The reading for the five-week period ending May 31, 2024, ranks “moderate low” compared to historic averages.

“As they were in April, Schwab clients were net buyers of equities during the May STAX period as they increased exposure to technology-related names, especially those related to Artificial Intelligence (AI) chip makers and the e-commerce and media companies that rely on them,” said Joe Mazzola, Head Trading & Derivatives Strategist at Charles Schwab. “Despite a significant amount of buzz, we didn’t see any of the so-called ‘meme stocks’ rising to the top of the most bought or sold names in May, although we did note that interest in those names was significantly greater among Schwab’s younger clients than it was across the general client population.”

U.S. equity markets rebounded from the volatile price swings that characterized the April period. Despite headwinds from key inflation measures and a brief spike above 4.60% in the 10-yr treasury yield, the S&P 500, the Dow Jones Industrial Average, and the Nasdaq Composite each notched new all-time highs in May. The Cboe Volatility Index (VIX) reversed direction from the April period, plummeting during the May STAX period from 15.03 to 12.92 - near historic lows. On May third, the U.S. Bureau of Labor and Statistics’ Employment Situation Summary showed nonfarm payrolls increased by 175,000 in April, well shy of the consensus 243,000 estimate, and later in the month on May 30, initial jobless claims came in at 219,000, slightly higher than the 218,000 expected. The unemployment rate was little changed at 3.9%. The Consumer Price Index (CPI) rose as anticipated by 0.3% for the month of April, bringing the 12-month increase to 3.4% before seasonal adjustment. The Producer Price index (PPI) came in at 0.5%, corresponding to a 12-month rise of 2.2%. U.S. Retail Sales was unchanged.

On May 31, Core Personal Consumption Expenditures (PCE) were reported at 2.8% versus expectations of 2.7%. The S&P 500 rose 3.48%, the Nasdaq Composite rose sharply by 5.07%, and the Dow Jones Industrial Average rose 1.7% during the May STAX period. The 10-year Treasury yield fell by 3.32% to close the period at 4.514, but not without a great deal of volatility during the period. The U.S. Dollar Index fell by 0.75%, closing the period at 104.67, and June Crude Oil Futures declined by nearly 7% to close the May STAX period at $76.99 per barrel.

About the STAX

The STAX value is calculated based on a complex proprietary formula. Each month, Schwab pulls a sample from its client base of millions of funded accounts, which includes accounts that completed a trade in the past month. The holdings and positions of this statistically significant sample are evaluated to calculate individual scores, and the median of those scores represents the monthly STAX.
