As beginner, I could just meet the requirement:
HSBC put warrant 9513 buy 0.192 (2008/10/23), sell 0.265 (2008/10/24) earning 38%.
Many thanks for your valuable teaching and guidance.
Will try my best to obtain better result.
I have sold 2/3 of my stock during HSI 26,000. (Rebound from 23,000)
I saw many friend & relative still kept or brought stock when the market is going down. The feel so sad.
If I same as them & kept the stock till now. I think I will died. C-Fu, thanks, you save my life. Even I am not a good student. (Not always hold bear overnight) But as least I can earn some profit or minimize loss.
