NEW YORK ( TheStreet) -- When I travel back and forth between Tampa Bay and the New York City area, I keep an eye on the number of trucks on the highways and like to stop along the way where the truckers do, TravelCenters of America ( TA). During my last trip in mid-August, I wrote Buy TravelCenters as the Economy Improves.TravelCenters ($8) had a strong buy rating when I thought the stock had some upside for a buy-and-trade strategy as a proxy for the transportation sector, where 72.4% of the 181 stocks are rated sell or strong sell. TravelCenters stock closed at $7.57 on Aug. 13 and continued to move sideways to down to $7.35 on Aug. 27. The stock is in the retail-wholesale sector and is now rated buy according to ValuEngine. The 12-month forward price-to-earnings ratio remains at 7.8, and the stock trades at 71% of its book value. The stock tested its 200-day simple moving average at $8.57 on Tuesday, up about 16% off the recent low. ValuEngine one-year price target is $8.60. My semiannual value level is $7.18 with a quarterly pivot, now a magnet at $8.04 and my semiannual risky level at $9.32. Today I am profiling 14 stocks in the trucking industry. One is rated a strong buy, one is rated hold and 12 are rated sell. Only two are undervalued and eight are overvalued by more than 20%. Nine have gained more than 40% over the last 12 months with three of these up between 124.2% and 228.1%. Twelve-month trailing P/E ratios are elevated between 16 and 26.8. Thirteen are above their 200-day simple moving averages reflecting the risk of reversion to the mean.
