March 7 , I am going to open a new position on Berkshire. I do my usual open interest analysis to see where sellers and buyers put their trades.
Open Interest
Strong OTM Calls @210 (resistance point ) . Scarce support point (OTM Puts). What I don’t like is a synthetic short stock position @200 (bearish sign). Anyway I will try to open my position under 1STD.
Max Pain @200.
Conclusion: BRK-B , sold 1 Cash Secured Put , strike 192.5@0.65 , expiry March 15. Weekly return 0,33% AROI 15,4%
