It's nice to see the Gevo, Inc. (NASDAQ:GEVO) share price up 11% in a week. But the last three years have seen a terrible decline. The share price has sunk like a leaky ship, down 89% in that time. So we're relieved for long term holders to see a bit of uplift. But the more important question is whether the underlying business can justify a higher price still. We really hope anyone holding through that price crash has a diversified portfolio. Even when you lose money, you don't have to lose the lesson.

On a more encouraging note the company has added US$15m to its market cap in just the last 7 days, so let's see if we can determine what's driven the three-year loss for shareholders.

Gevo 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. Shareholders of unprofitable companies usually desire strong revenue growth. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

Over three years, Gevo grew revenue at 86% per year. That's well above most other pre-profit companies. So why has the share priced crashed 24% per year, in the same time? The share price makes us wonder if there is an issue with profitability. Ultimately, revenue growth doesn't amount to much if the business can't scale well. Unless the balance sheet is strong, the company might have to raise capital.

A Different Perspective

Investors in Gevo had a tough year, with a total loss of 42%, against a market gain of about 26%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Regrettably, last year's performance caps off a bad run, with the shareholders facing a total loss of 11% per year over five years. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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.
