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.

Bond money managers are usually glum. Then again, they need to be cautious since they are locking up money at fixed rate of returns. In a volatile world, this can certainly be a risky proposition.

So it should be no surprise that the biggest bond money manager, Bill Gross, is not enthusiastic about 2011. He leads the Pacific Investment Management Co., which has $1.2 trillion under management.

The news on the import/export front is not good. The Commerce Department reported that our trade deficit widened to $49.90 billion in July, a 21-month high. Economists surveyed by the Wall Street Journal had expected the deficit to come in at $42.7 billion.

The wider deficit was caused by a increased imports and a drop in exports. Exports shrank by 1.3% to $150.45 billion, while imports jumped to 3.1% to $200.35 billion, up from $194.42 billion.

There are many places that Warren Buffett may choose to invest Berkshire Hathaway (BRK.A / BRK.B) capital. At the same time you can be sure there are places he will not set foot. It is not likely he will invest anywhere that does not have a vibrant, well-established stock market with a stable government. So, Mr. Hugo Chavez in Venezuela will not likely see any capital deployed from the likes of "my pal Warren" any time soon.

As a matter of fact, I would put the chances at slim of any South American country, besides Brazil, getting a look at all. Brazil is just too big and too vibrant to ignore. I would rule out Africa entirely except for indirect investments in oil and minerals through large conglomerates. The closest thing in the region would be Israel, at the furthest western reaches of Asia. He has already invested there and there is a high probability he would again. Investors from most of Europe and Asia have done the same, although many would rather not discuss it.

He has also invested in China, Great Britain, South Korea, and Switzerland. I would expect more money to be plowed into all of them again without reservation if the right deal materialized.

Happy Cinco de Mayo!

In celebration of the holiday, I thought it would be nice to remind investors not to forget about the opportunities in our southern neighbor. While Mexico is not a red hot emerging market like China or Brazil, there are still profits to be had there if you know where to look.

Here's why:

This post is part of a special report, Top Picks for 2010, the 27th annual survey in which TheStockAdvisors.com asks the nation's leading advisors for their single favorite stock for the new year. See all 80 stocks listed here.

Energy sector expert Elliott Gue turns to Weatherford International (WFT) as his top pick for the coming year.

In his The Energy Strategist, he explains, "As with most oil services firms, Weatherford's North American business has been hit hard and the stock now trades at a deeply discounted valuation."

American businesses are setting up shop in Mexico instead of China. China, which was the number one location for manufacture of goods bound for the U.S., has fallen into third place. Mexico is now number one, followed by India.

Several factors have converged to make Mexico an attractive place for manufacture. Daniel Silva of the Mission Economic Development Authority said: "Compared to China, Mexico offers better access to North American markets with a shorter, faster and cheaper transportation route to move products and supplies by truck, rather than over thousands of miles by ship, rail and truck combined."

What is lithium? It is a soft, silver-white metal that is a good conductor of both heat and electricity. Because of these properties, lithium is used in the manufacture of lithium-ion batteries. Lithium batteries generate 3 volts of electricity, compared to 1.5 volts for lead/acid or zinc cells.

Lithium is used primarily in the manufacture of car batteries for hybrid cars. These cars are becoming more popular, with the major domestic and foreign car makers using lithium batteries. Hence, lithium has become a highly sought-after commodity.

Mexican President Felipe Calderon is urging lawmakers in his country and in Brazil to consider a free-trade agreement between the Latin American giants, Bloomberg News reported.

If it's approved, this would be no small economic development. First, the pact would further diversify Mexico's trade base: currently, 80% of Mexico's exports go to the United States. Second, and perhaps even more significant, the action would create spin-off commerce in each country. Typically, when free trade pacts are passed, they lead to increases in GDP and in aggregate demand, which leads to new businesses.

According to an Associated Press article citing the U.S. Justice Department, U.S. refineries purchased millions of dollars worth of oil that was stolen from Mexican government pipelines.

Apparently, the oil was stolen from the pipelines and then smuggled across the border, an illegal operation led by Mexican drug cartels that are looking to branch out. Wow, from cocaine to oil ... which of these is the most addictive. Apparently, these drug gangs hit remote pipelines and siphon off quite a bit of oil.

Like oil, sugar is an international commodity. Unlike oil, sugar is an agricultural crop dependent on the weather. This year has seen droughts in some parts of the world and wetter than normal weather in other parts of the world where sugar is grown. Both extremes affect the growth of sugar cane.

Here are some reports from various sugar-growing countries:

• India is both the largest exporter and importer of sugar. This year India will be an importer of sugar. India's inventories will fall 50% to 4.54 million tons, equal to three months consumption. Reports from farmers indicate that plants are only one foot high compared with normal growth of five feet. Rainfall was 64% below normal in the growing regions. To fill the gap, the Indian government is extending duty free imports.

How do we know that world trade is loosening up? One indication is the U.S. trade deficit. Unfortunately the U.S. has been running a growing trade deficit for the past two months. You may be asking, what causes our trade deficit? The U.S. trade deficit is caused by importing more goods than we export. In April the trade gap widened by 2.4% from March to $29.2 billion. This follows a 10-year low in February.

The trade gap narrowed by 53% from a year ago when world trade collapsed from the global recession. The slight gains in the past two months indicate that some improvement is occurring in world commerce.

Carnival Corp (NYSE: CCL - option chain) shares are rising today after the company announced this morning that it will resume stops at Mexican ports now that health officials have lifted advisories against non-essential travel to the nation.

CCL also said the H1N1 Influenza scare will likely reduce second-quarter earnings by 5 cents per share. While that isn't a good thing, investors often prefer to know how bad the news instead of having to guess. If you think that the stock won't fall by too much in the coming months, then now could be a good time to look at a bullish hedged trade on CCL.

CCL opened this morning at $26.18. So far today the stock has hit a low of $25.81 and a high of $26.60. As of 11:35, CCL is trading at $26.41 up 1.41 (5.6%). The chart for CCL looks bearish and S&P gives CCL a negative 2 STARS (out of 5) sell ranking.

Burger King (NYSE: BKC), a fast-food joint that competes with McDonald's (NYSE: MCD), Yum! Brands (NYSE: YUM), and Wendy's/Arby's Group (NYSE: WEN), issued its Q3 report on Wednesday. The top line didn't do much, rising only 1% in the face of difficulties with currency translations. Earnings came in at 34 cents per share. That was one penny better than Wall Street's expectations, according to Reuters.

It's always good to beat the earnings call. But Burger King didn't get much mileage out of that victory. The stock actually sold off 3% on the news, closing yesterday at a fresh 52-week low of $16.55. The big catalyst was the conservative fiscal-year guidance.

Late Tuesday, Carnival Corporation (NYSE: CCL) reported that it will temporarily cancel all stops in Mexico due to fears surrounding the swine flu. "We have decided to cancel calls at Mexican ports for all current sailings. Additionally, we will cancel calls in Mexico for all voyages departing Thursday, April 30 through Monday, May 4," the cruise line operator said in a statement.

Carnival isn't the only cruise line playing it safe. Sector peer Royal Caribbean Cruises Ltd. (NYSE: RCL) also announced plans to temporarily suspend port calls in Mexico. Currently, the World Health Organization (WHO) has not recommended any travel restrictions to halt the swine flu's spread.
