Hi GAT,
I agree, the title was a bit click-baity. I was afraid that I wouldn't get any responses, what with christmas eve coming up and all. I have to say that I don't really understand your response, but I'll re-read it a few times.
Let me give the example in broad strokes. I'll do the more detailed calculations after my christmas shopping.
Amount Dividend Yield Cost
100k 2.28k 0
400k 9.12 5.92
Total 2.28+9.12-5.92 = 5.48
Please note that I didn't use the full 6.6 portfolio margin, because there is margin needed for the YM.
Please correct me when wrong.
