I am starting out in share investing and I am going to apply a Buffet-style approach to valuing shares and purchasing in a selective, contrairian manner. I intend to set up my own valuation program (in excel) using company historical data.
However, as I understand it, one needs at least 5 - 10 years worth of historical financial data on a company before attempting to predict future returns on equity (ROE), P/E ratios and the like.
I was wondering if anyone new where I could obtain this info for ASX companies without having to subscribe to valuation programs like StockVal or trawl through a decades worth of annual reports.
PS: I couldn't find this specific topic with a forum search, but my apologies if this topic has been raised numerous time previosuly.
