Google parent Alphabet's stock price fell Wednesday.
  • Alphabet shares slid 6% Wednesday.
  • The losses came after the Google owner posted earnings for the last three months of 2023.
  • Disappointing ad revenue is dragging on Alphabet stock ahead of the opening bell, say analysts.

Shares in Alphabet fell Wednesday as investors reacted to an earnings report that showed advertising revenues falling short of Wall Street's expectations for the Google owner.

The stock was down 6% shortly after the opening bell — a decline that wiped about $110 billion off its market capitalization, per Business Insider's calculations.
