Netflix, Inc. (NASDAQ:NFLX) original program has given the company a boost in its subscription, which increased by 50% in the third quarter. This was more than expected and has resulted in rising of price targets on the stock by various brokerages the likes of RBC Capital Markets and Goldman Sachs Group Inc (NYSE:GS). The premarket trading of Netflix’s shares was up 18% at $117.93.

The sudden boom has been attributed to its latest raft of original series and particularly the supernatural thriller Stranger Things that premiered in July. It can also be linked to the September second season of the Golden Globe-nominated drama Narcos. The creative control in Stranger Things has provided the company with greater business opportunities.

In a research note, J.P. Morgan Securities analyst Doug Anmuth said, “The benefits of NFLX-produced original content including attractive economics and greater control are clear, and we believe returns on original spend are high.”

Netflix original program: The Company is eyeing much more

Caution of the company’s ability to sustain growth

Wedbush Securities analyst Michael Pachter has questioned Netflix’s extravagant expenditure on original and exclusive content. He says that as all this happens, international profitability remains elusive even as competition for both content and subscribers continue to become ferocious. Cash burn is unacceptably high, which creates concerns of how the company will effectively assemble a content library that will validate its high level of spending.

Nonetheless, everyone is keen on how Netflix original program tactic turns out in the next few years. The company’s trading session closed at $118.79, a rise of $18.99 or 19.3%
