Investors should buy Netflix shares as the streaming company's international subscriber base will more than triple in four years, according to Goldman Sachs, which reiterated its buy rating.

Goldman analyst Heath Terry estimated Netflix can grow to 125 million international subscribers by 2020 from the 34.5 million at the end of the first quarter.

"Internationally, we believe Netflix is still in the early stages of a long growth cycle. ... The international opportunity could be significantly larger than the domestic one over time," Terry wrote in a note to clients Thursday.
