Payout ratios

Dividends are typically paid from company earnings. If a company pays more in dividends than it earned, then the dividend might become unsustainable - hardly an ideal situation. So we need to form a view on if a company's dividend is sustainable, relative to its net profit after tax. In the last year, China Zheshang Bank paid out 38% of its profit as dividends. This is a middling range that strikes a nice balance between paying dividends to shareholders, and retaining enough earnings to invest in future growth. One of the risks is that management reinvests the retained capital poorly instead of paying a higher dividend.

Dividend Volatility

One of the major risks of relying on dividend income, is the potential for a company to struggle financially and cut its dividend. Not only is your income cut, but the value of your investment declines as well - nasty. Looking at the data, we can see that China Zheshang Bank has been paying a dividend for the past four years. This company's dividend has been unstable, and with a relatively short history, we think it's a little soon to draw strong conclusions about its long term dividend potential. During the past four-year period, the first annual payment was CN¥0.13 in 2016, compared to CN¥0.24 last year. Dividends per share have grown at approximately 17% per year over this time. China Zheshang Bank's dividend payments have fluctuated, so it hasn't grown 17% every year, but the CAGR is a useful rule of thumb for approximating the historical growth.

It's not great to see that the payment has been cut in the past. We're generally more wary of companies that have cut their dividend before, as they tend to perform worse in an economic downturn.
