Deadline: Tuesday marked the end of 2015’s second quarter and first half. And based on changes in stock prices, Wall Street couldn’t get enough of the Netflix story. The streaming video company’s shares appreciated 57.8% in the quarter and 92.4% since the end of 2014. No one else came close. It was a relatively good time for industry stocks. The Dow Jones U.S. Media Index appreciated 3.3% since the end of March. That beat the Standard and Poor’s 500, which slipped 0.2% and the Dow Jones Industrial Average, which ended the quarter down 2%.
