Dollar Tree (NASDAQ:DLTR) shareholders have endured a 23% loss from investing in the stock a year ago

Passive investing in an index fund is a good way to ensure your own returns roughly match the overall market. Active investors aim to buy stocks that vastly outperform the market - but in the process, they risk under-performance. That downside risk was realized by Dollar Tree, Inc. (NASDAQ:DLTR) shareholders over the last year, as the share price declined 23%. That's disappointing when you consider the market returned 27%. On the other hand, the stock is actually up 3.6% over three years. The falls have accelerated recently, with the share price down 13% in the last three months.

Now let's have a look at the company's fundamentals, and see if the long term shareholder return has matched the performance of the underlying business.

While the efficient markets hypothesis continues to be taught by some, it has been proven that markets are over-reactive dynamic systems, and investors are not always rational. One way to examine how market sentiment has changed over time is to look at the interaction between a company's share price and its earnings per share (EPS).

Dollar Tree fell to a loss making position during the year. Buyers no doubt think it's a temporary situation, but those with a nose for quality have low tolerance for losses. We hope for shareholders' sake that the company becomes profitable again soon.

It's good to see that there was some significant insider buying in the last three months. That's a positive. That said, we think earnings and revenue growth trends are even more important factors to consider.

A Different Perspective

Investors in Dollar Tree had a tough year, with a total loss of 23%, against a market gain of about 27%. 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 4%, 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.
