According to Oppenheimer statistics, since 1950, when the S&P 500 enters September above its 200-day moving average, it has averaged a 0.2% monthly gain; if it falls below the moving average at the beginning of the month, it has averaged a 3% decline. As of August 31, the index closed at 7686 points, about 8% higher than the 200-day moving average of 7123 points, showing no immediate trend reversal. However, the success rate of closing above the moving average is only 50%, with an average return of only 0.2%, indicating that the "September curse" has weakened significantly, but has not yet created a strong positive return advantage. The S&P 500 price index rose about 2.6% in August, with a total return including dividends of 2.72%. The continuous rise itself has increased short-term profit-taking pressure.
