Seth Fiegerman says, “Twitter’s second month as a public company is off to a promising start.The social network’s stock topped $51 a share in early trading Tuesday, a gain of more than 4% and a new high for the company. Twitter’s stock had previously shot up by more than 9% in trading on Monday, its biggest single-day gain since going public on Nov. 7.
