LinkedIn (LNKD) also accelerated its growth again in the quarter, which caused the stock to jump 8% to $230 Friday, with several analysts taking their price targets up to $250.
MercadoLibre (MELI) is up 10% to all-time highs after its profit grew 18% and gross merchandise value grew much faster than expected.
Trulia (TRLA) hit all-time highs Thursday for beating on the top and bottom line for the real estate listings company.
Zillow (Z), Trulia's bigger rival, also hit new highs in sympathy. Its earnings don't come out until next week, but investors are also expecting big things. The stock has risen 45% in the last month.What do all these stocks have in common? They all rely on mobile for their growth. More important, they've all figured out how to make money from mobile through either ads, placements fees, transaction fees, listings fees, or through selling profiles of their members to interested parties. Has it changed the world of mobile stocks forever? It sure seems so. The biggest inflection point to come for mobile stocks may be when we finally see mobile cost per clicks (CPCs) actually pass desktop CPCs. That's something that would have seemed like crazy talk a year (or even 6 months) ago, but it is possible to think of that today. Why? Well, if there's one message to take from all these companies, it is this: Money will follow where the users are, and users are moving en masse to mobile. That's a phrase that Marissa Mayer at Yahoo! (YHOO) has been saying for months. It hasn't really translated into any meaningful revenue for the company yet, but the logic is sound and all these mobile companies are showing that it's true. As the world moves to mobile, the same advertisers, job hirers and others who had to reach people on desktop have to do the same in mobile. The economics of reaching those people will move in fits and starts but it will eventually transition almost completely over from desktop to mobile. The former kings of the Web may or may not make the crossing of the chasm to mobile. But one thing's for sure after these last 10 days: The upstarts are figuring out how to make money in this brave new mobile world, and Wall Street is rewarding them, big time.
