ARM falls as FTSE 100 treads water The wider market experienced rather less dramatic moves this morning. It was a flat start for the FTSE 100, which was little changed at 6,109, while the mid-cap FTSE 250 added 30 points to 12,789. Although the troubles at HMV cast a cloud over the retail sector, luxury goods group Burberry was climbing higher on the back of its Christmas trading update. "A bright spot for retailers this morning however is the turnaround in Burberry which only a few months ago had issued a profits warning following slowing Chinese sales," said Angus Campbell, head of market analysis at Capital Spreads. The stock market adage is that profit warnings come in threes, but it would seem not for Burberry which saw its share price plunge to a low of around £10 in 2012 and is now back above £14. The FTSE 100 group posted third-quarter sales that beat market expectations, and investors chased the shares 4.5pc higher this morning. Meanwhile, online grocery group Ocado also provided some cheer. The company said gross sales for the six trading weeks to January 6 climbed 14.2pc, sending its shares up 2.9pc on the FTSE 250.
