Since late 2024, retail traders have become even more active than they were in the years following the pandemic. At the end of last year, our retail data suggests retail trading reached $70 billion a day as markets rotated out of crypto and software stocks and into value stocks.
But in the past few weeks, as the conflict in Iran started, data shows retail trading has fallen significantly. Interestingly, so did the price of gold.
Gross trading falls as conflict continues
Amid the conflict, exchange-traded fund (ETF) activity has increased as ETFs are a natural way to play a macro event. However, retail saw reduced ETF activity (yellow line), which fell by around $5 billion per day.
Single stock retail trading tumbled even more — below $35 billion a day. After a ceasefire was put in place on April 8, stock flows rebounded above $40 billion a day.
Chart 1: Gross daily retail trading activity in stocks and ETFs over time
Notably, retail remained net-buyers of ETFs throughout the first quarter of 2026. Overall, retail bought more than $19 billion in ETFs in March and bought over $70 billion in ETFs during the first quarter.
However, data shows that retail traders were sellers of single stocks every single day in March. As a result, March saw net selling of over $15 billion — a record for the periods we have data for.

Single stock sector flows show a change in leadership
Looking at single stock flows by company each month, we see a change in leadership over the years.
Initially, Tesla was one of the most popular retail stocks, although between 2020 and 2023, Tesla buying and selling tended to follow the direction of the market (buying in up markets, green line, and vice versa).
In the past two years, NVIDIA has taken over as the most popular and most heavily bought stock.
Interestingly, as the conflict continued, net flows across all sectors turned negative, and buying and selling in NVIDIA fell to roughly balanced.

First significant dip in U.S. retail trading in years
Although retail trading has grown significantly since 2019, and net trading has fluctuated often with the direction of the market, this represents the first significant reduction in gross retail trading activity since 2021 — retail didn’t even have this strong of an immediate reaction to the war in Ukraine.

"The record net selling in March indicates that retail sentiment has shifted from speculative accumulation to structural distribution, removing a key liquidity floor for the S&P 500."
The retail retreat during the Iran conflict signifies a shift from 'buy-the-dip' retail exuberance to a more defensive posture, marking a potential psychological ceiling for market liquidity. While the article frames this as a temporary geopolitical reaction, the record $15 billion net selling in March suggests retail investors are finally rotating out of high-beta single stocks like NVDA into cash or safer yield-bearing instruments. This liquidity drain is critical; if retail remains net sellers even as volatility stabilizes, the market loses its primary support pillar for mega-cap tech valuations. We are seeing the end of the post-pandemic 'YOLO' retail cycle, which likely necessitates a valuation compression for growth-heavy indices.
Devil's Advocate
The retail retreat could simply be a tactical rotation into money market funds yielding 5%+, meaning this capital is sidelined rather than exiting the market, leaving it primed to flood back into equities at the first sign of a dovish Fed pivot.

"Retail's pivot to net ETF buying (+$70B Q1) amid single-stock selling reflects prudent derisking that enhances market resilience, not weakness."
Retail's gross trading plunge below $35B/day amid Iran tensions marks the sharpest dip since 2021, sharper than Ukraine's impact, but the April 8 ceasefire sparked a quick rebound above $40B, signaling transient fear. Critically, retail stayed net buyers of ETFs (+$70B Q1 2026, +$19B March), while dumping single stocks (-$15B record March)—a derisking rotation to diversified exposure, not exodus. NVDA flows balanced out, hinting cooling on AI hype. This maturation bodes well for market stability over retail-FOMO volatility, though broker stocks like HOOD may feel near-term pinch from lower gross volumes.
Devil's Advocate
If conflict escalates beyond the ceasefire, record single-stock selling could snowball into broader risk-off, hitting even ETFs as retail liquidity dries up faster than in past events.

"Retail's shift from single stocks to ETFs during the Iran conflict reflects rational portfolio rebalancing, not capitulation, and the April 8 rebound suggests the dip was tactical rather than structural."
The article conflates two separate phenomena—a tactical retreat from single stocks during geopolitical uncertainty and a structural shift in retail behavior—without distinguishing them. Retail sold $15B net in March but remained net-buyers of ETFs ($19B that month alone), suggesting not panic but rational de-risking: swapping concentrated bets for diversified exposure. The ceasefire bounce validates this as tactical, not structural. The real signal is the NVIDIA flow collapse to 'balanced'—that's not fear, that's saturation. After two years of relentless buying, retail may simply be rotating, not fleeing. Gold's decline actually contradicts the 'safe haven' narrative the headline implies.
Devil's Advocate
If retail is truly rotating tactically, why did gross trading fall $5B/day in ETFs rather than merely shift composition? That suggests genuine demand destruction, not repositioning—a sign of confidence erosion that could persist beyond the ceasefire.

"Retail trading deceleration is not inherently bearish; ETF/option-driven activity can keep price action supported even as stock-picking dries up."
Initial read: retail enthusiasm cooled as geopolitical risk around Iran kept risk-off impulses, yet ETF flows remained positive and March saw heavy net selling in individual names even as ETFs bought. The missing context is whether this is seasonal/quarter-end rebalancing or a structural shift toward passive and hedging. The drop in gold price challenges a simple safe-haven narrative, suggesting yields or dollar dynamics may be driving flows. Also, the data window is early 2026 and may not capture later volatility; if institutional buyers or AI beneficiaries still draw in liquidity, the macro backdrop could keep the market supported even if stock-picking dries up. Caution about extrapolating retail sentiment into future returns.
Devil's Advocate
But the strongest counter: the data could reflect a structural shift away from active stock picking by retail; if options volumes surged, retail hedging could dominate without showing up in gross stock flow, meaning risk sentiment could be deteriorating even as ETFs shine.

"The rotation into ETFs is not true de-risking but a concentration trap that exacerbates market vulnerability to mega-cap volatility."
Claude and Grok are missing the second-order effect of retail moving from single stocks to ETFs: it forces a market-cap-weighted concentration trap. As retail liquidity flows into SPY or QQQ instead of individual names, they are inadvertently fueling the mega-cap tech dominance they think they are 'diversifying' away from. This isn't de-risking; it's passive indexing that reinforces the very valuation extremes that make the market vulnerable to the next geopolitical shock.

"Retail's single-stock selling exacerbates small-cap underperformance amid ETF rotation, risking persistent dispersion without FOMO return."
Gemini's ETF concentration trap nails it, but nobody flags the small-cap casualty: retail's $15B single-stock dump disproportionately hits non-mega names (ex-NVDA), widening IWM-SPY spread without FOMO fuel. Ceasefire rebound may lift tide, but small caps lag unless retail rotates back—true derisking leaves dispersion (Russell underperf 25%+ YTD) unhealed, pressuring BKX banks on credit risk.

"Retail single-stock selling doesn't explain small-cap underperformance; institutional mega-cap rotation does."
Grok and Gemini both assume retail single-stock selling hits small caps hardest, but the data doesn't support this. March's $15B net dump was concentrated in mega-cap tech (NVDA, TSLA)—retail doesn't hold Russell 2000 names in size. The IWM-SPY spread widened because institutions rotated into mega-cap AI plays, not because retail abandoned small caps. Small-cap underperformance is a separate macro story (rate expectations, credit spreads), not a retail flow casualty. Conflating the two obscures what actually matters: whether institutional money stays in mega-cap tech.

"ETF flows can mask risk; in a stress event, ETF liquidity can evaporate, triggering rapid drawdowns and a liquidity cliff even when net ETF inflows look positive."
Responding to Gemini: I share the concern that ETF flows can reinforce mega-cap dominance, but the risk hinges on liquidity, not just concentration. In a real stress event, ETF liquidity can evaporate as underlying markets seize up, forcing rapid drawdowns even if net ETF flows were positive in March. So the real danger isn't 'passive = safe'—it's a potential liquidity cliff that could blow out dispersion and hit index levels faster than expected.
