Is YOUR 20-30 yr time frame going to mirror history ?My questions to you and the ET professionals are:
1. If my time horizon is 20-30 yrs, why don't I put everything into the asset class with the highest return (for example RUT rather than DIA or SPY)?
2. If over most 20-30 yrs period, RUT consistently beats DIA, why is the measure of risks consistently higher for RUT?
3. Is Beta the correct measure of risk if not what should I use?
