Each week I recap the results of the WilderHill New Energy Global Innovation Index, symbol NEX, and published by New Energy Finance Ltd. The index consists of approximately 90 stocks from 22 countries. The NEX is the tracking index for the PowerShares Global Clean Energy Portfolio ETF (PBD: 11.24 0.00 0.00%). For reference, the NEX has a 52 week high of 436.21 and closed 2008 at 177.99.

For the week ending Friday, 1/12 the NEX lost 6.5%, closing at 179.22. The NASDAQ and S&P 500 were down 5.5% and 6.2% for the same period. All sectors in the NEX lost ground for the week led by ‘energy conversion’ which lost 11.4%. This is the same sector which was the top gainer the previous week. Oh fickle fate! The two largest sectors in the index, solar energy and wind energy lost 10.2% and 6.1%, respectively. Energy efficiency was the best of a bad bunch, losing only 2.8%.
