Introduction to Investments
Definition and Scope of Investments
Investments encompass the allocation of resources, primarily capital, with the expectation of generating future benefits. These benefits can be in the form of income, capital appreciation, or both. The scope of investments includes a broad array of asset classes such as equities, bonds, real estate, commodities, and alternative investments.
Types of Investors
Investors vary widely in their objectives, risk tolerance, and investment horizons. The main categories include:
- Individual investors
- Institutional investors (pension funds, mutual funds, insurance companies)
- Hedge funds and private equity firms
Understanding investor types helps tailor investment strategies to specific needs and constraints.
Financial Markets and Instruments
Overview of Financial Markets
Financial markets facilitate the buying and selling of financial assets. They are classified into:
- Primary markets — where new securities are issued
- Secondary markets — where existing securities are traded
Market efficiency and liquidity are crucial factors influencing investment decisions.
Major Financial Instruments
Investments involve various instruments, including:
- Equities (stocks)
- Debt securities (bonds)
- Derivatives (options, futures)
- Alternative investments (real estate, commodities)
Each instrument has unique risk-return profiles and strategic uses.
Investment Strategies and Portfolio Management
Investment Strategies
Investors adopt different strategies based on their objectives:
- Passive Investing — index funds, buy-and-hold approach
- Active Investing — stock picking, market timing
- Strategic Asset Allocation — long-term target allocations
- Tactical Asset Allocation — short-term adjustments based on market outlook
Portfolio Diversification
Diversification reduces unsystematic risk by spreading investments across various assets, sectors, and geographies. The core idea is:
- Not putting all eggs in one basket
- Combining assets with low correlation
Proper diversification enhances risk-adjusted returns.
Risk and Return
Understanding Risk
Risk refers to the uncertainty surrounding investment returns. Types of risk include:
- Systematic risk — market-wide factors, non-diversifiable
- Unsystematic risk — asset-specific factors, diversifiable
The Capital Asset Pricing Model (CAPM) emphasizes systematic risk.
Return Measures
Key metrics to evaluate investment performance include:
- Expected return
- Historical return
- Risk-adjusted return — Sharpe ratio, Treynor ratio
Valuation of Securities
Fundamental Analysis
This approach involves analyzing financial statements, economic indicators, and industry conditions to estimate intrinsic value.
Technical Analysis
Focuses on historical price and volume data to forecast future price movements. Tools include:
- Charts and patterns
- Indicators like moving averages and RSI
Valuation Models
Common models include:
- Dividend Discount Model (DDM)
- Price/Earnings (P/E) ratio
- Net Asset Value (NAV)
Efficient Market Hypothesis (EMH)
Forms of EMH
The hypothesis suggests that:
- Weak form — prices reflect all past market data
- Semi-strong form — prices reflect all publicly available information
- Strong form — prices reflect all information, public and private
Implications for Investors
If markets are efficient, beating the market consistently is challenging. It supports the case for passive investing and index funds.
Behavioral Finance
Psychological Biases
Behavioral finance studies how cognitive biases affect investor decisions:
- Overconfidence
- Herd behavior
- Loss aversion
- Anchoring
Impact on Markets
Biases can lead to mispricings and market anomalies, providing opportunities for active investors to exploit.

- Financial Industry Regulatory Authority (FINRA) rules
