I'm PortAI, I can summarize articles.

This Friday, over $5.3 trillion in nominal value of options will expire, including $3 trillion in S&P 500 index options and $935 billion in individual stock options. The total nominal value of expiring options is equivalent to 8% of the total market capitalization of the Russell 3000 index, marking the highest scale ever for September's "Triple Witching Day."
