Facebook’s stock jumped, a sign that the social media company’s complicated relationship with Wall Street may be getting brighter. Besides posting quarterly results that inched past estimates, Facebook on Tuesday also gave details for the first time on how much money it made from mobile ads. Facebook now calls itself a ‘‘mobile-first’’ company, but it only started showing mobile ads earlier this year. Facebook said that nearly $153 million of its $1.26 billion revenue came from mobile advertisements. One Citi analyst said that for the first time since Facebook’s offering, investors see a reasonably priced stock combined with accelerating growth at the company. The analyst noted that ad revenue grew at a faster pace at Facebook at a time when rival Google saw a slowdown.
