... I believe there are strong bids around the 13640 mark, which is keeping downside limited.
There is apparently also an option barrier at 13725, so I must assume that it is going to be kept in a narrow range today for option expiry purposes.
Dunno what time or what exchange we are talking about here though! If the fed does something unexpected, I can't see this range holding.
13590 (mid range) as I write this....
