Investors in Gritstone bio (NASDAQ:GRTS) have unfortunately lost 66% over the last three years

In this article:

It is doubtless a positive to see that the Gritstone bio, Inc. (NASDAQ:GRTS) share price has gained some 32% in the last three months. But that is small recompense for the exasperating returns over three years. Tragically, the share price declined 66% in that time. Some might say the recent bounce is to be expected after such a bad drop. Perhaps the company has turned over a new leaf.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

Gritstone bio isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Shareholders of unprofitable companies usually expect strong revenue growth. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last three years, Gritstone bio saw its revenue grow by 51% per year, compound. That is faster than most pre-profit companies. In contrast, the share price is down 19% compound, over three years - disappointing by most standards. This could mean hype has come out of the stock because the losses are concerning investors. When we see revenue growth, paired with a falling share price, we can't help wonder if there is an opportunity for those who are willing to dig deeper.

A Different Perspective

The last twelve months weren't great for Gritstone bio shares, which performed worse than the market, costing holders 37%. The market shed around 7.9%, no doubt weighing on the stock price. The three-year loss of 19% per year isn't as bad as the last twelve months, suggesting that the company has not been able to convince the market it has solved its problems. Although Baron Rothschild famously said to "buy when there's blood in the streets, even if the blood is your own", he also focusses on high quality stocks with solid prospects. 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.
