This is very interesting...
But the CBOE has allowed this type of covered call treatment since 2015.
See the attached documents.
The press release suggests that something has changed, but it's not clear what.
The regulatory guidance published in 2015 allows brokers to treat short index calls as covered by a long position in an ETF that tracks the same index; it does not require brokers to do so.
Maybe this new policy is intended to push or even force brokers to allow this treatment in most or all retail accounts.
We have been selling $XSP calls as a hedge against SPY for quite some time. Schwab does not treat them as covered calls. For margin purposes, they are treated as naked short calls. This has not been a problem for us. Our account is approved for naked short calls, and we have sufficient equity to support the position.
Our account does not have portfolio margin. We have not had a need for it.
It would be a significant shift if most brokers began to recognize these positions as covered calls in an ordinary retail account that is not approved for naked short calls.
As the memo notes, it's not just SPY and XSP.
We also sell $XND options against QQQM. Those are not recognized as covered, either. And there are many other examples.
