Retail investors in the U.S. have reduced their stock market activity, with weekly purchases declining by approximately 30% due to escalating geopolitical tensions in the Middle East and rising inflation concerns. According to a report by JPMorgan Chase, net retail inflows over the past five trading days fell to $6.7 billion, below the 12-month average of $7.1 billion. Additionally, inflows into exchange-traded funds (ETFs) have decreased by 22%, totaling $6.3 billion. This shift indicates a cooling risk appetite among retail investors as they navigate the current economic uncertainties.
