Investors three-year losses continue as Sealed Air (NYSE:SEE) dips a further 8.4% this week, earnings continue to decline

If you are building a properly diversified stock portfolio, the chances are some of your picks will perform badly. But the last three years have been particularly tough on longer term Sealed Air Corporation (NYSE:SEE) shareholders. Regrettably, they have had to cope with a 60% drop in the share price over that period. The falls have accelerated recently, with the share price down 20% in the last three months. But this could be related to the weak market, which is down 11% in the same period.

After losing 8.4% this past week, it's worth investigating the company's fundamentals to see what we can infer from past performance.

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).

During the three years that the share price fell, Sealed Air's earnings per share (EPS) dropped by 17% each year. The share price decline of 26% is actually steeper than the EPS slippage. So it seems the market was too confident about the business, in the past.

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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. In the case of Sealed Air, it has a TSR of -57% for the last 3 years. That exceeds its share price return that we previously mentioned. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

While the broader market gained around 4.8% in the last year, Sealed Air shareholders lost 17% (even including dividends). Even the share prices of good stocks drop sometimes, but we want to see improvements in the fundamental metrics of a business, before getting too interested. Unfortunately, last year's performance may indicate unresolved challenges, given that it was worse than the annualised loss of 0.8% over the last half decade. Generally speaking long term share price weakness can be a bad sign, though contrarian investors might want to research the stock in hope of a turnaround. 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. Consider for instance, the ever-present spectre of investment risk. We've identified 1 warning sign with Sealed Air , and understanding them should be part of your investment process.
