S&P 500 Hits Record High — But September Risk Is Rising

After the S&P 500 broke above 7,800 for the first time on August 13, Wall Street’s technical strategists are warning that the rally may be entering a more vulnerable phase.

Record-high prices, extremely low volatility and strong investor optimism have created a market environment that leaves little room for disappointment.

The weakness beneath the surface is also worth watching. The Philadelphia Semiconductor Index remains more than 20% below its June peak, suggesting that parts of the tech sector are already under pressure.

Seasonality adds another risk. Since 1990, during U.S. midterm election years, the period from mid-August to mid-October has seen the equal-weighted S&P 500 fall about 6% on average, while the broader S&P 500 has declined around 5%.

That does not mean a correction is guaranteed.

But with valuations stretched and sentiment highly optimistic, investors may want to pay closer attention to volatility, market breadth and key technical support levels as September gets underway.

A record high can be a sign of strength — but when everyone is positioned for more gains, the market can become increasingly sensitive to bad news.
