YELLEN SPEAKS, STOCKS RISE THEN FALL: Here's what you need to know

Stocks gave up serious early gains for a wild swing during a day that was full of speeches from members of the Federal Reserve.

The Dow was over 100 points into the green on Friday directly following Federal Reserve Chair Janet Yellen's speech at the Jackson Hold conference. After hawkish comments from Vice Chair Stanley Fischer and others, however, all the major averages dove lower and ended the day in the red.

The moves, however, keep the now 35 day streak without a 1% move in either direction by the S&P 500 intact.
