The Week in the Indices

The Nasdaq 100 bore the brunt of this week’s selling, dropping 4.16% to 695.3 as semiconductor stocks officially entered bear market territory — down more than 20% from their late-June record. The S&P 500 fell 1.54% to 743.3, dragged lower by its heaviest tech weighting in decades. The Dow held up relatively better at -0.95% (520.8), and the Russell 2000 lost just 0.66% to 294 — a clear sign that the damage was concentrated in mega-cap tech, not broad risk appetite.

The VIX surged 24.88% to 18.77. That’s not panic territory (sub-20), but it’s a sharp repricing from the complacency that defined June. The move signals hedging demand is rising, particularly around large-cap tech positioning, and options markets are starting to price in the possibility that the chip selloff has further to run.

Sector Winners & Losers

Energy (XLE) led all sectors by a wide margin, rallying 4.72% to $57.68 as oil-linked names caught a bid from the crude spike. Financials (XLF) posted the only other green week at +0.99% ($56.26), supported by strong Q2 results from BlackRock and bank earnings broadly coming in ahead of expectations.

Technology (XLK) was the week’s clear laggard, falling 5.48% to $175.6. The semiconductor complex — Micron, AMD, Intel, Marvell — all took heavy losses as investors questioned the sustainability of AI capital expenditure. Industrials (XLI, -1.38%) and Consumer Discretionary (XLY, -1.54%) also declined, while Healthcare (XLV, +0.16%) and Materials (XLB, -0.71%) were effectively flat. The rotation story is straightforward: capital is leaving the AI trade and moving into old-economy cash flow — energy producers and banks.

Rates, Commodities & the Dollar

The 10-year Treasury yield slipped to 4.541% (-0.61% on the week) and the 30-year edged down to 5.064% (-0.14%). Yields drifting lower while equities sell off points to a mild flight-to-quality bid, though the move was contained — this isn’t a growth scare, it’s a sector repricing.

WTI crude was the week’s standout, surging 14.51% to $81.77 as the U.S. naval blockade of Iran choked tanker traffic through the Strait of Hormuz. Gold slipped 1.98% to $4,023 and silver fell 6.00% to $56.22 — precious metals gave ground as the dollar held steady and real rates stayed elevated. Copper edged up 0.59% to $6.271, a modest positive for the growth outlook. The DXY was essentially flat at 100.8 (-0.21%), with EUR/USD at 1.145 and cable firming to 1.345.

What Drove the Week

Three forces shaped the tape. First, the semiconductor bear market accelerated — the Philadelphia Semiconductor Index has now lost roughly $1.5 trillion in market value since its June 25 peak, with ARM, Marvell, and Intel each down more than 30% over that span. Oracle hit a 52-week low on AI spending fears. The market is reassessing how much of the AI capex cycle is already priced in.

Second, U.S.–Iran tensions escalated sharply. The U.S. military conducted a third consecutive night of strikes, and the Strait of Hormuz disruption sent crude ripping higher, repricing the entire energy complex in a single week.

Third, earnings season delivered mixed signals. IBM warned on Q2 results, blaming a shift from software to hardware spending — shares dropped 18%. Netflix fell more than 10% Friday after revenue narrowly missed consensus. On the positive side, BlackRock beat and bank earnings broadly held up, giving financials a bid.

Week Ahead

The bias tilts defensive heading into next week. With chip stocks in a confirmed bear market and oil above $80, the risk is that the tech-to-energy rotation accelerates further. The level to watch is Nasdaq 100 at 695 — a clean break below opens room toward the 200-day moving average and would likely pull the S&P 500 with it. The biggest catalyst on the calendar is the next round of mega-cap tech earnings, which will either stabilize the AI narrative or confirm the repricing. We’ll be tracking the key levels and sector rotations at Luna3.
