Another stock market circuit breaker today, the fourth in two weeks. When the S&P 500 went down 7% on the day a mandated 15 minute time out was triggered. The Dow was below 19,732 much of the day, where it was when Trump was inaugurated. All of the gains of the Trump Bump were wiped out. Both the S&P and Dow rallied in the last twenty minutes of trading to finish and the Dow finished above 19,732. S&P -5/18% for the day, DJIA -6.30%.
