Dividends are typically paid out of the company's profits and can be a great source of regular income for investors. 2. Yield: Yield is a measure of the return on an investment. It is expressed as a percentage and represents the income generated by an investment relative to its cost. Yield can be calculated for different types of investments, such as bonds or stocks, and is an important factor to consider when making investment decisions. 3. P/E Ratio: The price-to-earnings ratio (P/E ratio) is a measure of a company's valuation. It is calculated by dividing the market price of a company's stock by its earnings per share (EPS). The P/E ratio is commonly used by investors to determine whether a stock is overvalued or undervalued. 4. Volatility: Volatility refers to the degree of variation of a security's price over time. It is a measure of the risk associated with an investment and can have a significant impact on investment returns. High volatility can lead to sharp price fluctuations, while low volatility indicates a more stable investment. 5.

By diversifying a portfolio, investors can reduce the overall risk of their investments and potentially improve returns. Understanding these key financial terms can help investors make more informed investment decisions. It is important to continue learning and staying up-to-date with the latest financial developments to navigate the complex world of investing.
