Meta, whose stock was trading at an over one-year high, is set to add around $80 billion to its market valuation and overtake Nvidia Corp (NVDA.O) as the best-performing company in the S&P 500 index (.SPX) on a year-to-date basis, if gains hold.

The rally also lifted other tech companies from Snap Inc (SNAP.N) and Pinterest Inc (PINS.N) to Amazon.com Inc (AMZN.O) by as much as 3.1%.

"If you want to be treated and valued like a growth stock, you need growth! And this is precisely what Meta delivered returning to growth ... just as questions around a potential recession get louder," Bernstein analyst Mark Shmulik said in a note.

Shmulik was among the 27 analysts who raised their price targets on Meta, pushing the median view to $270, which represents an upside of nearly 13% to a stock that is already leading gains among Big Tech companies this year.

Meta beat expectations for first-quarter profit and revenue, which rose for the first time in nearly a year, the latest sign that American tech giants were digging themselves out of a slump that has sparked tens of thousands of layoffs.

The results also underscored the rising importance of AI, with CEO Mark Zuckerberg saying the tech was helping to boost traffic to Facebook and Instagram and earn more in ad sales.

"We believe AI has played a crucial role in shifting Meta from showing a more limited set of friends, family, and followed content to an almost unlimited set of recommended content now available in Reels and Feed," J.P. Morgan analysts said.

Zuckerberg also said the company, which has carried out several expensive overhauls to bolster its core business, was no longer behind in building out its AI infrastructure.

"Year of efficiency paves the way to AI offense," Roth MKM's Rohit Kulkarni said.

Some investors were, however, sceptical of the share rally.

Eric Schiffer, CEO at private equity firm Patriarch Organization, said the results were better than estimates but they came at a time when expectations have been running low and that valuations have gotten too high considering the economic outlook.

Shares of America's biggest tech companies including Apple Inc (AAPL.O), Microsoft Corp (MSFT.O), Amazon and Alphabet Inc (GOOGL.O) have risen by around a quarter so far this year after a poor 2022.

"Big Tech could be in for a tough second half," Schiffer said, adding that it was a good time for investors to short their shares.
