(I wrote this on Friday but forgot to send it! - other things on my mind)
Disgraceful manipulation!
The EDSP process run by LSE is now an 'auction' for a couple of minutes at about 10:15am
The outcome was the result of a few big hitters moving the market to suit their positions which they wanted to rollover.
(those doubters that scoff at this, look at the trades for BP and VOD etc at that time)
The trades were real and moved the underlying with the consequent effect on the future.
They had to hold it for about 2mins
I was short 5075 calls which were all set to expire around zero. Suddenly they have 63p intrinsic
That's £630 loss per contract - Ouch!
I can't see how you can have a sensible cash management policy for an event like this other than buying back the positions somewhat in advance.
I can't see that it will be possible to do this ever again on expiry day though.
For those who are fairly new to this, a warning.
The idea that out of the money options expire to zero on expiry day as expounded by most textbook theory is now dead in the water.
It may have a further profound effect on the market which has already changed in character since the introduction of the auction
Its back to the drawing board for me having been very comfortable for a few years
I think the FSA should be investigating why Liffe/Euronext failed to conduct an orderly market but whilst a few questions may be asked nothing will be done.
The dogs are eating dogs.

An update
There were some huge trades 1.6Bn shares in BP during the auction for example
Apparently the FSA is in discussion with LSE and LIFFE
The trades are being investigated
Of course the trader will say that they placed the trade at that time to take advantage of increased liquidity
If they find evidence to the contrary and fine them, that would open the way for a class action against the culprit.
Either way the basis of the settlement will change
There is also a meeting of APCIMS derivatives committee on Monday (I spoke to a member)
If nothing is done by FSA (cynically, why should they bite a hand that feeds) They may come out and simply advise private clients not to participate in this market
