On Tuesday it was hard to tell professional investors from thrill seekers who just stepped off that latest theme park ride. Both were doubled over – some elated others near tears - all whipsawed by the Great American Scream Machine.
In fact, investors probably had it a little worse than people on the regular roller coaster - the market reversed directions six times before the wild ride ended.
”We moved 852 Dow points in an hour and 42 minutes,” says OptionMonster Jon Najarian.
And like any good theme park attraction, the biggest whoosh happened at the very end with stocks surging higher into the close – making Tuesday the stock market's best day in more than two years.
Of course, that was after a dizzying drop of more than 17% over the past two weeks and more than a 600 point drop in the Dow, just one day earlier.
"This was a war," says Fast trader Tim Seymour. "The Street wanted to test its resolve."
