While the cap-weighted S&P 500 gained 19.42% on the year, the average stock in the index was up less than that at just over 18%.

There were exactly 50 stocks in the S&P that gained more than 50% on the year, and there were only 3 that gained more than 100%. We were a bit surprised that only three stocks posted triple-digit returns given the year that markets had. We were even more surprised to see a Utilities stock at the top of the best performers list! That’s right — NRG Energy (NRG) was the top performing stock in the S&P 500 in 2017 with a gain of 132.3%.The other two triple-digit gainers were Align Tech (ALGN), and Vertex Pharma (VRTX).Wynn Resorts (WYNN) and Boeing (BA) rounded out the top five with gains of 94.88% and 89.43%, respectively.

Other notables on the list of S&P 500 winners include NVIDIA (NVDA), Activision Blizzard (ATVI), Adobe (ADBE), Caterpillar (CAT), Best Buy (BBY), Amazon (AMZN), Netflix (NFLX), and Facebook (FB). All of these names gained more than 50% in 2017.

It’s tough in any year to be on the loser’s list, but it’s even tougher in a year when the S&P gains as much as it did this year. Below is a list of the S&P 500 stocks that fell more than 20% in 2017. Range Resources (RRC) and Under Armour (UAA) top the list with declines of 50%+. General Electric (GE) is by far the most high-profile name on the list of losers with a huge drop of 44.78%. Other notable losers include Mattel (MAT), Macy’s (M), Baker Hughes (BHGE), Foot Locker (FL), TripAdvisor (TRIP), Chipotle (CMG), and Campbell Soup (CPB).
