Jim Cramer struck a mostly constructive tone in CNBC's "Mad Money" lightning round, reiterating that Uber is a "great long-term" buy as the company and drone-delivery company Zipline announced a strategic partnership to expand autonomous delivery across the U.S. He also recommended Tanger, citing a price target increase to $46 from $45 on a stock trading around $38 and a 3.25% yield after the outlet-center REIT reported better-than-expected second-quarter results on Aug. 4. Rockwell Automation also drew a positive long-term view, with Cramer saying the company is more exposed to robotics than data centers and worth buying gradually; the company reported third-quarter adjusted earnings of $3.49 per share on Aug. 4, above estimates, on revenue of $2.313 billion. He said profitable Neurocrine Biosciences was "fine," while Morgan Stanley analyst Jeffrey Hung lowered his price target to $182 from $196 and maintained an Equal-Weight rating on Aug. 13. Cramer also said he would not argue with Amcor at 10 times earnings despite its slower-growth mix, after the packaging company posted better-than-expected fourth-quarter earnings on Aug. 12.
