TSMC and Micron recently delivered powerful operating results, yet semiconductor shares continued to weaken.
That disconnect matters more than another headline beat. It suggests investors are looking beyond current demand and asking whether today’s AI spending boom can keep producing attractive returns.
This week brings a broader test. Alphabet is the main event, while Vicor, Texas Instruments, ServiceNow, IBM and Intel provide different views of the same investment cycle. Tesla adds another high-valuation test, although its immediate debate is margins and cash flow rather than the health of semiconductors.
Why Alphabet matters most
Alphabet sits at the centre of the AI trade. It is both a major buyer of computing infrastructure and one of the companies expected to turn that investment into revenue through Google Cloud, Search, advertising and enterprise AI services.
That makes its report more important to the wider market than Intel’s. A strong update on cloud growth, AI monetisation and capital efficiency could support sentiment across data-centre suppliers.
Weak guidance, slowing margins or another jump in spending without a matching revenue payoff would reinforce the concern that the AI build-out is becoming more expensive faster than it becomes profitable.
The chart reflects that uncertainty.
Alphabet has rejected the 373.52–378.56 neckline area and fallen back into the 337.47–349.00 support zone around February’s highs.
Price is also testing the lower edge of its daily 50-period band and a longer-term logarithmic trendline.
