BTW, can anyone tell me the author/book that discussed the strategy of trading "fallen angels"(stocks that have fallen about 90% from their all time high)?
I am not sure if this is what you're looking for. But the name of the book you maybe referring to is entitle: Wisdom on Value Investing - How to Profit on Fallen Angels" written by Gabriel Wisdom. http://www.amazon.com/Wisdom-Value-Investing-Profit-Fallen/dp/0470457309
