Asian technology shares came under pressure after concerns about a cooling artificial intelligence trade and weak U.S. earnings, and Taiwan Semiconductor Manufacturing (NYSE:TSM) was pulled into the selloff with a 1.8% decline in Taiwan trading.

The recent pullback adds to a 1 day share price decline of 5.95% and a 30 day share price return of down 14.1%. However, Taiwan Semiconductor Manufacturing still carries a 27.07% year to date share price gain and a 36.29% 1 year total shareholder return, which indicates that longer term momentum remains intact even as short term sentiment cools with the broader AI trade.

The recent swing in Taiwan Semiconductor Manufacturing highlights a simple fork in the road. Are investors reassessing the business itself, or has sentiment just moved faster than the fundamentals? The valuation numbers help frame that tension next.

Most Popular Narrative: 7% Overvalued

Taiwan Semiconductor Manufacturing last closed at $406.13, while the widely followed narrative fair value sits at $378.29. As a result, the shared story in the community treats the recent price as running ahead of that appraisal and anchors everything to a higher required margin of safety.

The time to buy TSMC is not when everyone agrees the AI trade is working and the Taiwan Strait is calm. The time to buy is when a geopolitical scare, an inventory digestion cycle, or a broader market dislocation pushes the stock to a level where you are being adequately compensated for risks that most investors would rather not think about.

See why 135 investors see Taiwan Semiconductor Manufacturing as 7% overvalued.

Result: Fair Value of $378.29 (OVERVALUED)

Still, Taiwan Semiconductor Manufacturing faces real pressure points, including concentrated geopolitical risk around Taiwan and the possibility that rival foundries steadily chip away at its dominance.

Another View: Market Multiples Paint a Different Picture for Taiwan Semiconductor Manufacturing

While the community narrative treats Taiwan Semiconductor Manufacturing as about 7% overvalued versus a US$378.29 fair value anchor, its current P/E of 24.3x tells a different story. That multiple is far lower than both US Semiconductor peers at 41.7x and the wider peer set at 51.4x. It also sits well below a 42.7x fair ratio that the market could shift toward over time.
