Chewy (CHWY 0.19%), the online pet retailer, is set to report first-quarter earnings on June 10. The company is experiencing surging sales during the pandemic with many folks looking to avoid shopping in stores. 

Sometimes referred to as the Amazon of pet stores, because it sells exclusively online, Chewy also caught a tailwind from increased pet ownership during the pandemic. Many found that furry friends help make passing time at home a bit more pleasant. And unsurprisingly, many of those same folks looked to Chewy.com to deliver things necessary to keep their newfound companions happy and healthy. 

As of this writing, the stock is up over 77% in the last 12 months as investors anticipate some of the customers gained during the pandemic will stick around long term. But has the stock run up too far, too fast? Or should investors still buy it ahead of the company's June 10 earnings announcement?

Near-term expectations 

Chewy is guiding for revenue of $2.12 billion at the midpoint, which would be year-over-year growth of roughly 30%. That would be a deceleration from the previous quarter's rate of 50.8%. Note, however, that management gave this guidance several months ago, before consumers got stimulus checks of $1,400 per person in March and April.

Those stimulus checks have fueled better-than-expected sales at several retailers, from Home Depot to Macy's. This phenomenon could cause Chewy to exceed its revenue guidance in the first quarter.  

Chewy is forecasting revenue of $8.9 billion at the midpoint for the fiscal year, which would be year-over-year growth of roughly 24%. However, keep in mind that this is following a tough comparison in 2020, where revenue surged by 47.4% due to the pandemic.

Is Chewy stock a buy? 

The company benefited from a surge in sales during the pandemic, but that doesn't mean it will lose those sales in the aftermath. Instead, Chewy is riding a longer-running tailwind from people moving spending away from brick-and-mortar stores to e-commerce.

Moreover, pets are a long-term commitment for most people; those bought or adopted are growing older and larger during the pandemic. According to industry analysts, pet ownership grew by 5.7% in 2020, almost 10 times faster than the 0.6% compound annual growth rate before the pandemic.

That's in part what's causing forecasts for the pet industry to grow from a $100 billion market in 2020 to $120 billion in 2024. Chewy has roughly 7% market share right now, and as more sales move online, that share is likely to increase.

The stock trades at a forward price-to-sales ratio of 3.4. Interestingly, the forward P/S multiple was correlated with its quarterly operating profit margin — it increased as its operating profit margin increased. Recently, however, the two have diverged (see chart): Its P/S has declined as operating profit margin continued to increase, and that could be a buying opportunity for investors

Its excellent long-run prospects and recent price decline mean that those interested in starting a position in Chewy can feel pretty good about buying shares ahead of earnings. But if you want to take a more cautious approach, you could split your purchase allocation in two and buy half ahead of earnings and half in the days following the announcement.
