Stephen Andrew Cohen

Stephen Andrew Cohen sold 319,934 shares of PLTR for $43,524,501.18 across 5 transactions on 2026-05-20, reducing holdings by 99.8%.

Stephen Andrew Cohen executed five separate sales totaling 319,934 shares for $43,524,501.18 on 2026-05-20, at prices ranging from $132.95 to $136.61 with a blended average of $136.04. The transaction reduced his holdings from 320,526 shares to 592 shares, representing a near-complete exit from his PLTR position. This massive, coordinated liquidation stands out sharply against his prior trading pattern at PLTR: his five most recent sales at this ticker (all on 2026-02-20) were substantially smaller and have historically underperformed on a 90-day basis, with none showing the negative 90-day returns that would indicate well-timed selling. His cross-ticker track record shows a 75.00% well-timed rate on sells, yet his PLTR-specific history shows 0 of 5 prior sells were well-timed at the 90-day mark, suggesting his timing discipline has not historically transferred to this security. The stock is trading at -34.0% from its 52-week high and -10.3% down over the past 30 days, providing context for the scale of this exit but not yet determining whether the transaction will prove prescient or premature.

Cohen executes 5 sales of 327,088 PLTR shares at $133.72 avg price for $43.7M, retaining 592 shares post-transaction

Cohen Stephen Andrew executed 5 separate sales on 2026-02-20 totaling 327,088 shares at a blended average price of $133.72, generating $43,737,696.00. This represents a 99.8% reduction in his open-market PLTR holdings, leaving 592 shares post-transaction. The current stock price of $128.84 is 37.8% below the 52-week high and down 24.0% over 30 days, marking a pronounced decline since the transaction date. Notably, Cohen's prior 5 trades at PLTR (all sales in late November 2025) demonstrated a 5 of 5 well-timed pattern at the 90-day mark, with all five showing negative 90-day returns after execution. The timing context of this large-scale divestiture against a backdrop of recent equity weakness and his established track record of well-timed exits at this ticker merits investor attention, though the FLAG notation regarding derivative holdings indicates the Table I shares post-transaction do not capture his full securities position.

Cohen sells 347.8K PLTR shares (99.8% of holdings) across 22 transactions for $56.7M; blended avg $163.12 vs current $162.25.

Stephen Andrew Cohen executed 22 separate sales totaling 347,771 shares for $56,726,863.91 on November 20–21, 2025, reducing his holdings from 348,363 to 592 shares and leaving him with minimal residual position. The blended average sale price of $163.12 marginally exceeded the current price of $162.25, suggesting the bulk of the liquidation occurred near or at market support levels. Notably, Cohen's prior PLTR sales on August 20–21, 2025 resulted in negative 90-day returns (ranging 5.2%–16.4%), indicating stock performance reversed post-sale; however, this filing involves derivative conversion (Form 4 Table II not yet populated), so the reported 592 shares post-transaction do not reflect his full derivative or economic position. The scale of this transaction—departing from his prior PLTR pattern of smaller, sequential disposals—warrants attention to whether the derivative conversion reflects scheduled exercises or a material shift in position structure.

Cohen sold 351,884 shares of PLTR for $53,966,068.39 across 18 transactions on 2025-08-20/21, reducing stake to 592 shares.

Cohen executed 18 separate open-market sales totaling 351,884 shares for $53,966,068.39 at a blended average price of $153.36, virtually exiting his position (from 352,476 pre-transaction shares to 592 post-transaction). At PLTR specifically, his prior 5 recorded sales over the past three months all resulted in positive 90-day returns (+24.4% to +37.9%), meaning the stock rose after each sale—none of these prior sales were well-timed on a 90-day basis. The current price of $158.74 stands above the blended sale price of $153.36, consistent with this pattern. While this large-scale reduction in PLTR holdings is factually dramatic, the absence of timing discipline in his prior PLTR exits (0 of 5 were well-timed; average 90d return +25.9%) and the current price remaining above his sale prices suggest the sales did not anticipate a near-term decline.

Cohen sold 344,053 shares for $43,471,357.51 across 7 transactions on 2025-05-20 to 2025-05-21 at $126.35 avg price.

Stephen Andrew Cohen executed 7 separate sales totaling 344,053 shares for $43,471,357.51, representing a 99.8% reduction of his holdings at Palantir Technologies. The transaction occurred at a blended average price of $126.35 across May 20–21, 2025. Cohen retains only 592 shares post-transaction. A FLAG in the filing indicates this involves a conversion of derivative securities; his Table II derivative holdings are not yet populated in the database, meaning the 592 shares in Table I may not represent his full economic position. The stock has since declined 6.1% from its 52-week high of $130.18 and currently trades at $122.29, though it remains up 30.1% over the past 30 days and 20.7% over the past 90 days. His prior five same-ticker sales (all on 2025-03-17) showed positive 30-day returns ranging from 4.6% to 8.8%, though 90-day outcomes are not yet measurable for those trades.

Cohen sold 310,000 PLTR shares for $27.0M across 5 transactions on 2025-03-17, retaining 592 shares post-sale.

Cohen Stephen Andrew executed 5 separate sales totaling 310,000 shares for $26,991,578.27, with a blended average price of $87.07. The filing contains a derivative-conversion flag, indicating these shares originated from derivative security conversion rather than a direct position exit; the insider retains 592 shares and holds additional positions in Table II derivatives not yet populated in the database. The sales occurred as PLTR trades at $86.10, down 30.9% from its 52-week high of $124.62 and down 27.7% over the prior 30 days, despite a +16.0% gain over 90 days. Cohen's prior 5 trades at PLTR were all sales on 2025-03-14 (three days prior), suggesting a pattern of systematic liquidation of converted derivative positions across consecutive trading days.

Cohen sells 3,750,000 PLTR shares for $310,248,337.23 across 16 transactions (Mar 12–14); conversion of derivative securities.

Stephen Andrew Cohen executed 16 separate sales totaling 3,750,000 shares for $310,248,337.23 between March 12 and March 14, 2025, with a blended average price of $82.73. The filing is flagged as a derivative-conversion transaction rather than a full exit, meaning the insider's complete position resides in Form 4 Table II (derivative securities) not yet populated in the database; the post-transaction holding of 592 shares does not represent total remaining position. The stock has declined 26.5% over the past 30 days and trades 30.8% below its 52-week high of $124.62, creating context of significant downward momentum during the sale window. Across Cohen's cross-ticker track record, prior sells averaged a negative 90-day return of -8.5%, suggesting his historical sales timing has been generally favorable (negative returns after selling = well-timed), though his 90-day well-timed rate at 0.00% indicates recent sales have not followed this pattern.

Cohen sold 675,000 PLTR shares for $69.3M (blended avg $102.62) on 2/20-2/21; post-sale holdings 592 shares.

Cohen Stephen Andrew executed 18 separate sales totaling 675,000 shares for $69,269,087.91 across two trading sessions (2025-02-20 to 2025-02-21), reducing his position from 675,592 shares to 592 shares post-transaction. This represents a reduction of 99.9% of his pre-transaction holdings. The FLAG notes this is a derivative-conversion transaction; the insider's full position lives in Form 4 Table II derivative holdings not yet populated, so these Table I shares do not represent a complete position exit. At current price of $90.68, the stock has declined 27.2% from its 52-week high of $124.62 where many of these sales occurred (blended average transaction price $102.62). His prior five trades at PLTR (all in December 2024) each showed negative 30-day returns (-8.0% to -11.3%), though those outcomes remain incomplete at the 90-day window.

Cohen sells 1,316,053 shares across 13 transactions for $95,838,066.80; derivative conversion flagged

Cohen Stephen Andrew executed 13 separate sales totaling 1,316,053 shares for $95,838,066.80 between December 11–13, 2024, at prices ranging from $68.83 to $75.85, with a blended average price of $72.82. The sale represents a conversion of derivative securities rather than a full-exit liquidation; the insider retains 592 shares post-transaction, and his actual position lives in the derivative holdings table not yet reflected in this filing. Within his cross-ticker track record, Cohen's prior 20 open-market sells achieved a 90-day well-timed rate of 28.57% (only 28.57% of those sales preceded stock declines), and his average 90-day return after prior sells was +34.9%, indicating those sales were poorly timed relative to subsequent price appreciation. At PLTR specifically, his 5 prior trades from November 2024 have not yet reached measurable 90-day outcomes. The sale occurred as PLTR trades near its 52-week high of $76.34 (current price $76.07, +25.3% over 30 days and +113.7% over 90 days), suggesting the insider chose to monetize amid strong momentum; however, absent clarity on the derivative conversion's scheduled or discretionary nature, timing motivations remain observational rather than prescriptive.

Cohen sells 348,809 shares (348.8K) of PLTR for $21,555,678.08 across 6 trades; retains 592 shares post-transaction

Cohen Stephen Andrew executed 6 separate sales totaling 348,809 shares for $21,555,678.08 over two trading days (2024-11-20 to 2024-11-21) at a blended average price of $61.80, reducing his PLTR holdings from 349,401 shares to 592 shares. This represents a 99.8% reduction of his pre-transaction position. The stock now trades at $64.35, and over the prior 30 and 90 days has rallied +51.1% and +102.5% respectively, near its 52-week high of $65.77. A FLAG indicates this filing involves a derivative conversion (Table II) that is not yet populated in our database—his retained 592 shares may not represent his true economic position. His same-ticker history at PLTR shows five prior sells, all of which produced positive returns at both the 30 and 90-day marks (0 of 5 were well-timed in the traditional sense). Investors should monitor Form 4 Table II when available to understand the full scope of his derivative holdings and any offsetting positions.
