Short Sales Break Record on NYSE; Market Bulls Get More Bullish

May 29 (Bloomberg) -- Short sellers are betting against U.S. stocks like never before as the Standard & Poor's 500 Index approaches an all-time high. That's making some of the biggest bulls even more optimistic.
``What the short seller appears to be doing is doubling down,'' said Kenneth Fisher, who oversees about $40 billion as chairman of Fisher Investments in Woodside, California. ``You love to see it, because if you believe there is a basic driver to the bull market, they're going to get run over.''
