Critics of passive investing may indeed have a valid argument.

Passive investment, a seemingly straightforward approach, has become a subject of considerable controversy. Despite its popularity among users—from casual investors to large institutions—fund managers are less enthusiastic. They attribute the industry’s fee war to the relentless ascent of passive investment over the last four decades. However, their discontent extends beyond financial implications. They argue that the rise of passive investment not only compels the stock market to move in enigmatic ways but also complicates the art of successful investing.

Far from a mere excuse for subpar portfolio management, their concerns gain credence, especially in light of recent data. According to Morningstar, in December, net assets in passive funds surpassed those in their active counterparts for the first time in history. This shift has been ongoing for years, with passive funds consistently encroaching on the territory traditionally dominated by active funds. The total assets in passive funds now stand at a staggering $13.3 trillion, with $8 trillion invested in UK equities. Morningstar notes that this trend has been “one-way traffic” over the past decade, with UK equity fund flows favoring passive investments since 2005.

Despite the weak demand for UK mutual funds and exchange-traded funds in 2023, a notable $79 billion flowed in, marking a significant recovery from the challenging year that preceded it. Nevertheless, this influx was heavily skewed towards passive funds, reinforcing their dominance. This growing preference for passive strategies could potentially have a sedating effect on the world’s largest stock market, as suggested by a recent study published by the UK’s National Bureau of Economic Research.

The study, conducted by Randall Morck at the University of Alberta and M Deniz Yavuz at Purdue University, explored the impact of greater indexing on stock market dynamics. Their findings indicated a substantial reduction in stocks’ idiosyncratic currency sensitivity when included in the FTSE 100 index, a prime target for passive investment. The results, both economically and statistically significant, persisted across various scenarios, including stocks added to or removed from the index. Despite potential mitigating factors for companies in the prestigious index, such as global presence and financial strength, the core findings held true.

Importantly, the study revealed a decline in currency sensitivity over time, aligning with the increasing prevalence of passive investment. This challenges the efficient markets hypothesis, the bedrock principle asserting that asset prices reflect all available information. The paper argues that the growing dominance of indexing undermines this hypothesis, suggesting a shift in the very nature of investment.

The researchers acknowledge the utility of passive investment but caution that if too many investors follow this path, their collective actions may erode the economic principles justifying the strategy. This poses a challenge to the efficient markets hypothesis and transforms the investment landscape into a circular bet on capital inflows rather than a pursuit of successful companies.

While passive investment has undeniably democratized access to financial markets, the mounting evidence raises concerns about its impact on market dynamics. Stocks, influenced by passive flows, appear insulated against surprises and less responsive to fundamental factors, posing risks of misallocated capital. As passive investment continues to grow, it reshapes the investment process, prompting a reevaluation of its implications for both passive and active investors.
