Eric has an article out this month in Harpers predicting Alt Energy is the next bubble. Interesting call, since most stocks in this space just got halved in the past few weeks (look at FSLR and STP for examples). If there's to be a bubble there, this would be a good time to buy for sure. Or not if that's not the next bubble.
I do like energy, with world population and wealth climbing, but coal and oil will dominate for years. That said I did pick up PBW the other day as my clean energy play.
Bernanke taking interest rates below the rate of inflation (again) is very likely going to produce another bubble somewhere. The US economy and US consumers won't be able to function without a new asset bubble, with debt maxed out and incomes flat.
So where will it be?
Gold? Oil? Euros? Stocks? Baseball cards? Ramen?
