When insiders load up on their own stock with serious capital, it historically signals conviction. An Insider Score reflects the consistency, scale, and timing of insider purchases relative to public float and volatility. Stocks with Very Strong and Strong Insider Scores may suggest that company leadership believes the stock is undervalued or positioned for upside. Here are the five names with the highest insider conviction right now, based on our Insider Score feed and recent SEC Form 4 filings.
1. BLSM — Very Strong Conviction in Healthcare Play
BlossomHill Therapeutics, Inc. carries a Very Strong Insider Score, the highest conviction band on this list. Insiders have accumulated $25.2M in purchases, reflecting significant confidence in the therapeutic pipeline. This scale of insider buying, concentrated in a healthcare name, may suggest leadership believes the current valuation does not reflect the potential of its development programs.
2. PNAQ — $29.8M Insider Buying in SPAC Structure
Pinnacle Acquisition Corp shows a Strong Insider Score with $29.8M in total insider purchases—the largest dollar volume on this list. SPAC structures can attract significant insider capital when sponsors believe in the merger target. The scale here may indicate confidence in the eventual business combination or the terms already agreed.
3. TLSA — Healthcare Name With Sustained Insider Support
Tiziana Life Sciences Ltd carries a Strong Insider Score supported by $1.04M in insider purchases. The healthcare sector concentration in this top-five list underscores that insider buying pressure is flowing into life sciences and therapeutic names. Investors may want to monitor whether insider accumulation continues as development milestones approach.
4. FEMY — Smaller Dollar, Strong Insider Score
FEMASYS INC rounds out the healthcare trio with a Strong Insider Score, despite a more modest $134K in insider purchases. Per our Insider Score feed, the score reflects not just dollar volume but also the proportion of insider buying relative to float, frequency of purchases, and price momentum. A Strong score on lower absolute dollars may indicate concentrated insider conviction in a smaller-cap or lower-priced name.
5. NTHI — Pharmaceutical Preparations Play
NEONC TECHNOLOGIES HOLDINGS, INC. carries a Strong Insider Score with $458K in insider purchases. The pharmaceutical preparations sector classification places it alongside other healthcare bets on this list, reinforcing a thematic preference for life sciences among insiders this period.
The Bottom Line
All five of these names have earned a Strong or Very Strong Insider Score based on the consistency and scale of insider capital deployed. These are not guarantees of stock performance, but they may suggest that company insiders believe their stocks are priced attractively relative to near-term catalysts or longer-term value.
