Assessing TSMC (NYSE:TSM) Valuation as Shares Continue Steady Upward Momentum

Kshitija Bhandaru

Taiwan Semiconductor Manufacturing (NYSE:TSM) has caught plenty of investor attention lately, not because of a game-changing AI deal or product release, but simply because its stock continues to march higher. Moves like this naturally make shareholders and would-be buyers wonder if something is quietly brewing under the surface or if the company’s long-term growth story is just that compelling. Either way, this kind of upward momentum is tough to ignore, and it brings big questions for anyone considering what to do with TSM shares now.

So what’s driving this? In the past month alone, Taiwan Semiconductor Manufacturing has notched a gain of just over 2%, and the picture gets even brighter if you step back a bit: the stock is up 16% over the past 3 months and more than 53% over the past year. These moves haven’t come on the back of flashy news, but rather seem tied to steady revenue and net income growth, and a strong three- and five-year track record that would be the envy of many established tech giants. It is the kind of climb that hints at building momentum in investor sentiment, even as no single headline is doing the heavy lifting.

Given all this, the big question is whether Taiwan Semiconductor Manufacturing is now trading at a premium with all that growth already priced in, or if there is still room for investors to capture more upside from here.
