中資銀行股 is the best, because they are cheap now, really safe and have big potential to grow in long term. If it rise, sell it for short term gain. If it drop, keep it for long term.
I have 10 hands of 3988 and 13 hands of 939, I will sell some of them when the price is right. But for sure I will keep 5 hands of 3988 and 5 hand of 939 for long term (target is 20 years).
