Active vs passive: two ways to run a fund

Q: If some active funds beat the index, why not pick those?

Because you’d have to identify them before the good run, not after. Strong past performance has proven a weak guide to future performance, and the ones that lag still charge their higher fee along the way. That difficulty — not a dislike of managers — is the case people make for indexing.

Part of Choosing & comparing

A passive fund quietly copies a list. An active fund pays a manager to try to beat that list. That single choice drives most of what you end up paying.

What each one is doing

A passive fund has a simple job: copy a published list — its — and keep copying it. No opinions, no stock-picking, no trying to be clever. An active fund does the opposite: a manager and their team research companies and choose what to hold, aiming to do better than that same index. Most ETFs a beginner meets are passive.

The cost gap

Opinions are expensive. An active fund pays for managers, analysts and more frequent trading, and that shows up in a noticeably higher yearly fee (the ). A passive tracker just follows a list, so it can charge a small fraction of a percent. That fee gap is charged every single year you hold — and it comes out whether the manager has a good year or a bad one.

The humbling record

Here is the part that surprises people. The long-run record of active management is humbling: over long stretches, most active funds have not beaten their benchmark index once their higher fees are taken out. Some do, and some do brilliantly — the hard part is knowing in advance which ones, since past winners often don’t repeat. That is the whole reason low-cost index tracking became so popular.

So which is which?

Neither is a villain. Active management can make sense in corners of the market that are harder to track, and plenty of thoughtful investors use both. But for a beginner wanting broad, cheap exposure without picking a manager, passive is the simpler starting point — which is why it dominates the ETF world. We explain the two approaches so you can weigh them; we’d never tell you which to buy.

Common questions

Are all ETFs passive?

Most that a beginner meets are, but no — active ETFs exist too. The ‘ETF’ part describes the wrapper (it trades on an exchange, all day); ‘passive’ describes the strategy (copy an index). The two labels answer different questions.
