As we all have experienced the Stock Market ebbs and flows and while not endorsing the scheme in any way, it may all boil down to a matter of timing. In other words thru the years of buying and adding to ones positions over the LONG term, the hopefull outcome will be somewhat of an averaging effect that might put you in an UP position but that all depends on the timing of your retirement and the overall condition or value of the market, right?
Sure if one had started at the PEAK of the bull and kept investing little by little all the way down, theory being that if and when things turn you "should" be in a position of increased value over the long haul. We are all looking at it in to short a time frame. Now of course inflation, outside market events, destruction of companys thru BR, etc. will have some effect but I would think that the limitations as to investment vehicles would be limited to those that would offer reasonable security at this time, all IMHO
