"About 90% of Russell 2000 stocks have already fallen into a correction. The S&P 500 has gone 34 days without rising 1% in any of them, the longest in 20 months. More than half the index’s members have suffered peak-to-trough declines of at least 10% since May. "

Since 1950, the S&P 500 has registered a 0.48% average loss in September with positive price returns occurring only 45% of the time, both of which mark the worst of any month during the year. September also typically represents a volatile period for US stocks as the 0.88% standard deviation of daily price changes for the S&P 500 ranks second-highest after October,”

during every new S&P 500 closing high since 3/26/21, the median stock has been less than 12.1% away from its high.”
