The number of investors with a bearish outlook plunged by more than a third in one week according to a widely followed investor survey released Wednesday, the largest amount of bears to throw in the towel in this poll since 2003.

The survey ending April 5 came as the indomitable Dow Jones Industrial Average touched its highest intraday point since the two-year bull market began.

Middle East turmoil, an Irish bailout, fears of a municipal bond crisis, a nuclear disaster in Japan and an impending end to the Federal Reserve’s quantitative easing has failed to keep the market down this year. And the bears are simply done fighting the tape.
