How would you define the term "closing price"? One of the most common definitions for the closing price is "the price of the last transaction for a security in a trading session". But nor everyone agrees. Consult any financial dictionary, search the Net and you will find a multitude of definitions. In fact, the definition of a security closing price can differ from one market to another; ranging from simply the last transaction for the day to a price derived from a complicated calculation. It may also vary within a market where one rule applies to one trading segment and another to another segment. The Closing Prices Handbook gets to the bottom of the ambiguity of closing prices and provides detailed definitions of the closing and other key prices disseminated by the global equity exchanges covering 112 countries. Exchange Data's Closing Prices Handbook is a unique reference source for Portfolio Accountants, Portfolio and Hedge Fund MAnagers, Operations Directors and any other professionals working with closing pricing data.
