NEW YORK ( TheStreet) -- Clean Edge and Nasdaq's three benchmark clean-tech stock indices saw another week of mild positive movement, as the Nasdaq Clean Edge Green Energy Index (CELS) was up 1.76%, the Nasdaq OMX Clean Edge Global Wind Energy Index (QWND) higher by 0.80% and the Nasdaq OMX Clean Edge Smart Grid Infrastructure Index (QGRD) up 1.87% last week from the one before.

The overall market also moved higher -- the S&P 500 gained 1.04% and the Nasdaq was up 0.87% -- while AMEX Oil grew 4.38% from the previous week.

CELS -- up 1.76% for the week and 20.22% higher than a year ago -- tracks U.S.-listed clean-energy companies and is divided into four categories: advanced materials; energy intelligence; energy storage and conversion; and renewable electricity generation and renewable fuels. Of the 50 total component securities, 32 experienced gains and 18 lost ground.

CELS' best performer for the week was China-based PV product maker SunTech Power (STP), gaining 20.20%. Rounding out the top five CELS performers were electronic materials provider Rubicon Technology (RBCN - Get Report), up 17.61%; solar cell and module maker SunPower (SPWRA), higher by 12.47%; power management device maker O2Micro International (OIIM - Get Report), up 11.92%; and Chinese solar manufacturer LDK Solar (LDK), 11.84% higher for the week.

CELS' worst performer last week was wind energy product and service provider Broadwind Energy (BWEN - Get Report), declining 14.88%. Other worst performers included smart meter maker Itron (ITRI), losing 8.96%; demand management firm EnerNOC (ENOC - Get Report), down 8.15%; LED and solar manufacturing equipment provider Veeco Instruments (VECO), retreating 6.38%; and network infrastructure product maker Echelon Corporation (ELON), 5.97% lower for the week.

QWND -- 0.80% higher last week and 22.79% lower in the last 12 months -- includes companies that are primarily manufacturers, developers, distributors, installers and users of energy derived from wind sources. Of QWND's 18 pure-play components, seven saw gains, 10 experienced losses, and one was unchanged for the week.

QWND's best pure-play performer for the week was wind turbine manufacturer Nordex (NDX1), up 6.86%.
