### Comment:
Yeah, but if it tanks below $170 your risk is about $962 per contract. For the record, the stock moved about $23 down since last week.

### REPLY:
Your risk is 100 x $10 - d (with d being the amount you made selling the spread) 
  
 This is one of the safer ways to write contracts for stocks that you don't own, selling naked has literally infinite the amount of downside risk so I'm not sure why ~$950 is worse risk than infinite?
