Wall Street on Friday suffered its biggest weekly retreat since the peak of the COVID-19 pandemic collapse in 2020. The panic was sparked by U.S. President Donald Trump's sweeping reciprocal tariffs announcement.

Wall Street's "fear gauge" is back at pandemic-era levels, reflecting escalating unease about the market fallout from President Trump's tariff blitz. The Cboe Volatility Index, or VIX, jumped, recently standing at about 44.

"The economic pain that will be brought by these tariffs are hard to describe and can essentially take the US tech industry back a decade," Dan Ives said.

Investors are looking for signs the selling in the U.S. stock market may have reached a crescendo, but say that the check marks are not yet all ticked and there is room for further pain.

The S&P 500 fell almost 5 percent on Thursday, its worst drop since June 2020, as allies and adversaries alike criticized President Trump’s action and weighed their responses.
