The S&P 500 is on pace for its best year in two decades, but not all of the index’s stocks are posting gains in 2019.

While tech stocks flourished in the 12-month period, many of the key index’s lagging companies are retailers struggling to compete with e-commerce giants like Amazon. Gap, Macy’s, and Kohl’s were all among the worst performers in 2019. Online sales surged to record highs in the holiday season while sales at department stores sank 1.8% year-over-year, signaling a continued weakening for traffic at retail locations.

One tech stock was also among the biggest losers of the year, despite its sector gaining more than any other group of S&P 500 stocks. DXC Technology tumbled the most of its peers, dragging the sector lower after the firm slashed its full-year outlook in August.

Even Warren Buffett-backed Kraft Heinz tanked through the year. The company hit a record low after its August earnings missed analyst expectations and the company ate a $1.2 billion charge for business writedowns.

Here are the 11 worst-performing S&P 500 stocks of the year, ranked in ascending order by value lost. All data is as of 3:00 p.m. ET December 27.
