Let me first start by admitting that I am almost clueless about Unit Trusts. However a few years back I decided to support a friend who is a Public Mutual agent, and ever since funds have been withdrawn from my EPF to go into unit trusts that he manages. But it seems like his unit trusts have been underperforming (versus EPF's return) for the past few years since we started.

Now he's asking to withdraw even more from my EPF. Should I stop all of this and just keep the funds in EPF? Or let him continue with the unit trusts?

To be honest I don't really know. Just that when I met him about 2-3 months ago, I know that only some are positive, but still nowhere near to cover the losses.
Thank you guys for giving your opinions. So far I'm seeing that it's best to just keep the funds in EPF.
