Shares of Netflix Inc. are on a tear, and nobody is more surprised than Chief Executive Reed Hastings.

The stock NFLX, +3.70% has more than doubled this year and enjoyed another roughly 15% boost Thursday after the company reported better-than-expected second-quarter earnings.

“I think it probably shows why at least I should keep my day job and not try to be a stock picker,” Hastings said on the company’s earnings call. “When the stock was half this price I described it as euphoric. So it’s a mystery to me. I think I’m out of the stock commentary business.”

Analysts weighing in on the report were upbeat, and many think the stock should be even higher.

Netflix reported second-quarter per-share earnings of 6 cents, topping Wall Street estimates of 4 cents. Revenue of $1.64 billion was pretty much in line with the FactSet consensus of $1.65 billion. But the real linchpin for analysts was the strong growth in international subscribers.

Netflix said it added 3.3 million new subscribers in the quarter—0.9 million domestically and 2.4 million internationally. The new members helped Netflix eclipse 65 million members worldwide—42 million in the U.S. and 23 million internationally.

“Netflix posted a meaningful subscriber beat despite a high guidance hurdle, adding nearly double the number of subscribers as its next closest second quarter in any prior year,” Stifel Nicolaus analyst Scott Devitt wrote, raising his price target to $128 from $104.

“Netflix’s subscriber growth is seemingly firing on all cylinders as the company benefits from a strong content slate, including an increasing proportion of original/exclusive content and growing global brand recognition.”

The average FactSet target price is $109.23, which is now below the stock’s current level, making it likely that more price target hikes will emerge. Hastings said on the call that he expects domestic subscriber growth to maintain a 5 million to 6 million growth rate in each quarter.

“We believe Netflix is on track toward significantly disrupting the linear TV market through strong subscriber growth, and a better consumer proposition,” said J.P. Morgan Chase analyst Doug Anmuth.

Anmuth raised his price target 42% to $127 from $89. “Higher subscribers have a disproportionately larger impact on profitability as relatively fixed content costs account for the majority of Netflix’s costs,” he wrote.

Hastings told investors after the first quarter that he expected losses in international markets to grow to about $101 million in the second half as the company moved forward with its expansion. Netflix reported losses of $92 million for the second quarter, and said it expected losses of $77 million for the third quarter. Chief Financial Officer David Wells said managing the losses has been all about the timing of Netflix’s launches.

“We kind of tried to walk through that in terms of the timing,” Wells said on the call. “We’ve got a Japanese launch later this quarter. And then in Q4 you’ll see Southern Europe, Spain and Italy. So you should expect those losses to continue to kind of work toward that. And then next year we’ve got the rest of the world.”

Hastings said 2015 would not be the peak of international losses—that should come next year.

Of the 25 analysts tracked by FactSet, 13 have a price target above the company’s currently trading levels. Pivotal Research Group analyst Jeffrey Wlodarczak has the highest target at $155, or 35% above current levels.

On the low end, Wedbush analyst Michael Pachter has a $40 price target. The stock’s high valuation is unwarranted due to the potential for slowing domestic subscriber growth, coupled with decreasing international profitability, he said.
