Much has been written about rare earth metals. They are used in electronics, batteries and specialized magnets. China controls more than 90% of rare earth production and has put a ban on exports of the minerals.

The largest miner of rare earths outside China is Molycorp (MCP), a U.S.-based company. The company mines lanthanide and molydenum. Lanthanides include cerium, lanthanum and yttrium. These exotic elements are used in cell phones, computers, X-ray film and TV glass.

Here's an interesting story, which speaks volumes about the psychological dynamic of the markets. On Friday the United States Department of Agriculture (USDA) will report on end-of-season inventories, often called 'ending stocks.' Traders are getting word the report may show inventories are lower-than-usual. Against that backdrop, as a trader you certainly don't want to take a short position. So what to do? You buy, of course.

Except for a brief sell-off to the 11,500 level, the market has moved quickly to regain lost ground and is now at new highs. Last week the USDA's crop report was bullish for grains. It's not surprising that Caterpillar (CAT) led the charge, up 1.7%. But there are always some losers. Office Depot (ODP) fell 11% after reporting a fourth quarter loss and Krispy Kreme Doughnuts (KKD), which also had a fourth quarter loss, fell 17%.

With a name like Drugstore.com (DSCM), there is little doubt what the company does. Unfortunately, the stock price has been miserable since the dot-com bust. All in all, it has remained in the low single digits. Then again, the company has had to deal with tough rivals, like Amazon.com (AMZN).

But Thursday, investors got a nice surprise. Walgreen (WAG) has agreed to buy Drugstore.com for $429 million. In early trading, DSCM was up a whopping 112% to $3.79.

NCT closed Wednesday March 23 at $6.02.

In making this move, management seeks to raise $85.6million for future investments and operations. This is the management that guided the company back from the grave.
