The top six tech companies have lost $1.8 billion due to Trump’s tariffs.

US technology stocks are starting the week with high volatility as President Donald Trump stood firm on his global tariff plans.

The six most prominent stocks in this sector—Nvidia, Apple, Meta, Amazon, Microsoft, and Alphabet—fell after a brief rally amid a brief attempt at a broader market recovery.

Companies are coming off a tough week, losing more than $1.8 billion in market value during two days of liquidation; the Nasdaq Composite also recorded its worst week since the start of the pandemic and entered a bear market.

Trump stood firm on his aggressive tariff plans around the world over the weekend, with an initial 10% unilateral tariff going into effect on Saturday. Wall Street was hoping for progress in negotiations between the administration and other countries or news of a possible delay in the reciprocal tariffs scheduled for April 9.

Other technology stocks that also felt the impact last week were Oracle and Palantir Technologies, which fell more than 2%.
