In this clip from the March 10, 2009 edition of CNBC's Squawk on the Street, the late Mark Haines tells Erin Burnett, "I think we're at a bottom. I really do." As the credit crisis continued to swirl, the Dow had closed the day before at 6,547.05, a staggering 54 percent plunge from its all-time closing high above 14,000 in October of 2007. It was "going out on a limb" at the time, but has proved to be one of the best market calls ever heard on CNBC. March 9 turned out to be the bear market closing low. In the three years since Mark's call, the Dow has almost doubled.
