Internet reported that Wall Street's fear index soared on Thursday as investors were shocked by Trump's historic tariff increase. As U.S. stocks and blue-chip stocks such as Apple plunged, the VIX Volatility Index, also known as the "Fear Indicator," surged 30%, heading for its biggest one-day gain since a Fed-driven sell-off in December. "The market thinks it's not just bad economics, it's bad mathematics," said Michael Block, market strategist at 37 Capital. Bullock pointed out that the Trump administration's way of calculating reciprocal tariffs seemed suspicious. "They ignore every rule of classic micro and macroeconomics. This is policy-making equivalent to suicide bombings." Liz Ann Sanders, chief investment strategist at Schwab Financial, said that in the past many investors believed that Trump was just using tariffs as a negotiating tool. "Now the market is saying, wait, this is really happening. We should take his word for it,"Sanders said. "Yesterday, we were not liberated from uncertainty," she said, referring to what Trump called "Liberation Day."
