Commodities will give companies and their investors a wild ride, even when they're so-called "specialty" commodities like the cobalt sold by OM Group (NYSE:OMG). So while this company seems to be taking many of the right steps to build a better, stronger business over the long haul, the road directly in front of it could still be full of potholes and quicksand.

Even though the company warned us about this quarter not so long ago, it still hurt. Sales dropped about 22%, gross profits fell 59%, and operating profits dropped about 57%. It's true that there were several items impacting results in both this quarter and the year-ago period, but the basic fact remains that it was a tough end to a tough year.

Both the cobalt and nickel businesses saw rough quarters because of lower prices. In cobalt, a price drop of nearly one-third per pound mitigated growth in refining volume, and operating income fell notably. In nickel, it was more of a one-two punch, as both pricing and volume trailed year-ago levels. In nickel's case, it looks like uncertainty in the stainless steel market was at least partially to blame for the lower volume produced.

It'll be interesting to watch this company over the next year or two. Its relatively new management team will attempt to improve free cash flow, and turn OM Group into more of a specialty materials/chemicals business and less of a nickel-and-cobalt company. Today's announcement of the purchase of a small Singapore-based chemicals company is just a small part of what could be a much larger effort to transform the company over time.

I think there's a case to be made that OM Group is undervalued relative to others like Inco (NYSE:N) or Engelhard (NYSE:EC). But it's equally true that some of the discount is warranted. OM Group certainly doesn't have Inco's advantages of scale, nor Engelhard's well-developed specialty businesses. Since there aren't tremendously large expectations here just yet, aggressive investors still might want to hang around to see whether OM Group really can turn itself around in the coming years.
