Marinus Pharmaceuticals adds $24 million to its market cap, but investors are still down 88% from five years ago


It’s nice to see the Marinus Pharmaceuticals, Inc. (NASDAQ:MRNS) stock price up 14% in one week. But spare a thought for long-term holders, who have held the stock as it has fallen in value for the past five years. Like a sinking ship, the stock price fell 88% during this period. It’s true that the recent rebound could signal that the company is turning over a new leaf, but we’re not so sure. The important question is whether the company itself justifies a higher share price in the long term. We really hope that anyone weathering this price drop has a diversified portfolio. Even when you lose money, you don’t have to lose the lesson.

While the past five years have been difficult for Marinus Pharmaceuticals shareholders, the past week has shown promising signs. So let’s take a look at the longer-term fundamentals and see if they were the driver of the negative returns.

Check out our latest analysis for Marinus Pharmaceuticals

Since Marinus Pharmaceuticals has not made a profit in the past twelve months, we will focus on revenue growth to get a quick overview of its business development. Generally speaking, companies without profits should increase their revenue every year, and at a good pace. Indeed, it is difficult to be sure that a business will be sustainable if revenue growth is negligible and it never makes a profit.

Over the past five years, Marinus Pharmaceuticals has seen its revenue increase by 85% per year. That’s way above most other nonprofits. So on the face of it, we’re really surprised to see that the stock price has fallen by an average of 13% every year over the same period. It could be that the stock has been over hyped before. While there may be an opportunity here, you would want to take a close look at the strength of the balance sheet.

A different perspective

While the broader market lost around 22% in the twelve months, Marinus Pharmaceuticals shareholders fared even worse, losing 66%. That said, it is inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Unfortunately, last year’s performance capped a bad run, with shareholders facing a total loss of 13% per year over five years. Generally speaking, long-term stock price weakness can be a bad sign, although contrarian investors may want to seek out the stock in hopes of a turnaround. It is always interesting to follow the evolution of the share price over the long term. But to better understand Marinus Pharmaceuticals, we need to consider many other factors.
