Yes.
For long term investors that bought at low price. 005 enjoys good stability, steady and long term growth, with generous interest return.
No.
For short term speculators, since the opportunity cost of 005 is too high especially in recent months. The interest from 005 is far lower than the gains from stocks elsewhere.
I sold all my 005 (about 1600 shares) in January at HK$131 and bought 939. At same time I also sold all my MTR, East Asia Bank stocks (small qtys only) but they have performed very very well lately. The recent height of 005 is only HK$133.xx since then.
I have 005 n believe it's ready to climb-up now, but you can earn interest whenever you buy. And no worry if it drop-down.
But if I have spare $$, will buy others i.e. 3328, 939 etc.
With the inclusion of several large China banks in the HK stock market in latter half of the year and 939 finally enter HSI as Blue chips, stockholders are split with choices of investment in the Banking category. Though HKSBC is expected to have good prospects and continue growth in near future, I believe its attraction and influence in HSI may not be as high as before.
