In this week’s commentary, we want to draw your attention to a significant market anniversary. Five years ago, on May 6, 2010, the U.S. stock market experienced a “flash crash” when the Dow Jones Industrial Average plummeted nearly 1,000 points in minutes, erasing almost $1 trillion in market value. The Dow immediately reversed itself and regained much of the lost ground that day. The event, caused by a large institutional trading program, wast the largest single day drop in market history and caused an immediate media frenzy.
