The rising tide wasn't able to raise all stocks.

The 2010s saw US equities enjoy a record-long bull market as stocks endured the end of the financial crisis, Fed rate hikes, trade-war woes, and recession fears.

The S&P 500 is up roughly 187% in the decade-to-date, yet some members of the key index lost more than half of their value over the period.

The decade wasn't without its down years. The index closed lower in 2011, 2015, and 2018, but never fell more than it gained in the previous year. This year the S&P 500 is poised to deliver a 28% jump, which would be the biggest annual surge since 2013.

Here are the 11 worst performing S&P 500 stocks through the decade, ranked in decreasing order of return. Data is as of 2:15 p.m. ET on December 19.
