Below are some of the main news-driven share price changes at the close.

Trinity Exploration & Production (LON:TRIN), up 35.0%. Not sure why the shares have gone up on the day Legal & General reduced its stake below 10% to 9.84%, but as Run DMC once said, it's like that, and that's the way it is.
Spectra Systems (LON:SPSY), up 22.4%. The machine-readable high speed banknote authentication and brand protection technologies developer gas acquired certain speciality phosphor assets primarily used in the authentication of world banknotes for US$3.15mln and, more importantly, with them a whole slew of new customers.
FALLERS
Sarossa (LON:SARS), down 8.2%. The shares fell to 1.34p as the investment company revealed it bought back 2mln shares at 1.31p each.
Formation Group (LON:FRM), down 6.0%. A record year for the property development company, but still not good enough for the market, even though it returned to profit.
Harvey Nash Group (LON:HVN), down 5.7%. The shares dipped 4.5p to 74.5p as the company revealed directors acquired 570 shares – yes, 570 – in aggregate at 79p a pop .

Antofagasta (LON:ANTO), down 3.4%. It has not been a good day for miners, and an 'under-perform' recommendation from Credit Suisse has not helped FAGS much.

RISERS
Petroceltic (LON:PCI), up 38.5%. It has been a week since 29.6% stakeholder said it was mulling a bid for the company, and either something is afoot or someone is taking a flyer.

Proxama (LON:PROX), down 11.9%. The digital marketing firm is mulling the sale of its digital payments business after receiving a number of indications of interest. Investors focused more on its underlying loss of £5.3mln, though encouraging it only lost £1.8mln in the second half of the year.
