Recent statistics reveal Wall Street analysts are more bearish than ever. From Bloomberg.com:

“Short” interest rose to 3.1% of shares listed on the New York Stock Exchange in May -- higher than any level since the Great Depression.
“Sells” in the total market have increased to 6.9%, compared with 1.9% in March 2000, moments before the tech wreck.
“Buy” recommendations fell below “hold” calls as a percentage of total U.S. stock picks for the first time since Bloomberg began tracking in 1997.
A bull market climbs a wall of worry, the old-timers say. Perhaps there is still room for new record closes on the Dow and S&P after all.

I keep looking for the top, it will come because these shorts will be driven out as the market makes new highs. This will be the exhuastion point then the market will head south. Another Wall Street saying is that they never ring a bell to tell you when the top is and or the bottom.
