For many investors, the main point of stock picking is to generate higher returns than the overall market. But the risk of stock picking is that you will likely buy under-performing companies. We regret to report that long term Woolworths Group Limited (ASX:WOW) shareholders have had that experience, with the share price dropping 20% in three years, versus a market return of about 23%. Furthermore, it's down 13% in about a quarter. That's not much fun for holders.

So let's have a look and see if the longer term performance of the company has been in line with the underlying business' progress.

There is no denying that markets are sometimes efficient, but prices do not always reflect underlying business performance. 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.

Woolworths Group saw its EPS decline at a compound rate of 58% per year, over the last three years. This fall in the EPS is worse than the 7% compound annual share price fall. So the market may not be too worried about the EPS figure, at the moment -- or it may have previously priced some of the drop in. With a P/E ratio of 345.83, it's fair to say the market sees a brighter future for the business.

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?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. The TSR is a return calculation that accounts for the value of cash dividends (assuming that any dividend received was reinvested) and the calculated value of any discounted capital raisings and spin-offs. Arguably, the TSR gives a more comprehensive picture of the return generated by a stock. We note that for Woolworths Group the TSR over the last 3 years was -11%, which is better than the share price return mentioned above. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Woolworths Group shareholders are down 12% for the year (even including dividends), but the market itself is up 15%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. On the bright side, long term shareholders have made money, with a gain of 2% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. While it is well worth considering the different impacts that market conditions can have on the share price, there are other factors that are even more important.
