why $28

gpt
I will have to pull up the options chain again, but I saw good amounts of volume and open interest on strike $28 on some of the dates of expiration and that is where the bigger drop off of prices with options started to fall, if that makes sense.. 
  
 I think marketmakers have setup things so that it could drop down to $28 if needed for whatever reason.. etc. 
  
 Just a 'feeling'
