Do you know where I can find a service that would list all the ETFs and Indexes that a particular stock belong to? For example, I would like to find out all ETFs that has AAPL as one of its components...
Because you want to see correlations? If so, this is a decent site. You might need to be a member now. http://www.market-topology.com/index.php?option=com_impactopia&view=friend&Itemid=2
Nice site Uptik2000 Yahoo now lists stock as a component of which index or ETF http://finance.yahoo.com/q/ct?s=AAPL+Components
Who cares. AAPL makes up 20% of QQQ (4% of SPY). Yes AAPL influences QQQ but it they both still move independently of one another. Just look at both their charts. Anything less than the market cap of AAPL, which is all stocks, has an insignificant effect to any index it is a part of.
Are you looking fr the index that moves along with AAPL - the answer is none. You may go into NASDAQ sector indexes, yet, even NASDAQ OMX does not list their components
