STORY: Stovall noted: “While many people highlight the positive aspect of seasonality [the stock market]…It doesn’t always go up.”What “worries” him, he explained, is this: “If you look at the relative performance of the S&P 500 pure growth and S&P 500 pure value indexes, growth peaked in August and has been giving up its relative strength, its outperformance, for some time.”He added that the S&P 500 pure growth index “is currently trading below both its 50- and 200-day moving averages.”
