I don't know what an investor should do--I just watch the money move. Money will always flow somewhere, because it has to.

Where will it flow next? Probably wherever it isn't this time.

Right now commodities (a.k.a. "stuff") is getting the attention, as some have predicted for years (someone's always predicting something for years, until it comes true).

Recently: Tech -> Housing -> Stuff -> ?

A problem for people with money to worry about. ;)

this question is why the financial institutions exist. companies that do nothing but solicit your money and invest it for you while living off a percentage don't really know all that much about how the markets work. Like the previous poster said, you have to be a contrarian. It's exactly that ability to invest in something when everyone thinks it is worthless that makes people rich. stocks were dirt cheap in the 80's, commodities were dirt cheap in the early 2000's, you have to figure out on your own where to go next.

I will say that these trends seem to have followed a 17 year period (on average) during the 20th century. If this remains true america has another 9 years of slow economic growth (and commodities have another 9 years of bull). But we must always beware of the induction fallacy :)
