Trump is back talking tariffs, saying they boosted growth and investment, but the facts aren’t really backing that up. Data shows the U.S. economy wasn’t weak before tariffs, and a lot of economists say the real impact has been higher costs and more uncertainty, not some massive boom. Why this matters for markets is simple. Tariffs mess with supply chains, push prices up, and hit margins. That pressure eventually shows up in $AAPL, $TSLA, $GM, industrials, and even retailers when costs get passed down. Investors hate uncertainty, and trade policy noise is pure uncertainty. Bottom line: tariffs can sound tough, but Wall Street mostly sees them as a volatility trigger. If this ramps up again, expect more chop in stocks tied to global trade. Stay nimble and don’t ignore the policy risk baked into prices.
