2016 marks Obama's 8th year in office. Which means we should've seen this stock market collapse coming. In a note to clients on Tuesday, J.C. O'Hara, chief market technician at FBN Securities, noted that going back to 1920 the eighth year of a US president's term has been bad news for stocks. As O'Hara's chart shows, the eighth year of a presidential term has seen the Dow fall about 15% on average since 1920.
