Forward Air Corporation (NASDAQ: FWRD) provides time-definite surface transportation and related logistics services to the North American deferred air freight market. The firm typically receives freight that has been transported by plane, sends it to a sorting facility, then dispatches it by truck to a terminal near its destination. Forward Air operates through a network of 85 terminals near major airports in the United States and Canada, contracting to cargo airlines and air freight forwarders.

The company surprised the Street last week, when it reported Q4 EPS of 43 cents and revenues of $114.5 million. Analysts had been looking for 38 cents and $104.8 million. Management also guided Q1 EPS to 32-36 cents (33 cent consensus). William Blair subsequently upgraded the issue to "outperform".

Just last week, Forward Air Corp. (NASDAQ: FWRD) announced its results for the second quarter, which saw revenues climb by about 7%, while net income dropped almost 12%. The company blamed increasing expenses and an uncertain freighting climate, but the Street blamed the company as shares dropped around 10%.

It was the second quarter in a row where revenues were up but profits down compared to the respective quarter of 2006, so I'm not surprised investors have been staying away. But Bear Stearns upgraded the company last week, and I think it was right to do so, especially heading into the holiday season. If you look at FWRD's stock price over the past few years you can see it jump in the early autumn of each year: It seems investors like to buy at that time in anticipation of holiday shipping revenues.

MOST NOTEWORTHY: Roche Holdings AG (RHHBY), US Steel Corp (X) and Penn National Gaming (PENN) topped today's list of most notable downgrades:

OTHER DOWNGRADES:
