I bought the book with high hopes of being able to perform analysis. I am reasonably proficient at Excel. What I do not know is how to use statistical analysis for analysing stock trades. I was disappointed. After skimming though the book, I found that it was just too concise for the subject. Serious statistical analysis of stock trades would require much more indepth workflows, descriptions and examples. The book offers little value there. The price does not match the value.
