I'm amazed at the amount of people on this forum that have bought into the buy and hold concept! That works in a bull market, but not in a bear or sideways market which we will probably be in for the next five or six years.
If those of you that have 401ks would have moved your money from mutual funds to government money or money market within your 401k at the first sign of recession, you would have saved thousands upon thousands of dollars. When the market bottoms out (I don't believe we have seen the bottom yet!), move your money back to mutual funds and enjoy the ride up!
