Many retailers have experienced a boon to their businesses thanks to a strong U.S. economy. But some companies are faring better than others and are positioning themselves for more growth in the coming years.

To help investors narrow down their search for some of the best retail stocks to buy right now, we asked three Motley Fool contributors for their top picks. They came back with Amazon.com(NASDAQ:AMZN), Walmart (NYSE:WMT), and Target Corporation (NYSE:TGT). Read on to find out why.

Because of its higher-margin profile, AWS allows Amazon to grow its bottom line and essentially subsidizes its lower-margin e-commerce business. Although Microsoft has recently emerged as a formidable challenger in the cloud, look for AWS to continue to grow at a rapid clip, as Gartner expects the overall industry to grow 58% over the next two years.

However, in-the-know investors are starting to get more excited about Amazon’s digital marketing opportunity. Although its in the nascent phases, Amazon is taking on Alphabet‘s Google and Facebook by posting 130% year-over-year growth rates in its “other” division, which primarily consists of digital marketing revenue. As of last quarter, Amazon reported a run rate of nearly $10 billion in this presumably higher-margin business. Look for the combination of these three businesses to boost Amazon’s stock price for years to come.
