- Every member of the group fell, with Tesla dropping 14% and Alphabet falling over 7%

The Magnificent Seven stocks had their worst day since April 2025 on July 23, wiping out close to $900 billion in combined market value. Every member of the group fell, with Tesla and Alphabet leading the losses.
Tesla dropped around 14% after its quarterly results, shedding roughly $200 billion in market value alone. Alphabet fell over 7%, also following its earnings report.
The Roundhill Magnificent Seven ETF fell more than 4% on the day, reflecting the broad sell-off across the group.
Alphabet posted strong revenue and reported a backlog in its cloud services division. But investors reacted badly to the company’s rising capital expenditure on artificial intelligence infrastructure.
Evercore ISI senior managing director Mark Mahaney explained the shift in investor thinking. He said people would rather put money into the companies receiving AI investment dollars than those spending them.
Why Investors Sold Alphabet
Alphabet’s spending plans highlighted a divide forming in the AI trade. Investors are pulling back from the companies building AI infrastructure and moving toward those supplying the parts.
Memory chip makers benefited from this rotation. Shares of Micron, SK Hynix, and Sandisk all rose on the day as investors saw them as direct winners from rising AI spending.
Tesla also flagged heavy spending on artificial intelligence. The company is pushing further into autonomous robotaxis and robotics, though both remain in early stages.
What Analysts Are Saying
Brent Schutte, chief investment officer at Northwestern Mutual Wealth Management, told Yahoo Finance that investors should look at diversifying into less expensive stocks.
He said investors should focus on companies with real earnings today, not those relying on future outcomes that may or may not happen. He pointed to Tesla as an example of a stock where future promises have long driven the price.
The sell-off follows a period of strong performance for most Magnificent Seven members. The group had broadly recovered from the tariff-driven market turbulence seen in April 2025.
That April drop was previously the worst single-day decline for the group. Thursday’s session now matches or exceeds it in scale.
Amazon, Apple, Meta, Microsoft, and Nvidia all fell alongside Tesla and Alphabet, though their losses were smaller.
Nvidia dropped around 1.5% and Microsoft fell about 2%. The declines were broad but uneven, with Tesla and Alphabet absorbing the heaviest hits.
The day’s losses reflect how sensitive large-cap tech stocks remain to earnings results and forward spending guidance, particularly when it comes to AI.
