Unfortunately, investing is risky - companies can and do go bankrupt. But when you pick a company that is really flourishing, you can make more than 100%. For example, the Black Cat Syndicate Limited (ASX:BC8) share price had more than doubled in just one year - up 119%. It's also good to see the share price up 51% over the last quarter. The company reported its financial results recently; you can catch up on the latest numbers by reading our company report. Zooming out, the stock is actually down 12% in the last three years.

Since the stock has added AU$40m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

Black Cat Syndicate isn't currently profitable, so most analysts would look to revenue growth to get an idea of how fast the underlying business is growing. Generally speaking, companies without profits are expected to grow revenue every year, and at a good clip. 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.

In the last year Black Cat Syndicate saw its revenue grow by 158%. That's stonking growth even when compared to other loss-making stocks. And the share price has responded, gaining 119% as we previously mentioned. It's great to see strong revenue growth, but the question is whether it can be sustained. Given the positive sentiment around the stock we're cautious, but there's no doubt its worth watching.

The image below shows how earnings and revenue have tracked over time (if you click on the image you can see greater detail).

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

It's nice to see that Black Cat Syndicate shareholders have received a total shareholder return of 119% over the last year. Notably the five-year annualised TSR loss of 0.2% per year compares very unfavourably with the recent share price performance. This makes us a little wary, but the business might have turned around its fortunes. 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. Take risks, for example - Black Cat Syndicate has 4 warning signs (and 2 which are significant) we think you should know about.
