Below are some of the main news-driven share price changes shortly before the close.
RISERS
Obtala Resources Limited (LON:OBT), up 16%. Hot on the heels of yesterday's board changes, Valentin Bovykin has emerged as a major shareholder in the Africa-focused holding company, with 7.7% of the shares.
Plexus Holdings PLC (LON:POS), up 9.2%. It is not often shares rise on a fund-raising but Plexus advanced to 62.95p after it raised US$5mln by selling shares at 52.05p a throw.
Mirada PLC (LON:MIRA), up 8.6%. Shares in digital TV firm Mirada surged in London on Tuesday as it signed reseller agreements for India and Latin America, which complement its expansion plans.
FALLERS
TomCo Energy Plc (LON:TOM), down 13%. The company is asking for shareholders to vote on a share capital reorganisation at its annual general meeting (AGM) so it can, should it wish, issue new shares to raise money.
RedT Energy PLC (LON:RED), down 10%. Full-year results from the energy storage technology company failed to please, even though it moved back into the black.
Futura Medical PLC (LON:FUM), down 9.6%. It's a tough crowd for Future; all the company did was announce the date of its AGM and the shares lost around one-tenth of their value.
Below are some of the main news-driven share price changes at 1.15pm.
RISERS
Standard Chartered PLC (LON:STAN), up 14%. The emerging markets-focused bank moved back into profit in the first quarter. “Overall trading was described by management as being in line with its expectations, but we think credit quality and capital ratios are better than the market will have expected and so are not surprised to see the shares react positively,” said Shore Capital Markets.
Aurasian Minerals PLC (LON:AUM), up 13%. The company proposes to raise £163,400 by way of a subscription issue of shares at 0.38p each that will see a new strategic partner take a stake in the company.
Egdon Resources PLC (LON:EDR), up 10%. Investors moved into the shares of the UK onshore oil & gas company, egged on ostensibly by the interim results, although as oil analyst Malcolm Graham Wood suggested, the numbers are not that meaningful, and all the sizzle is provided by the imminence of drilling at Holmwood, adjacent to the high-profile Horse Hill discovery.
FALLERS
RPS Group PLC (LON:RPS), down 16%. The environmental consultancy group took a tumble after it said at its AGM that the travails of the oil & gas industry continue to hamper performance.
Carpetright PLC (LON:CPR), down 15%. In the words of David Bowie, the wall-to-wall is calling for shareholders of the floor coverings seller, which disappointed with like-for-like year-on-year sales growth of 0.7% in the 12 weeks to 23 April.
Petra Diamonds PLC (LON:PDL), down 13%. The third quarter trading update from the diamond digger failed to sparkle as it revealed poorer quality production mixes at Cullinan and Koffie had an impact on pricing.
Below are some of the main news-driven share price changes at 9.30am.
RISERS
Strategic Minerals PLC (LON:SML), up 37%. Another day, another massive rise for the Hanns Camp nickel/copper prospect in Australia. The share price has tripled since it lodged its application to start drilling at the prospect last week.
Greatland Gold PLC (LON:GGP), up 15%. Paul Johnson, a non-executive director of Greatland, purchased 2.26mln shares at an average price of 0.24 pence per share, sending the shares shooting up to 0.30p.
Mirada PLC (LON:MIRA), up 11%. The TV set-top box software solutions provider has signed two value added agreements with resellers in India and Latin America.
FALLERS
Snoozebox Holdings PLC (LON:ZZZ), down 59%. Another day, another massive fall for Snoozebox, the portable accommodation company that parted ways yesterday with its CEO. Today it issued details of its business review and a profits warning.
Cobham PLC (LON:COB), up 19%. Talking of profit warnings, the defence group said first quarter trading was behind the board's expectations. It is close to breaking its lending covenants so it has launched an emergency fund-raising.
World Careers Network PLC (LON:WOR), down 19%. Costs are rising faster than revenue at the recruitment software provider and this will hit profits this year.
