The Proteostasis Therapeutics (NASDAQ:PTI) Share Price Is Down 84% So Some Shareholders Are Rather Upset

Proteostasis Therapeutics, Inc. (NASDAQ:PTI) shareholders will doubtless be very grateful to see the share price up 169% in the last quarter. But that doesn't change the fact that the returns over the last three years have been stomach churning. The share price has sunk like a leaky ship, down 84% in that time. Arguably, the recent bounce is to be expected after such a bad drop. Only time will tell if the company can sustain the 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.

Proteostasis Therapeutics 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. 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.

Over the last three years, Proteostasis Therapeutics's revenue dropped 16% per year. That's definitely a weaker result than most pre-profit companies report. The swift share price decline at an annual compound rate of 45%, reflects this weak fundamental performance. We prefer leave it to clowns to try to catch falling knives, like this stock. There is a good reason that investors often describe buying a sharply falling stock price as 'trying to catch a falling knife'. Think about it.

A Different Perspective

Proteostasis Therapeutics shareholders are down 43% for the year, but the broader market is up 27%. Of course the long term matters more than the short term, and even great stocks will sometimes have a poor year. However, the loss over the last year isn't as bad as the 45% per annum loss investors have suffered over the last three years. We'd need clear signs of growth in the underlying business before we could muster much enthusiasm for this one. You might want to assess this data-rich visualization of its earnings, revenue and cash flow.
