Investors are not getting too carried away with late Wednesday's court ruling striking down President Donald Trump's tariffs, "presumably in the expectation that the White

House will find a workaround," said Matthew Ryan, head of market strategy at global financial services firm Ebury. The market reaction "has been far from euphoric thus far,"

he said in an email. “Trade negotiations are now left in somewhat of a limbo, as it is tough to see how Trump can justify imposing tariffs when it is not clear that he has the legal means to

do so," Ryan said. "A concern for markets will be that the ruling potentially prolongs the period of uncertainty, as any legal bypasses will take time.”
