Phillip Securities upgraded Microsoft (MSFT) and Apple (AAPL) after both companies reported earnings last week. Diane King Hall explains why the analyst sees more promise in the Mag 7 giants. Elsewhere in Big Tech, Palantir (PLTR) has a new bull in William Blair with the firm seeing strong earnings growth ahead.
