Many investors define successful investing as beating the market average over the long term. But the risk of stock picking is that you will likely buy under-performing companies. Unfortunately, that's been the case for longer term TELUS Corporation (TSE:T) shareholders, since the share price is down 28% in the last three years, falling well short of the market return of around 22%.

If the past week is anything to go by, investor sentiment for TELUS isn't positive, so let's see if there's a mismatch between fundamentals and the share price.

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 three years that the share price fell, TELUS' earnings per share (EPS) dropped by 18% each year. In comparison the 10% compound annual share price decline isn't as bad as the EPS drop-off. This suggests that the market retains some optimism around long term earnings stability, despite past EPS declines.

It's good to see that there was some significant insider buying in the last three months. That's a positive. On the other hand, we think the revenue and earnings trends are much more meaningful measures of the business.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. 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. We note that for TELUS the TSR over the last 3 years was -15%, which is better than the share price return mentioned above. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

Investors in TELUS had a tough year, with a total loss of 5.7% (including dividends), against a market gain of about 29%. Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Longer term investors wouldn't be so upset, since they would have made 1.5%, each year, over five years. It could be that the recent sell-off is an opportunity, so it may be worth checking the fundamental data for signs of a long term growth trend. 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.
