Marmite insurance claims outsourcer Quindell Portfolio (QPP:AIM) leaps over 7% on news of robust cash collection. Average debtor days have been slashed from 6.5 months to 4.8 months, a blow to sceptics that had used ballooning debts to beat the company with this year despite several large contract wins. Shares has been a fan of the growth potential of Quindell for over a year, first flagging the shares at 5.63p in June 2012 (see page 8 of PDF), and again just days after Christmas as one of our plays for 2013.

Better-than-expected half-year results from Interserve (IRV) help sustain momentum in the share price, up 2% to 546p and extending a decent run in the weeks preceding the numbers.

Read our recent 'griller' interview with Interserve to understand why there is merit in retaining the construction arm.

Rentokil Initial's (RTO) second-quarter results are ahead of consensus forecasts, triggering a 4.7% rise in the share price to 101.6p. Yet European trading is still tough, there's no organic revenue growth and cash generation is weak.

He's being replaced by Bernie Pryor, currently a director at the Sierra Leone-based miner. Former CEO Alan Watling is back in a special advisor role. Chief financial officer Miguel Perry is retiring and will be replaced by Matthew Hird, the ex-finance boss at copper producer Kazakhmys (KAZ). The market is perplexed at African Minerals' revolving doors, the shares falling 9.5% to 220.75p.

Gold miner Centamin (CEY) falls 4.3% to 37.1p despite hitting quarterly forecasts. Ongoing troubles in Egypt are no doubt contributing to negative market sentiment.

Bank of Georgia (BGEO) jumps 4% to £18.62 after reporting record interim profits. The bank made a taxable income in the first half of the year of £37 million, a 10.5% annual improvement, driven by a 111% pre-tax profit rise in its healthcare and insurance operations. The bank also reports another record as its cost to income ratio falls to 41.7% from 45.6%. Analysts at Numis believe there is more to come. ?With continued good cost control and non-interest income growth (particularly Insurance & Healthcare), the prospect of stronger volume growth, and an improved impairment outlook we expect an improved second half performance.?

Shopping centre and retail park investor Capital & Regional (CAL) rises 6.3% to 37.5p after announcing plans to resume dividend payments, as Shares predicted earlier this month (1 Aug). This was driven by the group reducing its loan to value to 57% following several asset disposals and making a £3.7 million pre-tax profit, compared to a £9.2 million loss in July of last year. One negative is that its 52p NAV per share is down on last year?s 53p.

Chairman Naftali Shani has confirmed advanced talks to sell his 14.1% stake in the business to private investment company BGI Investments. That added to separate negotiations to get a 17.1% stake owned by Fortissimo Capital would pitch BGI over the 30% tipping point at which it would have to launch a bid for the whole company.

William Edmondson is respected by the City so the news comes as a blow, although today's 8% slump to 34p looks like an over-reaction.
