Here's something to bowl you over: want an exposure to 80,000 SAPI shares. If you just buy the shares the brokerage would be R10,736, if you buy SSF's the brokerage would be R11,040 and if you prefer CFDs the brokerage would be just R50. Something just does not look right.
Actually the CFD "brokerage" is included in the cost paid for the stock at a rate of .35 of a percent - but because it is capitalised to the initial cost there is no VAT. Add this to your R50 (+VAT?) brokerage. And if you sell you CFD's the same rate again. If you sell of the same day the sell rate drops to .2 of a percent. BUT get Standard OST to give you the low down.
Ja, your calculations are wrong somewhere. You should have roughly 1.6% on the buy for shares, around 0.6% for SSF's (if memory serves) and 0.35% for CFD's. But don't forget your holding costs. A CFD (AND SSF) will cost you annual JBAR + 1 compounded daily on your total exposure. There will almost certainly be a breakeven point where shares become cheaper, the longer you hold
If you trade CFD's in quality stocks with a good dividend yield (and allow for margin variation,) you have the opprtunity to borrow money to buy top quality assets at not much above prime. (They do not have the same tax problems as instalments etc with expiry and rollover.) AND you can have the interest cost against the profit (hopefully) for income tax. So carry them for years if you like - just make sure you have a PLAN. IMO
