The transportation sector has been on a smooth ride this earnings season with stock prices up 1.3% (aggregate one-day stock market reaction to earnings releases) in response to earnings announcements. Total earnings of 97.7% of the sector’s total market capitalization that has been reported so far is up 24.3% on revenue growth of 9.6%. This is much better than Q2’s earnings growth of 16.1% and revenue growth of 8.5% (read: Top-Ranked Sector ETFs & Stocks to Buy Now).Earnings and revenue beat ratios of 69.2% and 84.6%, respectively, are also encouraging as most of the industry players dominating the sector managed to beat the Zacks Consensus Estimate on earnings or revenues or both.For a better understanding, let’s dig into the earnings results of some well-known industry players:Transportation Earnings in FocusThe world's largest package delivery company United Parcel Service UPS met the Zacks Consensus Estimate on earnings and beat on revenues. Earnings of $1.82 were in line with the estimate while revenues of $17.44 billion edged past the estimated $17.41 billion. For 2018, the company continues to expect earnings per share in the range of $7.03-$7.37. The Zacks Consensus Estimate at the time of earnings release was pegged at $7.25.Major railroads Norfolk Southern Corp NSC and Union Pacific UNP topped both the estimates. NSC outpaced earnings estimates by 8 cents, while earnings at UNP came ahead by 6 cents. Revenues trumped the Zacks Consensus Estimate by $43 million and $50 million, respectively. Meanwhile, Kansas City Southern (KSU) lagged on both fronts missing earnings estimate by a penny and revenue estimates by $8 million.Ryder Systems R, the leader in supply chain management and fleet management services, beat earnings estimates by a penny and revenue estimates by $47 million (see: all the Industrials ETFs here).The two largest U.S. airlines Delta Air Lines DAL and United Continental UAL reported mixed results. This is because Delta topped earnings estimate by 6 cents while lagged on revenue estimates by $4 million. On the other hand, United Continental missed on earnings by 3 cents but beat on revenue estimates by $35 million.Last but not the least, earnings of the leading trucking carrier J.B. Hunt JBHT also came in above the Zacks Consensus Estimate by 7 cents. Revenues of $2.21 billion beat the consensus estimate by $4 million.ETFs in FocusDespite strong results, a broad market sell-off took the sheen from transport ETFs over the past month.
