We think all investors should try to buy and hold high quality multi-year winners. And highest quality companies can see their share prices grow by huge amounts. Don't believe it? Then look at the Signet Jewelers Limited (NYSE:SIG) share price. It's 357% higher than it was five years ago. If that doesn't get you thinking about long term investing, we don't know what will. On top of that, the share price is up 19% in about a quarter. But this could be related to the strong market, which is up 14% in the last three months.

While this past week has detracted from the company's five-year return, let's look at the recent trends of the underlying business and see if the gains have been in alignment.

While markets are a powerful pricing mechanism, share prices reflect investor sentiment, not just underlying business performance. 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 last half decade, Signet Jewelers became profitable. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here.

We know that Signet Jewelers has improved its bottom line lately, but is it going to grow revenue? Check if analysts think Signet Jewelers will grow revenue in the future.

What About Dividends?

It is important to consider the total shareholder return, as well as the share price return, for any given stock. Whereas the share price return only reflects the change in the share price, the TSR includes the value of dividends (assuming they were reinvested) and the benefit of any discounted capital raising or spin-off. So for companies that pay a generous dividend, the TSR is often a lot higher than the share price return. As it happens, Signet Jewelers' TSR for the last 5 years was 383%, which exceeds the share price return mentioned earlier. And there's no prize for guessing that the dividend payments largely explain the divergence!

A Different Perspective

Signet Jewelers shareholders are down 4.5% for the year (even including dividends), but the market itself is up 34%. 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 37%, 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. 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 risks, for instance.
