Despite shrinking by JP¥7.7b in the past week, Sanken Electric (TSE:6707) shareholders are still up 291% over 5 years

When you buy shares in a company, it's worth keeping in mind the possibility that it could fail, and you could lose your money. But on the bright side, you can make far more than 100% on a really good stock. For instance, the price of Sanken Electric Co., Ltd. (TSE:6707) stock is up an impressive 287% over the last five years. On top of that, the share price is up 21% in about a quarter.

While the stock has fallen 4.4% this week, it's worth focusing on the longer term and seeing if the stocks historical returns have been driven by the underlying fundamentals.

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 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.

During the five years of share price growth, Sanken Electric moved from a loss to profitability. That kind of transition can be an inflection point that justifies a strong share price gain, just as we have seen here. Given that the company made a profit three years ago, but not five years ago, it is worth looking at the share price returns over the last three years, too. Indeed, the Sanken Electric share price has gained 38% in three years. Meanwhile, EPS is up 271% per year. This EPS growth is higher than the 11% average annual increase in the share price over the same three years. Therefore, it seems the market has moderated its expectations for growth, somewhat. This cautious sentiment is reflected in its (fairly low) P/E ratio of 4.38.

It is of course excellent to see how Sanken Electric has grown profits over the years, but the future is more important for shareholders. Take a more thorough look at Sanken Electric's financial health with this free report on its balance sheet.

What About The Total Shareholder Return (TSR)?

We'd be remiss not to mention the difference between Sanken Electric's total shareholder return (TSR) and its share price return. Arguably the TSR is a more complete return calculation because it accounts for the value of dividends (as if they were reinvested), along with the hypothetical value of any discounted capital that have been offered to shareholders. Dividends have been really beneficial for Sanken Electric shareholders, and that cash payout contributed to why its TSR of 291%, over the last 5 years, is better than the share price return.

A Different Perspective

It's nice to see that Sanken Electric shareholders have received a total shareholder return of 6.3% over the last year. However, the TSR over five years, coming in at 31% per year, is even more impressive. The pessimistic view would be that be that the stock has its best days behind it, but on the other hand the price might simply be moderating while the business itself continues to execute. It's always interesting to track share price performance over the longer term. But to understand Sanken Electric better, we need to consider many other factors.
