CryptoWorld News reports that on April 7, Citadel Securities reported that retail investors net sold US stocks and options last week, contrasting with the rare trend of continuous buying over the past years. Net outflows in March decreased by 55% compared to February and by 70% from the peak in January. Options activity shifted to a defensive stance, with increased demand for downside protection. Historically, this retail selling behavior often signals a strong short-term rally in the S&P 500 index, with an average gain of 4.1% over the next two months. This shift comes amid market volatility triggered by rising oil prices and conflicts in Iran in March, leading to a 5% decline in the S&P 500 this year, while Brent crude oil prices surged by 80%.
