第七步：计算盈亏

这个理论的前提是希望每个月赚5%盈利。所以我们必须学会计算每次交易所需的Transaction Cost:

Transaction Cost = Brokerage Fee + Clearing Fee + Stamp Duty

Brokerage Fee = Investment Amount * Brokerage Rate      (Min RM8 - RM28)

Brokerage Rate : 0.1% ~ 0.6% depending on your broker

Clearing Fee = 0.03%

Stamp Duty = RM 1.00 per RM 1000.00 per transacted

*1 lot = 100 units


Example:

Assume that you are using Maybank (brokerage rate 0.42%), you want to buy for Stock  A at RM 1.00 for 100 lots. Your transaction cost will be :

Investment Amount : RM1.00 * 100 * 100 unit = RM10,000.00

Brokerage Fee = RM 10,000 * 0.42% = RM42

Clearing Fee = RM 10,000 * 0.03% = RM3

Stamp Duty = RM 10,000/1000 = RM 10

So that your transaction cost = RM42 + RM3 + RM10 = RM55

Your Investment Cost = RM10,000.00 + RM55.00 = RM10,055.00


Now you want to sell Stock A at RM1.07 for 100 lots. Your transaction cost will be :


Investment Amount : RM1.07 * 100 * 100 unit = RM10,700.00

Brokerage Fee = RM 10,700 * 0.42% = RM44.94

Clearing Fee = RM 10,700 * 0.03% = RM3.21

Stamp Duty = RM 10,700/1000 = RM 11

So that your transaction cost = RM44.94 + RM3.21 + RM11 = RM59.15

Your Investment Sales= RM10,700.00 - RM59.15 = RM10,640.85

Profit/Loss = RM10,640.85 - RM10,055.00 = RM 585.85

Profit = 0.586%
