Google's parent company Alphabet reported blockbuster fourth quarter earnings, boosted by better-than-expected Google ad revenue and Google Cloud revenue. The results sent Alphabet's stock soaring, and the company could come close to hitting a $2 trillion market valuation similar to other tech giants Apple and Microsoft. The company also announced a 20-for-1 stock split, which would make shares more accessible to would-be investors. Mark Lehmann, CEO at JMP Securities, a Citizens Company, joins Closing Bell to discuss Alphabet's earnings report, whether the company will reach a $2 trillion market cap, its stock split, and more.
