International Personal Finance shot to the top of the FTSE 250 leader board after JP Morgan Cazenove upgraded the stock from 'underweight' to 'neutral'. The broker's target price remained unchanged at 330p. It was beers all round for Mitchells & Butlers in the pub group's trading update, but it wasn't enough to impress shareholders as the share price took a tumble. Peel Hunt has raised its target price on Mitchells & Butlers to 270p from 208p, half-way between what it regards as a "fair value" price and the 230p offer from the Harvester and O' Neill's chain owner's major shareholder, Joe Lewis. The pub group reported a 2.7% rise in like-for-like sales in the first 51 weeks of the year and stood firm on its rejection of the recent offer from its largest shareholder, billionaire Joe Lewis.Rumours of a possible approach from ArcelorMittal continue to surround Morgan Crucible, sending its share price up by 22p.
