TSM VP Chuang Tzu-Sou sold 200,000 shares at $69.83 on 2026-05-19; stock now $395.95, up +6.9% in 30 days.
Chuang Tzu-Sou (VP) sold 200,000 shares (200.0K shares) of TAIWAN SEMICONDUCTOR MANUFACTURING CO LTD (TSM) at $69.83, reducing his holdings from 2,695,165 shares (2.70M shares) to 2,495,165 shares (2.50M shares) in the open market. The transaction occurred on 2026-05-19 for a total value of $13,966,000.00 ($14.0M), representing a -7.4% reduction of his pre-transaction stake. Notably, this sale followed his prior buy on 2026-04-09 at the same ticker, which achieved strong 30-day and 90-day returns (+611.4% and +584.2% respectively)—a well-timed entry in his same-ticker history. Since the May sale, TSM has appreciated +6.9% over 30 days and +8.7% over 90 days, meaning the insider sold before a subsequent rally. This outcome differs from his demonstrated cross-ticker track record (100% 90-day win rate on 1 prior buy), suggesting either a tactical position reduction rather than a conviction-driven exit, or market conditions at the time of sale that warranted the reduction despite subsequent upward price action.
