Netflix has issued a fourth-quarter forecast that fell short of expectations. The weak outlook suggests the streaming company is having trouble accelerating growth. The announcement puts pressure on management to find a way to speed it up again. The report does not provide the exact financial figures in the forecast. It also leaves out prior analyst expectations and Netflix's explanation for the weak result. There is no information on the stock's reaction after the announcement. Netflix says it wants to kick-start growth, but the report identifies no specific measures or timetable. That leaves investors without clarity on what changes the company plans or when it expects growth to improve.
