And no, this black swan has nothing to do with the movie starring Natalie Portman.
So what exactly is a black swan event?
Carol Schleif, deputy chief investment officer at Abbot Downing, broke it down for investors.
"A Black Swan event is a nonpredictable, out of the left field, kind of event," she explained.
"And that that's what makes it tough because they're the things that come all of a sudden and explode them. It might be a tsunami in a certain area if we had some sort of event that took out the New York stock exchange or something like that's a black swan kind of event. Um, the housing crisis and things like that. People in retrospect too, there were black swan events and the severity probably was, but people knew for a long time that there was a lot of funky things building in the markets and what was going on back then," she continued.
