The reading for the four-week period ending April 26, 2024, ranks “moderate low” compared to historic averages as investment exposure decreased.
“The April STAX period was marked by volatility as major indices took a breather from a five-month winning streak and had their worst month since September, despite solid corporate earnings,” said Joe Mazzola, Head Trading & Derivatives Strategist at Charles Schwab. “While Schwab clients were net buyers of equities, the investor enthusiasm that characterized the March results began to wane in April, pushing down the STAX score for the month. Clients were more discerning with their purchases, preferring to gravitate towards companies with strong fundamentals, particularly those with compelling generative AI solutions. Those companies continue to rank near the top of our client buy lists.”

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.
