I already stated in my post that I was cherry picking periods, the point is that to participate in the market is always a matter of timing. People dont control when they were born and when they start their careers and often when they end. Many people were taught buy and hold meant you made money, the truth is that it helps but you could still get royally goat fucked depending on when you entered and left the market even if you held for a decade.stuff
I'm a big fan of buying index funds and/or target retirement funds but I think with time and education it's possible to make some investment decisions to turn things "slightly" more in your favor. If the S&P 500 is trading at an 18 PE well then unless I think we are about to have the mother of all productivity increases I'm going to reduce my positions, and if the market is trading at a PE of 11 then unless I think Glenn Beck is right and this country is utterly doomed then I'm going to increase my stock positions. I don't believe that is reckless investing.
One of the other ways to protect your selves form spikes is to always be buying. Dollar cost averaging greatly reduces period risk, the dangerous game is taking large sums in and out of the market in a short time frame. Murphy will fuck you every time.
