Cosmo Chemical (KRX:005420) jumps 22% this week, taking five-year gains to 146%

The most you can lose on any stock (assuming you don't use leverage) is 100% of your money. But on the bright side, if you buy shares in a high quality company at the right price, you can gain well over 100%. For example, the Cosmo Chemical Co., Ltd. (KRX:005420) share price has soared 137% in the last half decade. Most would be very happy with that. And in the last month, the share price has gained 27%.

After a strong gain in the past week, it's worth seeing if longer term returns have been driven by improving fundamentals.

See our latest analysis for Cosmo Chemical

Cosmo Chemical wasn't profitable in the last twelve months, it is unlikely we'll see a strong correlation between its share price and its earnings per share (EPS). Arguably revenue is our next best option. Shareholders of unprofitable companies usually desire strong revenue growth. As you can imagine, fast revenue growth, when maintained, often leads to fast profit growth.

In the last 5 years Cosmo Chemical saw its revenue grow at 18% per year. That's well above most pre-profit companies. Meanwhile, its share price performance certainly reflects the strong growth, given the share price grew at 19% per year, compound, during the period. This suggests the market has well and truly recognized the progress the business has made. Cosmo Chemical seems like a high growth stock - so growth investors might want to add it to their watchlist.

What About The Total Shareholder Return (TSR)?

Investors should note that there's a difference between Cosmo Chemical's total shareholder return (TSR) and its share price change, which we've covered above. The TSR attempts to capture the value of dividends (as if they were reinvested) as well as any spin-offs or discounted capital raisings offered to shareholders. We note that Cosmo Chemical's TSR, at 146% is higher than its share price return of 137%. When you consider it hasn't been paying a dividend, this data suggests shareholders have benefitted from a spin-off, or had the opportunity to acquire attractively priced shares in a discounted capital raising.

A Different Perspective

We regret to report that Cosmo Chemical shareholders are down 29% for the year. Unfortunately, that's worse than the broader market decline of 5.6%. However, it could simply be that the share price has been impacted by broader market jitters. It might be worth keeping an eye on the fundamentals, in case there's a good opportunity. On the bright side, long term shareholders have made money, with a gain of 20% per year over half a decade. If the fundamental data continues to indicate long term sustainable growth, the current sell-off could be an opportunity worth considering. I find it very interesting to look at share price over the long term as a proxy for business performance. But to truly gain insight, we need to consider other information, too.
