NEW YORK, April 3 (Reuters) - Large investors are

looking for ways to diversify their allocations geographically,

but are mostly sticking with their U.S. assets for now, said an

executive at Goldman Sachs ( GS ).

"Large allocators are reluctant so far ... but they are

concerned," said Marc Nachmann, global head of asset and wealth

management at Goldman Sachs ( GS ).

He was referring to concerns over U.S. trade policies fueled

by U.S. President Donald Trump's imposition of sweeping global

tariffs.
