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 $1.5 million 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 (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, 17.7% above the latest close of $412.61; a close below $272.25 would be a new 52-week low, 34.0% below it.
• Growth: revenue rose 36.4% year over year in the quarter ending Sep 2026 (trend: accelerating). At a P/E of 4.7, 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.

How TSM compares with its peers

Over the past month TSM ranks 3 of 6 in this group (-4.1%); the best was NVDA (-2.4%) and the weakest INTC (-17.4%).

TSM's P/E of 4.7 is below the peers' median of 34.5, so investors pay less for each dollar of its profit.

A dash in the P/E column means the company lost money over the last 12 months, so it has no P/E.

Since 2023, TSM fell 10% or more in a month 5 times (separate episodes, not counting the current one). Three months later it was higher in 3 of 4 cases; the median change was +29.6%.

Key terms on this page

P/E ratio

Price-to-sales

Market value divided by the last 12 months of revenue. Useful for companies with little or no profit, but it ignores margins.

Form 4

The SEC form a company's officers, directors and 10% owners must file within two business days of buying or selling its stock.

Open-market trade

A purchase or sale on the exchange at the market price, paid with the insider's own money (code P or S on Form 4), as opposed to option exercises, grants or gifts.

Form 13F

A quarterly SEC report listing the U.S. stock holdings of every investment manager with more than $100 million. It is due 45 days after each quarter ends, so it shows positions with a delay.

52-week high / low

The highest and lowest daily closing price over the past year (about 252 trading days).
