>>MB,
Been trying to figure the rhyme and reason of the price movements of options,
here goes:
Have been holding NVLS puts (NLQOH)Mar 40's
On 12/16 NVLS drops 3 7/8

MAR 40 (NLQOH) bid-2 7/8 ask-3 1/4 last-1 13/16 chg-0

On 12/17 NVLS goes up 3/4

MAR 40 (NLQOH) bid-2.5 ask-2.875 last-2.5 chg-+0.687


So, on the 16th the stock drops almost 4 however the Mar40's don't move.
Then on the 17th the stock pops up 3/4, the 45's & 50's don't move,
however the 40's move up 5/8's.???????<<

bill, options often don't trade as frequently as stocks and their swings are greatly exaggerated (read, the last trade can be real old and much different from the current bid/ask). the bid on the 16th was $2 7/8. it dropped $0 3/8 to $2.50 on the 17th when the stock went up. the $1 7/8s was a trade that happened long, long ago in galaxy far, far away. it could have occured several days or even weeks ago.

hope this helps.

Bill, simple. In illiquid options, the type I prefer, one buyer or seller can hit either the bid or the offer for a price change. The fact is, the Market Makers don't carefully update their prices on these options.
