"Maxwell Technologies (NASDAQ: MXWL) provides R&D services to the U.S. military and other government agencies; it's become the world's leading authority on ultracapacitors," says Timothy Lutts.

In The Cabot Stock of the Month report, he explains, "Ultracapacitors are handy little electronic devices that store and release electric energy more efficiently than batteries; they can be 10 times lighter than batteries and store and distribute energy 10 times more effciently than batteries."

"So what are ultracapacitors good for? Today, Maxwell-the primary American ultracapacitor manufacturer-is focusing its efforts on two fast-growing young industries: wind turbines and hybrid/electric vehicles.

"Stocks are so low that the best are bound to attract bargain-hunters ... eventually," says Timothy Lutts. One such value he highlights in The Cabot Stock of the Month Report is Royal Gold (NASDAQ: RGLD).

He explains, "Royal Gold doesn't own any gold mines. It doesn't mine gold. It doesn't buy gold. And it doesn't sell gold. It simply owns the rights to royalties from a variety of precious metals producers."

"The major benefit of Royal Gold's approach to the gold business is that it involves no capital costs, no operating costs and no legal or environmental liabilities. The major drawback? Well, we haven't found it yet.

"Royal Gold is not large. It has annual revenues of just $69 million and 34 million shares outstanding. However, Royal Gold is the biggest company in the world that derives its revenues solely from precious metal royalties.
