Let me try, bro,...

1848.HK : No WHT.

3988.HK : Yes, WHT of 10% imposed. B careful of the dps payout of this ctr - dps trend has been dropping the last few years.

0857.HK : Yes, WHT of 10% imposed. Dividend payout is not stable,... too many Special Dividends over the years,... implying volatility in payout,...
Please correct me if I am wrong in the above,.... I gathered the above from some observations, the best person to know would be someone who holds these shares till Ex-Date.

You are welcome, bro,....

Emm,... HSBC has dipped below 60.00 this morning, reaching a low of 59.750 this morning. The boat might be coming back,.... but I can't figure out yet the reason for this pullback,...

If Bank of China pays out a yield of, say 8.15%, then 8.15% - (10% of 8.15%) still gives out a good yield of 7.335%. At the current price of HSBC, the yield is below 7%. So,... coming from this angle, at this current moment, BOC's yield is better than HSBC's.

THere is one major consideration then,.... BOC pays out once a year ! But HSBC pays out 4 times a year !!!!!!!!!!
