Investors in CytomX Therapeutics (NASDAQ:CTMX) have unfortunately lost 90% over the last five years

In this article:

CytomX Therapeutics, Inc. (NASDAQ:CTMX) shareholders should be happy to see the share price up 26% in the last month. But will that repair the damage for the weary investors who have owned this stock as it declined over half a decade? Probably not. Five years have seen the share price descend precipitously, down a full 90%. The recent bounce might mean the long decline is over, but we are not confident. The real question is whether the business can leave its past behind and improve itself over the years ahead. 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.

It's worthwhile assessing if the company's economics have been moving in lockstep with these underwhelming shareholder returns, or if there is some disparity between the two. So let's do just that.

View our latest analysis for CytomX Therapeutics

Because CytomX Therapeutics 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 expect strong revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one does expect good top-line growth.

In the last five years CytomX Therapeutics saw its revenue shrink by 3.2% per year. That's not what investors generally want to see. If a business loses money, you want it to grow, so no surprises that the share price has dropped 14% each year in that time. It takes a certain kind of mental fortitude (or recklessness) to buy shares in a company that loses money and doesn't grow revenue. That is not really what the successful investors we know aim for.

A Different Perspective

Investors in CytomX Therapeutics had a tough year, with a total loss of 4.5%, against a market gain of about 18%. 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. Unfortunately, longer term shareholders are suffering worse, given the loss of 14% doled out over the last five years. 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.
