As interest rates fall, older and higher yielding bonds became more valuable. Now that long term government bonds yield less than 5 percent, so there is not much to gain.Seriously speaking, financial advisor recommends that retiree really need a strategy that is a bit more sophisticated particularly if they want their money to last through the third or sunset stage of retirement.

Save more when you’re working. As you approach retirement, you’ll need to reconcile your budget with your portfolio. For example, if you expect your annual expenses to be around $50K, then according to scientific financial calculation you may need at least $1.25 million in order to satisfy your expenses. Also depending on many factors, such as marker performance, life expectancy, you may not able to withdraw a large sum out of your investment. If you want your portfolio to last a life time, financial mathematics show that you may not withdraw more than 4.5% per annum; assuming your portfolio carries at least 60% in stocks.Financial advisor recommends retiree to invests in both short-term and long-term growth. One of the recommended investment strategies is to invest five year or more of living expenses in high quality bonds, some which will mature every year. For example, you may buy $50K worth of 1 year bond, $50K worth of 2 year bonds and so on. This strategy ensures that retirees will have income every year, plus access to the principle as each bond or group of bonds matures. You may then sell some stocks to repurchase another year worth of bonds set to mature in another 5 years. However, what happen if your portfolio suffers a bad year or two? In this case, you should hold off selling stocks; and if you have gains in any year, then you may invest in more years ahead. The rest of your portfolio can then be growth-oriented invested entirely in stocks.Another way of investment is to buy an immediate annuity with big enough payout to cover costs from health care insurance, taxes and living expenses.However you may want to wait until your second or third stage of your retirement before you purchase an annuity, because the payout is larger for an older buyer.
