Oil prices hit a six-week low on Wednesday, as ample supplies and weak demand led to a 3.5% decrease in crude oil for October delivery. Energy prices generally followed oil down, leading to lower fuel costs for transportation companies. Ocean shippers and passenger planes rose on the news, but railroads were down.
Aviation fuel is a major expense for passenger airlines, which have shown weakness in recent months (and, in the case of legacy airlines, recent years and decades, for that matter -- it hasn't been a very profitable industry). United Continental (NYSE: UAL ) soared more than 7%, with Delta Air Lines (NYSE: DAL ) not far behind, up 4.5%. Despite today's gains, the two airlines look far from overpriced. Delta and United both sell for about 3.6 times forward earnings, roughly a quarter of the price of the S&P 500 at large.
Maritime transportation also saw big gains as prices for the bunker fuel they use, a low-quality fuel source that nonetheless constitutes the bulk of voyage expenses, dipped lower. As bunker fuel prices rose over the summer, many shippers resorted to slowing their ships down to more fuel-efficient cruising speeds to cut expenses. The industry's biggest gainer was dry-bulk goods carrier DryShips (Nasdaq: DRYS ) , up nearly 6% on Wednesday.
On the other hand, the Dow Jones Railroad Index closed the day down 1.2%. Railroads generally benefit from higher fuel prices because of their more efficient operations, making them less competitive in periods of cheap fuel. Lower demand for energy products could also translate to lower volumes shipped for coal, a major revenue generator for companies such as CSX (NYSE: CSX ) , a railroad operator concentrated in the American east that derives around 30% of revenue from shipping Appalachian coal. CSX closed down 1% on Wednesday, but after-hours trading pushed it down more than 5%.
CSX investors were spooked by rival railroad Norfolk Southern (NYSE: NSC ) , which has the second-highest exposure to coal shipments after CSX and announced Wednesday that third-quarter earnings will be below estimates. The company blamed ow freight volumes and lower revenue from fuel surcharges, but investors weren't impressed, and Norfolk Southern was down 5.5% in after-hours trading.
