Well... you can be in the stock market for the next two years. During those two years (under normal circumstances), interest rates should be rising. Two years from now, when the stock market is at its peak, sell stocks and buy long duration bonds. Hold those while the stock market tanks and interest rates go down. (Bonds increase in price as the interest rate declines; the longer term the bond, the bigger the price change.)

All that's assuming that Bernanke is right both in direction and in timing. It also assumes that interest rates will do the usual thing this cycle which, given the strange stuff that the government is doing to intervene, may not be a good assumption.

Note well: I am not a financial advisor, and this is not investment advice.

You can bet on the market going down. Just go to your banker and tell him to do it. The question is just, do you believe it?

Diversify. Try to have a portfolio of investments that include asset classes that will counter act any market falls.

Options on the SP500, good luck with that in a bull market though

Buy property, bitcoin, gold.
