Editor's note: The following are questions received from viewers of "Mad Money," seen every day at 6 p.m. EST on CNBC.

How can Carrizo (CRZO) - Get Reportbe the best natural gas play in the market? It has a P/E ratio of 39, and Chesapeake Energy (CHK) - Get Report trades at just 7 times earnings.-- Trevor from Texas

Jim Cramer

: Chesapeake is also a good company, but the point here is that there's more than one way to analyze a stock. I believe that Carrizo's value lies in how much natural gas it can potentially extract from the ground.

What percentage of my overall portfolio should be invested in international stocks?-- Rick from Minnesota

Jim Cramer

: Since most Americans have zero international exposure, I suggest that everyone start off by trying to diversify your holdings by having at least 10% of your investments overseas. That said, I believe there's more potential for growth in the emerging markets than in the U.S. in the foreseeable future. With that in mind, more nimble investors may consider bumping that number up to 20% to 25%, for the time being.
