Hello everyone, I have been trying to find the source of Sector data but haven't had a success yet. In my understanding there are Sectors >> Industries >> and individual stocks that make up the industries. Using the Yahoo Finance database I am able to find the industry tickers and tickers for individual stocks, no problem. The problem is that even though they have the brakedown by sectors, they do not have the actual tickers for those sectors. For example, tickers and data for the following sectors... Basic Materials Capital Goods Conglomerates, etc... What I would like to do is to try to analyze sectors historically. Please, if anyone has ever faced this problem, let me know if there is such a thing as historical data by Sector. And I will greatly appreciate if you can give me the source where I can find this information. Also, if anyone has faced this problem, what are some other way to track sector performance thoughout the history using either TradeStation or WealthLab. I will appreciate any relevant information, Jamie.
