Some Geron Corporation (NASDAQ:GERN) shareholders are probably rather concerned to see the share price fall 32% over the last three months. But in three years the returns have been great. Indeed, the share price is up a very strong 188% in that time. After a run like that some may not be surprised to see prices moderate. The fundamental business performance will ultimately dictate whether the top is in, or if this is a stellar buying opportunity.

Now it's worth having a look at the company's fundamentals too, because that will help us determine if the long term shareholder return has matched the performance of the underlying business.

Geron isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. When a company doesn't make profits, we'd generally hope to see good revenue growth. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

In the last 3 years Geron saw its revenue grow at 119% per year. That's much better than most loss-making companies. Along the way, the share price gained 42% per year, a solid pop by our standards. This suggests the market has recognized the progress the business has made, at least to a significant degree. Nonetheless, we'd say Geron is still worth investigating - successful businesses can often keep growing for long periods.
