Contract maturities | Weekly statement September 19

Contract expirations on Friday totaling $3.2 Trillion known as the "day of "Triple Witching.

(Triple Witching is a concept that refers to the simultaneous expirations of stock options, index futures and index options contracts all on the same trading day. This happens four times a year: on the third Friday of March, June, September and December).

Anticipating the event, S&P futures fell 0.8% on Friday morning, returning to a 2-month low, while the Nasdaq 100 lost more than 1%, Europe marked a fourth day of losses, and Asia was a sea of red led by China.

This tends to be regular behavior for multiple maturity days, but it is more important what happens afterwards, as volatility in the market generally increases after these types of stock market events.

Another very important event of the week was the release of the Consumer Price Index data, which in the last 12 months increased 8.3%.
