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:

Another Corny ETF

Published 10/12/2010 11:10 AM EDT

Last Friday agriculture ETFs such as

PowerShares DB Agriculture

(DBA) - Get Report

and

Teucrium Corn Fund ETV

(CORN) - Get Report

traded at premiums after the

USDA cut corn and soybean production expectations and the price of these commodities jumped.

The impact of reduced corn production, however, will extend beyond just commodity traders and corn-focused ETFs. Cattle prices have also been surging as farmers remain reluctant to buy more cows when the price of corn keeps rising. According to

Bloomberg

, "Meat prices are poised to extend a 14% rally this year that drove U.S. retail costs to the highest levels since the 1980s as surging corn futures prevent livestock producers from expanding their herds."

Fortunately, ETF investors have a number of ways to gain exposure to the increasing price of cattle in the short term. DBA offers exposure to both live cattle and feeder cattle contracts, but investors looking for a purer play on cattle prices can check out the

iPath Dow Jones-UBS Livestock TR Sub-Index ETN

(COW) - Get Report

. While COW is still a relatively small fund -- it has $70 million in assets under management and an average daily trading volume of 42,000 shares -- contentious, sophisticated investors should consider the unique exposure it provides. Careful trading, knowledge of ETN risks and active monitoring would all be required to trade COW successfully.

If investors do feel like they have the time and knowledge to monitor COW, the payoff could be substantial in the months ahead. While corn prices are surging right now, cattle prices won't be far behind. For investors who want to avoid the risks of an ETN and skirt the inherent volatility of single-commodity funds, DBA is still a solid longer-term bet.

At the time of publication, Dion Money Management was long DBA.

Natural Gas ETF Heats Up

Published 10/12/2010 7:03 AM EDT

Exchange-traded fund investors should look to the promise of the equity-backed

First Trust Natural Gas ETF

(FCG) - Get Report

as weather in the U.S. cools and a series of deals and acquisitions heats up the sector.

FCG recently rebalanced its underlying portfolio to restore and enforce the fund's equal-weighting strategy. After

Exxon Mobil

(XOM) - Get Report

acquired

XTO Energy

, FCG's portfolio seemed out of whack as balance in the underlying holdings initially reflected the impact of XOM's acquisition making the portfolio, temporarily at least, overweight in XOM. Now that FCG has been rebalanced, top components like

Stone Energy

(SGY)

and

Comstock Resources

(CRK) - Get Report

are playing a larger, more balanced role in the underlying portfolio.

Another notable top holding in FCG's portfolio is

Chesapeake

(CHK) - Get Report

, a U.S. firm that Chinese state-run energy giant

Cnooc

(CEO) - Get Report

has taken a stake. Between Exxon and Cnooc, the purchase of shale properties is a hard-to-miss trend. Obviously, these energy giants believe that shale investments will pay off in the long run and the now-cheap fuel will be the future of energy.

Rather than taking a back seat and watching energy from afar, use FCG to make an early investment in the future of natural gas.

While investors have been complaining about low natural gas prices, the equity-backed FCG actually has gained more than 8% in the last 30 days, so upward momentum already has begun.

A Short-Term Golden Opportunity

Published10/11/2010 11:05 AM EDT

Gold is drifting lower on this quiet Monday morning, leaving some investors scratching their heads. Isn't gold supposed to be unstoppable? In the last few months, this has seemed to be true. In the three-month period ending Oct. 8, the physically-backed

SPDR Gold Shares ETF

(GLD) - Get Report

and

iShares Comex Gold ETF

(IAU) - Get Report

and the equity-backed

Market Vectors Gold Miners ETF

(GDX) - Get Report

, have jumped 12.33%, 12.27% and 16.04%, respectively.

U.S. stimulus, inflation fears, concerns about Europe's debt and broader concerns about economic recovery have all helped to egg on gold prices, and all of these issues will likely continue to spur gold in the month ahead.

With so many investors viewing gold as a "sure bet", it can be difficult for owners of funds like GLD, IAU and GDX to tolerate days when the precious commodity tumbles. On some days, like today, the movement is difficult to explain. It's important to remember, however, that all short-term commodity trading is difficult to predict and that gold investments are notoriously difficult to time.

If you're a longer-term investor watching your gold position, I'd encourage you to keep holding at this point in time and avoid giving in to that itchy trigger finger. As the November elections draw near and uncertainty continues to permeate markets, gold should continue to move upward. Shorter-term investors bullish on gold might even use the slight weakness today to gain exposure to the equity-backed GDX.

At the time of publication, Dion Money Management was long IAU.
