What would change the picture for TSM

These are the specific events and levels to watch. None of them is a prediction.

• Insider buying: 30 insiders bought $761,912 in 90 days. More purchases would strengthen that signal. Sales by the same people would weaken it.
• Analyst ratings: the average score moved from 4.21 to 4.23 over three months. That is on a scale where 5 is strong buy and 1 is strong sell. A run of downgrades after earnings usually shows up here first.
• Price levels: a close above $485.8 would be a new 52-week high, 22.8% above the latest close of $395.75. A close below $272.25 would be a new 52-week low, 31.2% below it.
• Growth: revenue rose 36.4% year over year in the quarter ending Sep 2026. The trend is accelerating. At a P/E of 4.5, a slowdown would matter more than at a lower multiple.
• New shares: dilution risk is low now. A new shelf registration (S-3) or a prospectus supplement (424B) for an offering would raise it.
