I think we have a misunderstanding. When you sell to open a put position you can allow the put to expire worthless as long as the underlying stays above your put price. Where I come from "cover" means closing a short trade - do you mean "exercising" the put completely?
If May 150 puts are $2...
Or if the put is stupidly expensive as they can be and the iv off the chart; often prior to earnings. For this to work you are approaching shorting puts as a trader which seems is not a popular background for many of those who post here.
My math is based on the minimum CBOE 20% - my broker is 25%. I understand the minimum margin requirements and also understand it can go up exponentially if the underlying sinks.
What risk am I not seeing. That the underlying may go to zero on a black swan event and I could lose everything...

Well if I wanted to short 50 May 130 puts on MA ~ .30 and the underlying at 171 I'd need min $66,500 for a max profit of $1,500.
If I wanted to short 50 May 150 puts on MA ~ 2.00 and the underlying at 171 I'd need min $85,000 for a max...
Clearly a lot of cash is required to short puts. Even in the example of YHOO, if you were shorting the May 14 puts at .45 ~ it looks like you would need $40,000 in your account to short 100 contracts.
14*100*100*.25 (25 % approx margin percentage requirement)=35,000
plus cost of the option...
At the current price of .44 for the May 14 put ~ the margin requirement for shorting 10 puts would be $3510.
And they do not use cash collected towards the requirement.
Thanks itembonds and others; just covering my math. Appreciate your indulgence and cautions - absolutely agree this naked puts not for everyone. But if no one every came to America because of risk then this country would become the power it is.
I understand the risk far too well. But I also see the potential if managed properly. I'm interested in the meat and potatoes of fees associated with shorting a put which is why I chose that example of selling YHOO 14 puts.
I thought it would be a simple example where someone could say...
thanks itembonds, so not many brokers let you do naked puts for low margin on the underlying I am sensing. For some reason the figure 20% was in my head...thanks again
"Trust me writing puts is not as easy as it seems on text or in a book. And many times, the unthinkable will happen to you...
my post was based on this article:
http://www.schaefferresearch.com/commentary/content/options+101+put+selling+ahead+of+earnings/observations.aspx?id=92525
The article left out how much margin the individual would need in his account to make such a trade.
That is why I posted here. So...
First off, great site - been lurking for a while.
I have a question please and hope it is easy to answer.
If I shorted 500 contracts of YHOO May 14 put at $1 that would be an purchase of $50,000.
I get that.
I understand the CBOE has margin requirements for options etc - but...
