TSMC reported first quarter earnings on Thursday, posting a 58 percent year over year jump in net income and raising full year capex guidance. Under almost any reading, those were strong results. Yet the semiconductor index traded flat on the news, and a group of megacap semiconductor names including Nvidia, AMD, and Broadcom finished the day lower. When a sector prints strong numbers and the stocks do not respond, that is usually the market signaling something. Fund flow data and positioning surveys this week suggest the semiconductor rally is in a pause phase, and investors are starting to reposition.
Through the first quarter, the Philadelphia Semiconductor Index posted a modest gain, the smallest quarterly advance since early 2023. Nvidia specifically finished the quarter up 6 percent, a meaningful deceleration from the triple-digit gains it posted in 2023 and the 40-plus percent returns of 2024. The price action reflects a simple arithmetic reality. At current earnings multiples, the rate of earnings growth has to stay extraordinary to justify further multiple expansion. Earnings are still growing. They are just not growing quite as far ahead of consensus as they were.
Fund flow data from EPFR Global shows that semiconductor-focused ETFs saw modest net outflows in the last three weeks of March and the first week of April, the first stretch of sustained outflows for the category since mid-2022. Flows into broad technology ETFs remain positive. Flows into the specifically semiconductor-tilted products are turning. That kind of divergence often appears early in a sector rotation, before the price action fully confirms the shift.
Several fundamental factors are behind the pause. Hyperscaler capex guidance has been strong but not raised further from the levels set at the start of the year. Microsoft, Google, Meta, and Amazon are collectively spending somewhere around $340 billion on capex in 2026, most of it on AI infrastructure. That is a lot of money. It is not, however, a materially larger number than what the market had already priced in three months ago. The incremental upside surprise has faded even though the absolute level remains high.
On the supply side, capacity is catching up in a way that matters. TSMC is ahead of schedule on its advanced node ramp. Samsung is reporting improved yields on its 2-nanometer process. Intel's foundry strategy has produced a couple of concrete customer wins. The supply shortages that priced chips at premium levels through much of 2023 and 2024 are easing in most categories. The areas of genuine scarcity, like the highest-end memory for AI accelerators, are narrowing. Pricing power across the semiconductor complex is returning to more normal levels.
The rotation that is beginning to show up is out of the megacap semiconductor names and into a set of adjacent beneficiaries. Data center power and cooling companies have outperformed the SMH index year to date. Electrical infrastructure names like Eaton and Vertiv continue to post strong numbers. Industrial REITs with AI-adjacent exposure have started to see inflows. Equipment makers that provide services and parts to the foundries are holding up better than the chip designers. Investors who believe in the AI buildout are increasingly expressing that belief through picks that are not as richly valued as the headline semiconductor names.
Some of the pause is about position sizing. Megacap tech now represents roughly 31 percent of the S&P 500 by market cap, a concentration near the all-time high. Any institutional investor benchmarked against the index who has been overweight semis for the last two years is carrying a large absolute position that produces meaningful drawdowns on any pullback. Risk management frameworks are starting to nudge some of those positions back toward benchmark weight. That flow is not a conviction trade. It is a structural rebalancing that creates real selling pressure regardless of how good the underlying earnings look.
For retail investors trying to interpret the current setup, a few observations are useful. Sector rotations rarely happen in a single quarter and rarely stick on the first attempt. The semiconductor sector has paused and resumed leadership three times since the start of 2023. The question is whether the current pause is a consolidation that sets up the next leg higher or the early innings of a longer period of sideways to lower performance. The answer depends on whether Q2 earnings from the hyperscalers in late July reinforce the capex trajectory or start to suggest it is plateauing.
For long-term investors, the more important question is allocation rather than timing. The semiconductor complex has produced exceptional returns, and portfolios that built up large semi weights over the last three years may be meaningfully overweight relative to target. This is a reasonable time to rebalance, trim concentrated positions to sensible weights, and redeploy into adjacent themes or into diversified benchmarks. That is not a call against semiconductors. It is a discipline that applies to any sector that has had a run this strong.
The semiconductor rally is not over. It is pausing. Strong earnings from TSMC not producing a rally is a clear signal that positioning is full and that the next move will require a genuine positive surprise rather than a confirmation of the existing narrative. Whether that surprise shows up in late July will determine whether this is a pause or a peak.
