Making my spare cash work for this month - ITM CC

I initiated an ITM covered call for ISRG today.

The shares has been falling for the last 3 months. It looks like it found support today. Looking at the weekly chart, it is a support level in 2007.

I am not optimistic about the market but I believe it will not fall like a stone before the end of the year.

So I initiated an ITM covered call

Buy shares at 253.55
STO Dec 250 SC at 9.5
Cost = 244.05

This will give me 2.35% return for the month. Not bad for a short term and relatively safe trade. I believe this is better than just leaving the cash idle. I have good safety net for 2.35% return or ROI annual 28.13%. Not too shabby.

Primary Exit : Let the shares be called out
SE: If shares fall below 249, add a protective put to collar the trade and manage it longer term.
