### Comment:
I thought it was just useless. In what way is it a scam?

### REPLY:
It’s only 30 companies and it is price weighted not market cap weighted like SP500, so BA going up 1% has a bigger impact than AAPL because it’s share price is so much higher even if it’s smaller in market cap. 
  
 It made sense when it was created to have a simple calculation but it’s so misleading and inferior in this age of immense computing power.
