A total of 8.3 trillion US dollars in options are about to expire! The largest "quadruple witching day" in history coincides with pension fund rebalancing, and the US stock market faces a systemic position reset.

Scott Rubino, head of stock and stock derivative strategy at Citadel Securities, said that the US stock market is currently facing one of the most critical technical positioning adjustment windows of the year. In the next two weeks, market trends will be more driven by trading mechanisms rather than fundamental factors. The first major technical event - the June "quadruple witching day" is approaching. The current volume of outstanding options contracts has reached a historic high, with 28% of all listed options set to expire on that day, making it the largest options expiration event in history. Approximately $8.3 trillion in US options exposure will be concentrated for unwinding, 18% higher than the previous record set in December 7.1 trillion. Such a large-scale options expiration will release a significant amount of gamma exposure, triggering a systematic reset of market positions. The second major technical event - end-of-quarter rebalancing is imminent. Rubino pointed out that many pension funds highly prioritize asset allocation rebalancing at the end of the quarter. Currently, the funding ratio of the top 100 US pension funds is as high as 110%, the highest level since 2001. Therefore, "we expect a large number of plans to continue implementing de-gliding and portfolio immunization strategies, leading to mechanical selling of stocks and buying of fixed income at the end of the month," he analyzed. July 1 will mark the start of a new allocation cycle. Retirement contributions, target date funds, passive index allocations, and quant strategies will begin deploying new capital. Rubino believes that any market weakness triggered by this should be viewed from a technical perspective and is likely to be temporary. Passive fund inflows continue to be astonishing. Rubino added that ETFs have attracted over $1 trillion in net inflows since the beginning of the year, about 45% higher than the record pace for the same period last year. As a reference, the average annual inflow of ETFs in 2024 was about $490 billion - this means that the amount of funds allocated by ETF investors in less than six months is over twice the historical annual average. According to Rubino's data, in the current S&P 500 index, about 18 cents of every dollar flows to semiconductor companies; 33 cents to the Tech Magnificent 7; and nearly 40 cents are highly concentrated in the top ten index weight stocks.
