Online Desk : Google-parent Alphabet Inc inched closer to joining peers Apple and Microsoft in the elite $2 trillion market valuation club as the search giant`s shares surged 10 percent on Thursday after another blowout quarter.

The gains, if they hold, could be the biggest single-day gain for the stock since 2015, easing some of the concerns around Big Tech valuation that triggered a sector-wide selloff in the past few days.

"The technology sector started 2022 with some of the biggest question marks over it since the dotcom crash more than two decades ago," said Russ Mould, investment director at AJ Bell.

"However, the largest and highest quality US tech names continue to deliver the answers the market wants with big earnings beats."

The stock rose as much as 10.8 percent to $3,049.5 in trading before the opening bell. At least 20 brokerages raised their price targets on the stock, lifting the overall Wall Street median target to $3,450.

Alphabet also announced a 20-to-1 stock split, which will give shareholders 19 shares for every share they hold, bringing its price down to about $138 based on Tuesday`s close.

Splitting stocks is a method companies use to woo investors by making them more affordable. However, some brokerages, such as Robinhood Markets, allow investors to buy fractions of shares, making the tactic less effective.

Tesla and Apple have also split stocks in recent months to make their shares more appealing to mom-and-pop investors.

"The split will make the shares more accessible for retail investors and likely facilitate inclusion in the Dow Jones Industrial Average (which is somehow still share price-weighted), but it has no fundamental impact," JP Morgan analyst Doug Anmuth said.

Facebook-parent Meta Platforms, which is set to report results on Wednesday, and Amazon.com Inc also rose about 3 percent in premarket trading.

Adding to the rebound in tech stocks, Advanced Micro Devices Inc`s shares jumped 12 percent after its results topped Wall Street expectations. Shares of rivals Nvidia, Qualcomm , Xilinx and Micron also rose.
