Just behind the VIX products in the list of worst performers is a pair of solar ETFs. The Guggenheim Solar ETF (TAN) and the VanEck Vectors Solar Energy ETF (KWT) shed more than 42% apiece. TAN and KWT are ending the year at their lowest levels since 2012-2013, as the once-positive long-term demand story is overshadowed by a host of negative factors.
From free-falling solar panel prices to the devastating bankruptcy of former solar heavyweight SunEdison to regulatory uncertainty following Trump's win, there's been no shortage of bearish catalysts for solar ETFs this year.
It's not all bad news for the industry, though. For the first time ever, more electricity-generating capacity from solar was added this year than from wind and even natural gas.
The next five ETFs on the worst-performers list had year-to-date losses ranging from 30 to 40%, including three single-country funds.
The Global X MSCI Nigeria ETF (NGE) lost 38.4% in the period as Africa's largest economy fell into an oil-induced recession. Low oil prices combined with a 27-year low in the country's oil output battered the Nigerian economy and stocks all year long.
Meanwhile, the VanEck Vectors Egypt Index ETF (EGPT) fell by 31.8% this year, most of that coming in November after the Egyptian government floated its currency, resulting in a 50% plunge in the Egyptian pound against the U.S. dollar.
