Nvidia’s stock plunge leads ‘Magnificent Seven’ to a record weekly market-cap loss

The decline in “Magnificent Seven” stocks erased a collective $950 billion from their market capitalizations this week, which made for the group’s worst-ever weekly loss of market value.

While Tesla Inc.’s stock TSLA was the biggest weekly percentage decliner of the gang from a stock perspective, Apple Inc. AAPL, Microsoft Corp. MSFT and Nvidia Corp. NVDA were bigger contributors to the market-cap losses, as those latter three companies are all worth substantially more than the electric-car maker.
