Retail investors have led this incredible market comeback. Goldman pinpointed their favorite stocks

Retail trading volumes have surged 28% since mid-April, with individual investors back driving the rally in U.S. equities. Goldman Sachs says retail now accounts for roughly 20% of total U.S. equity trading volume despite owning just 10% of market value, with AI enthusiasm pulling capital into high-growth names. Retail favorites such as Nvidia, Micron, and AMD are outperforming, though heavily traded names like American Airlines and Nu Holdings are still down this year.

Analysis

Retail re-entry is less about broad risk appetite and more about flow concentration: when incremental buying is crowded into a small basket of high-beta, high-gamma names, index-level upside can continue even if breadth deteriorates. That matters because these names are increasingly self-reinforcing through dealer hedging and leverage, so upside can extend for weeks once a momentum pocket forms, but the same structure makes drawdowns faster and less linear than in an institutionally led rally.

Within semis, the bigger second-order effect is not just AI enthusiasm but capital rotation toward the most liquid “AI beta” proxies. NVDA remains the cleanest sentiment barometer, while MU and AMD have more convexity to any shift in risk appetite because retail ownership tends to be stickier in winners and more reflexive in laggards trying to catch up. If leadership narrows further, semis can outperform the index in the short run even if earnings revisions flatten, but that also raises the odds of a sharp air-pocket when implied volatility cheapens and hedging demand fades.

The weaker retail favorites are useful as a sentiment tell rather than standalone fundamentals. AAL and NU show that retail can anchor falling knives for longer than fundamentals justify, but if those names fail to respond to a renewed risk-on tape, it signals the broadening of retail participation is shallow and that the rally is more fragile than headline highs suggest. In that setup, the trade is to fade the most crowded upside while keeping exposure to the highest-quality earnings compounders.

The main contrarian risk is that the market is underestimating how long retail leverage can keep marginal flows positive; this can persist for months if AI headlines stay frequent and realized volatility remains suppressed. The reversal catalyst is usually not bad news alone but a volatility event that forces deleveraging across leveraged ETFs and margin accounts, which would hit the most retail-exposed names first and then spill into the index. That creates a fast path to mean reversion rather than a slow grind lower.

Key Decisions for Investors

• Long NVDA / short AAL for a 4-8 week horizon: express the view that retail momentum is strongest in AI beta and weakest in low-quality cyclicals; target 1.5-2.0x payoff if the semi tape stays bid while airlines lag.
• Buy MU call spreads 2-3 months out: retail participation plus high operating leverage can keep the stock extended, but cap upside with spreads because the trade is vulnerable to a volatility reset once AI enthusiasm pauses.
• Tactically trim AMD into strength after sharp up days: it is a cleaner retail momentum name than a fundamental compounder, so risk/reward favors taking profit on spikes rather than chasing above recent highs.
• Use GS as a sentiment proxy long only on pullbacks, not breakouts: the setup benefits from higher market activity, but upside is limited versus semis; better as a low-beta flow beneficiary than a core momentum long.
• For contrarians, short a basket of retail-heavy laggards via put spreads on AAL and NU over 1-2 months: if breadth narrows or volatility rises, these names should underperform first and offer cleaner downside asymmetry than fighting NVDA directly.
