### Comment:
Pretty sure that SPY has something like 260 billion in assets and its market cap is around 240 billion 
  
 If the two values get too far apart, there's an authorized participant for the ETF that buys/sells shares as needed to keep it in line

### REPLY:
Okay so I’m guessing the disparity lies between the amount of spy traded vs total assets in sp500. Still don’t understand how derivatives are used to inflate value tho.
