Hi Clive I read a study where it was suggested to be near 100% stocks till near retirement and then gradually go to 50% stock. After retirement you would spend from the cash / bond portion gradually increasing the stock %. In this way you would potentially avoid sequence of event risk ( market crash just at retirement which blows up your account ). It was thought it was better to INCREASE % OF stock in retirement. I think AIM works good enough. Toofuzzy
