The idea for a walk along Wall Street
Wall Street is the financial centre of New York. That is where the financial markets move. Although people make forecast analyses, the ups and downs of the performance of the stock market are unpredictable. This is why Malkiel uses the metaphor of a walk. The concept of a walk through the stock market was introduced by academics to describe the instability that characterises its trends, as opposed to the professionals, however, for whom it is possible to make predictions on the future trends of the market using charts and analysis. Hence, Malkiel becomes a guide and takes readers on an explanatory tour of the complex world of finance.
