Alphabet

Google still dominates the online search landscape, which means Alphabet maintains the inside track on advertising’s continued digital shift. That position has been aided by the company’s investment in artificial intelligence and machine-learning technology that helps generate better returns for advertisers. Alphabet, in turn, deploys that advertising revenue for long-term enterprises like Waymo, its autonomous-vehicle subsidiary. Yet it remains under an intense regulatory spotlight regarding potential antitrust issues—and is sensitive to trade-related factors.
