With gas prices in the west coast cruising past the $3 dollar mark and president Bush signing an ethanol pact between the US and Brazil its time to revisit the ethanol stocks. One and a half years later, Bill Gates purchase of convertible securities in Pacific Ethanol now stands at 100% return even with the declining of ethanol margins.
While the Brazilian ethanol industry has been successful, the same said can't be said of the US. Most US ethanol companies have been caught between a rock and a hard place. The profitability of ethanol is largely dependent on the price of politically sensitive commodities, namely corn and oil/natural gas. Unlike last year's state of the union address, this year's address failed to ignite ethanol stocks. And it is because of this that investors have to be wary about the future prospects of ethanol in the US.

With ethanol, the margin largely depends on the cost of corn from which it is made from and also the price of it's substitute, gasoline. Although natural gas prices have declined, rising corn and labor costs have been eating into the ethanol producers margins. For the pure play ethanol producers, it is hard for them to pass on their costs in the face of low gas prices. While some may have hedged their prices during last years oil spikes, it's unlikely that they will see higher margins in the near future with the talk of a slowing economy that may drive down the demand for ethanol. Whats more, the large oil companies are capable of driving down the oil prices in order to kill the competition.
Only two Midwestern grain processing firms that produce ethanol have the flexibility of switching to processing corn for human consumption thus passing on the costs to consumers. With decreasing margins Archer-Daniels-Midland and MGP Ingredients are able to use corn to produce syrup, starch, glucose, dextrose, sweeteners or beverage alcohol. The rest of the ethanol producers are thus left to the mercy of the corn farmers and oil prices.
Even with the current situation, we have certainly not seen the last of the ethanol 'boom'. The sensitivity of oil prices to natural calamities as well as political upheavals in the middle east is all that takes to drive the price of ethanol stocks. With such volatility some investors will make money while others will be left wondering what they got themselves into.
