Just my 2 cents of course, But I doubt NOT/BMK's movement had anything to do with any rumor posted here. Lets face it, 99.9% of the market does not use/read Agoracom. Of the 0.1% that does read rumors posted here, doubt many people rush out to buy based on a criptic one-liner rumor from an anonymous poster in Europe(no offense HSS...love your posts)
In BMK's case, I would guess the mere mention of Voisey in relation to BMK was enough for the increase.
In NOT's case, I would strongly guess that last week was a natural recovery from the Market Makers games from The prior week where they targeted and succesfully took out all the $4.00 stop losses on the retail side.
This of course is JMHO
Cheers
