the problem with the go even more aggressive as you age is there is a tipping point because you have less time to recover . as we reach older ages spending on healthcare tends to ramp up . last thing you want is a serious downturn reducing your balance by 20% as spending ramps up . it can be a non event like 2008 if recovery is v-shaped and quick as it was in 2008 . but if recovery is slower and more u-shaped it can hurt you bad .
usually by our older ages more money is not going to change a thing in our lives , but a big drop may very well change things .
every time we have a downturn there are seniors who kept the carrot on the stick for to long and regret it . so i find you need a safe comfortable level of allocation or portfolio strategy to smooth out the peaks and valleys . you can end up very close to the same points but depending on your portfolio construction you can have a smooth ride or one hell of a ride to get to about the same spot .
there are portfolio's that have had a fraction of the swings of more aggressive models that produced not only better returns but had far less swings and losing years .
you can see some of the most popular ones here , personally i use the golden butterfly and am test driving it now with substantial dollars .
