Quick Reference

Diversification

The strategy of spreading investments across different asset classes, industries, and geographies to reduce overall portfolio risk. Diversification works because different assets often move independently of each other.

Price-to-Earnings (P/E) Ratio

A valuation metric calculated by dividing a company's current stock price by its earnings per share. It indicates how much investors are willing to pay per dollar of earnings and is used to assess whether a stock is overvalued or undervalued relative to peers.

Compound Returns

The process by which investment gains generate their own gains over time. When dividends and capital appreciation are reinvested, the total investment grows exponentially rather than linearly, making time in the market a powerful wealth-building factor.

Dollar-Cost Averaging

An investment strategy in which a fixed dollar amount is invested at regular intervals regardless of market conditions. This approach reduces the impact of volatility by purchasing more shares when prices are low and fewer shares when prices are high.

Market Capitalization

The total market value of a company's outstanding shares, calculated by multiplying the share price by the total number of shares. It is used to classify companies as large-cap, mid-cap, or small-cap and reflects the market's assessment of a company's total value.

Index Fund Investing

A passive investment strategy that involves buying a fund designed to track the performance of a market index such as the S&P 500. Index funds offer broad diversification, low fees, and have historically outperformed the majority of actively managed funds over long periods.

Risk-Return Tradeoff

The fundamental investment principle that higher potential returns are associated with higher levels of risk. Investors must balance their desire for growth with their ability and willingness to tolerate volatility and potential losses.

Fundamental Analysis

A method of evaluating a security by analyzing the financial statements, management quality, competitive position, and economic conditions of the underlying company to determine its intrinsic value and whether the stock is fairly priced.

Asset Allocation

The process of dividing an investment portfolio among different asset categories such as stocks, bonds, and cash. The optimal allocation depends on the investor's time horizon, risk tolerance, and financial goals, and is considered the most important determinant of long-term portfolio performance.

Dividend Investing

A strategy focused on buying stocks of companies that regularly distribute a portion of their profits to shareholders as dividends. Dividend stocks provide a stream of income and tend to be more established, stable companies, making them attractive for income-oriented and conservative investors.
