Yahoo Finance reported on October 5, 2026 that GameStop shares were up about 35% over the prior month and that Ryan Cohen and four directors had reported open-market purchases with no matching sales in the article’s review period. A reproduced SEC Form 4 shows Cohen purchased 700,000 GameStop Class A shares on October 2, 2026, at a weighted-average price of $24.4061, with transactions ranging from $24.3600 to $24.4400.

The insider-purchase event is substantially verified: an independently reproduced SEC Form 4 records Ryan Cohen buying 700,000 GME Class A shares on October 2, 2026, at a weighted-average price of $24.4061, with transactions ranging from $24.3600 to $24.4400. The October 5 Yahoo Finance report also identifies purchases by four directors and describes a roughly 35% one-month rise.
The requested performance test cannot yet produce a result. October 5, 2026 is the observation start date, and only that completed session is currently available. A 20-session matched close-to-close comparison requires 20 subsequent completed U.S. sessions for both GME and SPY; those observations are necessarily unavailable at the retrieval time of October 5, 2026 17:51 UTC. The available bars show that GME closed at $25.745 on October 5 and SPY at $774.7003, but they do not establish subsequent outperformance.
Historical data show GME rising from $18.81 on September 1 to $25.745 on October 5, a calculated increase of approximately 36.9% over the available September 1-to-October 5 closes. The article’s reported approximately 35% one-month move is therefore directionally consistent with the retrieved bars. This is a price observation, not evidence that insider buying caused the move.
The SEC 8-K retrieved for September 8 concerns GameStop’s second-quarter results and does not itself document the October Form 4 purchase. The primary Form 4 URL supplied in the story could not be located through the targeted SEC search, so the exact SEC accession for Cohen’s October 2 Form 4 remains an unresolved primary-source gap. The reproduced Form 4 displayed by StockTitan matches the reported date, amount, price, range, transaction code, and post-transaction direct holdings, providing independent corroboration but not the same evidentiary status as directly reading the SEC-hosted Form 4.
The reported purchase value was approximately $17.08 million, calculated as 700,000 shares multiplied by $24.4061. Relative to the company, a complete materiality calculation would require a verified contemporaneous share count or market capitalization and a complete aggregate of all insider purchases in the article’s review period. Those inputs were not fully established from the retrieved primary record.
The conclusion would change when 20 subsequent matched regular-session closes for both GME and SPY are available. The relevant calculation is: GME return = (GME close on session 20 / GME close on October 5) − 1; SPY return = (SPY close on session 20 / SPY close on October 5) − 1; relative outperformance = GME return − SPY return. Corporate actions, if any, must be handled consistently.
Direct retrieval of the SEC-hosted Form 4 would strengthen event verification, while the complete Form 4 set for Cohen and the four named directors would be needed to verify the article’s broader “no matching sales” statement. Intraday records, options positioning, short interest, order-flow data, and a formal event study could help assess mechanism, but none would by itself prove causation.
Wait for the next 20 completed U.S. trading sessions and then run the prespecified matched close-to-close comparison. As of October 5, the evidence supports that the purchase occurred and accompanied a company-specific rally, but it is insufficient to determine whether GME outperformed SPY afterward.
The independently reproduced Form 4 identifies Cohen as GameStop’s president, CEO, chairman and director and records transaction code P for 700,000 shares acquired.

StockTitan reproduced SEC Form 4The retrieved closes were $18.81 on September 1 and $25.745 on October 5; calculation: 25.745 / 18.81 − 1 = 36.9%.
Polygon historical aggregates via SentimentorYahoo Finance’s fetched article states that Cohen and directors Nat Turner, Alain Attal, James Grube and Lawrence Cheng bought during the review period and reports GME up 35% over the month.
Yahoo FinanceCalculation: 700,000 × $24.4061 = $17,084,270, rounded to $17.08 million.
StockTitan reproduced SEC Form 4At retrieval time on October 5, 2026, only the October 5 completed session was available. The next 20 completed U.S. sessions had not occurred, so no valid forward matched-return comparison exists.
Polygon historical aggregates via SentimentorThe September 8 8-K reports second-quarter results and attaches an earnings press release; it does not document Cohen’s October 2 Form 4 transaction.
U.S. Securities and Exchange CommissionThe purchases and price increase overlap in time, but no event-study control, disclosure-time return decomposition, or causal identification was retrieved.
Yahoo FinanceWithout those matched closes, the explicitly requested forward relative-performance test cannot be calculated. Retrieval time was October 5, 2026 17:51 UTC.
The targeted SEC search did not return the Form 4, while the supplied SEC URL is an unrelated September 8 8-K. The reproduced filing is corroboration, not a direct SEC-hosted read.
This prevents a primary-source confirmation of the article’s assertion that all reviewed insider transactions were purchases with no matching sales.
The $17.08 million purchase can be quantified, but its percentage of equity value or insider ownership cannot be stated reliably from the retrieved primary record alone.
The data show temporal association only; isolating causation would require announcement-time returns, controls, broader market and sector factors, and ideally transaction-level information.
Question tested: From October 5, 2026, through the next 20 completed U.S. trading sessions, does GME outperform SPY using matched close-to-close returns?
The October 2 Cohen purchase and its price details are strongly corroborated, and GME’s preceding rally is visible in dated daily bars. However, the requested 20-session forward comparison cannot yet be answered because the observation window has not elapsed. Direct SEC Form 4 retrieval and 20 subsequent matched GME/SPY closes would change the assessment.
