Index funds are great tools to pursue your investment goals. While they’re often sold as passive, and that’s probably true if you can find one that covers all global markets, some are very narrow in focus and guided by rules that can make them more active than passive.
This can be a trap for investors, especially if the index fund they choose doesn’t take off and attract a consistent flow of funds that makes it sustainable for the manager.
With that in mind, we take a look some various quirks around index funds to look out for, and highlight the reality that we’re all faced with making active choices as investors.

Synopsis
Unpacking “Passive” Investing: The Active Choices Behind Your Index Fund
In “How Passive is Your Index Fund? | What’s the Risk? 29,” we challenge the common perception of passive investing, revealing the surprising degree of active decision-making involved in index funds. The video begins by referencing Burton Malkiel’s ideal of a truly passive fund [00:57], contrasting it with the reality of over 3 million available indices.
The discussion highlights the numerous “active” choices investors face, including regional weighting [03:22], country classification discrepancies between index providers [03:39], and market capitalization focus [03:45]. Learn how varying rules for factors and themes like ESG can significantly impact index composition [04:05].
We reveal how index provider decisions directly affect returns, even for seemingly similar categories like Australian small-cap indices [05:14]. Show the “active waiting” periods for companies to enter an index, potentially causing investors to miss substantial returns [08:12]. The video also critiques fund managers for chasing investment fads, such as the shift to ESG funds, which can undermine investment integrity [09:13].
Furthermore, the discussion covers the impact of ETF closures on investors, forcing potentially costly sell-offs [10:54]. Finally, the video sheds light on the active trading decisions within “passive” funds, particularly during index reconstitution, which can lead to wider spreads and negatively impact investor returns [11:53]. This insightful analysis emphasizes that choosing an index fund requires careful consideration, as selecting narrowly defined indices can be detrimental to long-term performance [12:46].
