Book excerpt: Now more than ever, people are being affected by the fluctuations in the global economy and by financial uncertainty - with major impacts on their savings, portfolios and pensions. Fully updated for this fourth edition, How the Stock Market Works tells investors what is being traded and how, who does what with whom, and how to evaluate a particular share or bond in light of rival claims from critics and admirers. From the practical consequences of being a shareholder to a basic coverage of the taxation regime, the book provides a wealth of information on individual product types as well as the key players themselves.
