Sorry for the confusion. I'm going to create a hypothetical scenario to make it more clear:
Let's say I don't own any TSLA stock but have $125K in savings.
I am going to buy a house in two weeks. The down payment needed is $100k. I have the $125k in cash now, but would like to leverage it more effectively. I place it in my brokerage account which has a 40% margin requirement for TSLA. I then leverage the full margin and purchase 400 shares of TSLA at $650 for a total of $260k, using $104k of my cash as leverage. I then sell 4x June 23 covered calls at a 750 strike for a premium of $23,000 per contract, and therefore have $92K in premiums plus my remaining $21k in cash. I withdraw $100k in cash for my downpayment and am left with $13k in cash in my account and still hold 400 shares of TSLA under contract, which if and when called away in two years will give me a return of $40k. If my brokerage is charging say 3% interest on the $156k margin loan, that is a cost of $9360 over two years, and I still net over $30k or $15k per year. If stock price crashes and I get margin called, the shares are liquidated and contracts closed and even if I get liquidated to zero, I have only lost the amount of margin interest paid to date and possibly the $13k that was still in my account. If the stock goes down modestly, and I can source a bit more cash, I can buy the contracts to close and I'm good. Either way, I still have the downpayment for my house and potentially some profit and potentially some $TSLA if I can buy the contracts back. What am I missing here?
