- Loup Ventures founding partner Gene Munster tells CNBC that Netflix's stock is a tough one to have in your portfolio.
- The company beat on earnings but slightly missed analysts’ expectations for revenue.
- "This was positive to expectations, but this is still a story that I think would be difficult to own," Munster says.

While Netflix reported an earnings beat, the video-streaming giant missed expectations on domestic paid subscriber additions and fell slightly below analysts' revenue expectations. It did exceed expectations for international paid subscriber additions.
Munster, who argued in July that Netflix's best days "are in fact behind it," continued to evince a bearish outlook Wednesday.
"Ultimately, for this to work, they need to have margin expansion and continue to grow [subscribers]. We're entering a multi quarter of really uncertainty," Munster said.
The issue, Munster said, is he does not see a clear path for Netflix to expand its margins. He said he was "surprised" to see Netflix say it expected 300 basis points of margin expansion next year.
"I don't know how you get there," Munster said. "The easiest way to get there, obviously, is through price increases, which is now off the table ... and you continue to need to fund this quite aggressively. The one opportunity is if they can get cheap debt."
Netflix currently has $12 billion in debt, Munster said.
"There may be an opportunity to have some sort of trade-off there, where they can get margins to inch higher," he said. "But I think that is at the core question: How do you operate expanding margins in what is a very different competitive environment than we had a year ago?"
The increased competition is coming from new streaming services debuting in the next 12 months, including Disney's Disney+ and Apple's Apple TV+, in addition to NBCUniversal's Peacock and WarnerMedia's HBO Max.
Overall, Munster said, he grades Netflix's third quarter at a C+.
"The stock reaction would suggest a higher grade, but ultimately, this trend is there is some cautionary tales here," he said.
