Schwab clients were sellers of equities in April; Net selling was highest in the Information Technology, Consumer Staples, and Consumer Discretionary sectors

The Schwab Trading Activity Index™ (STAX) decreased to 41.18 in April, down from its score of 48.36 in March. The only index of its kind, the STAX is a proprietary, behavior-based index that analyzes retail investor stock positions and trading activity from Schwab’s millions of client accounts to illuminate what investors were actually doing and how they were positioned in the markets each month.

The reading for the four-week period ending April 25, 2025, ranks “low” compared to historic averages.

“Volatility was a huge story this month as the STAX fell to its lowest level in two years as Schwab clients were net sellers on a dollar basis of every S&P 500 sector except energy,” said Joe Mazzola, Head Trading & Derivatives Strategist at Charles Schwab. “Clients shied from individual stocks during April even as the S&P 500 and Nasdaq Composite boomeranged double digits from the April lows. As would be expected given the continued volatility in the markets, we saw a broad pattern of clients rotating out of equities and gravitating towards fixed income and broad-based ETFs as potentially lower-risk alternatives to individual names, using the spike in volatility not to run away from the market but to optimize their trading strategies with the opportunity afforded them.”

Amidst tariff policy announcements on April 2, stocks briefly went down to 13-month lows before the market made a dramatic comeback to recover much of those losses amid optimism for trade deal progression, Q1 earnings stability, and declining treasury yields.

The STAX fell every week of the April period, though the first week saw the heaviest selling as STAX fell 11%, the biggest weekly drop since the first week of April 2023. The third week of the four saw only mild net-selling but selling accelerated again in the final week ending April 25. On a monthly basis, April's overall STAX plunge of 14.85% was the deepest drop since March 2020, the first full month of the COVID-19 pandemic.

While clients didn't participate as much on the equity side, we did see selling of premium toward the end of the month as the CBOE Volatility Index® (VIX) pulled back from highs.

"We did see some ETF buying, which suggests that instead of trying to pick names that would do well with tariffs, clients decided to diversify," Mazzola said. "Clients were risk-averse, generally going back to names they know and companies that they tend to turn to in times of peril. Outside of NVDA, there was a noticeable absence of many of the AI chip providers that normally frequent this list."

Inflation data during the STAX period was relatively benign, continuing a trend, but investors nervously watched the Atlanta Fed's GDPNow meter for first quarter gross domestic product (GDP) fall into the red, suggesting tariffs already could be hurting the economy. When the government's first GDP estimate came out after the STAX period ended on April 30, it confirmed those fears, though much of the weakness was driven by a huge gain in imports that likely reflected pull-forward buying ahead of tariffs.

The labor market looked strong most of April, as March nonfarm payrolls rose a solid 228,000 and initial weekly jobless claims remained well below 230,000 all month, a relatively light level. Retail sales also popped in March, after faltering earlier this year. There's a chance some of this reflected pre-tariff stocking by consumers as expensive items like automobiles, electronics, and furniture sales all rose sharply.

Earnings season began in mid-April and featured solid results from the biggest U.S. banks, most of which referred to resilient consumers but expressed concern about possible tariff impact on business plans for their clients. However, analysts steadily cut their earnings growth estimates for later this year, calling into question current market valuations, which remain historically high even with the April stock market correction. Many other firms reported as well from across S&P sectors during the STAX period, with most beating Wall Street's estimates. But many withheld or withdrew guidance, citing tariff uncertainty.

Shakiness continued later in the STAX period as Treasury yields spiked and the dollar sank—two things that hadn't been expected in an atmosphere dominated by U.S. tariff concerns. The weakness in U.S. currency and fixed income markets might have reflected investors shying from these markets amid concerns about policy confusion related to both trade and the U.S. budget. Treasury note yields backtracked in the latter half of April, with the benchmark 10-year note yield eventually falling below 4.2% after touching 4.6% at its April highs.

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.
