Broker tips: Intertek, Unilever, Greggs

RBC Capital Markets has upgraded its rating for Intertek from 'underperform' to 'sector perform', providing a boost to the quality control and testing group's stock on Tuesday morning."We like the testing structural growth story, comps are now more benign and we see a pick-up in M&A as likely. Whilst valuation is still full, we now see limited downside risk."JPMorgan Cazenove has downgraded its rating for consumer products giant Unilever from 'overweight' to 'neutral', saying that earnings downside still persists."Despite the slide in earnings year to date we see further earnings risks at Unilever, as the market has yet to factor in a slower top line growth and muted margin rise as management reinvests to grow. Top line should not only bear the brunt of cyclically lower inflation, but Unilever's market share gain success story is loosing steam while competition is heating up."The share price of Greggs fell heavily on Tuesday morning after the bakery chain reported lower-than-forecast results, something which now raises the execution risk at the company, according to Canaccord Genuity.The broker maintained its 'sell' rating for the stock and cut its target price from 380p to 330p, saying: "There is a significant amount of work to be done and execution risk is high."BC
