It's easy to match the overall market return by buying an index fund. While individual stocks can be big winners, plenty more fail to generate satisfactory returns. Unfortunately the RPC, Inc. (NYSE:RES) share price slid 17% over twelve months. That's well below the market return of 23%. Longer term investors have fared much better, since the share price is up 6.7% in three years. It's down 21% in about a quarter.

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

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 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.

Unfortunately RPC reported an EPS drop of 45% for the last year. The share price fall of 17% isn't as bad as the reduction in earnings per share. So despite the weak per-share profits, some investors are probably relieved the situation wasn't more difficult.

A Different Perspective

While the broader market gained around 23% in the last year, RPC shareholders lost 15% (even including dividends). 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. It's always interesting to track share price performance over the longer term. But to understand RPC better, we need to consider many other factors.
