Julian Emanuel, chief stock and quantitative strategist at Evercore ISI, believes that last Friday's sell-off is not completely over. Increased uncertainty and increased volatility may cause active funds, especially systemic funds, to reduce their holdings. He pointed out that the dispute over rare earth minerals on Friday catalyzed a late correction, and added that the cumulative increase of 36% in the S&P 500 index since its April low was already overbought. Year after year, market volatility in September and October has never been absent.
