Passive investing in index funds can generate returns that roughly match the overall market. But you can significantly boost your returns by picking above-average stocks. To wit, the Marinus Pharmaceuticals, Inc. (NASDAQ:MRNS) share price is 71% higher than it was a year ago, much better than the market return of around 13% (not including dividends) in the same period. So that should have shareholders smiling. It is also impressive that the stock is up 45% over three years, adding to the sense that it is a real winner.

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders returns.

Because Marinus Pharmaceuticals 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 year Marinus Pharmaceuticals saw its revenue shrink by 22%. The stock is up 71% in that time, a fine performance given the revenue drop. To us that means that there isn't a lot of correlation between the past revenue performance and the share price, but a closer look at analyst forecasts and the bottom line may well explain a lot.

A Different Perspective

It's good to see that Marinus Pharmaceuticals has rewarded shareholders with a total shareholder return of 71% in the last twelve months. There's no doubt those recent returns are much better than the TSR loss of 11% per year over five years. We generally put more weight on the long term performance over the short term, but the recent improvement could hint at a (positive) inflection point within the business. 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.
