Today is a quadruple witching – which is the simultaneous expiration of 4 sets of options…..Stock Index futures, Stock Index Options, Single stock options and single stock futures…it happens 4 times a year (qtr end) and is usually associated with much bigger volumes and volatility…..Look for extremely large volumes on both the openings and closings and while it looks ‘big and scary’ the fact is that in the final mins leading up to both bells – the stocks all pair off right where they are supposed to. You see – it is not a secret – traders expect it, and the mkt is well positioned to manage it.
