有危就有機~ 睇黎係定律~
yes, but remember, we can't always win@@'
even warren buffett has made some mistakes in his life too~~
And...one point is very important here, that is, "the risk inside"
it's meaningless to have a return of 30% with the risk of "lossing all your money at the same time, like 賭大小,一鋪清袋== "
that's why we mention the risk, (i.e. standard deviation of return, the alpha, diversification of the portfolio to elimilate the systematic risk, and even the concept of "stop loss") these factors is more important for us and deserves our full attention.
>>>>>>To conclude, when the guy just mention return, making it as a selling point to you is just "foolish" guy, the market now have more concerns with risk, becare, man.
