What Is Diversification?

From Fidelity Investments. Watch here or open it on YouTube .

Pause when the video describes spreading exposure. Write down which risk diversification can reduce and which market-wide risk it cannot remove.
Before you begin

What this lesson is really solving.

Risk is not simply ‘could go down.’ It includes volatility, permanent loss, inflation, liquidity, and the chance that your plan fails to reach its goal. Compare investments using the kind of risk taken, the likely holding period, fees, and what role the holding serves.

Why this works

Understand the idea before touching the steps.

Risk capacity is what your plan can withstand; risk tolerance is what your nerves can withstand. Your portfolio must respect both.

Do this

Follow these steps in order.

Take the action in each step; then use the deliverable below to prove the lesson is finished.

  1. 1

    Learn the roles of cash, bonds, and stocks without assuming any asset is risk-free in every context.

  2. 2

    Estimate how a large temporary decline would affect your goal and your willingness to stay invested.

  3. 3

    Match shorter horizons with less exposure to assets that can fall sharply at the wrong time.

  4. 4

    Write what you will do during a market drop before one happens.

Worked example

See the standard in context.

A broad stock index fund may fluctuate sharply but spread company-specific risk across hundreds of holdings. A single speculative stock can fall for company-specific reasons. Cash is stable in dollars but may lose purchasing power. Maya assigns each option a role instead of calling one universally safe or risky.

Quality check

Inspect before you move on.

  • You can name at least three different risks, not only price movement.
  • Expected return is treated as uncertain, not quoted like interest on a bank account.
  • The risk level matches the goal’s time horizon and your ability to stay invested.
Make it real

Your deliverable

A risk statement defining your horizon, acceptable decline, and no-panic rule.

Common mistake

Watch for this

Selecting a portfolio from a best-year return chart without considering the worst years.

You’re ready when

Prove it—don’t just recognize it.

You can explain why the highest expected return is not automatically the best portfolio for a specific goal.
