RE:TD Now?TD is a major player in most Canadian names...I guess their name being Toronto Diminion would help explain why?. If you haven't already, take a look at the regulator's website: https://www.iiroc.ca/sections/markets/reports-statistics-and-other-information/short-sale-trading-statistics-and-reports . I'm not sure why brokers are given the opportunity/ability to hide behind the "Anon" label/tag. At the end of each month they're required to diclose a breakdown of which brokers used it. Often times there will be a large % of volume related to short selling activity but the net short position will barely change. This makes me wonder if high frequency traders or prop desks may be manipulating/profiting from other investors/traders' activities. May not be as much of an issue for CUB but you never know.
