1 What is Diversification?
Diversification means spreading your money across different investments so that if one fails, you don't lose everything.
2 Why It Matters: A Real Example
Investor A: No Diversification
Put all $10,000 into ONE tech company
Company fails → Lost $10,000 (100%)
Investor B: Diversified
Split $10,000 across 50 different companies
One company fails → Lost $200 (2%)
When you own many companies, one bad apple doesn't spoil the whole bunch. The winners can make up for the losers.
3 Types of Diversification
Across Companies
Own stock in Apple AND Microsoft AND Google, not just one
Across Industries
Own tech stocks AND healthcare AND consumer goods—they don't all fall together
Across Countries
US stocks AND European AND Asian—when one region struggles, others might thrive
Across Asset Types
Stocks AND bonds AND real estate—different assets react differently to economic changes
4 The Easy Way: Index Funds & ETFs
Good news! You don't need to buy 100 different stocks yourself. Index funds and ETFs do the diversification for you.
Example: S&P 500 Index Fund
Buy ONE fund and instantly own tiny pieces of the 500 largest US companies—Apple, Microsoft, Amazon, Google, and 496 more. Instant diversification!
We'll cover ETFs in detail in the next lesson.
! What Diversification Does NOT Do
Diversification reduces risk, but it doesn't eliminate it. When the entire market crashes (like 2008), most stocks drop together.
- Does: Protect against one company failing
- Does: Smooth out your returns over time
- Doesn't: Protect against a total market crash
- Doesn't: Guarantee you'll make money
