AI-Selected Stocks Post Big Gains as S&P 500 Rally Accelerates

A concentrated set of model-driven equity picks has delivered double- and triple-digit moves amid a rare S&P 500 upswing

By Nina Shah HIMS TXN HRI IRDM

A narrow roster of model-selected stocks has posted outsized gains during a historic S&P 500 advance across April and May. Several names moved sharply in April and May, and a fresh June rebalance includes additional high-performing names such as Marvell and Penguin Solutions, which posted double-digit gains in the month. The selection strategy relies on a rules-based monthly rebalancing and equal-weighted portfolios derived from extensive historical financial data and quantitative models.

Key Points

  • A concentrated set of model-selected stocks delivered rapid, double- and triple-digit gains during a rare S&P 500 rally that saw the index rise over 16% across April and May.
  • June’s rebalance included notable short-term winners such as Marvell (MRVL) at +54.36% and Penguin Solutions (PENG) at +27.46%, with Veeco (VECO) flagged for a large order and meaningful revenue guidance uplift for FY2026.
  • The selection methodology evaluates thousands of equities using over 15 years of financial data and more than 150 quantitative models, producing up to 20 equal-weighted, high-conviction stocks per strategy and a monthly rebalancing process.

The S&P 500 climbed more than 16% over April and May - a level of market strength only observed four times since 1945. In that environment, a focused set of model-driven stock selections produced rapid gains that investors typically expect to see only over much longer periods.

Several large moves were recorded in April, where Hims & Hers Health (HIMS) rallied +48.14%, Texas Instruments (TXN) rose +37.29% and Herc Holdings (HRI) gained +32.52%. Those advances were followed by further breakouts in May, including Iridium Communications (IRDM) up +31.29%, HEICO Corporation (HEI) up +29.75% and IBM (IBM) up +29.20%.

June brought a new set of selections to members of a subscription research product, and early results for that month have been notable. Among June’s top performers so far are Marvell Technology (MRVL) at +54.36% in June alone, Penguin Solutions (PENG) at +27.46% for the month, Allegro MicroSystems (ALGM) at +13.77% and Veeco Instruments (VECO) at +11.20%.

More broadly, members had access to several additional 5%+ winners just days into June, underlining the concentrated, high-conviction nature of the portfolio approach. The strategy’s supporters note that positioning ahead of the broader market helped capture these moves prior to the rush of buying from more generalist investors.


Why some selections have jumped

The June rebalance included a selection tied to the semiconductor supply chain and related capital equipment. Veeco Instruments was highlighted for a combination of revenue acceleration and a comparatively modest valuation. The company reported a landmark order exceeding $250 million for indium phosphide laser equipment - an order explicitly connected to demand from expanding data center capacity.

That win is expected to underpin multi-year revenue growth, with product deliveries anticipated to accelerate into 2027. Management’s full-year 2026 revenue guidance of $740 million to $800 million represents a significant step up from recent trailing revenues of about $655 million, according to the information provided to members. Analysts covering the stock hold a consensus rating of Buy, with price targets noted up to $66 per share.

Proponents of the selection process point out that the position was established before this multi-year revenue cadence was broadly reflected in the stock price.


Examples of sustained performance

While week-to-week momentum can be compelling, the strategy emphasizes the compounding benefit of retaining high-conviction positions across multiple months. A sample of names that have produced multi-month gains for members includes:

  • Nucor (NUE) - +63.21% since selection
  • Consensus Cloud Solutions (CCSI) - +60.86% since selection
  • Texas Instruments (TXN) - +43.97% since selection
  • Molina Healthcare (MOH) - +41.96% since selection

Those returns form part of the performance track record presented for the strategy since the models were launched. Since November 2023, the stated cumulative return for the strategy is +240.30%, which is reported as outperforming the S&P 500 by +161.49% over the same period. These performance figures are identified as real-world numbers recorded since the official rollout of the models in November 2023.

How the selection process is described

The monthly selection methodology evaluates thousands of global equities using a mix of historical measures, valuation indicators and forward-looking growth signals. The process is said to process more than 15 years of financial data across over 150 quantitative models to identify up to 20 high-conviction stocks per strategy based on expected medium-term upside potential.

Each strategy is rebalanced monthly - new opportunities are added, strong performers may be retained and stocks that no longer meet the criteria are removed. To facilitate consistent performance measurement, each strategy applies equal weighting across all selected securities. Investors remain free to apply their own allocations, but the equal-weighting approach is used as a transparent benchmark for model evaluation.

The stated objective is to keep capital in companies that present a favorable combination of momentum, valuation and business performance.

Summary assessment

In the context of a rare S&P 500 rally, a compact slate of model-selected stocks has generated outsized returns in short order. The recent June rebalance produced particularly strong short-term moves in semiconductor-related names and a handful of other sectors. The selection process centers on a rules-based monthly rebalance, heavy reliance on historical financial datasets and a fixed equal-weighting approach to track and compare results.

Risks

  • Short-term volatility - Many of the highlighted gains occurred within weeks, indicating exposure to rapid reversals that can affect momentum-driven positions; this impacts technology and semiconductor-related stocks in particular.
  • Concentration risk - The approach focuses on a relatively small number of high-conviction names, which can increase idiosyncratic risk for investors compared with broader, diversified benchmarks; sectors such as industrials, semiconductors and healthcare may be disproportionately represented.
  • Performance persistence uncertainty - While historical model returns since November 2023 are presented, past performance does not guarantee future results and continued outperformance relative to the S&P 500 is not assured.
