S&P

With the Nasdaq-100 losing momentum after months of artificial intelligence-fueled gains, options traders are increasingly positioning for a potentially significant move in small-cap stocks.

The S&P 500 posted its first monthly decline since March, ending a powerful stretch that had lifted equities to record highs, but still delivered a gain of more than 14% during the second quarter.

Layoffs at U.S. factories stood at the highest levels since the 2009 financial crisis, according to a new report.

The S&P 500 closed at a record on the final trading day of May, but only 20 companies in the index also reached their own all-time highs.
