NEW YORK ( TheStreet) -- Don Dion posts his current insights on the stock, bond, commodity and currency markets in his RealMoney blog, anticipating which ETFs will be in play next.

Here are three of his blog posts from the past week:

The Corn Is High

Published 6/9/2011 5:15 p.m. EDT

Corn: the golden commodity you can eat. Apparently I wasn't the only investor who thought about turning to the Teucrium Corn Fund ( CORN) today after reading the latest notes from the Department of Agriculture: More than 324,000 shares of CORN crossed the tape today, three times the three-month average daily trading volume.

I've been bullish on corn since late April, as foul weather and subsequent delays in planting began to create an inevitable bottleneck in the corn market. While CORN offers corn-specific exposure, I've always contended that the ETF's single-commodity-specific risk can make its short-term gyrations intolerable for more conservative investors. The PowerShares DB Agriculture ETF ( DBA) is a more diversified fund that offers corn exposure among its variety of crop-related holdings.

The corn crunch isn't over, however, and I expect to see a boom in the trading of CORN in the weeks ahead. Just as the Market Vectors Egypt ETF ( EGPT) took center stage as protesters unseated a tyrannical leader, CORN should see an influx of investor interest as the global market lurches to gain exposure to the bottleneck in corn markets.

Unlike the sudden explosion of a drilling platform or sudden, catastrophic fires in agricultural centers, the corn debacle has been visible for some months now. Since it takes time to plant, grow, harvest and transport corn, delays in planting will have a domino effect on the rest of the process, and panic could push prices even higher.

Right now, corn might not sound like the most exciting commodity to watch, but keep an eye out in the sessions ahead. Let's hope that the popping price of corn, and subsequent speculation about corn prices, don't create an unreasonable bubble in the CORN fund.
