BLDP Friday Massive Volume on the TSX...14M + shares.The average daily vol is less than 1M
I am assuming it has to do with Ballard's S&P / TSX Index deletion, (which is in effect @ Sept 23)
And all the Index ETF'S required to get rid of BLDP,... and most did close to the end of the day
And that overhang would explain recent weakness, since the deletion was announced ?
