Investors in Zai Lab (NASDAQ:ZLAB) from three years ago are still down 51%, even after 5.7% gain this past week

Zai Lab Limited (NASDAQ:ZLAB) shareholders should be happy to see the share price up 11% in the last month. But that doesn't change the fact that the returns over the last three years have been disappointing. In that time, the share price dropped 51%. So the improvement may be a real relief to some. After all, could be that the fall was overdone.

Although the past week has been more reassuring for shareholders, they're still in the red over the last three years, so let's see if the underlying business has been responsible for the decline.

Zai Lab 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, Zai Lab saw its revenue grow by 31% per year, compound. That is faster than most pre-profit companies. The share price has moved in quite the opposite direction, down 15% over that time, a bad result. It seems likely that the market is worried about the continual losses. But a share price drop of that magnitude could well signal that the market is overly negative on the stock.

A Different Perspective

It's good to see that Zai Lab has rewarded shareholders with a total shareholder return of 41% in the last twelve months. Notably the five-year annualised TSR loss of 8% per year compares very unfavourably with the recent share price performance. 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.
