Common Stocks and Unusual Profits. Philip A. Fisher.
If you are interested in the stock market, it is best to start learning it with theory, and the best book on the stock market is the work of Philip Fisher.

Common Stocks and Extraordinary Returns is a book that will not only teach you the theoretical foundations of stock trading but also reveal some practical secrets of this activity.
Its author is not just a theoretical analyst, but the former owner and manager of a large inversion fund with billions in turnover.
Philip Fisher was one of the first to use unconventional approaches to stock valuation; he determined the actual value of an asset rather than relying on a biased market indicator.
The book's main sections are:
1. Common Stocks and Extraordinary Returns – this section contains the basics that will help you choose the most suitable investment. The key points in this section include what to choose, when to buy, and when to sell.
3. Towards a Philosophy of Investing – philosophical aspects are considered as they apply to stock trading.
A separate chapter in the appendix discusses factors that, by studying, an investor can improve their efficiency in the stock market.
