Semiconductor Momentum Breaks as Inflation and Rates Push Back
US Stocks · Options · News · Views
Today brought a clear rotation in market leadership. Semiconductors and high-momentum AI names sold off sharply. The Philadelphia Semiconductor Index fell more than 6% intraday and closed down about 3%, with 29 of 30 constituents lower and only NVDA finishing green. Healthcare and consumer staples outperformed, suggesting some capital is rotating away from crowded growth trades and toward defensives. This does not confirm that the broader rally is over, but the one-way squeeze higher is beginning to lose momentum.
The macro backdrop also became less supportive. Headline CPI accelerated from 3.3% to 3.8% year over year, while core CPI rose 0.4% month over month and 2.8% year over year. Core services and supercore services inflation remained firm. The 30-year Treasury yield moved above 5%, while the 10-year continued toward 4.5%. Markets are repricing longer-term inflation risk, and persistent energy and services inflation could push the timing of Fed easing further out.
The current rally still depends on two optimistic assumptions: that the Strait of Hormuz does not create another oil shock, and that Big Tech’s AI CapEx begins producing enough revenue and earnings by 2027 to justify today’s spending. Neither assumption has been fully validated. A meaningful part of the recent advance has also been driven by speculative flows and call-option activity rather than fundamentals alone.
Retail call activity is now near or above the extremes seen during the 2021 meme-stock episode. More than 52% of retail opening trades in mega-cap technology are concentrated in calls. Positive gamma is around $21 billion, one-month correlation is below 3%, and realized dispersion is above 64%, all beyond the November 2021 extremes. Extreme positioning does not guarantee an immediate reversal; the 2021 episode persisted for another four to six weeks. But this level of speculation is unlikely to be sustainable indefinitely, so profitable holders should think about risk management before momentum finally turns.
The semiconductor ETFs remain the most important signals. For SOXX, the 489–507 area is the key zone for determining whether the recent squeeze has been broken. Below it, intermediate support sits at 450–467, followed by 368. For SMH, the corresponding decision zone is 533–552, with 499–511 as the next support area. As long as those key zones hold, the sector can still recover; decisive breaks would confirm a more meaningful loss of momentum.
QCOM led the semiconductor decline, falling about 11%. The advance after the breakout above $175 had been driven partly by crowded semiconductor positioning and positive headlines rather than a clear acceleration in fundamentals. Technically, 205–209 is minor support, 190–202 is intermediate support, and 178–183 is deeper support. The stock has not decisively lost 205, so a top is not confirmed, but the long red candle on heavy volume shows that selling pressure has increased materially. At the index level, the main SPY support zones are 728–735, 707–716, 676–695, and 653–672. For QQQ/Nasdaq, watch 688, 645–665, 617–637, and 588–613.
I would not treat one weak session as confirmation of a bear market, but I would also not ignore the extreme positioning signals. The better approach is to manage risk around the key levels. As long as SOXX holds the 489–507 area and SMH holds 533–552, bears have disrupted momentum without fully breaking the trend. A decisive loss of those zones would signal that the short-term squeeze has ended and that the correction needs more time to play out.
For heavily profitable and crowded technology or semiconductor positions, there is little value in trying to sell the exact top. On a pullback toward the first and second support zones, I would evaluate volume, sector breadth, and rates together before deciding whether to trim further or add. The China visit also remains an important catalyst. If it produces real agreements or a meaningful trade framework, that could support exposed sectors. If it ends with little more than meetings and photographs, disappointment itself could become a negative catalyst.
