### Comment:
The price swings are massive in terms of dollar exposure to fairly normal moves in the market. Look at if you had bought 2930Cs today about 2 hours before close - they were trading at $2 and closed at over $9 because SPX went up about 10 points 
  
 Edit: plus cash settlement means spreads are easier to handle + tax treatment + you only need a couple contracts to get a lot of dollar exposure. No more trading 100 SPY contracts

### REPLY:
So a 10 point move in the ES can cause a SPY or SPX contract to increase 4x? That’s what I’m looking for.
