The majority of expiring options follow that. The more illiquid and volatile the stock is, the less relevant the close is. Take GE vs PCLN. GE is around 27 and PLCN is around 1183. If GE closed at 27.01, the risk of not covering a hedge or cover is low over the weekend. For a position in PLCN, would you care about a few cents? If you had a spread on or stock vs your options, you would do what is right for your position. You would try to close or roll toward the end of the day but sometimes you can get it off or the stock moves a lot near the close.
Does that help?
Yes, absolutely. Very informative. Thank you Robert!
You just got bamboozled. No way does that post (#9) make sense to you, it sure doesn't to me.
