TSMC in focus as AI earnings and US CPI collide this week

Wall Street's Q3 earnings season gets properly under way this week, with the major banks set to release their quarterly figures from tomorrow. That will draw plenty of attention in equities, yet the AI theme remains one of the most-watched narratives. Given that, TSMC stands out as the earnings release I'd single out for the coming days.

The key uncertainty investors are wrestling with over the AI boom is whether the heavy outlays on chips and data centres can be sustained.

TSMC's report on Thursday, 15 October, may shed more light on that. The company is among the world's largest chipmakers and sits at the heart of the AI supply chain. Nvidia may be the more recognisable name, designing the powerful processors that AI applications depend on, but someone has to build them — and that is TSMC's role.

For its US-listed shares, analysts forecast EPS of around $4.42, with net profit expected to jump roughly 65% to NT$746.3 billion.

TSMC has already put together a strong stretch. It posted record revenue of NT$1.49 trillion ($46.7 billion), up 50% year on year and ahead of the NT$1.46 trillion market forecast. But with expectations elevated, topping that would be a demanding task, and investors may want more than merely another record to be pleased.

So the focus will be on whether TSMC can sustain that momentum into 2027. What management says about AI chip demand and whether clients are still increasing orders could carry more weight than the headline numbers.

Before TSMC's results land, the broader market backdrop also matters.

Wednesday's US CPI release is arguably the week's bigger risk event for markets. With Treasury yields already high, another hotter-than-expected inflation figure could add pressure on tech stocks, no matter how TSMC performs.

With that in mind, a positive outlook from TSMC might give some reassurance that the AI boom still has room to expand. Whether that will be enough to keep AI shares climbing is a separate matter.

Investors are already paying a rich price for AI-linked stocks. If inflation concerns and climbing bond yields keep weighing on sentiment, appetite for those valuations could quickly fade.
