I trying to remember what happened and I can't remember the events, but -- Didn't NevWest own Computer Clearing Services? And someone just recently purchased Computer Clearing Services when NevWest went belly up? ******************************************************** AND -- to answer your question with a question -- Re: Could it be because Penson Financial is actually Computer Clearing Services? Was someone shorting CMKM? And covering the short position with a certificate? (lol -- keep going, I have a few more questions :-) )
