Rosenblatt downgraded Alphabet (GOOGL) to Neutral from Buy with an $181 price target. The analyst sees “multiple areas of transitional risk” for Alphabet and recommends “stepping back for a little while to see how the company handles it.” Areas of risk include the artificial intelligence’s impact on search, including the likely at least transitionally negative impact on search ad revenues of layering in AI Overviews, the analyst tells investors in a research note. The firm says there is also nascent evidence of Google search share loss to Microsoft’s (MSFT) Bing. And the transitioning of search ad revenue to retail media networks seems set to accelerate as other retailers such as Walmart follow Amazon’s lead and push into this arena, adds Rosenblatt.
