It’s time to buy shares in FedEx and United Parcel Service, which are attractive opportunities for investors after their shares tumbled recently, according to Credit Suisse. Analyst Ariel Rosa reiterated its better ratings than FedEx and UPS, while starting to cover 18 transportation and logistics companies. The analyst focuses on quality companies with strong management teams and solid balance sheets, according to a note on Monday. “We see many trucking companies with strong fundamentals to support their pricing, which are less dependent on bullish narratives than in other parts of the market,” writes Rosa. “We believe current valuations offer compelling opportunities for investors with a long-term perspective.” FedEx shares may be down more than 20% from their peak, but Rosa said a new CEO focused on improving margins could lift the stock. In recent years, FedEx has struggled with profitability in its Ground business, as well as fully integrating its acquisition of TNT Express in 2016. Rosa writes: “While FDX faces challenges Because of its operational uncertainty, we consider its current valuation to be too cheap given its indispensable role in the global logistics sector.” “We see upside potential for consensus EPS as FDX shifts focus to revenue quality and closes in on the integration of TNT Express, which should help boost margins.” The analyst raised the company’s 12-month price target from $294 to $314. The new target represents a roughly 30% gain from Monday’s close. Shares of UPS are “attractive” after falling 22% from their peak, according to Credit Suisse. The analyst believes UPS is a “best in class” business with a high dividend yield and “outstanding” profit margins, even as there are some concerns surrounding its exposure to Amazon. “While we harbor some concerns about exposure to Amazon’s largest customer, Amazon, we generally believe that this risk is exaggerated and largely overvalued,” the note read. “We believe that UPS’s discount to the broader market underestimates the strength of its core business and the difficulty of scaling the network in terms of scale and services.” The analyst has slightly lowered the 12-month UPS price target from $226 to $225. The new target is still about 24% above the company’s Monday close. Shares of FedEx were up nearly 1% in pre-market trading Tuesday. UPS has been shut down. — Michael Bloom of CNBC contributed to this report.
