Asda owner Walmart warned earnings next year would be flat and it was slowing the pace of store openings in the US (The Financial Times). The world’s largest retailer highlighted intense competition in retail across the globe as the warning put a dampener on its share price.

Mars has bought out Warren Buffett’s minority stake in its Wrigley subsidiary. The deal, in which the maker of M&Ms and Snickers bars will buy the remaining 20% in the chewing gum group held by Buffett’s Berkshire Hathaway, will solidify Mars’ leading position in the $177bn global confectionery market, writes The FT. Berkshire Hathaway acquired the holding when it went in with Mars to buy Wrigley’s for $23bn in April 2008 (The Guardian).

The shortlived drop sparked speculation that it could have been triggered by a mistaken “fat finger” trade or a rogue automated algorithm.
