USA Insider Trading Pulse — August 17, 2026

USA Insider Trading Pulse

By Gunpowder Editorial ·

50 high priority 50 total filings analysed

Executive Summary

Today's insider trading pulse reveals a stark divergence between aggressive insider buying in small/mid-cap healthcare and technology names versus systematic insider selling at Sea Ltd and Similarweb. The most concentrated buying event is at EDAP TMS SA, where six insiders—including the CEO, CFO, GC, and three directors—collectively purchased $490K at $4.75, signaling strong conviction at a potential inflection point.

On Holding AG saw its two top executives invest a combined $3.98M at $30.67, a rare and highly bullish signal from founders. Conversely, Sea Ltd's top five executives sold $3.8M via 10b5-1 plans, while Similarweb's CEO executed a $2.02M sale-and-exercise combo. Webster Financial's filings are dominated by routine tax-withholding share surrenders following equity awards, which are non-directional. The period-over-period data from the enriched filings shows no revenue or margin trends, as these are transaction filings, but the insider activity patterns themselves are the key signal: clusters of buying at beaten-down prices (EDAP, Aclarion, ACCESS Newswire) suggest bottom-fishing, while large-scale selling at Sea Ltd and Camtek warrants caution.

Investment Signals (10)

  • EDAP TMS SA ↓ (BULLISH)
    ▲

    Six insiders (CEO, CFO, GC, 3 directors) bought a total of 101,000 shares at $4.75 (~$480K). CEO Rhodes Ryan alone bought 21,000 shares. This is a coordinated, multi-executive buy at a single price point—extremely rare and highly bullish for a micro-cap.

  • On Holding AG ↓ (BULLISH)
    ▲

    Co-CEO Caspar Coppetti and Executive Officer Olivier Bernhard each bought 65,000 shares at $30.67, totaling $3.98M. Founder-level buying of this magnitude signals deep conviction in the company's growth trajectory and current valuation.

  • Borr Drilling Ltd ↓ (BULLISH)
    ▲

    Director Tor Olav Troim bought 500,000 shares at $4.39 (~$2.19M). Troim is the company's founder and largest shareholder; his purchase at a multi-year low is a strong vote of confidence in the offshore drilling cycle.

  • Sea Ltd ↓ (BEARISH)
    ▲

    Five top executives (President, Chairman/CEO, COO, CCO, Garena President) sold a combined ~$3.8M via 10b5-1 plans. CEO Li Xiaodong sold $797K, COO Ye Gang sold $1.43M. While pre-planned, the sheer volume and breadth of selling is a cautionary signal.

  • Similarweb Ltd ↓ (BEARISH)
    ▲

    CEO Offer Or sold 228,500 shares at $8.82 (~$2.02M) after exercising options at $3.04. This is a large, multi-trade sale by the top executive, representing a significant portion of his holdings.

  • Camtek Ltd ↓ (BEARISH)
    ▲

    Director Karni Yarl sold 3,176 shares at ~$164-$173 (~$522K), including an exercise-and-sell of 880 shares. The sale price near $172 is near the stock's 52-week high, suggesting profit-taking by an insider.

  • V F Corp ↓ (BULLISH)
    ▲

    Director Richard Carucci bought 20,000 shares at $14.73 (~$295K). This is a meaningful open-market purchase by a director at a stock that has been under pressure, signaling a potential value play.

  • Resideo Technologies ↓ (BULLISH)
    ▲

    President & CEO Thomas Surran bought 15,000 shares at $20.46 (~$307K). A CEO open-market purchase of this size is a clear bullish signal for the smart-home technology company.

  • Bitdeer Technologies Group ↓ (BULLISH)
    ▲

    Chief Strategy Officer Haris Basit bought 25,000 shares at $8.84 (~$221K). This is a first-time insider purchase for a relatively new executive, signaling confidence in the crypto mining company's prospects.

  • Aclarion, Inc. ↓ (BULLISH)
    ▲

    CEO Brent Ness and three directors collectively bought 36,006 shares at ~$2.31-$2.40 (~$85K). A micro-cap with multiple insiders buying at the same time is a classic turnaround signal.

Risk Flags (7)

  • Sea Ltd / Insider Selling Cluster↓ [HIGH RISK]
    ▼

    Five top executives sold ~$3.8M in a single day via 10b5-1 plans. While pre-planned, the coordination and size (especially COO Ye Gang's $1.43M sale) suggest insiders are taking chips off the table near $122-$125.

  • Similarweb Ltd / CEO Sale↓ [HIGH RISK]
    ▼

    CEO Offer Or sold 228,500 shares for $2.02M after exercising cheap options. This is a large, discretionary-looking sale (not a 10b5-1) that could signal a peak in management's confidence.

  • Camtek Ltd / Director Profit-Taking↓ [MODERATE RISK]
    ▼

    Director Karni Yarl sold 3,176 shares at ~$172, near the stock's high. The exercise-and-sell pattern suggests the insider views the current price as fully valued.

  • Nayax Ltd / Director Sale↓ [LOW RISK]
    ▼

    Director Eran Havshush sold 20 shares at $52.61. While tiny in size, any insider sale at a small company can be a negative signal, especially if it's the only insider transaction.

  • Talkspace, Inc. / Director Disposals↓ [MODERATE RISK]
    ▼

    Three directors (Warfield, Pawar, Benzur) disposed of a combined 622,340 shares and 169,789 options to the issuer. While these are likely part of a corporate restructuring or buyback, the volume is large and warrants scrutiny.

  • Webster Financial / Tax-Withholding Sales↓ [LOW RISK]
    ▼

    Eight executives had shares withheld for taxes totaling ~$5.3M at $79.07. While routine, the sheer volume of shares being surrendered (e.g., CEO Ciulla had 28,537 shares withheld) could create temporary selling pressure.

  • Cel Sci Corp / Option Grants↓ [MODERATE RISK]
    ▼

    CEO Geert Kersten was awarded 300,000 options at $0.01, and a director received 110,000. While not a direct sale, massive option grants at a penny strike can dilute existing shareholders significantly.

Opportunities (8)

  • EDAP TMS SA / Coordinated Insider Buying↓ (OPPORTUNITY)
    ◆

    Six insiders bought at $4.75, a single price point. This is a textbook signal of a potential turnaround or undervaluation. The stock is a micro-cap medical device company; the buying cluster suggests upcoming catalysts (e.g., FDA approval, new product launch).

  • On Holding AG / Founder Buying↓ (OPPORTUNITY)
    ◆

    Co-CEO and Executive Officer bought $3.98M at $30.67. On Holding is a high-growth athletic brand; insider buying at this level is extremely rare and suggests the stock is undervalued relative to its growth prospects.

  • Borr Drilling Ltd / Founder Accumulation↓ (OPPORTUNITY)
    ◆

    Director Tor Olav Troim bought 500,000 shares at $4.39. Troim is a well-known offshore drilling investor; his purchase at a cycle low is a strong contrarian signal for the energy sector.

  • V F Corp / Director Value Play↓ (OPPORTUNITY)
    ◆

    Director Richard Carucci bought 20,000 shares at $14.73. VF Corp (owner of Vans, The North Face) has been beaten down; a director buying $295K worth suggests the stock is near a bottom.

  • Resideo Technologies / CEO Vote of Confidence↓ (OPPORTUNITY)
    ◆

    CEO Thomas Surran bought 15,000 shares at $20.46. Resideo is a smart-home and security company; the CEO's $307K purchase is a strong signal that the current price is attractive.

  • Bitdeer Technologies / CSO First Buy↓ (OPPORTUNITY)
    ◆

    Chief Strategy Officer Haris Basit bought 25,000 shares at $8.84. This is his first insider purchase since joining, signaling confidence in the company's Bitcoin mining and AI cloud strategy.

  • Aclarion, Inc. / Micro-Cap Turnaround↓ (OPPORTUNITY)
    ◆

    CEO and three directors bought a total of 36,006 shares at ~$2.35. Aclarion is a tiny healthcare AI company; multiple insider buys at these levels suggest a potential re-rating or upcoming positive news.

  • ACCESS Newswire Inc. / CEO & Director Buying↓ (OPPORTUNITY)
    ◆

    CEO Brian Balbirnie bought 10,000 shares at $4.95, and Director Wesley Pollard bought 2,000 at $4.99. Combined $59.5K in insider buying at a stock near its lows is a bullish signal for this micro-cap.

Sector Themes (5)

  • Healthcare Micro-Cap Insider Buying Cluster (THEME)
    ◆

    EDAP TMS SA and Aclarion, Inc. both saw multiple insiders (CEO, directors, officers) buying stock on the same day. This pattern suggests a sector-wide belief that beaten-down healthcare micro-caps are undervalued.

  • Tech Insider Selling at Multiples (THEME)
    ◆

    Sea Ltd and Similarweb both saw top executives selling large blocks of stock. This is a red flag for the broader tech sector, especially for companies with high valuations or slowing growth.

  • Founder/CEO Buying in Consumer & Energy (THEME)
    ◆

    On Holding AG (consumer) and Borr Drilling (energy) both saw founder-level executives buying millions of dollars worth of stock. This is a rare and powerful signal that these sectors are at attractive entry points.

  • Routine Tax-Withholding Sales Dominate Financials (THEME)
    ◆

    Webster Financial's eight filings are all tax-withholding events following equity awards. This is a non-directional pattern common in large banks and should not be interpreted as bearish.

  • Director-Level Buying in Beaten-Down Industrials (THEME)
    ◆

    VF Corp and Resideo Technologies both saw directors/CEOs buying stock at multi-year lows. This suggests value investors are starting to accumulate in the industrial/smart-home space.

Watch List (8)

  • EDAP TMS SA↓ (WATCH)
    👁

    Watch for any press releases or FDA announcements following the coordinated insider buying at $4.75. The next earnings call could be a catalyst.

  • Sea Ltd↓ (WATCH)
    👁

    Monitor for any changes to the 10b5-1 plans or additional insider selling. If selling continues, it could signal deeper concerns about the gaming/e-commerce business.

  • On Holding AG↓ (WATCH)
    👁

    The $3.98M insider buy is a strong signal. Watch for Q3 earnings and any guidance raises. The stock could re-rate higher if growth continues.

  • Similarweb Ltd↓ (WATCH)
    👁

    CEO Offer Or's large sale warrants monitoring. If he sells more shares in the coming weeks, it would be a strong bearish signal.

  • Borr Drilling Ltd↓ (WATCH)
    👁

    Director Troim's $2.19M purchase is a bet on the offshore drilling cycle. Watch for day rates and fleet utilization updates.

  • Talkspace, Inc.↓ (WATCH)
    👁

    The director disposals to the issuer are unusual. Watch for an 8-K filing explaining the transaction or any changes to the company's capital structure.

  • Webster Financial↓ (WATCH)
    👁

    The tax-withholding sales are routine, but the volume is high. Watch for any insider open-market sales, which would be a more significant signal.

  • Camtek Ltd↓ (WATCH)
    👁

    Director Karni Yarl's sale near $172 is a potential top signal. Watch for additional insider selling or any negative pre-announcements.
