013-2014 and the market kept on advancing, but the move in the indicator over the last few weeks has been noteworthy.
