The big question is, 120% of what? The bigger your pot the more your 120% will produce.
So why not turn some of your pot into your own choice of shares, because most of the funds that your drawdown is invested in are the same old top ten companies with very little growth and just relying on dividends.
If you look at the performance graphs of your funds since 2008, they all follow the same path downwards during 2008/2009, few of them stopped the decline and straight lined during the recession.
You can choose shares for growth, and that growth can be far more spectacular than your present funds can produce, plus you can turn them back into cash if things look bad or apply stop losses if you are concerned about the future.
Of course, there is one drawback. You have to put some effort in to learn the ropes, but, HL has a screen where you can have a fantasy share dealing account so there's no risk and there's a mountain of help and info on the net to help you.
Give it a try, it's not quite as difficult as you might think!
