Senior Research Analyst Gene Munster made a bullish case for Amazon.com on Tuesday saying he believes the e-commerce company's stock is the best positioned over the next five years.
The firm Piper Jaffray released a note to investors Tuesday that said Amazon's unit growth stability, increased in part by its Prime membership program and faster delivery speeds, should continue. It also expects growth from Amazon's future expansions in new categories.
"It's going to be difficult for traditional retailers to re-gear how they've been distributing their products ... Let alone to tap into what we believe [is] 65 million Prime users," Piper Jaffray analyst Muster said on CNBC's "Fast Money Halftime Report," who gave the company an "overweight" rating and a maintained price target of $900.
Muster added it'll be hard for retailers to compete with Amazon's same-day delivery service, which he says is offered in 40 cities with additions coming soon.
"Generally, Amazon is not considered the first company or the best company of that breed, but, in fact, we think it is," he said.
The bullish analyst said risks to Amazon's growth include slowed consumer spending and e-commerce competition.
Some traditional retailers have been gearing up for competition in online shopping. In August, retail giant Walmart agreed to purchase Jet.com for $3.3 billion in attempt to dethrone Amazon. Jet wouldn't only give Walmart a shot at catching up to Amazon, but it may also help the company tune its shipping and online logistics.
Amazon's stock was trading slightly lower early afternoon Tuesday at $835.29. The stock is up more than 23 percent year to date.
