Carlos Slim, America Movil's (AMX) largest shareholder, became the world's richest man in part from his investments in wireless phone service. His empire spans 18 countries and has 200 million subscribers.

Let's look at America Movil's spectacular growth. The company's markets are primarily in Latin America. American Movil controls 74% of wireless service in Mexico under its Telcel brand, which has 60 million subscribers. Brazil is second with 45 million subscribers. It also is the largest provider in the Caribbean with four million users.

With several major developments occurring around the world, many investors may wonder how they could affect their portfolios or their lives. Here are two of the current, newsworthy events and how investors may interpret them.

Libya

The oil from Libya totaled about 2 million barrels a day before the revolution, half of which was exported. About 1 million barrels a day are no longer available to the world. That isn't enough to really affect the price of oil for a long period of time. Plenty of other countries can supply that amount without straining their capacity. But they're unlikely to step in to fill the gap when oil prices are above $100 a barrel. That price should recede once the conflict finishes and a more stable government is in place.

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 Dow broke 12,000 today. What's next? Again we have those who say the glass is half full and those who say it is half empty.

Traders believe that the glass is half full. Dow 12,000 is only a number, although a psychological number. Round numbers catch the public's attention. There will be sellers screaming 'get me out' if they have recouped their losses. The market probably will absorb the half empty guys and march upward. That may not be a straight line, but the momentum is strong enough to push higher.

Warren Buffett is one of the few investors in the world that has consistently succeeded where others failed. Part of his success is due to his common sense approach to the stock market. Investors have mocked Buffett for his old fashioned approach to investing when he sat out the dot com era bubble. But Buffett had the last laugh when others lost out during the bust.

Buffett also managed to largely avoid the major losses investors faced when they invested in securities dependent on subprime lending practices. In fact, he managed to profit from it.

Here are some principles Warren Buffett follows and investors would be wise to model:

In the buyout corner of the private equity business, "dry powder" continued to grow in 2009. Industry slang for capital available for investment, this measure points to how much activity private equity funds are capable of completing.

From December 2004 through December 2008, according to data from alternative investment research firm Preqin, the amount of funds on the sidelines surged from $178 billion to $501 billion for the buyout sector, nearly tripling. This year, buyout dry powder only increased by $3 billion, to $504.28 billion. While this may feel like little more than a rounding error, it suggests stability in the sector after what has been a trying climate for financial services business of all types.

I've written previously about how, like the rest of us, the hedge fund gurus are quickly seeing their returns, assets, and now, even freedoms evaporate. Dealbook reports today that the founder of the Bayou family of hedge funds was sentenced to more than four years in prison Tuesday for a scheme to defraud investors.

James G. Marquez was sentenced to 51 months in prison, to be followed by two years of supervised release. He also was ordered to pay nearly $6.26 million in restitution.

Ouch.

His scheme involved inducing "investors to contribute to funds by misrepresenting that the money-losing funds were highly profitable."

While identify theft is a huge global problem, it is also a big market opportunity. Take a look at TrustedID, which develops protection solutions.

This week the company announced a $10 million round of venture capital. Its investors include Opus Capital and Draper Fisher Jurvetson.

"Our funding process went quickly and smoothly," TrustedID CEO and co-founder Scott Mitic said in a BloggingStocks interview. "The investment community likes companies with proven market demand, strong revenue growth, reasonable customer acquisition costs and a great ability to retain customers for years."

TrustedID has a unique product called IDFreeze, which actually stops ID theft before it happens. There is even a $1 million guarantee.

"ID theft is definitely getting more pervasive and more complex," said Mitic. "As with many maturing crimes, we're seeing the problem morph and change. The majority of crimes are still focused on credit-based identity theft, but those crimes are getting more aggressive and starting to target new victims – children, for example. We're also seeing growth in non-credit based identity theft – for example employment-oriented identity theft which involves the theft of SSNs for use in employment by non-documented workers."

Yes, it's scary stuff. But, at the same time, it's propelling the business at TrustedID. "We're seeing great month-to-month customer growth and revenue growth," said Mitic.

In the musical Fiddler on the Roof, Reb Tevye laments in the opening line of "If I Were a Rich Man" that "It's no shame to be poor. But it's no great honor either!"

The image of the poor peasant is so powerful that when people come into even a small windfall, they start to think of Tevye, which is a pity because he's offering bad financial advice. In fact, the last thing that anyone should do if they come into extra money is to break out into song.

Of course, the odds of Tevye or anyone else striking it rich are tiny but many people do get windfalls from an inheritance that's neither as generous nor as wacky as those outlined in this story. More commonly, people get extra money from investments including stocks and real estate.

Though everyone's situation is different, there are a couple of principles that people with extra cash on their hands should consider.

Rule number one is not to act like you've won the lottery. You shouldn't act that way even if you hit the latest Power Ball jackpot. That saying about a fool and his money being soon parted is true. Remember spending yourself into huge amounts of debt is easy. Just ask Michael Jackson.

The best investment for most people is themselves. Pay off any high-interest credit card debt if you have it. Get additional training or education if you need it. If there's still money after those expenses, then consult with either a tax or financial planning professional about your situation. If possible, do this before you get the money so you can plan ahead.

Investment ideas were aplenty, following up on our Ira W. Sohn Investment Research Conference blog earlier. Some ideas worth noting are:

• Bill Miller, despite being wrong on this investment since 1999, believes Eastman Kodak Company (NYSE: EK) will turnaround and is worth $45 per. As we have blogged in the past, the new CEO is very close to getting this business model to work, meaning this company could turn into a free cash flow machine.
• Steve Mandel, formerly of Tiger Management and now running a fund at Lone Pine Capital, likes EMC Corporation (NYSE: EMC), which was up big last week. In addition, he likes other large cap stocks such as General Electric Company (NYSE: GE) and Goldman Sachs Group Inc (NYSE: GS). He also has has postive comments on Google Inc (NASDAQ: GOOG).
• Wilbur Ross is still pushing his commodities turnaround plays, in particular International Coal Group Inc (NYSE: ICO). Ross's thinking is as follows: Coal pricing should reach healthy levels as excess inventory is burned off. Coal will account for 57% of U.S. electricity generation, up from 50% today, in the next twenty five years. Appalachian coal, in which ICO is rich, has considerable pricing power since East Coast supply is limited and demand is strong.

The ideas were aplenty with some negative views on MBIA Incorporated (NYSE: MBI), betting against subprime mortgage exposure, and The St. Joe Company (NYSE: JOE), the northwestern Florida real estate company, which is running into some difficulty as the housing market slowdown continues.

Rare is the day that a Wall Street analyst -- or a financial planner for that matter -- will recommend buying and holding a stock for a decade, or even longer.

The U.S. and international economic cycles, changing circumstances in a sector, operational changes in a company, and the continual change that characterizes the dawn of the globalization era, all point toward holding a stock for a considerably shorter period -- buying a stock, and then selling it at its short-term peak, however one would define that short-term period.

Still, in this space The Fly has outlined several rare exceptions, hopefully supported by enduring fundamental, macroeconomic, and technical data/reasons for maintaining the position long-term. The 3 members of that elite club described to-date: General Electric (NYSE:GE), Sears Holdings (NYSE:SHLD), and United Technologies (NYSE:UTX).

Well, add AT&T (NYSE:T) to that list.

AT&T has more than 70 million landlines, one of the biggest mobile phone systems in Cingular Wireless, an enormous geographical footprint, an emerging digital satellite TV service via Echostar's (NASDAQ:DISH) network, and, perhaps most overlooked, a broadband service.

Everyone knows that sex sells. That does not take much convincing. Why? Because we have a built-in mechanism that compels us every day, and through every week, month and year to at least take notice. The word in the blog title is a case in point. It probably piqued your interest in reading this, and I took advantage of that. Year in and year out sex sells. Well, the same can be said about stock dividends.

Dividends assure some return on your investment day by day, year after year, in up and down markets. The compounding of these dividends over time adds a burst of upside that is significant in the long run and this has been well documented. The Motley Fool talks about how dividends are powerful and that Wharton finance guru Jeremy Siegel agrees.

So following up on the importance of making a return on capital investments I thought I would add another historic consideration in value investing with a personal example. In my Roth IRA I am conducting a non-scientific experiment.
