Below are some of the main news-driven share price changes at 4.00pm.
RISERS
Gulf Keystone Petroleum (LON:GKP), up 27.2%. New payment terms announced by the Kurdish Regional Government included an element for paying off some of the arrears that have accumulated.
Nighthawk (LON:HAWK), up 18.0%. Management's expectations are that total revenues for the year ended 31 December will be significantly higher than current market expectations.
Plutus PowerGen (LON:PPG), up 18.0%. The shares rose to 1.15p after executive director Charles Tatnall and chief financial officer James Longley both exercised warrants to buy 10mln shares each at 0.9p a pop, netting £180,000 for the company.
FALLERS
Mosman Oil and Gas (LON:MSMN), down 52.6%. Mosman's chairman, John Barr, told Proactive Investors, he was “shell-shocked” after pulling out of the proposed acquisition of the South Taranaki Energy Project (STEP) after months of due diligence. Barr blamed the decision on the collapse of oil prices.
Strategic Minerals (LON:SML), down 37.3%. The company has moved away from bulk metals like iron and coal, securing an option to acquire up to 50% of an Australian firm with nickel and rare earth exploration potential.

Below are some of the main news-driven share price changes among FTSE 350 stocks at 12.30pm.
RISERS
Home Retail Group (LON:HOME), up 5.7% to 144.2p. Reports last week suggested talks with J. Sainsbury (LON:SBRY) over a takeover had stalled. Reports in The Times suggest the supermarket chain has been told by the Argos owner's major shareholder that any bid would need to be around the 160p a share mark.
Allied Minds (LON:ALM), up 4.7%. The company's Federated Wireless subsidiary has raised US$22mln at a price that suggests the value of the company has risen from US$10mln to US$82mln. Allied Minds owns 73% of Federated Wireless. The share price rise lifts Allied Minds' market value to £640mln.
BT Group (LON:BT.A), up 3.1%. The telecoms giant's third quarter top line showed more signs of life than the market had been expecting. Deutsche Bank still says sell.
LOSERS
Vedanta (LON:VED), down 6.0%. Deutsche Bank has cut the price target from 200p to 185p.
BP (LON:BP.), down 3.2%. Ahead of tomorrow's results, Deutsche Bank has shaved 5p from its 450p target price, though it is likely that the fall in the oil price today is having a much larger impact on the share price.
Antofagasta (LON:ANTO), down 2.9%. AlphaValue has cooled a little on the copper miner, moving to “add” from “buy”.
Below are some of the main news-driven share price changes at 9.15am.
RISERS
Premier Oil (LON:PMO), up 96.1%. Trading in the company's shares has resumed after the announcement last month of the proposed acquisition of E.ON's North Sea Assets. After a bit of jiggery-pokery, the acquisition is now categorised as a “Class 1” transaction rather than a reverse takeover.
North River Resources (LON:NRRP), up 38.5%. The company has received a “notice of preparedness” from Namibia's Ministry of Mines and Energy to grant the mining licence for the Namib lead-zinc project.
7Digital (LON:7DIG), up 19.8%. The shares rose to 15.75p on news that non-executive director Paul McGowan has bought 250,000 shares at 13.25p each.
FALLERS
Auhua Clean Energy (LON:ACE), down 56.1%. The company's nominated adviser has served notice to quit. The company is in talks to appoint a replacement.
Lakehouse (LON:LAKE), down 53.6%. A trading update revealed its clients are deferring spending decisions because of budget constraints, prompting a profit warning from the building maintenance services provider.
Litebulb (LON:LBB), down 48.2%. The branded product developer advised shareholders that its quest to refinance its convertible loan notes will probably result in some of the debt being converted into equity. Seeing as there are £6.6mln of loan notes outstanding and the company's market capitalisation was around £2mln before this morning's share price plunge, that implies a lot of dilution for existing shareholders.
