The affinity of American investors for the stock market has reached unprecedented levels. JPMorgan strategists Jan Loeys and Alexander Wise have observed a consistent increase in the allocation of U.S. households and nonprofit organizations to domestic equities over the past forty years, culminating in an allocation nearing 41% this year.
This figure not only marks a significant divergence from global trends but has also been a driving force behind the remarkable expansion of the U.S. stock market, which now represents 64% of global market capitalization. This steadfast commitment to equities has been a key contributor to the U.S. market's exceptional performance, enhancing its valuation relative to international markets and underpinning the notion of "U.S. Exceptionalism."
Despite the 41% equity allocation appearing modest compared to the traditional 60/40 equity-bond split advocated by many advisors, it signifies a notable upward trajectory from the 10% low in the early 1980s. This growth trajectory starkly contrasts with the static equity allocations seen in other developed nations, where countries like Japan, Germany, and France have seen little to no increase in their equity investments over the same period.
The concentration of stock investments is even more pronounced among the wealthiest 5% of U.S. households, which allocated 57% of their portfolio to equities, demonstrating a strong preference for a 70/30 split between stocks and bonds by the end of 2018. This trend underscores a robust equity culture in the U.S., supported by the public's recognition of the historically high returns offered by equities, averaging around 10.8% annually. This optimistic outlook encourages investors to maintain or increase their market positions rather than cashing out during rallies.
Loeys and Wise suggest that this enduring attraction to equities may stem not only from strategic asset allocation decisions but also from a cultural tendency to "go with the flow," influenced by a perception of lower risk in U.S. equities, the influence of popular investment literature, and the ease of trading provided by the proliferation of market-tracking funds.
However, the strategists caution that this enduring preference for stocks may not be permanent. Shifts in investor expectations or the emergence of compelling alternative investment options could redirect capital flows away from equities in the coming years. Additionally, demographic shifts and macroeconomic factors could necessitate a gradual pivot towards more conservative investments, such as cash and bonds, although such a transition appears to be on a distant horizon.
