SI-BONE, Inc. (NASDAQ:SIBN) shareholders should be happy to see the share price up 19% in the last month. But if you look at the last five years the returns have not been good. After all, the share price is down 20% in that time, significantly under-performing the market.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

Check out our latest analysis for SI-BONE

Because SI-BONE made a loss in the last twelve months, we think the market is probably more focussed on revenue and revenue growth, at least for now. Shareholders of unprofitable companies usually desire strong revenue growth. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

In the last half decade, SI-BONE saw its revenue increase by 19% per year. That's better than most loss-making companies. Shareholders are no doubt disappointed with the loss of 4%, each year, in that time. So you might argue the SI-BONE should get more credit for its rather impressive revenue growth over the period. If that's the case, now might be the smart time to take a close look at it.

A Different Perspective

SI-BONE shareholders are down 17% for the year, but the market itself is up 24%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 4% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business. It's always interesting to track share price performance over the longer term. But to understand SI-BONE better, we need to consider many other factors.
