Lesson 2: Key Financial Concepts for Investors

Introduction: The Game You Are Already Playing

Every financial decision—saving, spending, investing—is part of a game.

Winners? They understand 3 key rules:

  1. Risk vs. Reward – Playing it safe can be risky.
  2. Inflation – Silently shrinks your savings.
  3. Time Value of Money – A dollar today is worth more than a dollar tomorrow.

Understand these, and money starts working for you.

Risk vs. Reward: What Playing It Safe Really Costs

Meet Alex and Jordan:

  • Alex avoids all risk. Sticks to savings accounts.
  • Jordan diversifies—stocks, bonds, real estate.

20 years later?

Jordan’s wealth grew far more.

Why? Because avoiding risk = missing growth.

Real risk isn't losing money—it's standing still while others grow.

What Risk Really Means

It's not just “losing money.”

It’s opportunity cost—what you miss by playing it too safe.

  • Higher returns = higher risk
  • Lower risk = limited growth

Smart investors don’t avoid risk. They manage it.

Types of Investment Risk

  • Market Risk: Stocks rise and fall—ride it out.
  • Inflation Risk: Savings that don’t outpace inflation = shrinking value.
  • Liquidity Risk: Some assets are hard to sell fast.

How to Manage Risk

  • Diversify
  • Think long-term
  • Know your comfort zone

Inflation: The Silent Thief

Everything used to cost less. That's inflation.

Prices rise over time → your money buys less.

🛑 Saving alone isn’t enough.

If inflation is 3%, and your savings earn 1%, you're losing purchasing power.

More dollars ≠ More value.

How to Beat Inflation

Invest in assets that outpace it:

  • Stocks: 7–10% long-term returns
  • Real estate: Values + rent grow with inflation
  • Commodities: Hedge against rising prices

🔁 Know the difference:

Nominal return = what's on paper

Real return = what you keep after inflation

Time Value of Money (TVM): Why Now Beats Later

Would you rather get $1,000 today or in 5 years?

Take it now—so it can start growing.

💡 Money today > Money tomorrow.

Example:

  • Invest $1,000 at 7% for 30 years = $7,612
  • Wait 10 years, then invest = only $3,870

Waiting = expensive

Why Businesses Love TVM

  • Get paid ASAP
  • Delay paying others

Because money today can be reinvested.

Simple TVM Formula

FV = PV × (1 + r)^n

FV = Future value

PV = Present value

r = return rate

n = years

Example

You invest $5,000 today at an annual return of 7% for 10 years.

FV = 5,000 × (1 + 0.07)¹⁰

FV = 5,000 × (1.967151)

FV = $9,835.76

💡 So, $5,000 invested today turns into $9,835.76 in 10 years.

That’s the power of time + compounding.

Assignment

  1. If inflation is 3% and your bank pays you 1%, are you gaining or losing money?

    a) Gaining (because my balance is going up).

    b) Losing (because my money’s purchasing power is shrinking).

    c) Breaking even (because 1% is still better than nothing).

  2. Which is riskier over 30 years?

    a) Investing in a diversified stock portfolio.

    b) Keeping all your money in cash.
