Simply Wall St · 2d ago

Many investors define successful investing as beating the market average over the long term. But its virtually certain that sometimes you will buy stocks that fall short of the market average returns. We regret to report that long term Genscript Biotech Corporation (HKG:1548) shareholders have had that experience, with the share price dropping 40% in three years, versus a market return of about 54%. Shareholders have had an even rougher run lately, with the share price down 23% in the last 90 days.

Given the past week has been tough on shareholders, let's investigate the fundamentals and see what we can learn.

While Genscript Biotech made a small profit, in the last year, we think that the market is probably more focussed on the top line growth at the moment. As a general rule, we think this kind of company is more comparable to loss-making stocks, since the actual profit is so low. For shareholders to have confidence a company will grow profits significantly, it must grow revenue.

Over three years, Genscript Biotech grew revenue at 4.1% per year. That's not a very high growth rate considering it doesn't make profits. The stock dropped 12% during that time. Shareholders will probably be hoping growth picks up soon. But the real upside for shareholders will be if the company can start generating profits.

A Different Perspective

Genscript Biotech's TSR for the year was broadly in line with the market average, at 31%. That gain looks pretty satisfying, and it is even better than the five-year TSR of 2% per year. Even if the share price growth slows down from here, there's a good chance that this is business worth watching in the long term. 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.
