Calculate best ETF returns, ETF return stability, and other statistics among ETFs; first I'm doing this manually but later I will systematize this and calculate the same numbers for all the different ETFs I might be able to invest in. I'm starting with QQQ.csv
ETF statistics Example command:
GOOGLEFINANCE - Google Docs Editors Help GOOGLEFINANCE("NASDAQ:GOOG","price", DATE(2014,1,1), DATE(2014,12,31),"DAILY")
Date Price (Closing)
Date Close if we're want historical data for all the ETFs on some big list we compile from Morningstar or Google or wherever, we can use Sheets' functions to "for-each" through all of em and put all the data in Sheets properly
