Rachel Dashiell Charles Schwab notes a break in market breadth trends in the S&P 500 (SPX), though the amount of stocks trading above their 200-day SMA is improving. However, volatile downtrends amid lower volume across the index can push the S&P toward its 100-day and even its 200-day SMA. All that said, Rachel sees the possibility this also leads to a year-end rally based on historic trends. As for the Russell 2000 (RUT), Rachel shows how the index is testing a historically strong support level and warns of a death cross should price action break to the downside.
