When government boosts its involvement in the economy, there's a predictable impact on interest rates, taxes, inflation, the country's currency and even its stock market. As a veteran global investor, I've seen this play out time and again in emerging-market economies, where it's commonplace for government to play an active and heavy-handed role.

I know from my years of experience just what to expect each and every time this story plays out. And that's not all.

I also know how to turn this special knowledge into beat-the-market profits.

Here in the United States, the Obama administration and the U.S. Federal Reserve are like two elephants that have been put to work brutishly reshaping the U.S. economy. We're already experiencing the effects of big government involving itself in the private sector. Expect the dollar to fall even more - after year-end profit-taking ends. Also expect a further deployment of government-stimulus money to industries where the United States has a large competitive advantage and can generate domestic jobs.

We'll be only too happy to ride the resulting economic shifts for profit.

In fact, as part of this installment of "Buy, Sell or Hold" - I've identified three of the best profit opportunities for the New Year. The three "must-own" companies - each poised to benefit from these shifts - are: Corning Inc. (NYSE: GLW), The Boeing Co. (NYSE: BA) and Cypress Semiconductor Corp. (NYSE: CY). We offer them to you here as part of a Money Morning "Outlook 2010" Special Report.
