4 shares of Yelp?  ...but why?   
  
 I could see if you got a dividend, and you had some setting on your broker to auto-reinvest the dividend as shares, and you had already sold the shares before the dividend hit, leaving you with only 4 shares...  but Yelp doesn't have a dividend.  So you went out and bought 4 shares?

Sold a covered call that executed. Left me with 4 shares.
