Stocks Tumble as Chipmakers Plunge, Oil Spikes
US MBA mortgage applications fell -6.4% in the week ended July 24, with the purchase mortgage sub-index down -3.6% and the refinancing mortgage sub-index down -9.9%. The average 30-year fixed rate mortgage rose +7 bp to an 11.5-month high of 6.76% from 6.69% the prior week. The outlook for strong Q2 earnings, which continue this week, is a bullish factor for stocks.
How this was made
The 30-second read
Why it matters
Traders are likely to reprice rate expectations around the FOMC and adjust exposure to AI infrastructure and semis, while rotating toward energy beneficiaries of higher crude. Company-specific earnings reactions (sales/EPS misses and guidance raises) add idiosyncratic volatility.
Market read
This is a cross-asset risk repricing day: oil-driven hawkishness pressures rates and tech/semis, while earnings season and specific prints drive large single-name moves.
What to watch
The piece emphasizes oil and FOMC probabilities but does not quantify how much of each company’s move is earnings-specific versus sector beta, which can distort single-name trade sizing.
Background
The article ties today’s broad stock weakness to a semiconductor selloff and rising crude oil, while noting a heavy megacap earnings calendar and ongoing Q2 earnings beats.
Ticker impact
The article flags Microsoft as one of the megacap tech earnings due today, shaping near-term AI-spending expectations and risk sentiment.

Nebius Group NV is cited as down more than 9% to lead Nasdaq 100 losers, making it a same-day momentum risk.
Near-term downside pressure likely to persist while the broader chip/AI complex remains sold.

KLA Corp is down more than 7% as chipmakers plunge, linking its tape action to the semiconductor selloff.
Likely underperformance versus broader market while SOX remains pressured.
No KLA-specific news is provided, only that it is down with the group.

Near-term downside bias while the semiconductor index is at a 2.5-month low.

Market effects
Oil up more than 7% is framed as hawkish for Fed policy, pressuring rates-sensitive tech and supporting energy producers and service providers.
Overseas markets are mixed, with Euro Stoxx 50 down and Japan’s Nikkei down, reinforcing a cautious global tape.
Higher crude and hawkish rate expectations can transmit to global tech multiples and semiconductor demand expectations via capex and inflation channels.
Counterpoint
The selloff in chipmakers may be more about positioning and rates sensitivity than a fundamental AI demand break, given the article’s note that most S&P 500 companies are beating Q2 estimates.
