Y-mAbs Therapeutics, Inc. (NASDAQ:YMAB) shareholders will doubtless be very grateful to see the share price up 36% in the last quarter. But only the myopic could ignore the astounding decline over three years. To wit, the share price sky-dived 85% in that time. So we're relieved for long term holders to see a bit of uplift. But the more important question is whether the underlying business can justify a higher price still. 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 stock has risen 17% in the past week but long term shareholders are still in the red, let's see what the fundamentals can tell us.

Check out our latest analysis for Y-mAbs Therapeutics

Given that Y-mAbs Therapeutics didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. 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, Y-mAbs Therapeutics saw its revenue grow by 55% per year, compound. That's well above most other pre-profit companies. So why has the share priced crashed 23% per year, in the same time? You'd want to take a close look at the balance sheet, as well as the losses. Sometimes fast revenue growth doesn't lead to profits. If the company is low on cash, it may have to raise capital soon.

A Different Perspective

It's good to see that Y-mAbs Therapeutics has rewarded shareholders with a total shareholder return of 57% in the last twelve months. That certainly beats the loss of about 10% per year over the last half decade. This makes us a little wary, but the business might have turned around its fortunes. It's always interesting to track share price performance over the longer term. But to understand Y-mAbs Therapeutics better, we need to consider many other factors.
