Schwab Market Perspective: The Tariff Effect

Stocks have surged since the White House backed away from sweeping tariffs imposed in early April, although U.S. tariff policy remains uncertain and is a potential driver of continued volatility. Higher tariffs could slow economic growth while raising inflation—which is still above the Federal Reserve's 2% target rate—complicating the Fed's move toward cutting interest rates. Meanwhile, emerging-market stocks have outperformed U.S. stocks so far this year, similar to their performance during 2017, the first year of President Donald Trump's first term.

U.S. stocks and economy: Stocks rebound

Stocks jumped on May 12th after the White House announced a 90-day reduction in U.S.-China tariffs. But even before that, the S&P 500 index had surged 13.7% between April 8th and May 8th, the biggest one-month gain since 2020, as stocks recovered from a steep plunge (into or near bear-market territory, depending on the index) after Trump announced stiff tariffs on dozens of countries.

That swift plunge was enough to send many investor sentiment metrics into "extreme pessimism" territory. As is typically the case when that happens—at extremes, investor sentiment tends to be a contrary indicator—it created fertile ground for a positive catalyst to help jolt stocks into the opposite direction. The question now is whether the market plunge we experienced was more of a pandemic-like dip and recovery, or the start of a longer, protracted bear market.

We follow both attitudinal and behavioral measures of investor sentiment. The former tracks how investors feel—or what they're saying—about the market, whereas the latter tracks what investors are doing with their money. At times, there are major differences between both, and at crucial turning points in cycles, the difference has important implications for future returns.

Arguably, the most popular attitudinal metric is the weekly Investor Sentiment Survey published by the American Association of Individual Investors (AAII), which asks investors whether they are bullish (expecting stock prices to rise), bearish (expecting stock prices to fall) or neutral looking out over the next six months. The spread between the share of bulls and bears collapsed swiftly in April (meaning bears outnumbered bulls) to a level consistent with the lows seen toward the end of the bear market in 2022.
