That's rich in view of the fact you are the one who is expressing aggressive ignorance. The truth is:
1. An ETF tracking a specific passive index is legally obligated to purchase the shares of a new company added to that index with zero discretion allowed no matter how irrational the pricing might be.
2. Contrary to what you've been spewing about ETFs adding the stock gradually over time, the truth is all ETFs make their full purchases BEFORE the company is actually even added.
Doubt it? Do a quick google search: How soon do ETF's tracking a specific index buy the stock in a new company added to the index they track?
So stop being a jerk with your personal attacks - especially when you don't know what you are talking about.
