Wealth and investment managers are warning clients to take a "longterm view" after Donald Trump's tariff plan reduced the value of investment portfolios on the stock market.

Many investors have seen losses after the US introduced tariffs on countries' imports, sending shares around the world down.

Investment companies are telling concerned clients that dips in value for short periods of time are "normal".

Gianpaolo Mantini, a partner at wealth management firm Saltus, said he had received "several" calls from concerned clients about Trump's tariffs.

"This is not the first, nor will it be the last time that markets suffer a temporary correction," he said.

Andrew Prosser, head of investments at InvestEngine, added: "Markets inevitably go through rough patches - whether caused by geopolitical instability, extreme weather events or economic tariffs - but people who invest in a diversified portfolio need to remember it's about long-term returns rather than quick wins."

Jonathan Raymond, investment manager at Quilter Cheviot, said: "Most clients have been through the Covid sell-off in 2020 and the 2022 equity market falls amongst other events and, in the main, are fairly immune to these sort of periods.

"Many are cognisant that these periods of volatility are the 'price of admission' for attaining good returns over the medium to longer term."
