@ $38.90
Significance 4/10

Kim Tony purchases 23,645 shares at $38.90 for $919,754.50, raising stake 42.0%; timing pattern shows 0 of 2 prior BST buys well-timed at 90 days.

Kim Tony made 2 separate purchases totaling 23,645 shares for $919,754.50 at a blended average price of $38.90 on 2026-02-05, increasing holdings by 42.0% to 79,959 shares. The current price of $40.50 stands 8.1% below the 52-week high, within normal volatility. However, his prior trades at BlackRock Science & Technology Trust (BST) show a concerning pattern: both a buy on 2025-02-20 (30d return -11.2%, 90d return -8.7%) and a buy on 2025-02-14 (30d return -12.2%, 90d return -6.5%) failed to deliver positive 90-day returns, with a 0% well-timed rate at this ticker. His cross-ticker track record across 6 prior buys reveals similar headwinds, with an average 90-day return of -2.9% and a 90d win rate of 33.33%. This filing warrants attention given the large dollar commitment relative to a pattern of previously unfavorable entry points.

@ $40.70
Significance 4/10

Kim Tony bought 16,000 BST shares at $40.70 (Jan 23, 2026); holdings +38.5% but prior buys at this ticker underperformed.

Kim Tony purchased 16,000 shares of BlackRock Science & Technology Trust (BST) at $40.70, raising his holdings by 38.5% to 57,514 shares. This represents the insider's third accumulation at BST within the past year. However, prior trade outcomes at this ticker are notable: two previous buys in February 2025 produced 90-day returns of -8.7% and -6.5% respectively, with neither transaction resulting in positive returns within 90 days. The insider's cross-ticker track record shows an avg 90d return of -2.9% with a 33.33% win rate across 3 prior buys. BST currently trades at $41.03, -6.9% from its 52-week high of $44.07, and is up 2.6% over 30 days but down 5.6% over 90 days. The repeated buying pattern at BST despite prior underperformance suggests continued interest, though the historical performance at this specific holding warrants observation.

@ $38.78
Significance 5/10

Kim Tony purchased 10,264 shares of BlackRock Science & Technology Trust (BST) at $38.78 on 2025-02-20, expanding holdings to 41,514 shares (+32.8%).

Kim Tony completed a substantial open-market purchase of 10,264 shares for $398,037.92, increasing his holdings by 32.8% to 41,514 shares in rapid succession—this buy follows another BST purchase just six days earlier on 2025-02-14. The accumulation occurred near the 52-week high of $38.95, with the current price of $38.03 only 2.4% below that peak, suggesting the timing was not unfavorable relative to recent valuations. The track record shows this insider has made only 1 prior open-market purchase across all tickers, offering limited historical context to assess pattern consistency or accuracy in timing decisions.

@ $38.81
Significance 6/10

Kim Tony purchased 24,000 shares of BST at $38.81 for $931.4K, raising holdings 331.0% to 31.2K shares

Kim Tony acquired 24,000 shares at $38.81 on 2025-02-14, a substantial purchase that increased his position from 7,250 shares to 31.2K shares—a 331.0% expansion of holdings. The transaction occurred near the 52-week high of $38.95, with the stock up 4.0% over the prior 30 days and 6.6% over 90 days. The magnitude of this accumulation—tripling his stake in a single transaction—represents a material commitment to the closed-end fund, though the execution price at the upper boundary of the recent range merits attention as to whether this reflects deliberate purchasing discipline or reactive demand at elevated levels.

Significance 3/10

Director Harris Stayce D. initiates BST position with 30-share purchase at $36.44 on 2024-10-28

Harris Stayce D. purchased 30 shares of BlackRock Science & Technology Trust (BST) at $36.44 on 2024-10-28, establishing a new position following zero prior holdings. The transaction occurred at a price approximately 6.5% below the 52-week high of $38.95, and the stock has gained 4.1% over the prior 30 days. The director's cross-ticker track record includes 20 prior open-market buys, indicating a pattern of opportunistic acquisition activity across multiple securities. The modest position size ($1,093.15 total value) and first-time purchase in BST provide limited insight into conviction levels at this specific holding.
