Big Tech stocks took a hit Thursday, dragging the Nasdaq Composite down 1.2%, but the semiconductor sector moved in the opposite direction after upbeat news from Micron and Qualcomm. The split reflects a market grappling with two competing forces: the promise of AI-driven earnings growth versus the threat of higher interest rates.
What happened?
The Nasdaq fell as Apple dropped 4.8% and other mega-cap tech stocks slid. Meanwhile, the Philadelphia SE Semiconductor Index stayed in positive territory. Micron Technology surged 10% as investors raised expectations for memory chip demand tied to AI servers. Qualcomm also gained after lifting its long-term data-center revenue targets.
The divergence wasn't random. Markets were trying to weigh stronger AI data-center demand against the possibility that interest rates will stay higher for longer. An inflation reading that matched forecasts did little to calm nerves, and traders leaned toward at least one Federal Reserve rate hike by year-end after new Fed Chair Kevin Warsh's comments about inflation.
Why the split?
Higher expected interest rates raise the "discount rate" investors use to value future profits. That hits expensive mega-cap and software stocks hardest, since more of their value depends on profits far in the future. Chipmakers, by contrast, can hold up better when their near-term earnings story is improving.
"Tech" is starting to trade less like one big block and more like a set of mini-stories: rates-sensitive multiples on one side, and earnings upgrades on the other. Semiconductors can still outperform if analysts are revising profit forecasts up fast enough to offset the higher-rate headwind.
This dynamic is similar to what we've seen in other sectors. For example, energy stocks have also shown internal splits, with oil and gas moving differently based on their own supply-demand stories.
What it means for investors
For everyday investors, the key takeaway is that tech indexes are no longer a monolith. A Nasdaq drop can mask a semiconductor rally when rate expectations shift. The day-to-day direction is increasingly driven by which companies are getting near-term earnings upgrades versus which are mainly trading on valuation multiples.
When investors start penciling in another rate hike, it compresses valuations most where prices rely heavily on profits far in the future. That helps explain why Apple fell 4.8% and other mega-caps slid even as parts of the chip sector rose. The takeaway is bigger performance gaps within tech indexes.
This also connects to broader market trends. For instance, Latin American stocks and currencies rallied as the US dollar weakened, showing how global markets are reacting to shifting rate expectations. Similarly, India stocks extended their winning streak as falling oil and central bank policy eased pressure.
What to watch next
Investors will be watching for more earnings reports from chipmakers and mega-cap tech companies to see if the divergence continues. The key question is whether earnings upgrades can keep pace with the headwind from higher rates. If inflation remains sticky and the Fed signals more hikes, mega-cap stocks could face further pressure. But if AI demand continues to drive strong earnings growth for chipmakers, they may continue to buck the broader tech trend.
Another factor to watch is the impact of rising memory chip costs on consumer electronics. Apple may raise Mac and iPad prices as memory chip costs surge, which could further pressure its stock if consumers push back. Meanwhile, Apple has already hiked iPad and Mac prices as AI demand drives up memory chip costs, adding to the complex picture for tech investors.
