Keep track of where it has been; you don't need to buy at the absolute lowest point, if it creeps back up you can slowly buy in again.
Have a look at trackers like the S&P 500 after previous crashes, it takes 3-6 years for the market to return to its previous highest value. Or six months in the case of the panny-D crash.
