TMUSI covered call FAQ

What does the TMUSI covered call calculator prefill?

A near-30-delta TMUSI call (and put, for the cash-secured mode) at the bid/ask midpoint from the delayed Cboe chain, plus TMUSI's delayed price and the days to that expiration. Every field stays editable.

How is a TMUSI covered call return calculated?

Premium collected divided by your TMUSI cost basis gives the return if flat; the capital gain up to the strike plus premium gives the return if called. Both are annualized over the days to expiration for comparison.

Is this live data?

The prefill uses delayed (~15 minute) quotes, labeled with their as-of time. Check live quotes at your broker before trading; this page is educational arithmetic, not a recommendation.
