Selling Cash Secured Puts on margin while holding BOXX as collateral
BOXX is basically a fund that shifts STCG -> LTCG for the risk free rate. Behaves kind of similar to a money market, but technically it's an ETF so can't directly use it as collateral for selling CSP's. And need to hold BOXX for at least a year to benefit from LTCG, so assignment on CSP's would cancel out benefits of BOXX. Here is my plan:
Selling CSP's on margin, and either rolling the option near expiration if it's in the money, or liquidating my lots of BOXX that are LTCG a few days before assignment if I'm expecting to be assigned.
Cons I see with this plan:
1.If I get assigned early (uncommon), I sell BOXX and pay off the margin balance the next day, paying interest for just 1 day (minimal).
If i were to over leverage and sell too many contract, I might have a margin call. However, I will be conservative and only open contracts up to the value of the equity in my account. For example if I have $10,000 in my account, I wouldn't open more than 1 options contract with a strike price of greater than $100. Basically I wouldn't take out more margin than the value of the equity in my account. So I consider this a non factor.
BOXX's tax advantage may be reversed by an IRS ruling, but then I'm just in the same position I was in before this strategy, which is paying STCG on the collateral earnings rather than LTCG, not really a con.
For people living in low tax states who benefit from BOXX over traditional money market funds as collateral, what are the other downsides of this strategy, which is essentially switching your collateral for CSP's from money market funds to a more tax advantaged fund? Is there other instances I would need to pay interest on the margin I'm not considering or something?
Never heard of anyone discuss this strategy. Let me know what y'all think.
