Diversify Across Assets

Explain what concentration risk is and describe how holding too much of one asset or sector creates vulnerability to a single event that diversification across multiple assets reduces.

In this lesson

Diversify Across Assets is part of Starting a Long-Term Investment Plan. This preview shows how long-term-portfolio 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 puts all his savings into one company's shares because he believes strongly in it. His adviser warns against this.

How it works

Concentration risk is the risk that comes from having too much money in a single investment — one company, one sector, or one geography. If that single investment fails, the loss is not offset by gains elsewhere. Diversification — spreading investments across multiple assets that do not move together — reduces concentration risk without reducing the expected return of the overall portfolio.

Apply it to a real decision

Real-life money moment: Dayo puts all his savings into shares of one company because it has performed well for five years. In year six, the company faces a regulatory investigation and its share price falls 70%. Dayo's portfolio falls 70%. A diversified portfolio — holding 20 companies across five sectors — might have fallen 15% if one company collapsed. The diversified portfolio is not immune to loss, but no single event can destroy it.

Open Requests and make a deposit request into savings so you can see how saving starts. Parent approval can happen later.

Quiz preview

Diversifying across assets means:

Putting all money in the single best-performing asset to maximise returns

Spreading investment across different asset types to reduce the impact of any one failing

Dividing investments equally between only two asset classes — shares and bonds

Only investing in assets issued by the local government for guaranteed safety

Your entire portfolio is in one company's shares and that company collapses. Diversification would have:

Limited your loss since other holdings would have retained their value

Prevented the loss entirely since diversified portfolios cannot go to zero

Had no effect since all assets in a market fall equally when one company collapses

Doubled your loss since diversification amplifies returns in both directions
