The timing of investing in an index is important. Markets are back to high expectations, with high multiples and double-digit earnings growth forecasts for MSCI World for the next two years, on top of peak margins. This brings risk for passive investors, in our view. Three consensus trades dominate today’s markets: being invested in the American economy, owning obvious artificial intelligence plays and positioning for a soft or no landing in the U.S. If anything other than this consensus view prevails, index investors may find themselves in relative difficulty.

For many investors, opting to invest in an index has been an easy decision these last years. An era of historically low interest rates and loose monetary policy meant that as the U.S. 10-year Treasury yield declined from 4% in 2010 to just 0.5% in 2020, the S&P 500 Index’s price-to-earnings (PE) forward multiple rose from 14x to 18x.1 Since 2022’s market sell-off, the S&P 500 PE has continued its upward climb and is back at 21x – almost 40% above its 2022 low.2 As a rising tide has helped lift all boats, index investing has reaped substantial rewards; S&P Global’s SPIVA research shows that in the U.S., over one, three-, five-, 10- and 15-year periods, passive investing has beaten most large-cap actively managed funds.3 For the average investor, the transparency and liquidity offered by index investing, as well as its lower cost, have also added to the appeal.
While active versus passive is a well-worn debate, it needn’t be an either/or decision. In fact, we would argue that there’s a strong case for both index investing and active management to co-exist in portfolios. How they are balanced can be determined by an investor’s investment objective, preferred time horizon, and appetite for risk – whether the definition is tracking error or losing money.
The active/passive conundrum
The decision to opt for passive investing is still an active decision. According to the Index Industry Association4, there are over 3 million stock indices in the world – over 50 times more indices than stocks5! Choosing to track an index, or combination of indices, still requires an investor to make an active decision.
Then there’s risk. By owning more stocks via an index fund, an investor may hope to benefit from the positive effects of diversification. But is owning everything regardless of quality or valuation really the best way for investors to diversify a portfolio? Equally, with the focus of so many managers and investors on relative risk, the market has provided a comfortable place to take shelter. But is weighting an investment based on size sensible, given that most widely recognised and invested indices are typically market-cap weighted? An investor may hope for the wisdom of the crowd but instead get a crowded trade. In bull markets, market-cap weighted indices in particular can become increasingly biased and lopsided as valuations for those stocks perceived as "winners" are stretched beyond fundamental rationality, and the weights of the “winners” mechanically increase in the passive indices. Recent research6 from Morgan Stanley observed that S&P 500 concentration is at a historical extreme, increasing its vulnerability to a steep correction as the cycle or “theme du jour” turns.
This risk is further compounded by the connected aspects of the largest stocks that dominate several equity indices. In the S&P 500, the recent fortunes of some of the largest market constituents have been driven by euphoric earnings expectations around the promise of generative artificial intelligence. Of course, an investor may attempt to diversify some of this thematic risk by tracking a global index, but with the U.S. weighting in global indices at an all-time high7, they may not achieve the diversification expected. Attempting to work around this by using an equal-weighted alternative may come at the expense of missing the opportunity that recent distortions have presented.
The benefit of being selective
While passive funds provide broad-based exposure and nimble, cheap access to tactical themes, there is still an opportunity to be selective – particularly given indices’ biases. When stock prices become disconnected from fundamentals, skilled stock pickers can take advantage — that is, of course, provided they have the luxury of a longer time horizon if a lopsided multiples-powered bull run still has momentum.
As with passive options, investors face a plethora of choice when it comes to picking an active equity manager, not least because the tracking error constraints some active managers have in place can reduce the active/passive “balance” an investor may be seeking to achieve. We believe that our team’s concentrated, benchmark-agnostic strategies offer a useful counterbalance to index investing. Why?
Independent thinking
In 2016, an article in The New Yorker8 expressed a concern that with the rise of passive investing, investment decisions could be “increasingly on autopilot”, as money pours into the largest companies irrespective of traditional investment considerations such as price, volatility or fundamental conviction. In an environment where the biggest companies make up a larger share of the index, we believe a bottom-up, high quality strategy focusing on steady, resilient compounding can serve as a useful complement – particularly should the market take a knock – and offers investors a way to differentiate from the crowd. As Benjamin Graham commented, “There are two requirements for success in Wall Street. One, you have to think correctly; and secondly, you have to think independently.”
