Tech Five: Microsoft, Alphabet shares tumble

Lots of activity among tech stocks Friday, as several companies' shares are on the move. Revenue and earnings were down for the tech giant during the third quarter, as it continues its push toward mobile and cloud computing. Microsoft reported earnings of 47 cents a share, down 25% year-over-year. All those investments in self-driving cars and broadband Internet are costing the tech giant. Operating losses from the division behind Alphabet's "moonshots" widened to more than 800 million.
