What is Passive fund?

A fund that holds the benchmark it's tracking — no stock picking.

A passive fund simply holds the index it tracks, with no manager trying to pick winners — it owns the whole benchmark and accepts its return. Index funds and most index ETFs are passive; the philosophy is to capture the market rather than beat it.

The reward for this humility is very low fees and, over the long run, results that beat most active funds. By not paying for research, not trading much, and not betting on the manager's judgement, a passive fund keeps costs to a minimum — and because those costs are the main reason active funds underperform, low cost quietly does most of the work. Passive investing is the evidence-based default for people who don't want a second job analysing stocks.

Doing less, and keeping more

Of a 10% market return, a passive fund charging 0.05% hands back 9.95% while a 0.9% active fund keeps 9.1% — before any stock-picking even helps. Low cost does most of the work.

For example

A passive fund tracking the global stock market just owns all of it, charges a sliver in fees, and quietly outperforms most stock-pickers over time.

Why it matters to you

Passive funds matter because they flip the usual assumption: doing less, and paying less, tends to win. Decades of evidence show that most active managers fail to beat the market after fees, so simply owning the market cheaply outperforms the majority of professionals. For an ordinary investor, passive funds turn a hard, time-consuming problem into a one-decision, low-cost solution — which is why they now hold a large share of the world's invested money.

Assuming passive means no risk

Passive funds remove the manager and cut costs, but they don't remove market risk — a passive stock fund falls right along with the market in a downturn. 'Passive' refers to the strategy of tracking an index, not to safety. You still need an allocation and time horizon you can hold through the drops the index will inevitably have.

Frequently asked questions

What is a passive fund?

A passive fund tracks an index by holding its securities, rather than employing a manager to pick investments. It aims to match the market's return, not beat it, which keeps fees very low. Index funds and most index ETFs are passive funds.

What's the difference between passive and active funds?

A passive fund tracks an index and accepts its return at very low cost; an active fund pays a manager to try to beat the index, charging more. Most active funds underperform their benchmark after fees over the long run, largely because of that higher cost, which is why passive funds have grown so popular.

Why has passive investing become so popular?

Because the evidence favours it: most active managers fail to beat the market after fees, so cheaply owning the market has outperformed the majority of professionals over time. Passive funds are simple, low-cost, and diversified, turning a hard problem into a one-decision solution — appealing to most investors.
