油價低下來，利息率會低下來，股市自然生高，這倒是真的, 但你買時的價格是不是已經reflected this new

information? 

With new technology, the market is getting more and more efficient. 
Any new public information can be incporated into stock price instantaneously. 
You think you acted quickly, but it is already too late.

It is hard to beat the market with public available information.

 

在低點買進，buy and hold 就好了，

幹嘛一驚一乍的 ：）

 

莫非你們在day trading?
