Glenn--

More options observations/questions. Just how, I wonder, do the market makers work? Here's something I've noticed more than once (though I've never followed it closely enough to draw any real conclusions): after the market close, but before the close of the options market, bid and ask are adjusted even if no more contracts are traded. Usually both are lowered. In the morning I see the opposite. For example, the other day when I was considering SEGFIs (just as well I didn't do it), they were supposedly asking 1 7/8 just before the options market opened (this according to my broker's info as well as my own). The stock was flat. But when I checked later in the day I saw that the contract actually opened at 2 1/8. This is especially annoying, as you don't know what you'll be paying if you put in a market order at the open.

As I said, I haven't kept track of a representative bunch of specific examples, and so I may be imagining things. Any thoughts?
