Despite shrinking by US$77m in the past week, ImmunoGen (NASDAQ:IMGN) shareholders are still up 100% over 3 years

The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But if you buy shares in a really great company, you can more than double your money. For instance the ImmunoGen, Inc. (NASDAQ:IMGN) share price is 100% higher than it was three years ago. That sort of return is as solid as granite. It's also up 11% in about a month.

Since the long term performance has been good but there's been a recent pullback of 6.8%, let's check if the fundamentals match the share price.

Check out our latest analysis for ImmunoGen

ImmunoGen 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. When a company doesn't make profits, we'd generally expect to see good revenue growth. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

ImmunoGen's revenue trended up 31% each year over three years. That's well above most pre-profit companies. Along the way, the share price gained 26% per year, a solid pop by our standards. But it does seem like the market is paying attention to strong revenue growth. That's not to say we think the share price is too high. In fact, it might be worth keeping an eye on this one.

A Different Perspective

We regret to report that ImmunoGen shareholders are down 40% for the year. Unfortunately, that's worse than the broader market decline of 7.2%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. On the bright side, long term shareholders have made money, with a gain of 3% per year over half a decade. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
