Today's Market Winners and Losers

The stock market is down Friday, with the Dow Jones Industrial Average down 0.77%, the Nasdaq down 0.72% and the S&P 500 down 0.69%. Today's big winner was a smartphone maker who beat Wall St. earnings expectations and today's big loser was a telecommunications equipment manufacturer that lowered its earnings guidance for the upcoming quarter.

This is Friday's market winner and loser.
