Watching some financial stocks just get wiped out in recent months, I often hear a voice in the back of my head, and it is the same voice as one of those dealers in Las Vegas who coolly tells you as he sweeps up your chips after you’ve busted in blackjack: “Thank you for playing, ladies and gentlemen.”
