Internet exchange traded funds popped Tuesday on better-than-expected third quarter results from Netflix (NasdaqGS: NFLX) that surpassed speculation of a slowdown in net subscriber growth.

NFLX surged 19.4% Tuesday as international subscriber growth outpaced guidance and the company revealed a strong outlook, reports Anita Balakrishnan for CNBC.

The internet streaming provider posted third-quarter earnings per share of 12 cents, compared to 7 cents per share for the same period last year, on revenue of $2.29 billion, capitalizing on original series like “Stranger Things” and Narcos.” Analysts expected third quarter earnings of 6 cents per share on revenue of $2.28 billion.

“We are now in the fourth year of our original content strategy and are pleased with our progress,” the company said in a letter to shareholders. “In 2017, we intend to release over 1,000 hours of premium original programming, up from over 600 hours this year.”

Netflix also announced a gain of 370,000 net memberships in the U.S. and 3.2 million internationally, beating its initial forecast of 2.3 million new users.

The unexpected strength in Netflix helped bolster internet-related ETFs. For instance, the PowerShares NASDAQ Internet Portfolio (NasdaqGS: PNQI) rose 2.2% and First Trust Dow Jones Internet Index Fund (NYSEArca: FDN) rose 2.1% on Tuesday.
