Over the past week, rising inflation has intensified concerns that interest rates will remain high for a longer period, combined with adverse factors facing various companies, leading to a significant decline in large tech stocks.

The combined market capitalization of the “Big Seven” U.S. stocks has evaporated by more than $850 billion over the past week.

Meta recorded its worst weekly performance since October 2025, with a decline of over 11% during the week. Earlier this week, the company lost a landmark social media lawsuit, and Wall Street has been reacting to this ongoing situation.

The jury ruled that Meta was negligent and failed to protect underage users on its platform, alongside Google’s parent company, Alphabet (GOOG, GOOGL). Alphabet’s stock fell nearly 9% during the week.

Microsoft (MSFT) dropped 6.5% during the week and may be facing its worst quarterly performance since 2008, with software stocks being particularly hard-hit.

NVIDIA (NVDA) and Amazon (AMZN) both experienced declines of about 3% during the week, while Tesla (TSLA) fell nearly 2% over five trading days.

The semiconductor sector rebounded on Friday, but after significant drops on Thursday for SanDisk (SNDK) and Micron Technology (MU), it still closed lower for the week.

Before this sell-off, Alphabet released a new research finding, announcing an algorithm designed to reduce AI memory usage, which caused turbulence in the memory chip and the entire semiconductor sector.

Growth stocks were severely impacted this week due to soaring oil prices raising inflation expectations and rising bond yields. Investors believe that the Federal Reserve will not be able to cut interest rates as previously expected this year.

The only stock among the “Big Seven” to see a slight increase during the week was Apple (AAPL). Reports this week indicated that Apple plans to open its Siri voice assistant to competing AI services beyond OpenAI’s ChatGPT.
