Amazon.com  (AMZN - Get Report) shares were rising slightly in premarket trading Monday after analysts at KeyBanc and Deutsche Bank raised their price targets on the company. 

KeyBanc now has a $2,200 price target on Amazon, up from its previous view of $2,100, while Deutsche Bank has a $2,515 price target, up from $2,315. Amazon shares were trading at $1,972.95, up 0.4%.. 

KeyBanc's more bullish outlook is thanks to its positive view of the U.S. retail sector and the fact that Amazon executed its annual Prime Day sale without any major disruptions.

"As expected, Prime Day was again the largest sales day in Amazon history, and was bigger than both Black Friday and Cyber Monday combined. While Prime Day falls in the F3Q, we expect to hear additional details regarding the performance, particularly around the sales of Amazon devices," wrote analyst Edward Yruma.

Meanwhile, Deutsche Bank analyst Lloyd Walmsley is bullish on the company's revenue and unit growth in the third quarter, which should offset some of the cost of the company's decision to move to one-day prime shipping. 

"For starters, it is a natural extension of the guaranteed two-day delivery Amazon offers to Prime members on most SKUs, and Amazon has been offering one-day
delivery on select items in select markets for a couple of years now. Second, it raises the competitive bar for other retailers, who cannot match on speed / cost even in the mid-to-long term, given lack of scale. Third, it reduces Amazon's dependence on the USPS for the last mile," Walmsley wrote.
