You want to bet that the Dow will never again be materially less than 15,000?
Oh wait. You are betting that. You are a buy and holder.
Of course you also would not risk $50k for a 1 in 4 chance to win $1 million and think that when the value of your holdings goes way down you haven't really lost any money so I realize I am not talking to the brightest guy on the planet.
We will see what happens. Time will tell.
I agree with Flagpole.
