Understand sell, then cover but rising market First, thank you for the information. :-) >> Completely understand to sell then cover, but in rising market, the volumes were not this extreme. >> The float is held tightly >> Easily borrow shares in-house or from another MM >> Especially, notorious shorting from overseas markets >> Seen it a number of times >> They deliver shares, but from someone's inventory Granted, I may be wrong on the total volume short, but it's gotta be at least 50M+. There is no other way to explain it. I've watched this stock daily and volume was just not there to cover daily on selling then buying back. http://bigcharts.marketwatch.com/quickchart/quickchart.asp?symb=uoip&insttype=&freq=1&show=&time=7 If pick a historical day when trading b/t .002-.005, they were doing this consistently. Caught in rising market! http://regsho.finra.org/regsho-Index.html JMO, Scruffer P.S. Justified my rational is second link of original post. It's the MM's SOP, "Standard Operating Procedure".
