A solar energy ETF that has shed about three-quarters of its value the past year is preparing a 1-for-15 reverse share split.

Market Vectors Solar Energy ETF (NYSEArca: KWT) will undergo a reverse split on July 2., according to manager Van Eck Global.

The price of a share will increase but the ETF’s shares outstanding will decline.

Reverse splits can lessen trading costs for ETF investors because they may help reduce bid-ask spreads.

The solar ETF was down 74% for the year ended June 28, according to Morningstar.
