How to calculate CAGR and Volatility from ETFs and indexes

[Arturo]

Hi all,

i would like to find variables like CAGR and Volatility from 4 or 5 ETFs here in Europe. The issue is that some of them started very late, like in 2005 and 2008 or after. All of them are following an index. I know that ETFs don't replicate exactly the index, but are very close. My question is:

if you calculate the CAGR and Standar Deviation from the index, can we confirm that would be the same for the ETFs that follow the same index?

thanks in advance
