It's not possible to invest over long periods without making some bad investments. But you have a problem if you face massive losses more than once in a while. So take a moment to sympathize with the long term shareholders of Beam Global (NASDAQ:BEEM), who have seen the share price tank a massive 82% over a three year period. That would certainly shake our confidence in the decision to own the stock. The more recent news is of little comfort, with the share price down 32% in a year. 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.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

View our latest analysis for Beam Global

Beam Global 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 hope to see good revenue growth. Some companies are willing to postpone profitability to grow revenue faster, but in that case one would hope for good top-line growth to make up for the lack of earnings.

Over three years, Beam Global grew revenue at 75% per year. That is faster than most pre-profit companies. So on the face of it we're really surprised to see the share price down 22% a year in the same time period. You'd want to take a close look at the balance sheet, as well as the losses. Sometimes fast revenue growth doesn't lead to profits. Unless the balance sheet is strong, the company might have to raise capital.

A Different Perspective

Beam Global shareholders are down 32% for the year, but the market itself is up 35%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 4% over the last half decade. 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.
