S&P 500 Call Option Volume Hits Record 4 Million Contracts as Bullish Bets Reach Historic High

S&P 500 options activity hit a record, with call volume surpassing 4.02 million contracts on Aug. 4, signaling an exceptional surge in bullish positioning. The article says traders are chasing upside after a strong summer rebound, while floor traders described a one-way flow of buy orders. UBS derivatives research remained constructive and set a year-end S&P 500 target of 8,100, implying further upside. The commentary also notes hedge funds bought $4.8 billion of U.S. equities in the week ended July 31, the second-largest weekly purchase since 2008, reinforcing the bullish backdrop. However, some market commentators warned that dealer hedging and options-market mechanics may be amplifying gains beyond what fundamentals justify. Overall, the piece reflects strong speculative demand and supportive institutional flows, but also elevated risk of distorted price action and near-term volatility.
