Top 2 Retail Growth Stocks to Buy After Amazon's Latest Sell-Off

By Jennifer Saibil – Mar 15, 2026 at 4:25AM ESTKey PointsWalmart and Costco are both reporting high e-commerce growth.Walmart has more than 5,000 U.S. locations that can get deliveries to customers quickly.Costco is demonstrating high renewal rates and membership growth. The market continues to punish Amazon (AMZN 0.87%) stock, with another drop after it released its latest earnings results. Today, the market seems to value Amazon more for its artificial intelligence (AI) development than advances in retail e-commerce, but e-commerce is still its largest business. Although the company has no real competition in the space right now, accounting for nearly 40% of U.S. e-commerce, many other retailers are building thriving e-commerce segments to complement their retail businesses. If you're looking for top choices, I recommend Walmart (WMT +0.99%) and Costco Wholesale (COST +0.50%). Image source: Walmart. 1. Walmart Walmart has fallen to second-largest retailer in the world behind Amazon as of the end of 2025, but the market continues to prize Walmart's consistent growth and emerging digital business. It has the largest store footprint in the U.S., with more than 5,000 stores, and it keeps finding new ways to boost its business.

E-commerce sales increased 24% year over year in the 2026 fiscal fourth quarter (ended Jan. 27), with a 27% increase in U.S. e-commerce. It has its own Prime-like membership program called Walmart+, which has been growing quickly, and membership income increased 15% year over year in the fourth quarter. Members are enjoying the quick delivery, and Walmart has an advantage in fast delivery because of its huge store base. Fast deliveries increased 60% year over year, demonstrating the opportunity here. Walmart is a dependable Dividend King. And it's both resilient and innovative, making it a top long-term play. 2. Costco Costco stock is finally back in the market's good graces after reporting another stellar earnings report for the 2026 fiscal second quarter (ended Feb. 15). Sales were up 9.1% year over year, and comparable sales rose 7.4%. Whatever reservations the market had about Costco's ability to keep growing despite inflation seem to have vanished.

Like Walmart, Costco is leveraging its distinctive edge to boost what it calls digitally enabled sales, which encompasses its robust order pickup business in addition to home deliveries. Digitally enabled sales increased nearly 23% year over year in the quarter. Total app visits were up 63%, while site traffic rose 35%, and average order value increased 15%. That bodes well for the company's future in this space. As usual, membership renewal rates remain high at nearly 90% globally and 92.5% in the U.S. and Canada, and membership growth was up 4.8%. Costco stock is up 16% this year, outpacing the market as it demonstrates resilience and value.Read NextMar 14, 2026 •By Lawrence NgaThe Walmart Metric to Watch in 2026Mar 13, 2026 •By Lawrence NgaWill Walmart's Digital Push Pay Off in 2026?Mar 12, 2026 •By Catie HoganThese Consumer Staples Stocks Will Never Go Out of StyleMar 10, 2026 •By Jack Delaney1 Retail Stock I'd Rather Own Than Best BuyMar 8, 2026 •By James BrumleyHere's Everything Investors Need to Know About Walmart's New CEO, John FurnerMar 7, 2026 •By Lawrence Nga3 Risks That Could Erode Walmart's Long-Term Competitive AdvantageAbout the AuthorJennifer Saibil has been a contributing Motley Fool stock market analyst covering the consumer goods and financial sectors since 2019.
