ASML and TSMC Beat Earnings — So Why Did Both Stocks Drop 8%?

Something unusual is happening this earnings season: strong results are no longer enough. ASML Holding (NASDAQ: ASML) and Taiwan Semiconductor Manufacturing (NYSE: TSM) both beat expectations in their most recent quarters and raised their full-year outlooks — yet both stocks dropped hard. ASML fell roughly 8% the day after reporting, while TSMC slid about 4%. Samsung Electronics delivered a colossal 15-fold surge in operating profit and still got punished with an 8% decline. If great earnings can’t lift these stocks, what will?

The answer lies in what Wall Street is really worried about. These chip and equipment giants are what technology analyst Tiernan Ray calls ‘capex takers’ — they build infrastructure based on spending decisions made months or even years ago by the big hyperscalers (Google, Microsoft, Meta, Amazon). Their current numbers are locked in. But what investors are now pricing in is forward uncertainty: Will Amazon still be writing monster AI infrastructure checks in 2027? Will Meta’s data center buildout slow down? The companies reporting right now — ASML, TSMC, Samsung — structurally cannot answer those questions. Only the hyperscalers can. That’s exactly why earnings from Google (reporting imminently), Microsoft, Meta, and Amazon (all due by July 30) matter so much for chip stocks. The iShares Semiconductor ETF (SOXX) briefly fell into bear market territory — down over 20% from its peak — as a reflection of this uncertainty, not a sign that AI demand is actually collapsing.

  • For retail investors, this creates a potential opportunity. If the hyperscalers confirm continued heavy AI infrastructure spending in their Q2 reports — which many analysts expect — a sharp recovery rally in AI chip stocks and equipment names could follow quickly. ASML is a near-monopoly supplier of extreme ultraviolet lithography machines that are essential for manufacturing leading-edge chips. TSMC makes chips for Apple, Nvidia, AMD, and virtually every other major semiconductor company. These are not distressed businesses — they’re elite franchises temporarily caught in a sentiment vacuum. Watch Google’s report this week closely, then Microsoft and Meta on July 29, and Amazon on July 30. Strong AI capex guidance from any of these four could trigger a rapid reversal in beaten-down semiconductor names. Investors comfortable with volatility may find this window worth watching closely.
