My Stock Strategy for Jan to Jun 2010

My current holding is as below:
5 lots of Singtel (CPF)
5 lots of SingTel (Cash)
20 lots of SingPost (Cash)
25 lots of Cambridge (Cash)

My sell plan is as below:
If Singtel reaches $4.00, I will sell 5 lots of SingTel(Cash)
If Singtel reaches $4.20, I will sell 5 lots of SingTel(CPF)
If SingPost reaches $1.15, I will sell 15 lots.
If SingPost reaches $1.25, I will sell 5 lots.
If Cambridge reaches $0.60, I will sell 10 lots.
If Cambridge reaches $0.70, I will sell 15 lots.

My buy plan is as below:
If DBS reaches $12.50, I will buy 1 lot.
If SPH reaches $3.20, I will buy 5 lots.
If SuntecReit reaches $1.10, I will buy 5 lots.

If none of the prices as above are reached, I will keep all stocks for dividends.

Please take note that I am applying my rule No. 1, which is I do not try to predict the market direction. So I have planned for both market directions. I am also applying my rule No.3 which is "It's far better for other to buy an overvalued stock from you, rather than you buy an overvalued stock from other".
