I am wondering about the sustainability of the new record for the DJIA. This represents an average p/e ratio of 15.5, which translates to a cost of raising capital of 6.5%. Since the current prime rate is only 3.25%, the market does not seem to be overvalued at this time. However, if interest rates return to "normal" levels, the market may be negatively affected. In this event, will investors abandon equities and return to debt instruments? If not, where will all the money go?
