Odaily Planet Daily News: Market research company SentimenTrader said that the U.S. stock market is about to end the hottest July in history. In this month, the S&P 500 index has set a new record high 10 times (the third best July since 1928), and the Nasdaq Composite Index has set a new record high 14 times. This kind of "super month" is rare in the summer. Historical data shows that after a similar surge in July, August becomes difficult. Historically, when the S&P 500 index sets at least 7 multi-year highs in July, the probability of its rise in August is only 36%, and the probability of rising in the next two months is less than half. The Nasdaq Composite Index has shown greater resilience, usually rebounding strongly after 4 months, but August still becomes like a gamble. (Golden Ten)
