America's Nest Egg: Stocks Dominate Savings
24 Oct
Summary
- Americans hold record 48.2% of financial assets in stocks.
- Richest 1% own half of all stocks and stock funds.
- High stock share historically signals lower future returns.
Household financial assets in the U.S. have reached an unprecedented level of stock market exposure, with stocks comprising 48.2% of assets in the second quarter. This figure, the highest on record dating back to 1945, surpasses previous peaks seen during the dot-com bubble and meme-stock frenzy.
The concentration of stock ownership is highly uneven. The wealthiest 1% of households own approximately half of all stocks and stock funds, while the top 10% hold 88%. The bottom 50% of households collectively own only about 2% of stocks.
Historically, a high proportion of stock holdings within portfolios has been linked to lower median annual returns in the subsequent decade. When stocks represented less than 20% of assets, the S&P 500 gained a median of 11% annually over the next ten years. However, when the share topped 30%, annual gains fell to around 5%.
This surge in stock allocation suggests investors may be exposed to more risk than intended. For instance, an investor with a 60/40 stock-bond portfolio at the start of 2023, without rebalancing, would now hold approximately 73% in stocks. Despite this increased market exposure, household balance sheets currently possess sufficient room to absorb market volatility, with assets still significantly outweighing liabilities.
