Even after rising 48% this past week, Personalis (NASDAQ:PSNL) shareholders are still down 89% over the past three years

In this article:

This month, we saw the Personalis, Inc. (NASDAQ:PSNL) up an impressive 94%. But only the myopic could ignore the astounding decline over three years. Indeed, the share price is down a whopping 89% in the last three years. So it's about time shareholders saw some gains. Of course the real question is whether the business can sustain a turnaround. 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.

While the last three years has been tough for Personalis shareholders, this past week has shown signs of promise. So let's look at the longer term fundamentals and see if they've been the driver of the negative returns.

Check out our latest analysis for Personalis

Personalis wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. That's because it's hard to be confident a company will be sustainable if revenue growth is negligible, and it never makes a profit.

In the last three years Personalis saw its revenue shrink by 6.7% per year. That is not a good result. Having said that the 24% annualized share price decline highlights the risk of investing in unprofitable companies. We're generally averse to companies with declining revenues, but we're not alone in that. There's no more than a snowball's chance in hell that share price will head back to its old highs, in the short term.

A Different Perspective

Personalis shareholders are up 8.9% for the year. But that was short of the market average. But at least that's still a gain! Over five years the TSR has been a reduction of 13% per year, over five years. It could well be that the business is stabilizing. It's always interesting to track share price performance over the longer term. But to understand Personalis better, we need to consider many other factors.
