Index funds: passive investing explained

The lesson in plain words

The same lesson as the slides above, written out in full.

1. Index funds: passive investing explained

Welcome. In this lesson we will keep things simple and look at one of the most popular ways ordinary people invest: the index fund. The whole idea is that instead of trying to outsmart the market, you just quietly own a broad slice of it. By the end you will understand how these funds work and why so many long-term investors like them.

• An index fund simply tracks a market index instead of picking stocks
• It is a passive approach: match the market, do not try to beat it
• You get instant diversification across many companies at once
• Costs are usually very low, which matters more than most expect
• A common starting point for long-term, hands-off investors

A quick note: This is financial education only, not financial advice. Any figures used are illustrative examples to explain the idea, not predictions or recommendations. Always do your own research and consider speaking with a qualified professional before making any investment decision.

2. How an index fund actually works

So how does the magic happen? An index is really just a published list of companies, usually weighted by how large each one is. The fund managers do not sit around picking favourites. They simply buy those same companies in the same proportions, so the fund goes up and down almost exactly in step with the index it follows.

• An index is just a defined list of companies, weighted by size
• The fund holds those same companies in the same proportions
• When the index changes, the fund rebalances to match it
• No manager is guessing winners, it simply mirrors the list
• Your return roughly equals the index return minus a small fee

3. Why low fees compound in your favour

Here is the part that surprises most people. A fee that sounds tiny, like 1% a year, does not stay tiny. Because it is charged every single year, it compounds and can quietly hand away a large chunk of your growth over decades. Since index funds usually cost very little to run, more of the market's return stays with you.

• A fund's expense ratio is the yearly fee you pay to hold it
• Even a 1% difference compounds into a large gap over decades
• Fees are charged whether the fund wins or loses
• Lower cost means more of the return stays in your account
• This is why passive funds often keep more for the investor

4. Index funds versus active funds

The main alternative is an active fund, where a manager tries to beat the market by picking and trading holdings. That work costs more, and over the long run most active funds do not actually beat their index. One caution: some index products are leveraged or inverse, meaning they use borrowing and derivatives, which brings ethical concerns around interest and excessive uncertainty. Titan's own approach sticks to plain shares and long options with clearly defined risk.

• An active fund pays a manager to pick and trade holdings
• That effort means higher fees and often more turnover
• Most active funds fail to beat their index over the long run
• Leveraged or inverse index products use borrowing and derivatives, which raise concerns over riba and gharar
• Titan's own approach favours plain shares and long options with defined risk
