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.

The sale of DVDs is going the way of the PC -- both have seen their market share dwindling. In a world of instant information, streaming videos are replacing DVDs. Last year, DVD sales fell by 43% to $7.8 billion from $13.7 billion in 2006, The Wall Street Journal reported.

There is another accompanying trend that reinforces streaming videos. Customers are spending more time online. Add the multiplier of time spent on social networks and it's streaming video hands down.

Google (GOOG) is ever searching for new opportunities. This time they want to enhance their YouTube site, which is noted for allowing and promoting home videos.

Google has a successful money stream called its partner program for YouTube. If you become a partner you agree to let Google place ads on your video and to let Google rent your video.

Once the master of the game, Nintendo (NTDOY) has fallen behind in the gaming industry. It reported a 46% drop in profits in its recent quarter, as reported in Reuters. Nintendo is trying to do "catch up" with rivals Apple's (AAPL) iPhone and Google's (GOOG) Android, both or which have strong gaming platforms.

Nintendo is launching the first handheld 3D gaming system without glasses later this month. Nintendo of America's president, Reggie Fils-Aime, expects that the 3DS will sell even faster than its original DS device, which sold 150 million units to date.

The mobile revolution is spawning a variety of business relationships to attract new customers. The latest is the partnership between credit card holder, American Express (AXP) and the social network Foursquare Labs Inc.

Both companies are capitalizing the growing segment of online purchasing. American Express had roughly $100 billion in online transactions last year. Online spending is growing at a 20% rate, compared to15% for overall spending, as reported in the Wall Street Journal.

DirecTV (DTV) competes with satellite pay-TV providers like Dish Network (DISH), cable companies like Comcast (CMCSA) and Time Warner Cable (TWC), and telecom operators like AT&T (T) and Verizon (VZ). The company recently released its Q4 2010 earnings and we have updated our price estimate to $48.63 as a result of continued subscriber gains and ARPU growth both in the U.S. and Latin American businesses. Our price estimate stands at a roughly 5% premium to market price.

However, we may still be conservative in our price estimate given the traction that DirecTV is getting in the Latin American region. Below we discuss some highlights of growth for DirecTV's Latin American operations and examine the potential upside to our base forecasts.

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.

It is a different kind of chip maker. Its core business is licensing chip designs to larger companies like Apple (AAPL), Samsung (SSNLF) and Qualcomm (QCOM.), as reported in the New York Times.

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.

Yahoo (YHOO), which competes with Google (GOOG) and AOL (AOL) in the search business, is seeing a relatively stable profit margin of 42% since 2008 by our estimates, and we expect the margin to rise slightly over the coming years as Yahoo benefits from its partnership with Microsoft (MSFT). In 2009, Yahoo and Microsoft signed a deal whereby Yahoo will not only use Microsoft's search technology on its websites but will also keep a majority of the ad revenues. Yahoo is also making efforts to control costs by cutting its workforce, which should improve profitability in the short term.

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.
