Statistics show that the S&P 500's historical average return in week 37 was approximately 0.2%, higher than week 36's -0.4%. The "end of the summer lull" is mainly reflected in the increase in average trading volume from approximately $995 million to $1.04 billion, rather than an inevitable market downturn. Cboe data shows that the VIX traded in a low range of 14.25-16.50 in August this year, which is also consistent with the characteristic of suppressed volatility during the summer.
