Credit Suisse keeps its outperform rating on spread-betting firm IG Group (IGG), but slightly cuts the target price after factoring in lower growth estimates.The company said it generated £320m of revenue and £163m in pre-tax profit in the year ended 30 May, after accounting for a charge of £2.5m on the closure of the sports business, extrabet.Due to a combination of lower revenue growth estimates (7%), the exclusion of extrabet and broadly constant earnings margins, the Swiss broker cuts its pre-tax profit forecasts for the year ending May 2012 by 4.8% to £175.2m. Earnings per share estimates are cut by 4.1% to 35.1p.As such, the target price falls to 530p, from 550p.Good trading momentum and strategic progress at Playtech has led Peel Hunt to raise its rating on the online gaming software developer from hold to buy."Playtech remains a unique opportunity in the online gaming sector and, whilst there are some challenges, its business model continues to look sound in a more heavily regulated industry.
