It is clear to me there is a general misconception about MSTY from these posts.     

MSTY does not 'merely' sell covered calls to generate yield.     They can enter into credit spreads, and take advantage of pricing opportunities in the market.    

They currently hold the following positions:   
1) $23M short calls on 350-395 strikes on 1/17.   
2) $4M long calls on 460 strikes on 1/17.  
3) 53,000 contract, synthetic long position at 315 strike for 2/21  (equal to delta exposure of 5.3million shares) 4) Almost 2B of cash earning near 5% interest 

They will need to reposition their synthetic long position soon,  which is an excellent time to do so with implied vol so suppressed.    

We should be happy about this for long MSTY.   

The short calls expiring 1/17 are all OTM,  which is great for premium recovery. 

And OTM call 460 strikes allow them to participate in extreme upside movement & is fully funded by the short call.
