Should I sell a fund that’s underperforming?
31 July 2025
Question by Amir
I’ve got a fund in my ISA that’s been going down for over a year but everything else seems to be doing better. Is it time to ditch it or should I hold my nerve?

Hi Amir,
If your ISA fund’s been going nowhere while others are flying, don’t panic - sideways movement isn’t always a red flag. It could be in a sector that’s temporarily out of favour, or built for stability rather than sizzle.
If you’re investing long-term and the fund still fits your goals, holding tight might be wise. But if it’s consistently underperforming its benchmark
, or you’ve lost faith in the strategy, it might be time to switch. Just make sure any new fund improves your diversification.Smart investors review regularly, diversify broadly, and resist knee-jerk reactions. Time in the market beats timing it. So unless your fund’s truly gone off-piste, staying the course could pay off.
Hope this helps!
