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.

Monday's buying drove corn prices to a record high of $7.6025 per bushel, up 24.25 cents, as reported in the Wall Street Journal. Country Hedging, a brokerage firm, said: "Federal forecasters could drop the projection to less than 500 million bushels from last month's 675 million. This is a 15 year low."

NetApp (NTAP), the fourth-largest player in the external disk storage market, creates innovative storage and data management solutions for small and medium-sized companies around the world. It competes mainly with other storage majors like EMC (EMC), IBM (IBM), HP (HPQ) and Dell (DELL).

Copper was the darling of commodity traders. The price rallied from about $6,400 per ton to a record $10,190 in the past year, The Financial Times reports. Momentum was strong and it looked like there was no end in sight. But now, prices have dropped off a bit and miners are worried that the rally has hit a brick wall. The main concern is that what drove drove prices skyward -- China's demand -- may be slowing, according to the FT.

One indication of the slowdown is the amount of stocks held in exchange warehouses. At the LME Asia + Shanghai exchange warehouses, copper stocks have increased from below 150,000 to over 325,000 tons. That buildup has worried miners. The companies affected are Freeport MeMoRan (FCX), BHP Billiton (BHP), Xstrada (XSRAF), Anglo American and Brazil's Codelco, according to the Financial Times.

Let's go back to the financial crisis and the practices that brought this country to its knees. Banks developed a fancy scheme whereby they absolved themselves of all risk from the loans they made. They simply wrapped them up in a bundle and sold them to someone else. What they were doing is essentially packaging and reselling "junk."

When the news of how bad things were became known, the markets froze and collapsed. No one knew who had which securities, and if they did, they didn't know their true value.

An invasion of U.S. oil fields by Asian buyers is happening. Recently, companies from Korea, China and India have bought land in the oil-rich states of Texas, Colorado and Wyoming, according to Reuters.

In one of the biggest land deals, Korea National Oil (KNOC) bought one-third of Anadarko Petroleum's (APC) land holdings in South Texas for $1.55 billion. The purchase of 80,000 acres is located in the Eagle Ford Shale section, which is believed to have rich deposits of oil, natural gas and liquids, according to Reuters. KNOC also will receive 16,000 acres in the Pearsall Shale in South Texas.

The rebuilding of Japan will require large amounts of basic materials. One such material is cement. Cement is used in virtually every type of large building or factory.

It might be helpful to look at some cement stocks. Here are just a few, along with their recent share prices:

• Lafarge Coppee (LFRGY): $14.00. One of the world's largest cement and gypsum manufacturers.

Every major crisis has its winners and losers. With the Japanese crisis, most prominent may be the uranium stocks. As you might guess they are getting hammered. The presumption is that governments will be reluctant to approve nuclear projects in the wake of Japan's nuclear meltdown.

Here are just a few companies and recent stock prices:

• Denison Mines (DNN): $2.55, down 74 cents. Denison is a worldwide mining and exploration company. It has two uranium waste recycling plants in the U.S.

The crisis in Japan will require all sorts of construction materials for rebuilding destroyed buildings and factories. Steel is used in most construction projects. Here in the United States, U.S. Steel (X) is a dominant player.

Let's look at the company profile and earnings reports. "Based in Pittsburgh, the company operates mills throughout the Midwest, in Ontario, Canada, Serbia and Slovakia. The company makes semi finished steel, tubular and plate steel and tin products. Its annual production capacity is about 32 million tons of raw steel. The company's customers are from autos, chemical and steel service center industries."

The Chinese government released trade data that portrays a $7.3 billion deficit. Is that believable or just convenient amid the international pressure to raise the value of their currency? We can hardly believe what comes out of Washington, so data coming out of China has to be quite suspect.

I'm sure they retained qualified independent auditors to ascertain the validity of the figures -- yeah right ...

The publishing industry is experiencing an new and booming business in e-books. According to Forrester Research, consumers spent $1 billion on e-books in 2010. That number is expected to triple by 2015. In the US there were about 10 million e-readers in circulation in 2010, triple that of 2009.

The two leading players in the e-reader market are Amazon (AMZN) with its Kindle and Barnes and Noble's (BKS) Nook. With these readers a single reader can use the reader or a friend can be added as long as they know each other's email, according to the Wall Street Journal.

The market for single cup roasters is estimated at $4 billion, according to Reuters. Single cup coffee roasters are growing in popularity, especially in business offices and waiting rooms. Naturally, coffee roasters like Green Mountain Coffee (GMCR) and Starbucks (SBUX) want a piece of the action.

The single cup roasters provide several advantages to having coffee in larger coffee pots. For one thing, coffee which sits for hours in a pot loses some of its fresh flavor or becomes bitter. Enter the single cup roaster. You simply pop a small container of coffee in the machine, and viola, you get a single cup of coffee with little or no mess, and always fresh.

Warren Buffett invested $232 million in BYD (BYDDF), a Chinese auto maker during the financial crisis, as reported by Reuters. As of December 2010 Buffett's 225 million shares were worth $1.18 billion. In 2009, the shares were valued at just under $2 billion. So from 2009 to 2010, Buffett's Berkshire Hathaway (BRK.A) lost about 40% of his investment.

But that is just the beginning. Now there is criticism surrounding the new Chinese car, dubbed the hybrid car F3DM.They center around two major areas, authenticity of the design and the overall workmanship of the car itself.
