Investing, from the ground up

What is an ETF?

Think of an ETF (Exchange Traded Fund) as a pre-packaged basket of investments. Instead of going to the stock market and buying a single share in one company, you buy a single “unit” of this basket, which instantly gives you a tiny slice of dozens or hundreds of companies all at once.

ETFs vs. Shares vs. Managed Funds vs. Super

Shares: Buying into one specific company (like Apple or Commonwealth Bank). If they have a bad year, you have a bad year.

Managed Funds: An older-style version of a basket. You usually buy in directly with the fund manager, often with more paperwork, and it’s typically priced just once a day.

Superannuation: Not an investment itself, but a tax-sheltered “bucket” where your retirement money lives. Your super fund then uses that money to buy shares, property, or even ETFs.

ETFs: The modern middle ground. It’s a diversified basket like a managed fund, but it lives on the stock market — meaning you can buy or sell it in seconds on your phone, just like a regular share.

What is “The Market” at a Basic Level?

The stock market is essentially a giant digital auction house where people buy and sell tiny fractions of public companies. Prices move on a simple rule: if more people want to buy a company than sell it, the price goes up; if everyone is selling, it drops.

Why ETFs Suit People Starting Out

To buy 200 different companies individually, you’d need thousands of dollars and pay a trading fee for every single one. An ETF lets you skip that — you get instant variety in one transaction, which helps protect your money if one or two companies in the basket hit a rough patch.

Index Tracking Explained

Most ETFs don’t hire an expensive fund manager to guess which stocks will win. Instead, they run on autopilot by “copy-pasting” an official list of companies — like the 200 biggest businesses in Australia. The ETF simply holds everything on that list, so your investment mirrors the performance of that whole slice of the economy.

Fees & Why Small Percentages Matter

ETFs charge an ongoing management fee, which is quietly taken out of the fund’s value behind the scenes (you never get a bill for it).

A 0.1% fee versus a 0.7% fee sounds tiny on paper. But because of how compounding works, a higher fee takes money out of your account that would otherwise have stayed invested and earned its own growth. Over 20 years, that small gap can add up to thousands in growth you never got to keep.

Distributions vs. Dividends

When the companies inside your ETF basket make a profit, they pay out cash called dividends. The ETF provider collects all these tiny payments, bundles them into one package, and drops it into your account. This payout is called a “distribution.” (A distribution can also include other income and realised gains, not just dividends — but for most share ETFs, dividends are the bulk of it.)

What Owning “Units” Involves

When you buy an ETF, you don’t directly own the underlying shares (you can’t walk into a Microsoft shareholder meeting). You own a “unit” of the trust that holds them: the trust legally owns the shares, and you legally own a slice of the trust.

Asset Classes & Geographic Exposure

Every fund tells you where its money goes using two main filters:

Asset Class: What kind of thing it’s buying — shares (typically for growth), bonds / fixed income (typically for stability), or cash.

Geographic Exposure: Where in the world the money goes — just Australia, the US, or spread across global and emerging markets.

Diversification vs. Overlap

True diversification means not putting all your eggs in one basket. A common trap, though, is buying three different ETFs thinking you’re diversified, when underneath they’re all holding the same companies.

For example, if you buy a “Global Top 100” ETF and a “US Tech” ETF, you’re likely doubling or tripling down on the exact same companies — Microsoft, Apple, Nvidia — without realising it.

Currency Hedging (Hedged vs. Unhedged)

If you buy an ETF that holds US companies, you’re also exposed to the US dollar without necessarily meaning to be.

Unhedged: Your investment value moves on two things — the companies and the exchange rate. If the Aussie dollar falls, your US investments are actually worth more in Australian-dollar terms.

Hedged: The provider uses currency tools behind the scenes to cancel out the exchange-rate swings, so you mostly experience the performance of the companies themselves.

Income vs. Growth

Some ETFs lean toward growth — companies (often in tech or innovation) that tend to reinvest rather than pay much cash, in the hope of growing in value over time. Others lean toward income — more established companies, like banks or utilities, that pay steadier, regular dividends.

Time Horizon & Volatility

On a daily chart, the stock market looks like a chaotic zig-zag — that’s volatility. Zoom out to a 10-year chart and those daily bumps usually smooth into a steadier trend (usually — it’s a historical pattern, not a guarantee; there have been flat and falling stretches even over years). This is why people think about time: money you might need back in the next year or two sits uneasily in something that can swing, while money you can leave alone for a decade has room to ride the bumps out.

The Danger of Over-Complication

It’s easy to get excited and end up holding 15 different niche ETFs — a robotics one, a space one, a clean-energy one. The catch is that this often creates accidental overlap (the same big companies turning up across all of them), higher combined fees, and a portfolio that’s hard to keep track of. This is why many investors lean toward a few broad funds rather than a shelf of niche ones: fewer overlaps, lower combined fees, and less to follow.

How Funds Combine (Core & Satellite)

One framework people use to think about a portfolio is “core and satellite.” The core is the broad, diversified foundation — often a couple of cheap index funds covering big slices of the market. The satellites are smaller positions added around the edges: a particular theme, say, or a single company someone has conviction in. The idea is that the broad foundation does the heavy lifting, so the smaller bets sit on top without the whole structure resting on them.

Myth: “If the ETF company goes bankrupt, my money disappears.”

The ETF provider (like Vanguard) doesn’t hold your money on its own corporate books. By law, the assets are held separately by an independent “custodian.” If the provider went under, your investments would remain safely held there, to be wound up or moved to another provider.

Myth: “If nobody is trading an ETF on a given day, I won’t be able to sell my units.”

Unlike regular shares, selling an ETF doesn’t depend on finding another ordinary person to buy your units. ETFs use specialised partners called “market makers” who sit on the exchange and create or buy back units as people buy and sell — so there’s normally a price available even when trading is quiet.
