A new paper by Robert Jackson Jr and Joshua Mitts suggests that someone may have profited from insider knowledge of the October 7th attack on Israel by Hamas. The authors found a surge in short sales of an exchange-traded fund (ETF) tracking Israeli shares, with a significant increase in activity just days before the attack. Other securities also showed suspicious patterns, such as a rise in options contracts expiring on October 13th. The study has prompted an inquiry by Israel's securities authority, although critics suggest alternative explanations for the trading activity. The authors believe the trades were made by someone familiar with Hamas's secrets, and the potential profits identified so far may be just the tip of the iceberg.
Investors potentially linked to Hamas may have profited from bets against Israeli securities in the weeks leading up to the Oct. 7 attacks, according to a report by law professors. The report highlights suspicious trading activity, including risky short-selling of Israeli stocks and options. One trader reportedly made a nearly $900 million profit by shorting shares in Israel's largest bank. The researchers found a sharp increase in short-selling just before the attacks, suggesting it was unlikely to be random chance. It remains unclear if the profits were used to fund the terrorist group.
Unusual trading activity in the S&P 500 outside regular market hours is influencing the fate of stock options worth trillions of dollars, according to new research. A monthly pattern has been observed where key prices jump just before the expiration of derivatives tied to the benchmark US gauge, impacting which contracts will pay out. This phenomenon is generating approximately $3.8 billion in annual profits for bullish investors, raising concerns of manipulation.
Unusual trading activity in the S&P 500 outside regular market hours is influencing the fate of stock options with a face value of trillions of dollars, according to new research. A monthly pattern sees key prices jump just before the expiration of derivatives tied to the benchmark US gauge, generating profits of roughly $3.8 billion per year for bullishly positioned investors. The authors of the study speculate that "manipulators" could be at work, taking advantage of a window of thin trading to push up the index and benefit their option positions. However, it is debatable whether this constitutes manipulation or is simply a pricing anomaly.
