Comprehensive Encyclopedia Article on Stocks, Covering Historical Context, Types, Key Events, Explanations, Mathematical Models, Importance, Applicability, Examples, and More

Historical Context

The concept of stocks can be traced back to ancient Rome, where trading of “partes” (shares) in public corporations first took place. However, the modern stock market as we know it began in the early 17th century with the formation of the Dutch East India Company, the first to issue tradable shares to the public.

Types of Stocks

Common Stock

  • Represents ownership in a company and a claim on part of the company’s profits.
  • Typically includes voting rights on major corporate decisions.

Preferred Stock

  • Also represents ownership but usually does not come with voting rights.
  • Dividends are paid out to preferred shareholders before common shareholders.

Class A & Class B Shares

  • Companies can issue multiple classes of stock with different voting rights, often denoted as Class A and Class B shares.

Detailed Explanations

How Stocks Work

Stocks are issued by companies to raise capital for growth, investments, or other financial strategies. Investors purchase stocks with the expectation of earning a return through dividends and/or capital appreciation.

Mathematical Models

Dividend Discount Model (DDM)

$$ P_0 = \frac{D_1}{r - g} $$
where:

  • \( P_0 \) = current stock price
  • \( D_1 \) = expected dividend in one year
  • \( r \) = required rate of return
  • \( g \) = growth rate of dividends
