There is also a strong pipeline in place for the purchase of larger portfolios of paying/performing loans. However, that means the timing of investment flows remained "unpredictable" given its intention to carry out further such acquisitions.Chief executive Nigel Terrington said: "The group is well placed to generate further growth in each of its target markets and continues to focus on improving shareholder returns through active capital management."Very mixed verdict from analystsShore Capital analysts have a 'buy' recommendation on the stock and a 412p target price as the "upbeat" results showed "continued strong momentum in key business metrics".However, broker Numis has the shares at a 'sell' with a target price of 268p, as they believe the mark-to-market net asset value is "substantially lower than that disclosed"."The return on equity remains about the worst in the sector with unsustainable below the margins flow margins, almost no impairment and exceptional returns from Idem," the broker continued.Shares were up 1.36% to 417.8p on Thursday at 10:17.
