HSBC analyst Charlene Liu lowered the firm's price target on Baidu to $145 from $157 and keeps a Buy rating on the shares following the company's developer conference. The firm says Baidu's advertising outlook remains more challenging than it expected. It cut estimates on weaker a macro envinrment.

JPMorgan raised the firm's price target on Barclays to 240 GBp from 220 GBp and keeps an Overweight rating on the shares.

As previously reported, Wolfe Research initiated coverage of Kirby with an Outperform rating and $126 price target. Kirby, the largest domestic tank barge operator in the U.S., has outperformed materially over the past year, but the firm sees more upside ahead with visibility to continued barge industry capacity constraints and strong pricing power the next few years, the analyst tells investors. In contrast to over-capacity challenges and pricing headwinds across most other transport sub-sectors right now, the multi-year supply/demand outlook for the barge industry has "arguably never been better," the analyst added.
