I was mulling over that exact trade, but figured the relatively small amount of AMZN I had didn't justify getting off my tush. Sold a couple hours ago with a solid 60% up in 10 months (usd -> usd) and 41% in CAD terms. I'm fairly bullish on AAPL, but I already own 200 shares (selling medium term call options, hence the 100s multiple) so buying some more probably isn't worth it. Just going to keep it in cash until I see something.
Do you have any experience in hedging your US investments by shorting the USD? I'm wondering if the additional fees are worth it.
As a Canadian, the whole currency conversion thing adds another source of risk.
