Abstract
We introduce the Global Fear of Missing Out (FOMO) Index, a monthly sentiment measure built from Google Trends data, capturing a persistent psychological force driving global financial markets. The index exhibits high persistence and a robust inverse relationship. To contextualize the economic magnitude of our findings, we clarify that a 10 % increase in the Global FOMO Index is associated with a 1.7 %–2.0 % decline in monthly stock returns, a 2.02 %–2.1 % drop in realized volatility, and a 4 % reduction in the Sharpe ratio. These impacts are amplified in democratic countries, underscoring a political dimension. The Global FOMO Index thus emerges as a novel sentiment metric, explaining cross-country and time-series variation in market dynamics and offering fresh insights into the interplay of psychology, politics, and finance.
