Applied Materials (AMAT) is the world's largest semiconductor producer. The company has diversified and is producing solar power cells, but its main revenue stream is still mainly coming from crystalline silicon technology.

The company had blowout earnings in the fiscal first quarter, with income of $506 million or 38 cents a share, up from $83 million or six cents a share a year earlier, as reported in the Wall Street Journal. Revenue rose 45% to $2.69 billion from $1.95 billion.

ARM Holdings (ARMH) is far away from Silicon Valley. Its headquarters are on the campus of Cambridge University in England. ARM holdings has carved out a unique niche in the computer chip market.

We recently launched coverage of Kayak with a roughly $800 million valuation. Unlike online travel agencies like Expedia (EXPE) or Priceline (PCLN), Kayak does not provide online bookings directly but provides consumers a one-stop research solution to best fares along with other value-added services like flight status updates and pricing alerts.

We believe advertising revenues make up over 60% of Kayak's valuation while referral fees from hotel queries and air ticket queries constitute 21% and 14% respectively.

Priceline.com Incorporated (PCLN) mainly competes with Expedia, Travelocity and Orbitz in online travel services like bookings for air tickets, hotel stays and car rentals. Priceline recently released its Q4 2010 results.

Two highlights of the results are a 44.3% year over year increase in gross travel bookings, and a 68% rise in international revenues compared to same quarter last year. Rising international revenue reiterates our view that Priceline (through its acquisitions like Booking.com and Agoda) should be able to leverage its foothold in European and Asian markets.

The recession took a nasty toll on NetJets, one of Warren Buffett's holdings. While the company made a profit of $207 million in 2010, it lost $711 million the year before, Bloomberg reported.

NetJets owns a fleet of business aircraft and lets customers buy hours of flight time. With the economy picking up steam, Buffet apparently feels that demand for his aircrafts will also grow.

The first Chinese hybrid car, the F3DM, will hit U.S. showrooms next year from BYD Co. Ltd. (BYD). BYD, which stands for Build Your Dream, sold 240,000 F3DMs last year and Warren Buffet likes the company so much that Berkshire Hathaway invested $230 million in BYD in 2008. In fact, the latest BYD model will be on display at Berkshire's big meeting in May, as reported in New York Times.

BYD is a diversified energy company. In addition to its hybrid models Its products include solar panels, solar shaded parking systems, home energy storage systems and charging equipment and LED lighting. BYD plans to open showrooms in the Los Angeles area.

ArcelorMittal (MT) is currently the largest steel manufacturer in the world, formed by the merger of two steel giants, Arcelor and Mittal in 2006. The company competes with other international Steel giants like BaoSteel, Posco, Nippon Steel and ThyssenKrupp.

Our price estimate for Arcelor Mittal stands at $40.67, roughly 10% above market price.

The cotton market is in a state of chaos. On Friday, March cotton on the ICE exchange closed at $2.1102 per pound, up the 7 cent daily limit, the Financial Times reported. The market opened limit up at $2.1102. That means that you cannot buy cotton even if you wanted to. The market is frozen.

Commodities are much different from stocks. Commodities are a zero sum game. Contracts usually last for three months. At the end of the three months, the longs take delivery from the shorts who deliver their cotton, and zero contracts are left.

Economist Gary Shilling has agreed to share with BloggingStocks his 18 investment strategies for 2011, beginning with Gary Shilling's Investment Strategies for 2011. But he will only be revealing them a little at a time, over the next few weeks, so check back often!

My investment strategies for 2011 are driven by my forecasts for the economies and financial markets here and abroad. In my view, the overarching reality that will dominate 2011 and, indeed, the next decade or so is financial deleveraging, as spelled out in my new book, The Age of Deleveraging: Investment Strategies for a Decade of Slow Growth and Deflation, which was published in November 2010 by John Wiley & Sons.

Today North Dakota produces 400,000 barrels per day. With upgrades in infrastructure, production could go to 600,000 to 800,000 barrels per day.

There's a new industry in the making. It's in the way we buy and read books. Electronic books, or e-books, are taking the book market by storm. Here's a mind blowing statistic. Barnes & Noble (BKS) announced that in December its e-book sales exceeded print books, as reported in MSNMoney.
