Manage Concentration Risk

Concentration risk comes from holding too much in one company, sector or geography, so a single event can do severe damage. Diversification spreads that exposure so no one event devastates the whole portfolio.

In this lesson

Manage Concentration Risk is part of Building Wealth Across Life Stages. This preview shows how wealth-building connects to everyday family decisions such as earning, saving, spending choices, goals, approvals, or parent-guided money conversations inside Progress Penguin.

Think about this money choice

Dayo has invested nearly everything into one company because it has performed well for five years.

How it works

Concentration risk in an investment portfolio is the risk that arises when too much is held in a single company, sector, or geography. If that single position fails or falls sharply, there is no offsetting gain elsewhere to cushion the loss. Diversification across multiple assets, sectors, and geographies reduces this risk — because events that damage one holding rarely damage all holdings simultaneously.

Apply it to a real decision

Real-life money moment: Dayo has invested nearly everything in a single local telecommunications company because it has performed well for five years. The company announces it is losing a key government contract and its share price falls 55% in one week. Dayo's portfolio falls by a similar proportion. A portfolio spread across ten companies in five sectors might have fallen 10% — the telecom holding would have been a painful component, not the whole story.

Managing concentration risk means:

Only managing concentration risk once your portfolio exceeds 5000000 in local currency in total value

Spreading investments equally across 100 different assets regardless of their quality

Reducing over-reliance on any single asset, company, or sector in your portfolio

Concentrating investments in your best-performing asset since that maximises total return

You hold 70% of your portfolio in one company's shares. The company announces poor results. Your loss:

Is limited to 30% since your other holdings are protected from this company's results

Is significant since 70% of your total wealth is tied to one company's performance

Is zero since stock losses only materialise when you actually sell the shares

Is minimal since one company's poor performance rarely affects the overall market
