RE:Heads up on us stock bomberBDRBF (USA OTC symbol) is actually shares of BBD.B, priced almost always at the TSX price with the current exchange rate applied. Rarely, it will deviate by a penny or two temporarily if a large enough sell or buy takes place.
People who buy the over the counter share BDRBF in USD and who then sell it for USD make more money if CAD is stronger when they sell. This is a good reason for US and EU citizens to buy now as CAD is weak and in 2-3 years it might strengthen. When the CAD gets 15% stronger, the USD price of BDRBF rises by 15%.
This cannot work for Canadians who start with CAD and want CAD back when they sell, they will only lose the exchange fee twice, once when they buy and once when they sell.
