If you are looking for HK$200 per trade (like most of us do), you don't need to look at fundamentals or valuations. All u need is to focus on flow and execution (you take profit after 5 spread up and cut loss after 5 spread down). And don't blame yourself if you miss a big rally because day trade seldom make money from trend. However, if you think you have more patience, then look at 1-2 month trade, not one day or two (unless something really big happened). If u are a day trader in one second and then an investor in the next, u will be tortured by mkt. You won't have fun at all because all you experience is the aftermath of self-destruction. Be a happy investor!
