Tech Got Another Lift, But Semis Have Not Cleared the Safety Line
US Stocks · Options · News · Views
Monday's U.S. close was not weak. SPY finished at 751.28 versus a prior close of 744.78. QQQ closed at 722.82 versus 712.60, with mega-cap tech pulling the index higher again. DIA and IWM also rose, so this was not just one or two giants holding up the tape.
Still, the candle should not be overtrusted. During the Asian session, QQQ slipped back toward 717, SOXX fell from 581.51 toward 569, and SMH moved from 604.30 toward the 594 area. The risk appetite during regular trading was real. The selling pressure in semiconductors was real too.
That is the main setup today: the index can still be supported by large-cap weights, but the AI chain has not fully escaped the high-volatility zone. Chasing is easy. The harder part is sitting through the overnight session when the highest-beta part of the market gets hit first.
SOXX closed Monday at 581.51, almost back to the upper end of the 554 to 582 range. SMH closed at 604.30 after touching 618.21 intraday. This is the important area. If 582 holds, the market can go back to talking about AI capex and compute supply. If it fails, the rally was just an oversold bounce.
Among single names, NVDA closed at 195.55. The gain was modest, but the stock held up. AMD saw a much larger move as investors traded the possibility that Nvidia's next-generation AI rack system could be delayed. If the leader's delivery schedule slows even a little, AMD, Google's custom silicon, and other compute suppliers get a wider window.
That is also the problem. Semis are no longer trading only on story. They are trading on supply-chain timing and valuation support. MU closed at 984.75 during the regular session, then moved back near 946 overnight. MRVL closed at 249.27 and slipped toward 241.50 overnight. Memory and high-speed interconnect names have the most torque. They rise fast and give it back fast. The real risk here is not a small pullback. It is volatility forcing late buyers out.
TSLA closed Monday at 419.77, up from 393.45, after touching 420 intraday. The Robotaxi expansion into a small area west of Miami added fuel to the autonomy narrative. A low-open, high-close day like that helps high-beta sentiment.
But TSLA should not be treated as a clean trend stock yet. The 420 area was already a prior pressure zone. After delivery numbers landed, the stock had already gone through one round of expectation unwind. This Robotaxi expansion is incremental, but the area is still small. It validates the story more than it immediately revalues the revenue model.
For trading, TSLA is more useful as a risk-appetite thermometer. If 405 to 410 holds, short-term money is still willing to stay in high beta. If it falls back below 400, this becomes another failed swing into resistance. A real medium-term reset needs expansion speed, regulatory feedback, and operating data to line up.
ASML closed Monday at 1825.07 and traded strongly. SK Hynix's plan to spend 11.9 trillion won on EUV lithography tools, while also moving ahead with a U.S. listing plan, shifted attention from who sells GPUs to who can keep expanding capacity. If HBM and advanced-node capacity remain tight, equipment and memory stay central to the AI trade.
That also explains why ASML, ARM, QCOM, and DELL were all on high-volatility screens. Capital is not only buying one chip designer. It is repricing the entire AI infrastructure chain: compute chips, memory, equipment, servers, networking, power, and cloud. The longer the chain, the more opportunities there are. It also creates more noise.
I would separate the pieces. Strength in equipment says capex is not over. But the overnight pullback in MU says investors are not willing to give every AI-linked company a free valuation pass. The next test is simple: do orders keep moving higher, and does volume support the stocks when they pull back?
The main line is still semiconductors. SOXX moved back to 581 during the regular session, then slipped to 569 overnight. That means the 582 area has not been fully reclaimed. If semis recover 582 again, the rebound can continue. If they lose 554, treat it as a failed bounce and watch 532 first, then the 489 to 500 area.
QQQ has a steadier structure than SOXX, which means mega-cap tech is still protecting the index. META closed at 600.29, AAPL at 312.66, GOOGL at 366.46, and AMZN at 244.16. Those weights are not breaking down. As long as they hold, the index will not look too bad. But if semis keep fading, tech internals will keep splitting.
For the next couple of sessions, there is no need to fill the book all at once. Let strong names pull back and hold. Do not chase weak names just because they bounced for one day. AI is still the main line, but the job now is not to prove the story is alive. It is to confirm that price is still willing to pay for it.
