## Stocks: Definition and Classification in Economics
**Definition:**
A stock, also known as a share or equity, represents a unit of ownership in a publicly traded corporation. It is a financial instrument that entitles the holder to a proportional share of the company’s profits, assets, and voting rights. Stocks are issued by companies to raise capital from investors.
**Classification in Economics:**
Stocks are typically classified into two main categories based on their characteristics and risk profiles:
1. **Common Stocks:**
– Represent ownership interest in a company.
– Holders have voting rights and entitlement to dividends (if declared).
– Typically carry higher risk than preferred stocks.
2. **Preferred Stocks:**
– Represent a hybrid between stocks and bonds.
– Holders have priority over common stockholders in receiving dividends and repayment of capital in the event of liquidation.
– Typically carry lower risk than common stocks.
**Types of Stocks:**
Within the two main categories, stocks can be further classified into various types based on their purpose, industry, or other specific characteristics:
**Common Stocks:**
– **Growth Stocks:** Stocks of companies with high growth potential but may not be currently profitable.
– **Value Stocks:** Stocks of companies that are currently undervalued based on their financial metrics.
– **Income Stocks:** Stocks of companies that pay regular dividends to investors.
– **Speculative Stocks:** Stocks of companies with high volatility and uncertainty.
**Preferred Stocks:**
– **Cumulative Preferred Stocks:** Dividends that are not paid in a particular year accumulate and must be paid in the future before dividends can be paid to common stockholders.
– **Non-Cumulative Preferred Stocks:** Dividends that are not paid in a particular year are lost and not carried forward.
– **Convertible Preferred Stocks:** Can be converted into a specified number of common shares at the holder’s option.
– **Participating Preferred Stocks:** Entitles holders to participate in any additional dividends paid to common stockholders.
**Importance of Stocks in Economics:**
Stocks play a crucial role in the economic system by:

**Stock Returns:**
Investors who hold stocks can earn returns in two main ways:
– **Dividends:** Regular payments made by companies to stockholders.
