USA Insider Trading Pulse — July 22, 2026

USA Insider Trading Pulse

By Gunpowder Editorial ·

50 high priority 50 total filings analysed

Executive Summary

Today's insider trading pulse reveals a clear divergence between executive selling and buying, with notable insider sales at Sea Ltd, Sagimet Biosciences, and NewAmsterdam Pharma, while CEO purchases at 17 Education & Technology Group and Sterling Real Estate Trust signal management confidence.

The most significant insider sale is the $19M block trade by Franklin Resources in Clarion Partners Real Estate Income Fund, while the most material insider purchase is the $1.46M acquisition by Sterling Real Estate Trust's CEO. A cluster of negative sentiment surrounds biotech and tech names, with multiple insiders selling under 10b5-1 plans, suggesting pre-planned diversification rather than panic. On the positive side, insider buying at 17 Education, TSMC, and Hudson Technologies indicates selective conviction in undervalued names. The day's activity is dominated by equity awards and deferred compensation grants, which are neutral signals, but the raw selling volume far exceeds buying volume in dollar terms, creating a cautious near-term backdrop for the broader market.

Investment Signals (10)

  • CEO Liu Chang bought 9,287 ADS at $2.17 (~$20.1K), increasing holdings to 44,214 shares. This is a direct vote of confidence from the CEO at a low stock price, suggesting management sees value below $2.20.

  • Sea Ltd (BEARISH)

    COO Ye Gang sold $1.67M in shares at ~$106 under a 10b5-1 plan, while CCO Wang Yanjun sold an additional $99K. The COO's sale is material relative to his position, but the 10b5-1 plan reduces negative signaling.

  • TSMC (BULLISH)

    VP Lin Shyue-Shyh bought 2,000 shares at ~$73.4K total, a small but positive insider signal from a key executive at the world's leading semiconductor foundry.

  • Chairman & CEO Rogers sold 13,250 shares at $52.36 (~$694K), a material sale by the top executive at a regional bank. This could signal concerns about the bank's outlook or credit quality.

  • CAO Kooij sold 70,200 shares at $29.96 (~$2.1M) after exercising options at $11.17-$11.90, a classic 'exercise and sell' pattern that locks in substantial gains. The large volume relative to remaining holdings (24,353 shares) is a bearish signal.

  • CEO Happel sold $497K, CLO Rozek sold $81.8K, and Director Kemble sold $141K in a coordinated insider selling pattern. Three insiders selling on the same day at $7.46-$7.76 suggests a lack of confidence in near-term prospects.

  • CEO Regan bought 57,437 LP units at $25.50 (~$1.46M), the largest insider purchase today. This is a strong bullish signal from the CEO deploying personal capital at a 5.9% discount to the recent disposal price of $24.22.

  • 10% owner Control Empresarial sold 220,000 shares at $63.50-$64.35 (~$14.1M total), a significant reduction by a major shareholder in the refining sector. This could signal concerns about refining margins or the energy cycle.

  • 10% owner Hartree Partners bought 47,708 shares at $5.99 (~$286K), increasing its stake. This is a bullish signal from a sophisticated energy/commodities investor in the environmental services space.

  • Executive Chairman Camblong sold 20,000 shares at ~$6.32-$6.63 (~$133K) under a 10b5-1 plan, while also exercising options at $3.16. The net effect is a reduction in exposure, but the 10b5-1 plan tempers the negative signal.

Risk Flags (8)

  • Franklin Resources sold 1.68M shares at $11.29 (~$19M), a massive 24.8% reduction in its position. This is a high-conviction sell signal from a sophisticated asset manager.

  • Three insiders (CEO, CLO, Director) sold shares on the same day at $7.46-$7.76, totaling ~$720K. This coordinated selling pattern is a red flag for the biotech's near-term prospects.

  • CAO Kooij sold 70,200 shares, leaving only 24,353 shares remaining. The 'exercise and sell' pattern at a 168% gain from option strike prices suggests the insider is taking profits aggressively.

  • Control Empresarial sold 220,000 shares (~$14.1M) in two transactions, reducing its stake. This is a significant sell signal from a major shareholder in the refining sector.

  • Both COO and CCO sold shares under 10b5-1 plans on the same day, with combined proceeds of ~$1.77M. While pre-planned, the simultaneous selling by two top executives is noteworthy.

  • The CEO's $694K sale is material and comes at a time when regional banks face margin pressure and commercial real estate exposure risks.

  • COO Kirol sold 3,198 shares at $6.49 under a 10b5-1 plan. While small in dollar terms, insider selling at a depressed stock price ($6.49 vs 52-week high of ~$10) is a negative signal.

  • Todd Duchene sold 10,000 shares at $22.30 (~$223K) under a 10b5-1 plan. Given the volatile nature of the crypto mining sector, insider selling at these levels warrants monitoring.

Opportunities (8)

  • CEO Liu Chang bought shares at $2.17, near the stock's lows. With a market cap likely below $100M, this micro-cap could be a deep value play if the CEO's conviction is validated by fundamentals.

  • CEO Regan bought 57,437 LP units at $25.50, while recent disposals occurred at $24.22. The CEO is buying at a premium to recent trades, signaling strong conviction in the trust's asset value.

  • TSMC / Insider Buying at Key Executive Level (OPPORTUNITY)

    VP Lin bought 2,000 shares at ~$73.4K, a small but positive signal from a senior executive at the world's most advanced chipmaker. TSMC's AI-driven growth story remains intact.

  • Hartree Partners, a sophisticated energy investor, added 47,708 shares at $5.99 (~$286K). This buying at a ~$6 level suggests the stock is undervalued relative to Hartree's assessment.

  • Multiple directors and executives received equity awards, including the CEO (20,000 shares + options), COO (20,000 shares + options), and CFO (8,500 shares + options). This alignment of incentives through stock-based compensation is a positive governance signal.

  • 10% owner Chernett bought 18,000 shares at $5.27 (~$94.9K), increasing an already large position (10.6M shares). This insider buying at a single-digit stock price suggests confidence in the oncology services provider's turnaround.

  • John Hancock Funds / Insider Accumulation (OPPORTUNITY)

    Bacic William K bought shares in both John Hancock Diversified Income Fund (308 shares at $11.48) and John Hancock Financial Opportunities Fund (184 shares at $40.62). This dual purchase by the same insider signals value in the closed-end fund space.

  • President Weeks bought 92,000 shares at $0.05 (~$4.6K total), a micro-cap insider purchase. While the dollar amount is small, the volume (92K shares) shows conviction at a near-zero stock price.

Sector Themes (6)

  • Biotech Insider Selling Cluster

    Three biotech companies (Sagimet, NewAmsterdam, SOPHiA GENETICS) saw insider selling today, with combined proceeds of ~$2.8M. This suggests a sector-wide de-risking by insiders ahead of potential catalysts or data readouts. Investors should scrutinize upcoming milestones for these names.

  • Tech Insider Divergence

    While Sea Ltd and Peloton saw insider selling, 17 Education and TSMC saw insider buying. This divergence suggests selective opportunities in tech, with value-oriented names attracting insider capital while growth/momentum names see profit-taking.

  • Real Estate Insider Activity

    Sterling Real Estate Trust saw a large CEO purchase ($1.46M) while Clarion Partners saw a massive $19M sale by Franklin Resources. This dichotomy suggests a bifurcated real estate market where insiders see value in some segments (LP units) while others (REITs) face selling pressure.

  • Energy Sector Insider Selling

    PBF Energy's 10% owner sold $14.1M in shares, the largest sell-side transaction in the energy space today. This could signal concerns about refining margins, regulatory headwinds, or the energy cycle peaking.

  • Equity Awards as a Positive Signal

    Richardson Electronics awarded significant equity to its entire executive team (CEO, COO, CFO, EVPs), totaling 72,500 shares and 67,500 options. This broad-based compensation aligns management with shareholders and suggests confidence in future performance.

  • 10b5-1 Plan Dominance

    Multiple insider sales (Sea Ltd, Core Scientific, Peloton, SOPHiA GENETICS, Revvity, Sagimet, NewAmsterdam) were executed under Rule 10b5-1 plans. While these plans reduce the negative signaling of insider sales, the sheer volume of pre-planned selling today suggests insiders are systematically reducing exposure.

Watch List (8)

  • Watch for additional insider selling or a potential guidance update. Three insiders sold on the same day; if selling continues, it could signal a fundamental issue. Next catalyst: potential data readout for denifanstat in F2/F3 NASH.

  • CAO Kooij's near-complete exit (sold 74% of holdings) warrants monitoring. Watch for additional insider sales and the upcoming obicetrapib Phase 3 data readout, which could be a major catalyst.

  • Franklin Resources' 24.8% stake reduction is a major red flag. Monitor for further selling and the fund's NAV performance. The fund's next earnings call will be critical for understanding the outlook.

  • CEO Regan's $1.46M purchase is a strong bullish signal. Watch for additional insider buying and the trust's next property valuation update to confirm the CEO's conviction.

  • CEO Rogers' $694K sale is material for a bank CEO. Monitor for additional insider sales and the bank's Q3 earnings report for commentary on net interest margin and credit quality.

  • 10% owner Control Empresarial's $14.1M sale is a significant reduction. Watch for further selling and the company's next earnings call for refining margin guidance.

  • Hartree Partners' continued accumulation (now 5.04M shares) is a bullish signal. Monitor for additional purchases and the company's next quarterly report for refrigerant pricing trends.

  • The broad equity awards to the entire executive team suggest confidence. Watch for the company's next earnings report and any forward guidance that could validate the incentive alignment.
