President Donald Trump doesn't like his new nickname 'TACO'. Here's why people are calling Trump TACO and the meaning behind the TACO trade acronym

Tariff Man is back again — and so is Wall Street’s TACO trade. President Donald Trump is once more threatening to lob massive duties on a wide swath of US imports, everything from copper and pharmaceuticals to goods from Japan and Russia.

Markets had dismissed tariff risks under the assumption that Trump would follow an earlier pattern and back off, in what became known as the so-called TACO trade. That allowed stocks to reach new record-high territory recently, marking a stunning rebound from the collapse triggered by his “Liberation Day” reciprocal tariffs in April.
