Rosenblatt analyst Mark Zgutowicz is a buyer of Facebook shares into the company's Q3 results on Wednesday, October 30. Demand side indications remain strong for both News Feed and Instagram as respective return on ad spend remains at the top end of advertiser buys, Zgutowicz tells investors in a research note. However, with Facebook "under a regulator microscope," the analyst does not expect a "big" beat and raise quarter, but rather a modest beat and reduction to 2019 expense growth guidance. With the stock trading at 19 times estimated 2020 earnings, a modest beat will satisfy "the bar," contends Zgutowicz. He reiterates a Buy rating on Facebook with a $242 price target.
