Alphabet Inc. rose more than 4% in premarket trading after the parent of Google smashed Wall Street's third-quarter earnings expectations. Alphabet reported third-quarter net income of $6.73 billion, or $9.57 a share, coasting past analyst estimates of $8.31. Revenue surged 23% year over year to $27.7 billion, higher than the $27.2 billion analysts were expecting.

Traffic acquisition costs, or what Google pays to get ads in front of mobile users, spiked 54% during the quarter but Wall Street didn't seem too concerned since Google's overall ad business continues to grow.
