Alphabet's valuation continues to look attractive as margins stabilize and mobile commerce drives ad growth, and investors should buy the stock ahead of the company's earnings on Feb. 3, KeyBanc said in a note to clients Friday.

The firm raised its target on the stock to a street high of $1,769, which is 19% above where it currently trades.
