Time to Watch the Transportation ETFs

Even though the S&P 500 is trading with 3 percent of an all-time high there may be some troubling signs within the market. The Dow Jones Transportation Average is now 6 percent off its all-time high set in November of last year and it has struggled to break through the old high during the rallies.Because the transportation industry can be considered by many to be a leading indicator of the economy it has raised yellow flags for the bulls. In comparison the Dow Jones Industrial Average is only down 3 percent from its all-time high set in March and it continues to hold the lows of the last two months.The reason the transportation stocks are important is because the sector is responsible for moving goods around the country and the globe. If the sector begins to struggle it could be an early indication that demand for goods is starting to wane. Another bearish argument is that with oil prices less than half of where they were last year it should be a boost to such sectors as trucking, airlines, and logistics. On the flip side the low energy prices have hurt the railroads that are responsible for shipping a large portion of oil and gas around the country.The pullback of 6 percent from an all-time high is not a flat-out sell signal, however it is something to keep an eye on as earnings season gets into full swing later this month.
