Sutro Biopharma (NASDAQ:STRO) shareholders are up 11% this past week, but still in the red over the last three years

In this article:

It's nice to see the Sutro Biopharma, Inc. (NASDAQ:STRO) share price up 11% in a week. But the last three years have seen a terrible decline. In that time the share price has melted like a snowball in the desert, down 83%. Arguably, the recent bounce is to be expected after such a bad drop. But the more important question is whether the underlying business can justify a higher price still. 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.

The recent uptick of 11% could be a positive sign of things to come, so let's take a look at historical fundamentals.

Given that Sutro Biopharma 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. Shareholders of unprofitable companies usually expect strong revenue growth. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

Over three years, Sutro Biopharma grew revenue at 14% per year. That's a pretty good rate of top-line growth. So it's hard to believe the share price decline of 22% per year is due to the revenue. More likely, the market was spooked by the cost of that revenue. This is exactly why investors need to diversify - even when a loss making company grows revenue, it can fail to deliver for shareholders.

A Different Perspective

Sutro Biopharma shareholders are down 61% for the year, but the market itself is up 16%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 12% per year over five years. 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. Consider for instance, the ever-present spectre of investment risk. We've identified 4 warning signs with Sutro Biopharma , and understanding them should be part of your investment process.
