What Does “Priced In” Actually Mean? Explaining 50 Investment Terms We Use Without Really Thinking About Them, Including Share-Price Movements

The article explains that “priced in” describes the extent to which a share price reflects expectations ahead of an announcement. The market is said to incorporate not only current facts but also future outlooks and market participants’ forecasts, with buying and selling activity shaping prices.

Rather than presenting 50 terms as a dictionary-style list, the book is structured around how share prices move, explaining both the meaning of each term and how it appears in share-price movements. Terms such as trading volume and PER are discussed not only through their definitions but also by examining why they affect price movements.

The chapters are described as covering the mechanisms by which expectations and catalysts are reflected in share prices, followed by how to assess corporate value and financial results, supply and demand, charts and investor trading behavior, corporate events and the external environment, and finally the movement of funds across the market as a whole. The aim is said to be to help readers develop the ability to consider multiple possibilities rather than making judgments based solely on news or financial results.

As specific examples, the article points out that phenomena such as “the share price falling despite strong financial results” and “the share price rising after a loss forecast is revised upward” result from the gap between expectations and facts. Share prices are formed based on assumptions about the future, and buying and selling may begin before an announcement is made.

The article concludes that the goal is not to memorize 50 terms, but to reach a point where, when looking at news, financial results, charts or supply and demand, readers can think for themselves: “Which term explains this price movement?”
