Well all you said is fine and your opinion but it does not answer the question OP had which I think is a valid question. Nothing happened, it's the spread, "stupid". 

If only. More like typical for a low volume stock such as this one. Sh.. happens.
Today for instance 9:31:04 Ask $49.27, 9:31:06 Bid $49.00, Ask 9:31:08 $49.26
Spread didn't narrow to under $0.10 well after 10:00 am
So I believe myself and others already DID answer the question correctly. And that answer is low volume stocks act erratically. Find bigger fish. Or waste time trying to figure out "why did it do that".
