Even as markets rally, Trump's policymaking causes angst

As Wall Street puts April's tariff shakeout in the rearview mirror and indexes set record highs, investors remain wary of US President Donald Trump's rapid-fire, sometimes chaotic policymaking process and see the rally as fragile, reports Reuters.

The S&P 500 and Nasdaq composite index advanced past their previous highs into uncharted territory on Friday. Yet traders and investors remain wary of what may lie ahead.

Trump's April 2 reciprocal tariffs on major trading partners roiled global financial markets and put the S&P 500 on the threshold of a bear market designation when it ended down 19 per cent from its February 19 record-high close.

This week's leg up came after a US-brokered ceasefire between Israel and Iran brought an end to a 12-day air battle that had sparked a jump in crude prices and raised worries of higher inflation. But a relief rally started after Trump responded to the initial tariff panic that gripped financial markets by backing away from his most draconian plans.

JP Morgan Chase, in the midyear outlook published on Wednesday by its global research team, said the environment was characterized by "extreme policy uncertainty."

"Nobody wants to end a week with a risk-on tilt to their portfolios," said Art Hogan, market strategist at B. Riley Wealth. "Everyone is aware that just as the market feels more certain and confident, a single wildcard policy announcement could change everything," even if it does not ignite a firestorm of the kind seen in April.
