Updates from Apple and Greene King

Updated: 
More southwards drift for the FTSE 100, down 55 points on Monday to 6,595. Fresnillo, by some margin, was the biggest faller, losing -8.76% to 760p. Randgold Resources also slipped heavily, down -4.35% to 4,157p.

The Dow Jones also lacked support, falling almost 78 points to 16,008.7, a -0.48% fall in total.

We start with news from Apple, which has snapped up social media data analytics company Topsy Labs. It's not known how much Apple paid for the company, but the Wall Street Journal estimates the figure at around £122m.

Topsy focuses on deploying Twitter data to track and index customer sentiment. It's thought the Topsy technology could be used for Apple's iTunes Radio. Earlier this year Apple paid an estimated $350m for PrimeSense, an Israeli 3D chip developer.

Apple has officially confirmed the acquisition. "Apple buys smaller technology companies from time to time, and we generally do not discuss our purposes or plans," a spokesperson told the FT.

Next, an update from Greene King for the 24 weeks to 13 October. Total revenues come in 5.2% higher at £566.2m while operating profits climb 3.7% higher to £122.7m. Adjusted basic earnings per share are up 6.3% to 30.4p.

Retail like-for-like sales are 3.5% while the retail margin increases ten basis points to 20.5%. Average EBITDA per pub is up 5.2% in Pub Partners with core like-for-like EBITDA up 1.7%.

"This is a very pleasing set of figures," says chief exec Rooney Anand, "and we have made great progress in the first half of this financial year. Growth has once again been led by our retail business, which grew profits by 8% over last year."

We end with a six month interim from Betfair. Underlying total H1 revenues slipped 6% to £188m from £200.6m. Sustainable revenues climbed 11% in Q2 and now represent 77% (H1 FY13: 71%) of total revenues claims Betfair.

The interim dividend climbs 50% to 6.0 pence per share. Betfair claims it's expecting full year underlying EBITDA of between £82m and £87m in FY14, including combined start-up losses of between £5m and £10m in Italy and New Jersey.

"We continue to see evidence," says chief exec Breon Corcoran, "that our Exchange and Sportsbook products are complementary, with 38% of sports betting customers using both products. This overlap is set to increase in the coming months following innovative developments to our bet matching technology."
