Asset allocation when retirement is already secure
he general advice I get is that the younger you are the more higher risk investments you should include in your portfolio. I will be frank. This is a rule of thumb given out by many lay people and low-level financial advisors, but not by true experts in finance.  It is little more than an old wive's tale and does not come from solid theory nor empirical work.  Finance theory says the following: the riskiness of your portfolio should (inversely) correspond to your risk aversion.  Period. It says nothing about your age.  Some people become more risk-averse as they get older, but not everyone.  In fact, for many people it probably makes sense to increase the riskiness of their portfolio as they age because the uncertainty about both wealth (social security, the value of your house, the value of your human capital) and costs (how many kids you will have, the rate of inflation, where you will live) go down as you age so your overall level of risk falls over time without a corresponding mechanical increase in risk aversion. In fact, if you start from the assumption that people's aversion is to not having enough money at retirement, you get the result that people should invest in relatively safe securities until the probability of not having enough to cover their minimum needs gets small, then they invest in highly risky securities with any money above this threshold. This latter result sounds reasonable in your case.  At this point it appears unlikely that you will be unable to meet your minimum needs--I'm assuming here that you are able to appreciate the warnings about underfunded pensions in other answers and still feel comfortable.  With any money above and beyond what you consider to be prudent preparation for retirement, you should hold a risky (but still fully diversified) portfolio.  Don't reduce the risk of that portion of your portfolio as you age unless you find your personal risk aversion increasing.
