If Taiwan Semiconductor Manufacturing was on your watchlist instead of in your portfolio over the last year, the gap in outcome may feel sharp. For Taiwan Semiconductor Manufacturing shareholders, the return over the past year was 66.4%, including dividends. That move now sits alongside record Q3 2026 profitability and fresh plans for heavier US expansion, inviting a tougher question. If analysts already flagged margin dilution risks from overseas fabs in late 2025, what business assumption about AI demand and pricing power would have justified owning the stock anyway?

The Two Stories Taiwan Semiconductor Manufacturing Investors Were Arguing About
The shares cost NT$1,465 at the start of the period, and you had to decide which story about Taiwan Semiconductor Manufacturing felt closer to reality.
On the bullish side, one camp saw a Fair Value of NT$1,800, a price implied by assumptions of strong AI demand and higher margins. This view was backed by expectations that advanced packaging capacity and U.S. fabs would support sustained pricing power.
The bearish view anchored Fair Value at NT$1,100. This was based on the idea that overseas expansion and rising capital and regulatory costs would steadily erode profitability through ongoing margin dilution and customer concentration risk.
What The Results Changed For Taiwan Semiconductor Manufacturing
Record Q3 2026 numbers from Taiwan Semiconductor Manufacturing, with revenue at NT$1.49t and net income at NT$763.1b, backed the bullish story that AI demand and advanced nodes could support stronger profitability. Net margin moved from 45.7% in Q3 2025 to 51.1%, although later commentary about rising AI spending concerns and Chinese competition kept the bearish worries about durability alive. Overall, the evidence cut both ways.
The episode turned on one testable claim: that AI driven demand would support higher margins despite overseas expansion costs. For any other chip manufacturer, you would track net margin and capacity guidance together to see whether pricing and mix really offset higher investment and regulatory spending.
What Taiwan Semiconductor Manufacturing’s Price Already Assumes
Taiwan Semiconductor Manufacturing now trades at NT$2,350, after a 66.4% gain over the past year. The current Narrative’s Fair Value sits above that level, and according to steingar, an investor in the Simply Wall St Community who wrote the Narrative, the market still prices the group too much like a cyclical foundry.
