re: SLB options 'net change'

The bid is 10 1/4, ask is 11 on the Jan 2000's. The 'change' is based
on the last trade which is 10 i.e. the options upticked after the
last trade. Usually best to monitor change-in-bid/ask rather than
change-in-last-price with volumes like these.

Bid Ask Last Vol
6 6 1/2 Jan 99 5 7/8 10
10 1/4 11 Jan 00 10 26
14 1/8 14 7/8 Jan 01 14 1/2 3

Unfortunately, I don't know of a source for the bid/ask as of end of
Thursday so we don't know if the price used to determine the net
change was inside or outside the then current bid/ask. The
year-to-year changes in bid/asks don't appear unreasonable.
