From the user-provided trading history, TSM is a repeatedly purchased ticker for this member (11 total purchases, 0 sales), with the analyzed purchase occurring after prior TSM buys in 2026-04-09 and 2026-01-08 (both small-range buys in the excerpt) and following larger-position purchases in 2025 (e.g., ranges up to $250,001-$500,000).
