Flat Glass Group (HKG:6865) adds HK$909m to market cap in the past 7 days, though investors from three years ago are still down 39%

It is a pleasure to report that the Flat Glass Group Co., Ltd. (HKG:6865) is up 50% in the last quarter. But that doesn't help the fact that the three year return is less impressive. Truth be told the share price declined 44% in three years and that return, Dear Reader, falls short of what you could have got from passive investing with an index fund.

The recent uptick of 3.3% could be a positive sign of things to come, so let's take a look at historical fundamentals.

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. 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.

Flat Glass Group saw its share price decline over the three years in which its EPS also dropped, falling to a loss. This was, in part, due to extraordinary items impacting earnings. Due to the loss, it's not easy to use EPS as a reliable guide to the business. But it's safe to say we'd generally expect the share price to be lower as a result!

We like that insiders have been buying shares in the last twelve months. Having said that, most people consider earnings and revenue growth trends to be a more meaningful guide to the business.

What About The Total Shareholder Return (TSR)?

We've already covered Flat Glass Group's share price action, but we should also mention its total shareholder return (TSR). 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 Flat Glass Group shareholders, and that cash payout explains why its total shareholder loss of 39%, over the last 3 years, isn't as bad as the share price return.

A Different Perspective

Flat Glass Group provided a TSR of 43% over the last twelve months. But that was short of the market average. On the bright side, that's still a gain, and it is certainly better than the yearly loss of about 2% endured over half a decade. It could well be that the business is stabilizing. 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.
