Smart-Grid Plays

On Oct. 19, Cramer highlighted smart power meter manufacturer Itron (ITRI Quote). Since then, the stock has risen 27%.

But Cramer said there's also another way to play the smart-grid market with Cooper Industries (CBE Quote), a stock which he owns for his charitable trust, Action Alerts PLUS.

Cramer said smart-grid technology will be a $200 billion business worldwide in 2015, and that plays right into the hands of Cooper, which derives 88% of its revenues from electrical products.

Speculative Energy Play

Continuing on his smart energy grid theme, Cramer recommended little known Telvent (TLVT Quote), as a speculative way to play the coming smart-grid revolution.
