By Steve Denning – The “real market,” Martin explains, is the world in which factories are built, products are designed and produced, real products and services are bought and sold, revenues are earned, expenses are paid, and real dollars of profit show up on the bottom line. That is the world that executives control–at least to some extent.
The expectations market is the world in which shares in companies are traded between investors–in other words, the stock market. In this market, investors assess the real market activities of a company today and, on the basis of that assessment, form expectations as to how the company is likely to perform in the future. The consensus view of all investors and potential investors as to expectations of future performance shapes the stock price of the company.
