Something About Business Math

I have heard people talk about Peter Lynch that he was a veteran of the American campaign in Korea, a graduate of Wharton Business School, a Wall Street tycoon who bloated a small mutual fund into a mega fund called Fidelity Magellan or something quite to that effect. So, when I came across a book titled "One Up On Wall Street" written by Mr. Lynch himself in a discount bookstore, I just couldn't afford to pass it up. I had to buy it. The book was priced at C$19.90 and I bought it for C$ 1.90. Considering the wealth of knowledge I have gained from the book, I realized that I bought the book at a value much less than its intrinsic value. The book is an interesting read replete with Lynch-humor. It convincingly makes the case that even a guy with no Wall Street DNA can make money in the market. This book successfully demystifies the process of investment analysis. I recommend anyone reading it. Not quite sure if it is still in print, though.
Anyone managing one's own investment ought to be able to beat the benchmark index. If not, the wise ones advise to leave it to the pros. But then, pros are also not infallible.
You don't need to be an MBA to be able to analyze business financial reports it seems. These financial reports and balance sheets are constructed with certain logic behind them. Understanding the dynamic relationships among the numbers used in the reports is an important part of company analysis. When it comes to math skill needed for the job, Mr. Lynch says that knowledge of high school math is all one needs.
