Evraz rose into the top spot as the prospects of greater demand from Asia looked up, boosted by the release of a sharp upwards revision to Japanese growth estimates for the last three months of 2012. Shares in financial companies were also making decent gains in early trading as risk appetite increased after the closely-watched US job report smashed forecasts on Friday. Insurance giant Aviva was rebounding, albeit only slightly, after plummeting on Thursday. Shares sunk yesterday as the company slashed its dividend for 2012 after swinging into the red as it took a £3.3bn write-down on a disposal in the US. Meanwhile, Kazakhmys declined after Nomura reduced its target price from 700p to 475p and retained a reduce rating. Temporary power and temperature control group Aggreko retreated after making strong gains following an impressive set of 2012 results. Shares in British Gas owner Centrica were under pressure on Friday after JPMorgan Cazenove downgraded its rating on the stock from 'overweight' to 'neutral'. While the broker still sees Centrica as its top pick in the UK utilities sector, it has lowered its recommendation given the shares' re-rating over the last year. It has also removed the stock from its 'Analyst Focus List'.
