Thanks toowit.

It seems you are saying that TCM margin requirement is only 20%. My broker requires 30%, I was wrong when I used 50%.

>>"If stock goes to $7.00 and put cover cost $6.50:
Maintenance Margin: $3160"

I presume this says that if the stock falls to $7, the option premium will be ~$6.50. Margin required would be $6.50 + 20% of $7 = $7.90 * 400 = $3160. Ah! that's just what you said it would be. Eureka !

Thanks for the clarification, toowit ! The essential point is that no cash outlay is required for this bullish position, only sufficient available margin.

Another Postscript:

If the stock drops to $7 and the stock is put to you, still no cash outlay is required for the margin requirement of the long stock is no greater than for that required for the unexercised put(s). If you have adequate margin for one, you have adequate margin for the other.
