According to Bloomberg, a "Dispersion Trade" strategy is gaining traction in the US equity options market amidst a diverging AI narrative, volatile oil prices, and soaring US Treasury yields. The core of this strategy involves going long on individual stock options and short on index options, aiming to profit from the difference between individual stock and index volatilities. The current market environment is believed to offer a rare entry window, as the contraction in individual stock implied volatility makes position-building costs relatively low, and the divergence in S&P 500 constituent stock movements has risen to the 95th percentile over the past 30 years. However, some market participants warn that the strategy may already be overcrowded.
