Investors in Aemetis (NASDAQ:AMTX) have made a massive return of 861% over the past three years

Some Aemetis, Inc. (NASDAQ:AMTX) shareholders are probably rather concerned to see the share price fall 43% over the last three months. But that doesn't change the fact that the returns over the last three years have been spectacular. Over that time, we've been excited to watch the share price climb an impressive 861%. As long term investors the recent fall doesn't detract all that much from the longer term story. The thing to consider is whether there is still too much elation around the company's prospects. We love happy stories like this one. The company should be really proud of that performance!

So let's investigate and see if the longer term performance of the company has been in line with the underlying business' progress.

Check out our latest analysis for Aemetis

Aemetis 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. Some companies are willing to postpone profitability to grow revenue faster, but in that case one does expect good top-line growth.

Aemetis' revenue trended up 0.5% each year over three years. Considering the company is losing money, we think that rate of revenue growth is uninspiring. So we're surprised that the share price has soared by 113% each year over that time. A win is a win, even if the revenue growth doesn't really explain it, in our view). Shareholders would want to be sure that the share price rise is sustainable.

A Different Perspective

We're pleased to report that Aemetis shareholders have received a total shareholder return of 187% over one year. That gain is better than the annual TSR over five years, which is 45%. Therefore it seems like sentiment around the company has been positive lately. In the best case scenario, this may hint at some real business momentum, implying that now could be a great time to delve deeper. 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. Even so, be aware that Aemetis is showing 4 warning signs in our investment analysis , and 3 of those are a bit concerning...
