RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:RE:Air Canada Number 1 - For percent of float short in your example the shorting on the first day would show as 50% short vol for the day and a net increase in the short position (up 500 k) and on the second day there would be a net reduction of 500k to the short position and zero % as the daily % short vol...this was straight forward to me...my only uncertainty was in whether the daily short vol included covering short as well or not...thanks all for contributing...glta
