1. GameStop (GME)
Transactions. President, CEO, and Chairman Ryan Cohen bought 1,000,000 shares at a weighted average price of $20.38 on September 10, committing $20,375,900. 1 Two days earlier, on September 8, director Lawrence Cheng purchased 55,000 shares through Cheng Capital LLC at $18.80, committing $1,033,956. 16 The two trades combine for $21,409,856 in total purchases, creating a coordinated board-level cluster.
Company context. GameStop released second-quarter 2026 financial results on September 8, reporting operating income of $160.2 million and raising its full-year adjusted EBITDA outlook above $650 million. The company held $5.4 billion in cash, marketable securities, and digital assets as of August 1, 2026. 21 The filings contained no Rule 10b5-1 pre-scheduled trading plan indicators.
Track record. Cohen has accumulated shares in multiple prior windows: he bought 1,000,000 shares at $21.36 on January 20, 2026, and 500,000 shares at $21.55 on April 3, 2025. 22 Cheng also bought 5,000 shares at $22.87 on January 23, 2026, and 5,000 shares at $21.54 on April 3, 2025. 23 Both insiders have consistently added shares in the $18–$23 range. A standardized six-month or twelve-month appreciation hit rate remains unknown due to the concentrated nature of their historical entries.
Current mark. GameStop shares traded at $21.15 in the September 14 pre-market snapshot, placing Cohen's entry up 3.80% and Cheng's entry up 12.50%. 2
Signal read. GameStop represents the largest conviction signal of the week by capital committed and combines the CEO with an independent board member immediately following earnings.
2. Uber Technologies (UBER)
Transaction. Chief Executive Officer Dara Khosrowshahi purchased 141,000 shares at a weighted average price of $70.96 on September 10, committing $10,005,952. 3 The purchase expanded his direct holdings to 1,367,100 shares.
Company context. The Form 4 disclosure reported direct open-market execution with no Rule 10b5-1 trading plan checkbox selected. Khosrowshahi's purchase followed recent weakness in the ride-share sector, where Uber shares traded down from late-summer levels near $80. 24
Track record. This trade represents Khosrowshahi's first recorded open-market purchase in his visible Uber Form 4 history. His prior Form 4 activity at Uber and Expedia consisted of option exercises and planned stock sales, including share sales above $95 in September 2025. 25 A historical six-month or twelve-month purchase hit rate is unknown because this is his debut buy.
Current mark. Uber shares traded at $71.67 in the September 14 snapshot, 0.99% above Khosrowshahi's $70.96 execution price. 4
Signal read. A rare eight-figure debut purchase by a sitting mega-cap CEO provides a strong individual governance signal, though it lacks companion open-market buys within the current trading window.
3. Inhibrx Biosciences (INBX)
Transaction. Chief Executive Officer Mark P. Lappe purchased 25,000 shares through the Lappe Family Trust on September 8, committing $2,645,399 across six price bands ranging from $98.88 to $112.44. 5 The weighted average execution price was $105.82.
Company context. Inhibrx Biosciences develops therapeutic biologic candidates for oncology and orphan diseases. The Form 4 contains no Rule 10b5-1 notation, confirming discretionary open-market accumulation. Two additional Inhibrx directors logged purchases on the same day: Jon Faiz Kayyem bought $567,580 and Douglas Forsyth bought $286,617. Those companion trades fell short of the individual $1M threshold and are tracked as company context. 26
Track record. Lappe previously bought 40,000 shares at $15.73 on September 12, 2024, committing $629,117. 27 That earlier entry appreciated substantially following corporate spin-off transactions. The limited total sample size leaves a standardized six-month or twelve-month hit rate unknown.
Current mark. Inhibrx shares traded at $109.27 in the pre-market snapshot, 3.26% above Lappe's $105.82 weighted entry price. 6
Signal read. Lappe's purchase represents a multi-million-dollar commitment alongside smaller board purchases, confirming company-wide insider interest.
4. Angel Studios (ANGX)
Transaction. Director Steven I. Sarowitz purchased 488,637 Class A shares across two consecutive sessions: 132,639 shares at $4.95 on September 9, and 355,998 shares at $5.28 on September 10. 7 The combined purchase value was $2,536,403 at a weighted execution price of $5.19.
Company context. Angel Studios operates a community-driven film and television distribution platform. The Form 4 indicated direct ownership with no Rule 10b5-1 trading plan checkbox selected.
Track record. Sarowitz has maintained an active accumulation campaign throughout 2026: he bought 353,815 shares at $3.83 on August 12 ($1,355,594), 57,922 shares at $4.26 on August 14 ($246,806), 10,979 shares at $4.27 on September 1 ($46,925), and 321,544 shares at $3.06 on May 5 ($982,574). 28 His purchases have consistently preceded price stability and subsequent upward adjustments, though a multi-year six-month or twelve-month hit rate remains unknown due to the recent listing history.
Current mark. Angel Studios shares traded at $5.45 in the snapshot, 4.99% above Sarowitz's $5.19 weighted entry. 8
Signal read. Sarowitz continues to build his direct ownership stake, providing steady capital support across consecutive quarters.
5. Alpha Metallurgical Resources (AMR)
Transaction. Director Kenneth S. Courtis purchased 10,000 shares of common stock on September 8 across six price tranches, committing $2,258,289. 9 Execution prices ranged from $223.45 to $228.14, establishing a weighted average price of $225.83.
Company context. Alpha Metallurgical Resources is a Tennessee-based supplier of metallurgical coal products to the steel industry. The purchase followed ongoing volatility in global metallurgical coal benchmark pricing.
Track record. Courtis is a documented serial accumulator in Alpha Metallurgical Resources. Over the past 12 months, Courtis purchased shares at $148.55 in September 2025, $175–$188 in December 2025, and $189.22 in May 2026. 29 His September 8 purchase pushed his direct ownership above 1.03 million shares. A formal multi-year hit rate remains unknown because his purchases occur within an ongoing accumulation strategy.
Current mark. Alpha Metallurgical shares traded at $209.41 in the snapshot, 7.27% below Courtis's $225.83 entry price. 10
Signal read. Courtis remains committed to long-term accumulation across commodity cycles, buying at current market prices despite recent downward share price pressure.
6. Cybin (HELP)
Transactions. On September 8, two senior executives filed concurrent open-market purchases: Chief Growth Officer Paul Glavine bought 100,000 common shares at $12.47 for $1,247,190, and Executive Chair Eric H. L. So bought 100,000 common shares at $12.39 for $1,238,670. 1315 Combined purchases totaled $2,485,860.
Company context. Cybin operates as a clinical-stage neuropsychiatry company developing psychedelic-based therapeutics and trades under the symbol HELP on the Nasdaq Stock Market. Both Form 4 filings noted voluntary submission by insiders not formally subject to Section 16 reporting requirements. Executive presentations were scheduled for the Morgan Stanley 24th Annual Global Healthcare Conference on September 14. 30
Track record. Both Glavine and So completed prior open-market purchases in late August and early September: Glavine bought 100,000 shares at $11.78 on September 3 and 90,000 shares at $11.59 on August 31; So bought 100,000 shares at $12.09 on September 4 and 95,000 shares at $11.81 on September 1. 3132 Standardized six-month and twelve-month appreciation outcomes are unknown due to the short time elapsed since the accumulation sequence began.
Current mark. Cybin shares traded at $12.97 in the snapshot, 3.99% above Glavine's $12.47 entry and 4.71% above So's $12.39 entry. 14
Signal read. Cybin displays coordinated executive accumulation ahead of investor conferences, with both leaders deploying personal capital across consecutive weeks.

Gu's current trade continues an averaging-down pattern at prices below prior purchase levels. A standardized six-month or twelve-month hit rate remains unknown.
Current mark. Upstart shares traded at $25.59 in the snapshot, 0.16% above Gu's $25.55 entry. 12
Signal read. Gu's repeated personal purchases below $28 provide a clear valuation anchor from the operating founder and CEO.
8. Alphatec Holdings (ATEC)
Transaction. Chief Executive Officer and director Patrick Miles purchased 115,000 shares at a weighted average price of $8.81 on September 10, committing $1,013,150. 17 Individual trade prices ranged from $8.73 to $8.84.
Company context. Alphatec develops surgical technologies for spine disorders. In its second-quarter results reported in August, revenue rose 15% year-over-year to $214 million, and management reaffirmed full-year 2026 guidance near $882 million. 35 The purchase followed a year-to-date share price decline of roughly 58%.
Track record. This trade is Miles's first recorded open-market code-P purchase in his visible Form 4 history. His filings in 2025 and early 2026 consisted of option-related sales. 36 A historical six-month or twelve-month appreciation hit rate is unknown.

Exclusions and classification notes
- Andrew Macdonald (UBER): Uber President and Chief Operating Officer Andrew Macdonald purchased 70,000 shares at $75.83 on September 4, committing $5,308,064. 39 While filed on September 8, the trade date sits outside the September 8–11 weekly window.
- Jeffrey K. Schomburger (TSN): Tyson Foods President and CEO-Elect Jeffrey K. Schomburger bought 19,450 shares at $51.50 on September 4, committing $1,001,617. 40 The trade date fell before the current screen window.
- United States Lime & Minerals (USLM): Candou Holdings Ltd. purchased 20,000 shares at $110.00 on September 9 for $2,200,000. Form 4 footnote 1 confirms that the shares were acquired in a private transaction, and Candou is a 10% beneficial owner entity rather than an operating executive or director. 41
- Institutional 10% owner filings: Republic Services (RSG) showed $324.3 million in purchases by Cascade Investment LLC, Group 1 Automotive (GPI) logged $64.3 million by Conifer Management LLC, and QVC Group (QVCG) logged $37.8 million by GoldenTree Asset Management. 26 These entities represent institutional asset managers rather than corporate executives or directors.
- Below-threshold purchases: Relmada Therapeutics (RLMD) saw CFO Maged Shenouda purchase $843,990 and CEO Sergio Traversa purchase $828,000; Carparts.com (PRTS) saw CEO David Meniane buy $882,534 and COO Michael Huffaker buy $881,757 across the week. 42 Each individual insider total remained below the strict $1 million qualifying cutoff.
Bottom line
The holiday-shortened trading week generated $44.63 million across 11 qualifying officer and director purchases. GameStop and Uber accounted for roughly seven of every ten dollars deployed, led by Ryan Cohen's $20.38 million order and Dara Khosrowshahi's $10.01 million purchase. GameStop and Cybin delivered clear multi-insider buying clusters, while Angel Studios and Alpha Metallurgical Resources demonstrated sustained accumulation sequences. Upstart, Alphatec, and PVH each added clean executive purchases following recent quarterly updates.
Nine of the 11 transactions registered positive unrealized marks in the September 14 pre-market snapshot, led by Alphatec (+20.09%) and Lawrence Cheng's GameStop purchase (+12.50%). These marks reflect short-term trading spreads rather than completed return horizons. A standardized six-month or twelve-month appreciation track record remains unknown for every retained insider due to small sample sizes or recent listing histories.
