At your age, you should just keep putting money on a regular basis into your 401k or IRA, keep it in sound funds that you don’t need to manage often (ie, don’t bother looking at them any more than perhaps once/year) and not mess with it.
Dollar cost average.
For someone in your age bracket, the stock market just went on sale. You should avail yourself of the bargain.
Thanks everyone for the good advice!
