How Retail Investors Are Shaping Markets

Retail Trading Volume Shifts:

• Retail participation in U.S. equity trading volume increased from a pre-pandemic baseline of 10–15% to 20–30% by early 2021.
• Single stock options market activity surged to four times its 2019 size by 2021, with retail investors estimating to control 50% of this market.
• The aggregate risk exposure held by retail investors in single stocks is estimated at approximately 40%, driven by the combination of share and levered options trading.
• A dramatic reversal in retail behavior has occurred over the last five months, characterized by a shift from net buying to net selling.
• Approximately 50% of the exposure accumulated by retail investors between 2019 and 2021 has been sold within the last five months.

Divergence in Investor Behavior:

• Retail day traders have largely abandoned the "buy the dip" mentality and are instead executing consistent, daily selling regardless of market direction.
• In contrast, "buy and hold" investors continue to deploy capital systematically into ETFs at a consistent rate through 2020, 2021, and into 2022.
• Retail allocation has shifted away from speculative individual stocks (tech, biotech) toward passive ETFs and value-oriented sectors, specifically energy.
• Institutional and hedge fund investors maintain a relative value and benchmark-focused strategy, distinct from the retail shift toward strategic re-allocation or profit-taking.

Market Liquidity and Structural Changes:

• Off-exchange trading volume rose from 35% pre-zero commissions to over 50% on certain days during the peak of the 2020-2021 retail boom.
• The migration of retail order flow to bilateral, off-exchange venues created "non-participable" volume, significantly increasing trading costs and market impact for institutional investors.
• Pre-market and after-hours trading have become less predictable for predicting next-day stock movements, with directional correlation dropping by nearly 50%.
• A complete cessation of IPOs and secondary offerings has removed a traditional tailwind for mass-affluent retail trading activity.
• Zero-commission models and gamification features are expected to sustain a new baseline of 15% retail participation permanently.

Sector-Specific Trends and Risks:

• Small-cap and low-dollar-priced stocks were heavily impacted by retail speculation in biotech and meme stocks, resulting in significant losses for many retail participants.
• The energy sector is currently attracting both professional and retail capital due to attractive valuations and improved balance sheets following previous downturns.
• Retail investors who were previously buying biotech stocks for "triple or quadruple" gains have largely pulled back from high-risk, binary-outcome positions.
• Recent data suggests some retail traders are exploring hedging strategies (e.g., long one stock, short another) rather than pure directional speculation.

Regulatory Outlook and Forward-Looking Statements:

• SEC Chairman Gensler has signaled interest in enhancing order-by-order competition for retail investors, potentially utilizing auction mechanisms to improve price discovery.
• Goldman Sachs expects no immediate rule implementations, anticipating a period of debate and evaluation regarding SEC proposals on tick sizes and best execution.
• Retail day traders are projected to remain a latent risk for single-stock herding events, with 80% of their weekly notional trading historically concentrated in just 100 names.
• Analysts do not anticipate a market-wide crisis driven solely by current retail selling, citing low unemployment and high household cash balances.
• Primary risks to future retail flows are tied to macroeconomic stressors, specifically if inflation outpaces wage growth, forcing households to divert funds from investments to consumption.
• The "systematic flow" of automatic 401(k) contributions is viewed as a stable force that is unlikely to reverse unless severe economic distress occurs.
