5 Things Young Investors Should Learn Early

Young investors have one advantage that cannot be bought or borrowed: time. But time alone does not build wealth—what you do with it does.

Starting your investing journey in your twenties or thirties puts you in a genuinely powerful position. Compounding works quietly and relentlessly over long periods, and the earlier you give it fuel, the more dramatic the results. But starting early without the right foundation can just as easily lead to costly mistakes—chasing trends, panicking during downturns, paying too much in fees and letting short-term thinking undermine a long-term strategy.

These five principles will not tell you which ETF to buy first. They will do something more valuable: they will shape how you think about money for the rest of your investing life.

1. Save First: The 15 Percent Rule

Before any investment strategy can work, there has to be money to invest. A strong target for young Canadians is saving at least 15 percent of net income. That number is not arbitrary—it reflects the savings rate that gives compounding enough raw material to produce meaningful long-term results.

Building that habit early also creates discipline that carries through every stage of your financial life. Before investing aggressively, make sure a proper emergency fund is in place. Three to six months of living expenses held in a high-interest savings account gives you the stability to stay invested during market downturns without being forced to sell at the wrong time. That buffer is not idle money—it is the foundation that makes everything else possible.

2. Understand Risk And Return

Higher expected returns come with higher volatility. That is not a design flaw—it is how markets work. The reward for tolerating uncertainty is long-term growth. The price of avoiding uncertainty is lower returns.

Market declines are a normal and necessary part of long-term investing. Corrections happen. Bear markets happen. Portfolios drop 20, 30, even 40 percent during particularly difficult periods—and then, historically, they recover. Understanding this intellectually before it happens to you makes it far easier to stay the course when it does.

The Little Book of Common Sense Investing by John C. Bogle is the clearest explanation of why low-cost, broadly diversified index investing consistently outperforms most active strategies over time. It is a short read and one of the most useful things a new investor can spend an afternoon on.

3. Ignore Market Noise

Financial media is engineered to provoke reaction. Headlines are written for clicks, not clarity. The cycle of fear and euphoria that plays out across news cycles and social media has very little to do with the long-term trajectory of a well-constructed portfolio—and very much to do with short-term emotional responses that cost investors real money.

The discipline of ignoring noise is harder than it sounds. When the people around you are excited about a trending stock or sector, the pull toward participation is real. When markets drop sharply and the headlines are alarming, the pull toward selling feels rational and protective. Smart long-term investors learn to recognize both impulses and sit on their hands anyway.

When others are panicking, that is often the most important time to continue contributing—not the time to stop.

4. Understand Your Own Psychology

Behaviour determines most long-term investing outcomes. Not intelligence, not market timing, not picking the right fund. Behaviour.

The most common and costly mistakes young investors make are not analytical errors—they are emotional ones. Selling during a downturn and missing the recovery. Chasing last year’s best-performing sector into this year’s worst one. Checking a portfolio daily and making impulsive decisions based on short-term movement. Waiting for the “right time” to invest and watching years of compounding disappear.

The Psychology of Money by Morgan Housel is one of the most accessible and genuinely useful books written on this subject. It does not tell you what to invest in. It explains why the way you think and feel about money is likely the biggest determinant of your financial outcomes—and what to do about it.

5. Be Thoughtful About Financial Advice

Not all financial advice is created equal, and young investors are right to approach the industry with a degree of healthy skepticism. Many advisors operate under commission-based models where the products they recommend generate income for them regardless of whether those products are best suited to you. High-fee mutual funds, deferred sales charge products and complex investment vehicles with layered costs all quietly erode long-term returns in ways that are not always easy to see.

This does not mean all financial professionals lack integrity—many are genuinely excellent. But it does mean you should understand how your advisor is compensated, ask about fee structures directly and prioritize low-cost diversified ETFs as the core of your portfolio. When professional advice is warranted, fee-only fiduciary advisors are incentivized to give recommendations that serve your interests rather than their own. Even a one percent difference in annual fees, compounded over thirty years on a growing portfolio, can represent a staggering difference in final wealth.
