One simple way to benefit from the stock market is to buy an index fund. But if you pick the right individual stocks, you could make more than that. Just take a look at Drax Group plc (LON:DRX), which is up 31%, over three years, soundly beating the market return of 3.5% (not including dividends).

Since the stock has added UK£185m to its market cap in the past week alone, let's see if underlying performance has been driving long-term returns.

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...' By comparing earnings per share (EPS) and share price changes over time, we can get a feel for how investor attitudes to a company have morphed over time.

During three years of share price growth, Drax Group moved from a loss to profitability. So we would expect a higher share price over the period.

The image below shows how EPS has 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. Even so, future earnings will be far more important to whether current shareholders make money. This free interactive report on Drax Group's earnings, revenue and cash flow is a great place to start, if you want to investigate the stock further.

What About Dividends?

As well as measuring the share price return, investors should also consider the total shareholder return (TSR). The TSR incorporates the value of any spin-offs or discounted capital raisings, along with any dividends, based on the assumption that the dividends are reinvested. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. In the case of Drax Group, it has a TSR of 46% for the last 3 years. That exceeds its share price return that we previously mentioned. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

We regret to report that Drax Group shareholders are down 22% for the year (even including dividends). Unfortunately, that's worse than the broader market decline of 1.0%. Having said that, it's inevitable that some stocks will be oversold in a falling market. The key is to keep your eyes on the fundamental developments. Longer term investors wouldn't be so upset, since they would have made 9%, each year, over five years. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. 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.
