Report interpretation
Overview
J.P. Morgan's latest RetailRadar tracked U.S. retail investor trading behavior during the first week of May (April 30–May 6). The report notes that after a period of cautious observation in March and April, retail investors are now re-accumulating positions at an accelerated pace, focusing primarily on AI infrastructure and memory sectors. Fund flow data, social media sentiment, and options metrics all indicate that trading intensity for this theme has returned to levels last seen during the post-“Liberation Day” rally of the previous year.
Core views
Fund Flow Pace: Retail investors net-purchased $8.3 billion in the week, significantly above the 12-month average of $6.6 billion; ETFs received $6.0 billion, while individual stocks saw $2.3 billion. Overall activity has risen to the 77th percentile over the past year, though compared to the immediate “bottom-fishing” following last year’s Liberation Day, this round of inflows is more gradual. Theme Concentration: AI and memory remain the dominant themes. Social media monitoring shows peak discussion around semiconductor and memory-related stocks. On the ETF front, SOXX, SOXL, and QQQM continue to see net purchases, with DRAM ETF inflows quadrupling month-over-month; South Korean ETF EWY also experienced 2.2 times the standard deviation in inflows due to its AI exposure. Individual Stocks: The hardware sector posted the second-largest weekly retail inflow on record, with NVDA, META, and MSFT among Mag7 constituents still receiving net buys, though their spotlight has been eclipsed by storage and CPU companies like SNDK (4.5x standard deviation), MU (2.4x), and INTC (2.0x). LITE, ANET, STX, and other hardware names also attracted concentrated buying. Earnings Catalysts: AMD surged 16% after reporting strong results, prompting some retail profit-taking; SNDK, MU, and ARM were positioned ahead of earnings releases. In healthcare, LLY received an upgraded full-year guidance thanks to GLP-1 drug performance beyond expectations, yet retail inflows only reached 0.5x standard deviation. Meanwhile, industrial stock ETN saw data center orders jump 240% year-over-year, driving both share prices and retail capital flows upward. Options and Leverage: Retail options trading hit a record high, with TSLA, NVDA, MU, and AMD among the most active AI/memory-related options.
Analysis framework
The report employs a three-dimensional framework of ‘fund flows + sentiment + derivatives’: 1) Using brokerage clearing data to capture retail net purchases and Z-scores, measuring capital strength; 2) Leveraging social media heat rankings to validate thematic attention; 3) Combining options delta/gamma data to assess leverage and potential squeeze risks. By comparing ETF vs. individual stock flows, Mag7 vs. second-tier semiconductors, and different sector dynamics, the firm identifies the structure and rhythm of catch-up trading.
Methodology notes
Z-Score Fund Flow Intensity
The report uses Z-scores to normalize net purchase amounts, providing a clear view of how far capital deviates from the annual average, helping quickly identify unusual hotspots.
Comparison of Retail vs. Hedge Fund Holdings
By contrasting retail inflows with short interest changes in certain stocks, the report evaluates potential short squeezes or stampedes.

Impact & implications
The report concludes that although retail investors’ catch-up accumulation hasn’t matched last year’s rapid bottom-fishing, the intensity of capital flows and thematic concentration have returned to elevated levels, providing sustained buying support for AI and memory sectors. Should macro geopolitical and energy risks ease, retail sentiment could further strengthen; conversely, if markets correct, previously concentrated holdings may amplify volatility.
Risks
- If macro risks escalate, concentrated holdings may amplify volatility
- Unexpected swings in AI/memory cycle prices
What to watch
- Developments in geopolitical and energy crises
- Future trends in storage pricing
- Sustainability of retail capital inflows
