Thursday's U.S. stock market trading session qualified as a genuine stock-market "panic." They're rare, fortunately, so they're memorable.
You can say you were there.
According to the volume analysts at Lowry Research Corp., this stock market panic was on par with the mini crash of October 1989, when the Dow Jones Industrial Average plunged 6.9% in a single day. But it wasn't on par with the famed session of October 1987, when the Dow plunged 22.6% in a day.
