Citadel Securities strategist predicts retail investor pause in September

Citadel Securities' Scott Rubner reports that retail investors have maintained a significant bullish streak, being net equity buyers for 16 of the past 18 weeks and options buyers for 16 consecutive weeks, a trend he views as structural. Despite this sustained engagement, historical patterns indicate a likely temporary slowdown in September, typically the yearly low for retail participation, with buying activity expected to reaccelerate in the fourth quarter.

Analysis

According to research from Citadel Securities' Scott Rubner, retail investors have demonstrated a significant and sustained bullish sentiment, acting as net buyers of equities for 16 of the past 18 weeks and purchasing equity options for 16 consecutive weeks. This period of engagement marks the sixth longest bullish streak recorded since 2020. Rubner posits that this trend is a structural phenomenon reflecting strong consumer financial health and market engagement, rather than a cyclical or temporary fad. However, historical data since 2017 indicates a strong probability of a seasonal slowdown in this activity. Following robust participation in June and July, retail buying typically wanes in August and reaches a yearly low point in September, before reaccelerating in the fourth quarter.

Key Decisions for Investors

• Investors should anticipate a potential moderation in market liquidity and a possible increase in volatility in retail-favored stocks during September, which historically represents a low point for retail participation.
• Monitor for a re-acceleration of retail inflows in the fourth quarter, as a return to the recent bullish trend could provide a significant tailwind for the market heading into year-end.
• Consider the long-term thesis that elevated retail engagement is a structural, rather than cyclical, trend, which could imply a higher baseline of support for equities over the medium to long term.
