Diversification (why it’s your superpower)

Estimated time: ~2–4 minutes.

TL;DR

• Diversification means one mistake doesn’t ruin you.
• Broad ETFs reduce company-specific risk (fraud, scandals, bad CEOs).
• Your goal is a portfolio that is hard to break, not one that is “perfect”.

The two kinds of risk

• Company-specific risk: one stock can go to zero.
• Market risk: whole markets can drop (even diversified ETFs can fall).

A simple mental model

If you own 1–5 stocks, your result is heavily driven by a few stories. If you own a broad global ETF, your result is driven by the world economy over time.

Common beginner mistake

Buying many ETFs that are actually the same thing (overlapping holdings), thinking it’s diversified.
