Goldman Sachs Group Inc. beat back more than $300 million in claims from two co-founders of Marvell Technology Group Ltd. who alleged the investment bank tricked them into selling shares of their company. A Financial Industry Regulatory Authority arbitration panel denied claims from Marvell Chief Executive Officer Sehat Sutardja and President Weili Dai. The pair had requested the return of 8.65 million shares of the Hamilton, Bermuda-based mobile-phone chipmaker, plus as much as $200 million in damages, according to a Finra filing.
