Apple vs PSN Buying US dollar stocks require foreign exchange conversion in and out and can cost 4% or more round trip. The US dollar could also drop another 1%. Of course there are also tax consideration unless held in your RRSP or TFSA.
PSN could announce results of their new product tests. If water re-cycling becomes a reality the stock could take off big time. There is a huge short position overhanging the market. If it takes off they better cover and could push the stock higher very quickly. That is the biggest risk that I see.
