Below is a list of the best performing S&P 500 stocks on their earnings reaction days so far this season. Under Armour (NYSE:UAA) (NYSE:UA) ranks at the very top of the list with a huge one-day gain of 27.71% after it reported a triple play on October 30th. (A triple play is a company that beats EPS estimates, beats revenue estimates, and raises guidance.)
Vulcan Materials (NYSE:VMC) ranks second with a gain of 17.49%, followed by Akamai Tech (NASDAQ:AKAM), Newfield Exploration (NYSE:NFX), and Twitter (NYSE:TWTR). Other notables on the list of big winners this earnings season include International Paper (NYSE:IP), Ford (NYSE:F), PayPal (NASDAQ:PYPL), Church & Dwight (NYSE:CHD), Starbucks (NASDAQ:SBUX), General Motors (NYSE:GM), Procter & Gamble (NYSE:PG), DowDuPont (NYSE:DWDP), and Whirlpool (NYSE:WHR). These certainly aren't your typical high-fliers!
On the downside, Mohawk (NYSE:MHK) has been the worst performer this earnings season with a one-day decline of 23.86% after it reported a reverse triple play on October 25th. The stock missed EPS estimates, missed revenue estimates, and lowered guidance.
