Some stocks are best avoided. We really hate to see fellow investors lose their hard-earned money. Anyone who held Petco Health and Wellness Company, Inc. (NASDAQ:WOOF) for five years would be nursing their metaphorical wounds since the share price dropped 90% in that time. Shareholders have had an even rougher run lately, with the share price down 14% in the last 90 days. We really hope anyone holding through that price crash has a diversified portfolio. Even when you lose money, you don't have to lose the lesson.

Since Petco Health and Wellness Company has shed US$62m from its value in the past 7 days, let's see if the longer term decline has been driven by the business' economics.

Given that Petco Health and Wellness Company didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. That's because it's hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

Over five years, Petco Health and Wellness Company grew its revenue at 3.8% per year. That's far from impressive given all the money it is losing. It's not so sure that share price crash of 14% per year is completely deserved, but the market is doubtless disappointed. We'd be pretty cautious about this one, although the sell-off may be too severe. We'd recommend focussing any further research on the likelihood of profitability in the foreseeable future, given the muted revenue growth.

A Different Perspective

Investors in Petco Health and Wellness Company had a tough year, with a total loss of 18%, against a market gain of about 15%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, longer term shareholders are suffering worse, given the loss of 14% doled out over the last five years. We'd need to see some sustained improvements in the key metrics before we could muster much enthusiasm. It's always interesting to track share price performance over the longer term. But to understand Petco Health and Wellness Company better, we need to consider many other factors.
