As every investor would know, not every swing hits the sweet spot. But you want to avoid the really big losses like the plague. So consider, for a moment, the misfortune of PENN Entertainment, Inc. (NASDAQ:PENN) investors who have held the stock for three years as it declined a whopping 77%. That would certainly shake our confidence in the decision to own the stock.

Since shareholders are down over the longer term, lets look at the underlying fundamentals over the that time and see if they've been consistent with returns.

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

Over the three years that the share price declined, PENN Entertainment's earnings per share (EPS) dropped significantly, falling to a loss. Due to the loss, it's not easy to use EPS as a reliable guide to the business. However, we can say we'd expect to see a falling share price in this scenario.

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.

A Different Perspective

Investors in PENN Entertainment had a tough year, with a total loss of 12%, against a market gain of about 34%. However, keep in mind that even the best stocks will sometimes underperform the market over a twelve month period. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 2% over the last half decade. We realise that Baron Rothschild has said investors should "buy when there is blood on the streets", but we caution that investors should first be sure they are buying a high quality business.
