For a brief moment this week, it looked as though Apple’s (NASDAQ: AAPL) shares were going to become reacquainted with gravity. With connection rates for its iPhone below expectations, would Research in Motion (NASDAQ: RIMM; TSX: T.RIM), the maker of the BlackBerry portable email device, make headway in the market? Opinion was divided (http://www.stockhouse.ca/shfn/article.asp?edtID=20000), as Sean Mason learned.

The U.S. dollar veered dangerously close to the 80-cent level before trading higher. Donald Dony examined the prospects for a 70-something cent dollar (http://www.stockhouse.ca/shfn/article.asp?edtID=19993 ) and read the tea leaves for commodities and other currencies should this drop occur.

While some investors were breaking out the champagne and cigars as the Dow topped 14,000 last week, others were setting stop losses and taking other measures to preserve their investment capitol (http://www.stockhouse.ca/shfn/article.asp?edtID=20006 ).
