Netflix (NASDAQ:NFLX) will report quarterly earnings results on Wednesday, Jan. 22. Having finished 2014 as the best-performing stock in the S&P 500, the streaming video pioneer has a high bar to meet in order to keep its shares improving this year.

In the video below, Fool contributor Demitrios Kalogeropoulos lists three things for investors to watch for in Netflix's fourth-quarter report. First, subscriber growth will be critical, and should come in at more than 2 million new users. Second, look for the company's streaming margin, an indication of the overall profitability of the business, to stay comfortably above 20%. And finally, watch for an update on Netflix's international expansion plans, which slowed in 2013 but could ramp up to target at least one major new market in the year ahead.
