US households reach record stock ownership amid Nasdaq 100 volatility shifts

US households are currently holding a record concentration of wealth in stocks, with Federal Reserve data showing that corporate equities account for 48.23% of financial assets. This level of exposure is significantly higher than the peak reached during the dot-com bubble, which sat at approximately 27%.

This high concentration, driven largely by the artificial intelligence sector, has led to unusual dynamics in the Nasdaq 100 options market. The put-to-call volatility skew—a measure of the cost of downside protection relative to upside bets—has dropped to historic lows. In some instances, the skew has inverted, meaning traders are paying higher premiums for calls (upside bets) than for puts (downside hedges).

Analysts note that while the Nasdaq 100's current price-to-earnings ratio is high, it does not yet mirror the extreme valuations seen during the March 2000 peak. However, the lack of demand for downside protection suggests a high level of market complacency that could leave investors vulnerable to sudden earnings downgrades or shifts in capital expenditure by major technology firms.
