Short Covering Could Stoke Another Solar ETF Rally

A familiar fundamental catalyst could again boost TAN: Short covering. Two TAN holdings – SolarCity and GT Advanced Technologies (NasdaqGS: GTAT) – currently rank among the most shorted stocks on Wall Street with short interests of 29.2% and 34.3%, respectively, according to Business Insider. Those stocks combine for 12.6% of TAN’s weight. [Solar ETF’s Secret Sauce]

Additionally, solar sector short interest is on the rise. Recent NASDAQ data indicate SunEdison’s (NYSE: SUNE) short interest has jumped to 25.6% while SunPower’s (NasdaqGS: SPWR) has climbed to 26.3%, according to 24/7 Wall Street.

First Solar’s (NasdaqGS: FSLR) short interest is up to 15.3% of the company’s float. First Solar, SunEdison and SunPower combine for over 21% of TAN’s weight.

Heavily shorted holdings can actually work in TAN’s favor. As the Wall Street Journal recently reported, a well-oiled securities lending operation has enabled TAN to outperform its underlying index by an average of 3.6% per year. With demand rising to short TAN’s holdings, those securities lending fees collected by the issuer could again work in favor of investors that are long the ETF.
