It is a pleasure to report that the Silk Road Medical, Inc (NASDAQ:SILK) is up 49% in the last quarter. Meanwhile over the last three years the stock has dropped hard. Tragically, the share price declined 66% in that time. So it is really good to see an improvement. The rise has some hopeful, but turnarounds are often precarious.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

Because Silk Road Medical 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. When a company doesn't make profits, we'd generally hope to see good revenue growth. 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.

In the last three years, Silk Road Medical saw its revenue grow by 29% per year, compound. That's well above most other pre-profit companies. In contrast, the share price is down 18% compound, over three years - disappointing by most standards. This could mean hype has come out of the stock because the losses are concerning investors. But a share price drop of that magnitude could well signal that the market is overly negative on the stock.

The company's revenue and earnings (over time) are depicted in the image below (click to see the exact numbers).

It's probably worth noting we've seen significant insider buying in the last quarter, which we consider a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business.

A Different Perspective

Investors in Silk Road Medical had a tough year, with a total loss of 57%, against a market gain of about 27%. 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 9% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
