Shares in natural resources giant ENRC moved higher after Russian billionaire Suleiman Kerimov bought a 2.86 per cent stake in the group. Kerimov's purchase, which is estimated to have cost in the region of $176m, takes his share in the company to 3.05%. HSBC was also on the rise after posting a 95% increase in pre-tax profits in the first quarter as the bank slashed costs and bad debts. Profit before tax for the three months to March 31st came to $8.4bn, up from the previous year's $4.3bn, as revenue rose by 14% to $18.4bn from $16.2bn. BT Group also got a boost after Citgroup raised its target price on the stock from 250p to 300p. Meanwhile, shares in secure outsourcing group G4S dipped after the group published its first quarter results revealing a 0.6% contraction in group operating margin when compared to one year earlier. The group said that this reflected four main reasons, including continued challenging economic and trading conditions in Continental Europe, ongoing pricing pressure in the UK and Ireland, the mix effect of new contracts starting in the UK and the impact of a £6.0m charge in the African region.
