SK hynix's (KRX:000660) investors will be pleased with their massive 359% return over the last five years

Buying shares in the best businesses can build meaningful wealth for you and your family. While the best companies are hard to find, but they can generate massive returns over long periods. For example, the SK hynix Inc. (KRX:000660) share price is up a whopping 332% in the last half decade, a handsome return for long term holders. If that doesn't get you thinking about long term investing, we don't know what will. It's also up 41% in about a month.

So let's assess the underlying fundamentals over the last 5 years and see if they've moved in lock-step with shareholder returns.

To quote Buffett, 'Ships will sail around the world but the Flat Earth Society will flourish. There will continue to be wide discrepancies between price and value in the marketplace...' One flawed but reasonable way to assess how sentiment around a company has changed is to compare the earnings per share (EPS) with the share price.

Over half a decade, SK hynix managed to grow its earnings per share at 66% a year. The EPS growth is more impressive than the yearly share price gain of 34% over the same period. So it seems the market isn't so enthusiastic about the stock these days. The reasonably low P/E ratio of 8.61 also suggests market apprehension.

What About Dividends?

When looking at investment returns, it is important to consider the difference between total shareholder return (TSR) and share price return. 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. It's fair to say that the TSR gives a more complete picture for stocks that pay a dividend. As it happens, SK hynix's TSR for the last 5 years was 359%, which exceeds the share price return mentioned earlier. The dividends paid by the company have thusly boosted the total shareholder return.

A Different Perspective

We're pleased to report that SK hynix shareholders have received a total shareholder return of 115% over one year. Of course, that includes the dividend. That gain is better than the annual TSR over five years, which is 36%. Therefore it seems like sentiment around the company has been positive lately. Given the share price momentum remains strong, it might be worth taking a closer look at the stock, lest you miss an opportunity.
