Top 10 FTSE, DAX, S&P

Anyone know where I can get a list of the top 10 companies on the Ftse100, Dax30, S&P500? What I mean by the top ten is the free float weighting (incl. market cap) i.e. the stocks that have the most influence on the Index. I realise I could probably work this out myself, except for the S&P (500??), but was hoping someone would know of a web site/page that might list these and have them up to date. Thanks in advance

p.s. I realise I could go on volume and market cap alone, but I'm after the actual free float weighting in correct order.

If you want to start trading and looking for latest stock market quotes I find digitallook as very good and easy to use.

Traderpedia's always good

I believe use Google finance is a good start, they provide some tools...
