Corn prices have risen about 22 percent over the last month and still have room to grow, while oil and gold are due to retreat in the near future, says Michael Gurka, managing director of Spectrum Asset Management in Chicago.

Hot, dry weather patterns have sent corn prices rising on supply concerns, and despite recent gains, prices are poised to grow even more, while gold and oil are poised to fall.

"There's potentially going to be a short squeeze here in metals and energy — gold and crude," says Gurka, according to CNBC.

"If you start seeing crude getting above $93 to $95, that's when you're going to start seeing some pretty good short positions coming in. For gold, $1,625 and north of there, it's mostly the same scenario."

Gold is currently trading around $1,615 an ounce while oil is trading around $87 a barrel.

Corn futures for July delivery are trading around $7.02 a bushel.

Others see more gains in store for corn.

"We see little in the near-term (apart from a dramatic shift in weather patterns in the coming weeks) that will cull the market’s current bull run," Morgan Stanley analyst Hussein Allidina writes in an outlook for clients, CNBC adds.

A Reuters poll of analysts predicts the U.S. corn yield to come in 5.4 percent lower than the U.S. Agriculture Department forecast.

"We are losing production on a daily basis," Jefferies Bache grains analyst Shawn McCambridge says, according to Reuters.

"We have 100-degree (Fahrenheit) temperatures (38 degrees Celsius) and very little rainfall, and it looks like the extended forecast is more of the same."
