Bloomberg: Netflix has declared a 7-for-1 stock split, rewarding shareholders after its stock doubled this year to lead the Standard & Poor’s 500 Index. The split takes effect on July 14. The company’s market cap has soared eightfold to more than $40 billion since 2012 as Netflix expanded its pioneering web-based TV service to more than 50 countries and signed up more than 62 million subscribers worldwide.
