Netflix was the clear winner and Twitter an equally clear loser in what was generally a pretty good earnings season for media companies based on the market reactions to execs’ quarterly reports and commentaries. Among 25 of the biggest or most interesting companies that I track, 17 beat the overall market in the trading day after they announced their results while eight lagged. I calculated the results by looking at how much each stock rose or fell in the trading day after the company reported. Then, to reduce the effects of changes in the market, I subtracted any gains or added back any declines in the day’s movement of the benchmark Standard & Poors’ 500. The results show that Netflix was +17.4% after it exceeded analyst expectations for its revenues, profits, and domestic streaming subs in the last three months of 2013. But Twitter’s -25.4% indicates that its first earnings report was a bust as CEO Richard Costolo, faced with disappointing sub growth numbers, vowed to make the service easier for newbies to use.
