Alphabet shares are up 56% in 2023, but the stock still looks promising, according to Karen Firestone, CEO of Aureus Asset Management. "We still think it's very attractive," she said on CNBC's " Halftime Report ." "I think the amount of intelligence they have put into the search engine is phenomenal and that's just going to continue building," she added. Fellow "Halftime Report" traders Josh Brown, Sarat Sethi and Jim Lebenthal agreed that the stock still has strong prospects, even at this valuation. "This is the one tech stock that I'm overweight … It's attractively priced for a rapidly growing company," said Lebenthal, chief equity strategist at Cerity Partners.
