What is a Portfolio?

A portfolio is a collection of financial investments held by an individual or institution. It's the sum of all your investment holdings working together toward your financial objectives.

The Pie Analogy

Think of your portfolio like a pie:

• Each slice represents a different investment
• The size of each slice shows how much you own
• The whole pie represents your total investment value
• You decide how to slice it based on your goals

Components of a Portfolio

Stocks

Ownership in companies, offering growth potential.

Bonds

Fixed-income investments providing steady returns.

ETFs

Funds trading like stocks, offering diversification.

Mutual Funds

Professionally managed pools of investments.

Cash

Portfolio Allocation

How you divide your portfolio among asset types depends on:

Risk Tolerance

• Conservative: More bonds, less stocks
• Moderate: Balanced mix
• Aggressive: More stocks, less bonds

Time Horizon

• Short-term (< 5 years): More conservative
• Medium-term (5-10 years): Moderate allocation
• Long-term (10+ years): Can be more aggressive

Goals

• Retirement: Growth-focused initially, then income
• House down payment: Conservative, shorter-term
• Wealth building: Growth-oriented

Common Portfolio Strategies

All-Weather Portfolio

Balanced for any economic environment using multiple asset classes.

Portfolio Management
