Does anyone know when QQQ's expire. Is it Thursday's close (since the NDX is a narrow based index) or is it Friday since it's a stock? Thanks. Never held options till the end and was just curious.
I believe you may be mistaken. QQQ equity options cease trading @ 3:15 P.M CT on expiration Friday. Technically, they expire @ 11:59 P.M. Chicago time on Saturday night after Friday's close of trading. NDX and MNX Index options cease trading @ 3:15 P.M CT on the last business day prior to expiration Friday (usually a Thursday). The settlement value for the NDX is a volume weighted-average for each component of the index during the first five minutes of trading after market open on Friday. This value is given by the NDS. The settlement value for the MNX options is 1/10th the value of the NDS. There are some other elements should a security not open, but I am sure you get the general picture. Metooxx, do you concur with this interpretation?
