"For the 24th year running that the Economist magazine has published its famed Big Mac Index; this index is a tongue-and-cheek way of measuring the purchasing power parity (PPP) -- that is, the relative overvaluation and undervaluation of the world's currencies," notes Nicholas Vardy.

The editor of The Global Stock Investor explains, "What does the Big Mac now say about the relative value of global currencies?

"According to the theory of purchasing power parity, a dollar should buy the same amount of the same good across all countries. By comparing the cost of Big Macs -- a good that is produced in about 120 countries -- the Big Mac Index calculates the exchange rate (the Big Mac PPP) that would result in hamburgers costing the same in America as they do abroad.

"I've long believed that China's currency is due to appreciate notably against the buck," says currency expert Jack Crooks, upon returning from speaking at a Forex seminar in Beijing.

In his World Currency Alert he explains, "Until now, there's been no straight-forward, highly-liquid way to play it. Now there is: the WisdomTree Chinese Yuan Fund (NYSE: CYB)."

"I now think it makes sense to secure some exposure to the Chinese yuan. There's been a major U.S.-China dynamic that's drastically altered the global economic landscape over the last several years. It goes a little something like this:

• China sends goods to the U.S.
• The U.S. sends dollars to China.
• China sends dollars back to U.S.
• The U.S. sends treasuries to China.

"Ultimately, China supplies the globe with liquidity. Behind this capital flow is an artificially undervalued Chinese yuan. This exchange rate situation is why China has become a major supplier of goods and capital to the rest of the world.
