主题：忘却牛熊之争，迎接股市挑战 -- 倥偬飞人

Any portfoilo could have a pop up from time to time. The challenge is to do it consistently - i think the most challenge is you have to take 10% cash out every month.

This is a also a great test on your investment principles: will they perform in any market circumstances? In a bull market, it will be relatively easier; what if the market takes a sharp turn to the downside? Will you be wiped out overnight?
