Reflect for a moment. How did you think the stock market would react when President Clinton was impeached in December, 1998 (Dow 9,181)? How about following the Y2K transition (Dow 11,497)? What about after the 9/11 attacks (Dow 8,847)? The Iraq invasion (Dow 10,403)? Or when the federal government had to step in and rescue the banks and auto companies (Dow 10,850)? Or in April 2016 (Dow 17,733)?
