Royal Mail Group's (RMG) stock was dented on Tuesday by comments from Credit Suisse, which said it sees "no near-term positive catalysts" for the postal company.The bank slashed its target price for the shares from 460p to 360p as it kept an 'underperform' recommendation, saying that RMG's margin targets this year "will be difficult to achieve".Earnings downgrades for Meggitt are likely, according to Investec, which put its rating for the stock under review following a worse-than-expected first half from the aerospace engineer."Meggitt's recent performance has been disappointing, and likely to impact the potential for a re-rating. Our rating, target price and forecasts are under review, but we are generally more cautious," the broker said.JPMorgan Cazenove has upgraded its rating for Intertek from 'neutral' to 'overweight', saying that the product testing group has reached an inflexion point for organic growth.The bank said that Intertek's shares are "still quite highly rated" - trading at 17.5 times forward earnings - at a 29% premium to the FTSE 100, though this is the stock's lowest premium to the index since February 2010.The recent weakness in Imagination Technologies' share price has prompted Liberum to hike its recommendation for the stock from 'hold' to 'buy', saying it now sees significant upside if the chip designer can deliver on its targets."Imagination's share price has been weak, declining by 28% since [its annual] results in June. We see an attractive risk-reward at this level," Liberum said.
