Significance 5/10

BX director Porat Ruth buys 439 shares on open market as stock trades well below 52-week highs amid mixed track record at this ticker.

Director Ruth Porat purchased 439 shares of Blackstone in three separate transactions, building on her existing substantial position in the company. The purchases occurred while the stock trades significantly below its 52-week high, presenting what could be viewed as a buying opportunity in a fundamentally profitable and growing company. However, Porat's track record at this specific ticker is decidedly mixed: over the 90-day timeframe, all five of her prior purchases at Blackstone were followed by declines, while the 30-day view shows more balance with two showing gains and three showing declines. This sixth buy at Blackstone follows a pattern of repeated accumulation (she has now made eight open-market purchases at this ticker in the 36-month window), yet her prior transactions at this same company have not vindicated her timing — she has never successfully timed a BX purchase on the 90-day horizon. The stock has also declined modestly over the past month and quarter, suggesting the director is buying into a period of near-term weakness rather than momentum.

Significance 4/10

Director Porat Ruth bought 524 shares at blended $130.68 in 3 purchases; stock now $121.27, down 22.2% in 30 days.

Porat Ruth, a Director at Blackstone, executed 3 separate open-market purchases totaling 524 shares for $68,553.25, increasing her shareholding from 8,338 to 8,862 shares (+6.3%). The purchases occurred at an average price of $130.68 on February 17, 2026, but the stock has since fallen to $121.27, representing a 22.2% decline over 30 days and a 35.7% drop from its 52-week high of $188.68. Her prior transaction history at BX is instructive: across 5 previous purchases at this ticker, 0 of 5 were well-timed at the 90-day mark, with an average 90-day return of -11.8% (composite of the posted 90d figures). This latest purchase aligns with that pattern rather than signaling market-beating conviction at this price level.

Significance 6/10

Director Porat Ruth buys 402 BX shares (3 transactions) for $58,835.43 at blended avg $146.24 amid 29.9% pullback from 52-week high

Director Porat Ruth completed three separate purchases on 2025-11-10 totaling 402 shares for $58,835.43 ($58.8K) at a blended average price of $146.24, bringing holdings to 8,763 shares. The transaction occurs as Blackstone trades at $139.53, down 29.9% from its 52-week high of $199.05 and off 14.9% over the past 30 days. Prior BX trades by this director show mixed outcomes: three August 2025 purchases gained modestly in the near term (+4.5% to +5.0% at 30 days) but declined 14.0–14.5% by 90 days, while two May 2025 purchases posted stronger 90-day returns (+24.2% to +25.4%). The timing pattern at this ticker is matched discretionary open-market purchases against recent price deterioration, though historical execution at BX has been uneven—only 2 of 5 prior same-ticker trades achieved positive 90-day returns.

274 shares

Significance 7/10

Director Porat Ruth purchases 274 shares across 3 transactions for $46,698.68 total at BX, raising stake to 8,685 shares

Director Porat Ruth executed 3 separate purchases totaling 274 shares for $46.7K on 2025-08-11 at blended average price $170.19, increasing her BX holdings from 8,410 to 8,685 shares (+3.3%). The timing is notable: the stock currently trades at $176.62, up 8.1% over the prior 30 days and +20.4% over 90 days, positioning this purchase near recent strength. Across her open-market history spanning multiple tickers, Ruth's 14 prior buys averaged +1.6% return over 30 days and +11.4% over 90 days with a 78.57% win rate at the 90-day mark. At BX specifically, 3 of her 5 prior trades demonstrated positive 90-day returns, with her May 2025 buys each returning +25.4% and +24.2% over 90 days. The current filing adds to an established pattern of accumulation at this name, though investors should note her prior February 2025 purchases at BX each posted -11.8% returns over 90 days, indicating variable outcomes even within the same security.

Significance 6/10

Director Ruth Porat purchases 295 BX shares in 3 transactions totaling $40,341.53 at blended avg $136.49; stock down 32.7% from 52-week high.

Ruth Porat, a Blackstone director, executed 3 separate open-market purchases on 2025-05-05 totaling 295 shares for $40,341.53, at prices between $135.86 and $137.14, raising her holdings to 8,632 shares. The transactions occur while BX trades at $134.00, down 32.7% from its 52-week high of $199.05 but up 7.2% over the prior 30 days. Her prior trades at Blackstone show mixed outcomes: three February 2025 purchases are down 9.8% at the 30-day mark, while two November 2024 purchases posted gains of 8.5% and 10.5% over 30 days, with subsequent 90-day returns of 3.6% and 5.5% respectively. The cross-ticker track record shows a 100% win rate on 12 prior buys with a 90-day average return of 14.7%, though sell timing on other stocks has been poor (0% well-timed rate). Blackstone's fundamentals remain strong: $3.3B quarterly revenue, $614.9M net income, and 64.9% annual revenue growth, though the P/E of 38.40 reflects elevated valuation. This purchase adds to recent accumulation activity but occurs after recent losses on earlier 2025 BX purchases remain unresolved.

Significance 4/10

Porat (Alphabet CIO) sold 17,690 shares for $3,245,778.16 on 2025-02-21 at blended average $183.48.

Porat executed 6 separate sales totaling 17,690 shares for $3,245,778.16 on 2025-02-21, reducing holdings from 1,466,976 to 1,449,286 shares (a -1.2% reduction). The blended average sale price of $183.48 compares favorably to the current price of $179.66, which is -13.0% from the 52-week high and down -9.4% over 30 days. Porat's cross-ticker track record shows 5 prior open-market sells with an average 90-day return of +30.0% and a 0.00% well-timed rate, meaning the stock rose after each prior sale. This sale follows a pattern where stock price appreciation after the sale has been the norm; near-term downside risk (-9.4% in 30 days) represents an atypical departure from his historical sell outcomes. At Alphabet's current fundamentals—$88.3B revenue, $26.3B net income, and P/E of 18.18—this remains a routine portfolio transaction within a $2,193.8B market-cap enterprise.

Director Ruth Porat buys 375 shares at blended $164.84 amid -17.7% 90-day decline; prior BX trades 100% well-timed at 90-day mark.

Ruth Porat, Blackstone Director, executed 3 separate purchases totaling 375 shares for $61,926.18 on 2025-02-18 at a blended average price of $164.84, bringing her holdings from 8,198 to 8,574 shares. The purchases occurred as BX is -17.7% from its 52-week high and down -9.7% over the prior 30 days, with the current price of $163.90 now below her transaction prices. Notably, her prior 5 trades at Blackstone (all buys executed in August and November 2024) achieved a 100% well-timed win rate at the 90-day mark, with returns ranging from +3.6% to +26.9%, establishing a pattern of purchases that subsequently appreciated. However, stock fundamentals show revenue declined -5.8% year-over-year despite a substantial $780.8M net income, while the company trades at a elevated P/E of 53.21 in a contracting period.

The stock is currently at $176.38, up 18.3% over 30 days and 35.0% over 90 days from the transaction date, extending the director's track record of favorable entry timing.

$34,868
Significance 5/10

Director Porat Ruth purchased 268 shares of BX across 3 transactions for $34.9K at blended average $129.84

Porat Ruth, a director at Blackstone Inc., executed 3 separate open-market purchases totaling 268 shares for $34,868.47 on 2024-08-05, raising her holdings from 8,189 to 8,457 shares. The blended average purchase price of $129.84 sits slightly above the current price of $127.59 and well below the 52-week high of $143.62, placing the transaction in the upper-middle range of recent volatility. Her prior trading at this ticker shows 3 of 5 buy transactions with positive 90-day returns, including two trades in May 2024 that each returned +10.9% to +11.6%, suggesting some pattern of well-timed accumulation at BX specifically. However, the cross-ticker track record shows modest average returns (+4.3% at 30 days, +6.5% at 90 days) with a 46.15% win rate, and her sell timing has been notably poor (0% well-timed rate on 5 prior sales despite +30.0% average 90-day returns, meaning she consistently sold before further gains). The purchase represents a 3.3% increase to her BX position at a price that is already -11.2% from the 52-week high and near recent support, though company fundamentals show -5.8% annual revenue decline and a stretched P/E of 46.06.
