The third quarter has been strong for retailers from Walmart WMT to Macy’s M. With that said, grocery power Kroger KR is one of the last massive retailers to report its Q3 earnings results later this week. So, let’s see what to expect from Kroger to understand if KR stock might be worth buying. Overview At this point, roughly 90% of the S&P 500’s retail sector has reported their quarterly earnings results, with total earnings for these retailers up 27.1% from the year-ago quarter on 6.8% higher revenues. But what does this mean for Kroger as it fights against Target TGT, Walmart, Costco COST, and others in the age of Amazon AMZN?Kroger currently offers online ordering and curbside pickup through its ClickList service. The Cincinnati-based company has also expanded its partnership with grocery delivery startup Instacart, which works with the likes of CVS CVS, as part of its Restock push. The company is also ready to roll out meal kit offerings after it purchased private meal kit firm Home Chef in an effort to compete against the likes of Blue Apron APRN.Plus, Kroger is currently working with Nuro to pilot autonomous grocery delivery. On top of that, Kroger partnered Chinese e-commerce behemoth Alibaba BABA to sell some of its brands in China.

Yet, we should note that despite KR’s solid 10% climb over the last 52 weeks, Kroger stock sits below its 52-week high and far behind its all-time high. Kroger stock closed regular trading Monday at $29.75 per share. This marked a roughly 9% downturn from its 12-month high, and sets up what could prove to be a solid buying opportunity for investors high on Kroger stock.

Looking ahead, the company’s third-quarter revenues are projected to dip by 0.61% to reach $27.58 billion, based on our current Zacks Consensus Estimate.

Bottom Line Kroger is currently a Zacks Rank #3 (Hold) and sports an “A” grade for Value and a “B” for Momentum in our Style Scores system. The company has also started to roll out its plans for the future.
