Dow down 100 points with 2 to 1 negative advance/declines. Volume good. It looks like I have missed this move. Did have an order in but did not get filled. Perhaps will try and get short if there is a bounce tomorrow. Summation index is probably headed down now. Short post due to dentist. Not sure about the duration of this sell-off because we will be oversold tomorrow. Might just wait for a solid signal. We'll see...
