@OptionsDelta：
1 $Alcoa(AA)$ reasons for the rise similar to Macy's acquisition drive department store sector. I have been watching the trend of the metal sector since Nippon Steel announced its acquisition of $U.S. Steel(X)$ , and then I waited for this big 8000 lot CALL option order $AA 20240216 40.0 CALL$ . But as a rule of thumb, a large call order is 50-50, so I'd still go with the sell put: $AA 20240119 33.0 PUT$ 2 $Marathon Digital Holdings Inc(MARA)$ The bears have finally struck, 20,000 lots of big PUT orders
