Whats a put

gpt
Welcome to WSB.  
  
 A put is an option contract where you pay a small premium to the seller to have the 'option' to short sell a stock at a certain price on a certain date. Essentially we bet that Facebook's stock would fall far, so we made about 1500% profit off of this trade. 
  
 Unfortunately for me, I only made 1500% off of $200, unlike OP who bet like $50k
