Sourcebio International (LON:SBI) shareholders have endured a 23% loss from investing in the stock a year ago

Passive investing in an index fund is a good way to ensure your own returns roughly match the overall market. While individual stocks can be big winners, plenty more fail to generate satisfactory returns. For example, the Sourcebio International Plc (LON:SBI) share price is down 23% in the last year. That's well below the market decline of 4.5%. Because Sourcebio International hasn't been listed for many years, the market is still learning about how the business performs.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One imperfect but simple way to consider how the market perception of a company has shifted is to compare the change in the earnings per share (EPS) with the share price movement.

During the unfortunate twelve months during which the Sourcebio International share price fell, it actually saw its earnings per share (EPS) improve by 324%. Of course, the situation might betray previous over-optimism about growth.

It's fair to say that the share price does not seem to be reflecting the EPS growth. So it's easy to justify a look at some other metrics.

Sourcebio International managed to grow revenue over the last year, which is usually a real positive. Since we can't easily explain the share price movement based on these metrics, it might be worth considering how market sentiment has changed towards the stock.

We consider it positive that insiders have made significant purchases in the last year. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

A Different Perspective

We doubt Sourcebio International shareholders are happy with the loss of 23% over twelve months. That falls short of the market, which lost 4.5%. That's disappointing, but it's worth keeping in mind that the market-wide selling wouldn't have helped. With the stock down 2.0% over the last three months, the market doesn't seem to believe that the company has solved all its problems. Basically, most investors should be wary of buying into a poor-performing stock, unless the business itself has clearly improved. It is all well and good that insiders have been buying shares, but we suggest you check here to see what price insiders were buying at.
