Citadel Securities’ Rubner Sees Retail Traders Pausing Stock Buying

Citadel Securities' head of equity and equity derivatives strategy, Scott Rubner, anticipates a temporary slowdown in retail stock buying during September, following a sustained period of significant activity. Retail traders have been net buyers of equities in 16 of the past 18 weeks and net buyers of equity options for 16 consecutive weeks—the sixth longest such streak since 2020, according to Citadel's data. Rubner expects this purchasing trend to resume later in the year.

Analysis

A key strategist at Citadel Securities, Scott Rubner, forecasts a temporary slowdown in equity purchases by retail investors during September, potentially interrupting a significant source of market support. This prediction is contextualized by a period of intense buying activity, where retail traders have been net purchasers of equities in 16 of the past 18 weeks. Furthermore, their net buying of equity options has persisted for 16 consecutive weeks, marking the sixth longest bullish streak of its kind since 2020. While a near-term pause is anticipated, Rubner's outlook suggests this is a temporary consolidation, with a resumption of retail buying expected later in the year, indicating that underlying bullish sentiment may return.

Key Decisions for Investors

• Investors should anticipate a potential increase in short-term market choppiness or a lack of directional conviction in September, as a key source of buying pressure may temporarily recede.
• Monitor retail flow metrics and options market data closely over the next month for confirmation of this pause and for early signals of the predicted resumption in buying activity.
• A market dip in September driven by reduced retail participation could present a tactical entry point for those aligning with the view that buying will resume later in the year.
