Total ISA investment value is the total value of an investment on 31/01/2024 if the maximum ISA limit for each year had been invested annually from 1999 to 2023, with the investment being made on 6 April each year.

Brodie-Smith comments: “It’s been a challenging time for investors recently, with high inflation coupled with geopolitical tensions and an uncertain outlook.

“In difficult times, it’s important for investors to take a long-term approach to their investments. Investment trusts have been in existence for more than 155 years, surviving two World Wars, the Great Depression, the 1970s era of high inflation, the tech boom (and bust), the financial crisis and the pandemic. 

“They have a fixed pool of capital, which means investment trust managers can take a long-term view, holding onto assets during market downturns, rather than being forced to sell them at cheap prices.”

Jim Strang, chairman of HgCapital Trust, said it was “very heartening that the company has been able to deliver such compelling gains for shareholders over the last 25 years”. He said the investment performance was a “solid endorsement of the private equity model”.

Mike Seidenberg, portfolio manager of Allianz Technology Trust, called the gains “fantastic”. He said: “As we often remind investors, we are arguably living in the golden era of technology where companies across most industries become relevant or irrelevant depending on their adoption and use of technology.”
