RE:Short Interest sees an increase at NYSEShort interest reports are helpful but are not actually up to the minute updates. The A report is disseminated around the 15 th of each month but actually covers the period of the previous end of month settlement date, while the B report covers the period of the month from day 1 settlement day to the 15 day of settlement. Thus there is a 2 week lag time before it reaches the public. In that 2 week period there may be changes that are not being reflected on the trend. It doesn't tell us if shorters are covering or increasing their short positions.
