‘Stay Long’ Amazon: Gene Munster

Amazon.com's announcement of a TV set-top box for streaming content was a nonstarter, but the e-commerce story was still compelling, Piper Jaffray's Gene Munster said Wednesday.

"It's a crowded space. It doesn't make a ton of sense for them to be there," he said in regard to the streaming TV device. "The good news is they have a real business around e-commerce that they can focus on when they're not playing with this other stuff."

Amazon.com reports quarterly earnings Thursday after the closing bell.

On CNBC's "Fast Money," Munster said that it was an attempt by the online retailer to create an ecosystem for its customers.

"They just want to make it easier and easier for you to consume their content," he said. "That's why they came out with the Kindle and the Kindle fire, and ultimately why they may come out with an OS for a phone."

Asked if he would prefer Google or Amazon.com, Munster went with the former.

"Ultimately, Google's going to be getting into other areas that are exciting longer-term," he said.

Munster said that he expected Amazon.com to guide down by 6 percent and saw pressure from "bad press" in Germany, one of their largest markets.

But Munster was still a believer in Amazon.com.

"Longer term you still stay long this, but it's hard to predict how this is going to trade tomorrow," he said.
