The broker has upgraded the stock from "hold" to "buy" while leaving its earnings forecasts unchanged. "The company has made good progress selling down post the rights issue with over £500m of sales since 31 March (this is roughly half what we expect the company to sell post the rights issue)," KBC stated.The broker has a price target of 490p for the stock.
