I think this is the first year that the Dow Jones Industrials Average (DJIA) has ever gained 5,000 points in a single year. In fact, the Dow Jones was up every month of 2017. That's never happened before in history.
In fact, we've gone 14 consecutive months without a decline and not only were we up every month but 2017 represented the lowest year ever of stock market volatility meaning that even though the market was going up it barely ever went down so it never made anybody nervous.
