It's always good to understand the underlying calculations and theory. However, we tend to make things too complicated and my layman's way of looking at it is as follows: 1. you buy an SSF at a share price of R100-00, ie the underlying price. 2. It actually "costs" you the SSF price (which takes account of interest etc for the company providing the SSF). Say the SSF price is R101-40. 3. You decide you want to make R2-00 profit. You therefore need to sell it at an SSF price of R103-40. 4. You then need to check what the underlying price would be to achieve an SSF price of R103-40. Say this is R103-90. 5. You then put in your sell order at an underlying price of R103-90. So, to make a R2-00 profit, you effectively buy at R100 and sell at R103-90. This example ignores the brokerage costs of R68-40 (paid twice, ie when buying and when selling, so you need to factor that into your desired profit, which will also be affected by how many contracts you buy, ie the R68-40 is fixed per transaction, so the more contracts you buy the more irrelevant the fees become). 6. You need to be aware that the SSF price changes from time to time, so to achieve your R2-00 profit you may need to change your selling price of R103-90. So, what one needs to appreciate, as per the example above, is that the share price must generally go up a lot more than the amount of profit you are targeting. Trust this simplistic explanation helps!
