Investing in Greenbrook TMS (TSE:GTMS) a year ago would have delivered you a 76% gain

The simplest way to invest in stocks is to buy exchange traded funds. But investors can boost returns by picking market-beating companies to own shares in. For example, the Greenbrook TMS Inc. (TSE:GTMS) share price is up 76% in the last 1 year, clearly besting the market return of around 26% (not including dividends). If it can keep that out-performance up over the long term, investors will do very well! Note that businesses generally develop over the long term, so the returns over the last year might not reflect a long term trend.

So let's assess the underlying fundamentals over the last 1 year and see if they've moved in lock-step with shareholder returns.

Check out our latest analysis for Greenbrook TMS

Because Greenbrook TMS made a loss in the last twelve months, we think the market is probably more focussed on revenue and revenue growth, at least for now. Shareholders of unprofitable companies usually expect strong revenue growth. That's because fast revenue growth can be easily extrapolated to forecast profits, often of considerable size.

Greenbrook TMS grew its revenue by 11% last year. That's not a very high growth rate considering it doesn't make profits. In keeping with the revenue growth, the share price gained 76% in that time. While not a huge gain tht seems pretty reasonable. Given the market doesn't seem too excited about the stock, a closer look at the financial data could pay off, if you can find indications of a stronger growth trend in the future.

A Different Perspective

Greenbrook TMS shareholders should be happy with the total gain of 76% over the last twelve months. That's better than the more recent three month gain of 11%, implying that share price has plateaued recently. Having said that, we doubt shareholders would be concerned. It seems the market is simply waiting on more information, because if the business delivers so will the share price (eventually). 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.
