I’ve been interested by the state of passive investing because the message “simply purchase the S&P 500” grew to become the predominant narrative lately. This thought was first posed to me by our former GIC chief and Presidential candidate Ng Kok Tune just a few years in the past, and I haven’t been in a position to shrug it off since.

In my latest journey to Omaha for the 2025 Berkshire Hathaway AGM, I had the fortune to fulfill with many clever traders and thought leaders as we talked about shares and the rising theme of passive traders who merely purchase index funds each month with out pondering. Is that this “purchase and neglect” technique sufficient? How do these form the markets, and are they inflicting a much bigger valuation hole for firms who aren’t within the massive market indices (but)? May the brand new 10X technique be to seek out worthwhile small-cap firms which are quickly rising and put money into them earlier than they get included within the indices?
I spoke with Michael Inexperienced, chief strategist of Simplify Asset Administration on the VALUExBRK convention the day earlier than, who calls passive index investing “The Biggest Story Ever Bought”. He argues that passive is not passive and is as an alternative the best con ever pulled on traders. The beneath slides are snippets I’ve minimize from an earlier model of his presentation, which will be discovered right here.


The argument that the rise of passive investing not solely distorts the markets, however will result in chaos just isn’t precisely new, however we lastly have extra statistics to again this speculation up. Apparently, this sentiment was additionally echoed by Warren Buffett in an earlier 1982 letter to shareholders the place he expressed considerations in regards to the detachment from underlying enterprise valuations that the rise of index funds may deliver.

Howard Marks additionally wrote a memo on this earlier this 12 months, and I quote some noteworthy sections from it that acquired me pondering:
“The best bubbles often originate in reference to improvements, largely technological or monetary, they usually initially have an effect on a small group of shares. However generally they lengthen to complete markets, because the fervor for a bubble group spreads to every part.
In the same vein, heated shopping for spurred by the commentary that shares had by no means carried out poorly for an extended interval triggered inventory costs to rise to some extent from which they had been destined to do exactly that.
The S&P 500 declined in 2000, 2001, and 2002 for the primary three-year decline since 1939, throughout the Nice Melancholy. As a consequence of this poor efficiency, traders abandoned shares en masse, inflicting the S&P 500 to have a cumulative return of zero for the greater than eleven years from the bubble peak in mid-2000 till December 2011.
The purpose is that when shares rise too quick – out of proportion to the expansion within the underlying firms’ earnings – they’re unlikely to maintain on appreciating. Michael Cembalest has one other chart that makes this level. It reveals that prior to 2 years in the past, there have been solely 4 occasions within the historical past of the S&P 500 when it returned 20% or extra for 2 years in a row. Within the final two years, it’s occurred for the fifth time. The S&P 500 was up 26% in 2023 and 25% in 2024, for the perfect two-year stretch since 1997-98. That brings us to 2025. What lies forward?”
That is an commentary I’ve repeatedly expressed on my social media channels. The latest market actions are something however regular. I’m not sensible sufficient to know all of the solutions, however Howard Marks provides a clue by trying again into historical past:
“There’s a robust relationship between beginning valuations and subsequent annualized ten-year returns. Greater beginning valuations constantly result in decrease returns, and vice versa.
Immediately’s P/E ratio is clearly nicely into the highest decile of observations. In that 27-year interval, when folks purchased the S&P at P/E ratios consistent with in the present day’s a number of of twenty-two, they at all times earned ten-year returns between plus 2% and minus 2%.”
Sadly, I didn’t get an opportunity to ask Warren Buffett about this throughout the 2025 Berkshire Hathaway AGM on the microphones, so I believed I’d ask the subsequent finest individual: Markel’s CEO Tom Gayner. His observe file is impeccable, and he’s an investor whom I drastically respect for each his observe file and life knowledge. His response?
“It would nicely be that this period we’ve been by (of outperformance by the S&P 500) may be very troublesome for the S&P to maintain up with.
It could look very completely different than what it has achieved within the final 5, 10 or 20 years.
I spend my time to consider every particular person enterprise and might I depend on them to relentlessly compound our capital, and I strive to think about that as independently to the S&P as I probably can.”
I typically get requested by readers whether or not merely shopping for the S&P 500 each month and doing dollar-cost averaging shall be ample. My stance is fairly clear, and I’ll say this: you must make – and settle for – the choice for your self that may decide your future investing outcomes.
I’ve discovered these memos and insights to be helpful for me, and hope it provides you one thing to consider as making a decision on the trail you wish to take along with your cash.
As an investor myself, I don’t consider that the trail to wealth lies in doing what everybody else is doing. I’ve by no means been a believer of merely shopping for the indexes – as an alternative, I favor to seek out the highest-quality firms inside it and purchase them when they’re buying and selling at undervalued costs available on the market.
The S&P500 might have traditionally returned 10 – 11% over the past 40 years, however previous efficiency just isn’t a assure for future efficiency and there’s no telling how the longer term will appear to be.
I’ve little doubt that many US-listed firms will proceed to develop and dominate. I’m personally invested in a number of of them – together with Alphabet, Amazon and Palantir. However I purchased them solely at strategic timings, and never by an index fund.
One factor is for positive – my portfolio didn’t cross $1M by shopping for the index each month, and even when I may flip again time to vary my methods and purchase the S&P 500 each month as an alternative, there’s no manner it will have gotten me to $1M both.
In fact, simply because I could not do it with the S&P500 does not imply you may't. In spite of everything, the S&P500 returned 300% positive aspects within the final decade, so anybody who had $330k to begin with then may need yielded a very completely different consequence.For the file, I began investing with $20k in 2014. It wasn't till 2017 once I hit $100k, and even when I had the foresight (and guts) to take a position all of it within the S&P500 then, my returns nonetheless would not be anyplace near $1M.
As an alternative, I favor to be considerate about what’s extra more likely to beat the markets within the long-run. I’d a lot quite comply with the playbook of legendary traders I respect – together with Buffett, Gayner and extra – and put money into undervalued firms that may compound sooner and better than the market indexes.
Whereas I do not know the place the S&P500 will go from right here, I shall hearken to Gayner’s recommendation and function “independently of the S&P500”.
How about you guys?
