Emerging markets bank Standard Chartered (STAN) advanced 1.9% to £14.37 after posting a positive second quarter update.

One low point was the confirmation that loan impairments will increase by 15% this year, mainly due to its Korean loan book.

Stagecoach (SGC) rose 3.7% to 310.7p as the market liked full-year results from the public transport group. Pre-tax profit was down to £195.8 million from £239.8 million but the dividend's gone up by 10.3%. Analysts said it is trading well despite earlier concerns about the US, supported by a healthy cash position.

Profit warnings are coming thick and fast across the tech space, today being the turn of US-focused healthcare software supplier Craneware (CRW:AIM). It needed to bag a big contract to hit year to June expectations, and while talks run on several contracts, none will be signed-off in time. Not the worst warning ever, which explains why the £87 million cap's crash is a relatively modest 12.9% to 327.5p.

Video search engine Blinkx (BLNX:AIM) fell over 7% to 117p after Hewlett Packard (HPQ:NYSE) dumped its 12.6% stake in the UK company. Market gossip puts the sale firmly down to the US tech giant's widely publicised fallout with Autonomy founder, and Blinkx director, Mike Lynch.

Small cap cruise provider All Leisure (ALLG:AIM) retreated 5.9% to 32p after saying that earlier power problems at one of its ships are taking longer to fix than originally expected.
