Round-trip watch Still on the books
Members who disclosed buying TSM and have not disclosed selling, versus their own entry (the most recent disclosed buy). "Open" means no disclosed sale — never "still holds" — and the % is unrealised, on paper. Not investment advice.

Two things to watch per trade: the disclosure lag (how many days passed before the trade was made public) and the price move in that window (how the stock moved during those non-public days). A sell followed by a price drop, or a buy followed by a rise, means well-timed trading — visible here in the open. Note: the Score measures how notable a trade is, not whether it made money — the price move is shown for context and isn't part of it.
