The worst result, after buying shares in a company (assuming no leverage), would be if you lose all the money you put in. But if you buy shares in a really great company, you can more than double your money. For example, the Raiz Invest Limited (ASX:RZI) share price has soared 270% in the last three years. That sort of return is as solid as granite. We note the stock price is up 1.4% in the last seven days.

Let's take a look at the underlying fundamentals over the longer term, and see if they've been consistent with shareholders returns.

Given that Raiz Invest didn't make a profit in the last twelve months, we'll focus on revenue growth to form a quick view of its business development. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

Over the last three years Raiz Invest has grown its revenue at 46% annually. That's well above most pre-profit companies. Along the way, the share price gained 55% 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 Raiz Invest is still worth investigating - successful businesses can often keep growing for long periods.
