Shares of Netflix soared, trading 19.6 per cent higher as of 2.24pm in New York, after it reported an increase in the number of subscribers that far exceeded analysts' estimates.

"Netflix showed that the qualitative virtues often cited by bulls-secular growth of internet video, global scale, a commitment to quality content, and singular focus-could drive robust subscriber growth even in the face of well-documented headwinds," Anthony DiClemente, an analyst at Nomura Securities, wrote in a note to clients Tuesday, Bloomberg reported.
