Many investors define successful investing as beating the market average over the long term. But its virtually certain that sometimes you will buy stocks that fall short of the market average returns. Unfortunately, that's been the case for longer term Teradata Corporation (NYSE:TDC) shareholders, since the share price is down 46% in the last three years, falling well short of the market return of around 26%. And the ride hasn't got any smoother in recent times over the last year, with the price 33% lower in that time. Shareholders have had an even rougher run lately, with the share price down 13% in the last 90 days.

With that in mind, it's worth seeing if the company's underlying fundamentals have been the driver of long term performance, or if there are some discrepancies.

To paraphrase Benjamin Graham: Over the short term the market is a voting machine, but over the long term it's a weighing machine. 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 the three years that the share price fell, Teradata's earnings per share (EPS) dropped by 11% each year. This reduction in EPS is slower than the 18% annual reduction in the share price. So it's likely that the EPS decline has disappointed the market, leaving investors hesitant to buy.

A Different Perspective

While the broader market gained around 36% in the last year, Teradata shareholders lost 33%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Longer term investors wouldn't be so upset, since they would have made 0.8%, 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.
