Diversification enables you to reduce the risk of your portfolio without sacrificing potential returns. Once your portfolio has been fully diversified, you have to take on additional risk to earn a higher potential return on your portfolio.

Understanding risk and return

Some investments are riskier than others – there’s a greater chance you could lose some or all of your money. GICs and bank deposits carry low risk because they are backed by large financial institutions. With GICs and deposits you also have the additional protection of deposit insurance on amounts up to $100,000 if your financial institution goes bankrupt. With these low-risk investments you are unlikely to lose money. However, they have a lower potential return than riskier investments and they may not keep pace with inflation.

Over the long-term, bonds have a potentially higher return than CSBs and GICs, but they also have more risks. Their prices may drop if the issuer’s creditworthiness declines or interest rates go up. Learn more about the risks of bonds.

At the other extreme, common shares are very risky because they have no guarantees and shareholders are paid last if the company is in trouble or goes bankrupt.

Investors must be paid a premium, in the form of a higher average return, to compensate them for the higher risk of owning shares.
