It may be a bit late but consider moving most of your pension to bond funds or cash within the pension then start reinvesting gradually when the markets show signs of a rebound. If it is a decent pension there should be no cost to move funds within it, the rip off pensions could charge anything up to 5%. The markets are going to be very volatile so if you do not understand them play safe. I did post on the forum about three months ago that a shift to gold would be a good move, which was. This was followed by a move to bonds and a few favorite low risk funds when gold started dropping, but now sit on cash until the markets pick up for a couple of weeks, then gradually reinvest. Anyone with stocks and shares ISAs should do the same.
Consider using a good website which shows the performance of all Pension and ISA Funds so at least you are not totally in the dark as to where to invest, but do keep checking the performance of the funds, as in the last week some funds made 10% but others lost 30%, and check that your pension company does not charge you for switching funds. If it does charge you for switching consider a different pension company that does not charge for switches.
