The market is currently up, with the Nasdaq climbing 0.9%, the S&P 500 increasing 0.5% and the Dow up 0.2%. The transportation sector is a category of stocks relating to the transportation of goods or customers. It is made up of airlines, railroads and trucking companies. The performance of the transportation sector is sensitive to the price of oil. Because operations revolve around the use of vehicles, fuel prices represent a significant cost to transportation companies. As the price of oil rises, transportation companies will be expected to earn less. Inversely, these companies do well when the cost of fuel decreases.
