Fastly (NYSE:FSLY) shareholders are up 32% this past week, but still in the red over the last five years

Fastly, Inc. (NYSE:FSLY) shareholders will doubtless be very grateful to see the share price up 52% in the last month. But that doesn't change the fact that the returns over the last half decade have been stomach churning. Five years have seen the share price descend precipitously, down a full 79%. It's true that the recent bounce could signal the company is turning over a new leaf, but we are not so sure. The important question is if the business itself justifies a higher share price in the long term.

While the stock has risen 32% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

Our free stock report includes 3 warning signs investors should be aware of before investing in Fastly. Read for free now.

Fastly isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. Some companies are willing to postpone profitability to grow revenue faster, but in that case one would hope for good top-line growth to make up for the lack of earnings.

Over five years, Fastly grew its revenue at 17% per year. That's well above most other pre-profit companies. So on the face of it we're really surprised to see the share price has averaged a fall of 12% each year, in the same time period. You'd have to assume the market is worried that profits won't come soon enough. While there might be an opportunity here, you'd want to take a close look at the balance sheet strength.

A Different Perspective

Fastly shareholders are down 11% for the year, but the market itself is up 9.8%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. However, the loss over the last year isn't as bad as the 12% per annum loss investors have suffered over the last half decade. We'd need to see some sustained improvements in the key metrics before we could muster much enthusiasm. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too. Consider for instance, the ever-present spectre of investment risk. We've identified 3 warning signs with Fastly , and understanding them should be part of your investment process.
