Investing Part Six: Stocks vs Bonds

Overview

  • Focus on two basic building blocks of investing: stocks (equity) and bonds (fixed income).
  • Importance of understanding risk in investing.

Two Fundamental Investment Options

  1. Ownership (Equity)

    • Example: Coffee shop owner offers an investment opportunity.
    • Investor can own 50% of the business for $100,000.
    • Terms:
      • Shares can be divided into different amounts.
      • Owning part of the company is referred to as equity.
      • Interchangeable terms: shares, shares of stock, stock.
  2. Lending (Debt)

    • Coffee shop owner offers a loan option.
    • Investor lends $100,000 for 10 years at a 4% interest rate.
    • Terms:
      • Fixed income means receiving regular interest payments until the loan is paid back.
      • Common terms: bonds, fixed income.

Risk Analysis

  • Higher Returns vs Higher Risk
    • The potential for higher returns generally comes with increased risk.
  • Scenario Analysis:
    • Best Case:
      • Coffee shop becomes a successful franchise (e.g. Starbucks) worth $10 billion.
      • Investor with equity would have stake worth $5 billion.
    • Worst Case:
      • Business goes bankrupt; equity investment becomes worthless.
      • Debt investment returns only partial amount.
  • Matrix for Analysis:
    • Ownership (Equity) vs Lending (Debt):
      • Best case for ownership: $5 billion.
      • Worst case for ownership: $0.
      • Best case for lending: $140,000 (interest + principal).
      • Worst case for lending: $78,000 (interest + partial repayment).

Moderate Scenarios

  • Moderately Successful:
    • Business valued at $1 million after 10 years.
    • Equity stake worth $500,000; bond investment returns $140,000.
  • Moderately Unsuccessful:
    • Business valuation drops to $100,000.
    • Equity stake worth $50,000; bond investment still returns $100,000.

Key Takeaways

  • Stocks (equities) generally riskier with high upside potential.
  • Bonds (debt, fixed income) have limited upside but are more stable and less risky.
  • Practical examples of risk and return should be understood for informed investing decisions.
