The week started out on a good note, after Federal Reserve Chairman Ben Bernanke cheered the market with his assurance that the Fed will continue to pump easy money into the U.S. economy. The optimism waned quickly, though, and the major U.S. indexes spent the next three days giving back some of Monday's gains. Why? Perhaps investors realized that Bernanke's assurance that the weak economy necessitated accommodative monetary policy underscored the fact that, well, we have a weak economy.

Joining in on the big gains during the week were Molycorp
The rare-earth mining industry is steaming ahead. Or at least that's the conclusion that investors drew from the earnings report from Chinese miner Inner Mongolia Baotou Steel Rare Earth Hi Tech. The company's earnings soared 363% on revenue growth of 119%, as China's appetite for rare-earth metals continues. The strong report from Inner Mongolia Baotou drove investor excitement for other rare-earth miners, such as Molycorp. However, all may not be lollipops and unicorns -- as my fellow Fool Sean Williams pointed out, Inner Mongolia Baotau noted that prices for rare earths continue to fall and could hit earnings for the back half of the year.
For Teekay, the week's boost came largely on the back of an upgrade from Wall Street research firm Dahlman Rose. Dahlman highlighted the recovery in oil prices and suggested that a sustained recovery would be good news for Teekay and fellow tanker operators such as Frontline. It raised both Teekay and Frontline's stock ratings to buy.
By week's end, Molycorp had tacked on 15% while Teekay was up 13%.
