The boxing in of share price which has been going on forever works until it doesn’t. Last week there were a couple days in a row late where short volume was over 80%; on Friday it was 84.21%. It reminds me of when I took inorganic chemistry in college…they have pH indicators like phenol red and methyl red that allow you to tell visually by color change what is happening with pH in a liquid medium. Seems like shares on the sell side are titrated to effect, like trying to control pH; any updraft is met with equal and opposite force. When the Boxer Rebellion (read: major catalyst news) hits, the people dropping just enough acid on the share price to keep it down might find their chemistry experiment blows up.
