SKN | Charles Schwab’s STAX Index Reveals Renewed Retail Risk Appetite Despite AI Volatility

Key Takeaways:

• Charles Schwab’s Trading Activity Index (STAX) rose to 61.94 in October, compared with 58.92 in September, indicating stronger buying activity among participating clients.
• Schwab observed a return to individual stock selection, with Information Technology attracting particular interest as clients bought shares during the AI-related selloff.
• Despite the higher index reading, only three of the S&P 500’s 11 sectors recorded net buying, while Schwab’s survey showed a decline in bullishness among its most active traders.

Charles Schwab reported a rise in its proprietary Schwab Trading Activity Index (STAX) for October, offering a detailed view of how its retail clients responded to market volatility and concerns surrounding artificial intelligence investment. The index increased to 61.94 from 58.92 in September, as investors returned to individual stocks after showing a stronger preference for exchange-traded funds (ETFs) the previous month.

The release is significant because Schwab is drawing on actual client account activity rather than relying exclusively on sentiment surveys or market commentary. Its analysis suggests that some investors viewed declines in technology and AI-related shares as opportunities to increase exposure. However, the data also reveals that this renewed appetite for equities was concentrated in a relatively narrow group of sectors.

Schwab’s STAX Measures What Clients Are Actually Doing

STAX is a proprietary, behaviour-based measure developed by Schwab to assess retail investor positions and trading activity across its extensive client base. The company evaluates a statistically significant sample of funded accounts that completed trades during the month. Individual account scores are calculated, with the median producing the monthly index reading.

For October, the higher score reflected increased buying activity and a shift back towards individual stock selection. Joe Mazzola, Schwab’s Head Trading Strategist, said clients had moved away from September’s preference for ETFs and returned to individual technology and AI-related shares that had declined amid funding concerns. He attributed part of this activity to expectations of a potential recovery in AI-related equities.

The distinction matters for Schwab because STAX provides an additional way to interpret how clients respond to changing market conditions. It also gives the firm a recurring view of differences between investor sentiment and actual account positioning.

Technology Buying Strengthened, but Sector Participation Narrowed

Schwab’s October data showed that Communication Services, Information Technology and Industrials were the only S&P 500 sectors in which clients recorded net buying. This compared with seven sectors in September, indicating that stronger overall activity did not translate into broader participation.

Among the individual securities attracting net buying were NVIDIA, Micron Technology, Alphabet and Intel. Microsoft, Tesla, Apple and Palantir were among the shares clients net sold. Schwab also reported that Generation X investors continued to lead net buying across demographic groups, while its more active traders reached their highest market exposure since the firm began tracking that segment more than two years ago.

Schwab’s November Survey Signals More Selective Confidence

A survey of more than 550 Schwab retail clients found that 19% were bullish on equities for November, compared with 17% in October. However, bullishness among the firm’s most active traders declined from 33% to 25%. The proportion willing to buy shares after sector declines also fell from 39% to 35%.

For international investors, Schwab’s findings highlight the difference between renewed buying and durable market confidence. The STAX is not a tradable index or a predictor of future market performance, and its retail-client sample should not be treated as a representation of all investors. Nevertheless, its sector and positioning data offer useful insight into changing risk appetite.
