Difficult to know what to do in this situation. Definitely, conventional advice would be to sit tight and ride out the current storm. This is what I had intended to do with my EBS Summit Fund, for my sins, Global Leaders which I started as an SSIA. I am now at the end of my 6th year with this fund and it has proved very disappointing.
They say 10 years is a reasonable timeframe with equity investments but I must admit that with 4 years to go(?) I don't have any great confidence that this one will come good!! The Growth Fund might perform better!
