Stock market is up by 30% from March lows

But why?

Earnings are subpar, Treasury's last auction was a bust because of weak demand, the dollar is suspect, the stimulus is pork, the latest budget projects a $1.84 trillion deficit, the administration is berating investment firms and hedge funds saying "I don't stand with them," California is dead broke, health care may be nationalized, cap and trade will bump electric bills by 30% . . .
