Does Asset Allocation Affect Withdrawal Rates?
One other important factor from William Bengen’s original study is asset allocation. In particular, he recommended that retirees maintain a stock allocation of 50-75%, writing, “I think it is appropriate to advise the client to accept a stock allocation as close to 75 percent as possible, and in no cases less than 50 percent.”
