Today's biggest winners and losers in the stock market.

On this episode of Stock Movers:

- Barclays shares dropped the most in more than a year after its second-quarter earnings showed US consumer banking and investment bank growth had not matched up to the pace set by larger American rivals.

- Mercedes shares rise after the carmaker reported resilient profits that beat expectations even as deliveries fell due to a slump in China, where a prolonged property downturn is eroding consumer sentiment.

- Man Group shares rise as much as 9%, a 16 year high, after the company’s assets jumped to a record in the first half of the year as clients poured money into the firm’s long-only investment strategies and strong performance gains helped drive growth.
