wow...You guys are a little out of it.
First, don't just look at the stocks performance by itself, look at it compared to the market (s) as a whole. If you do that, Rimm (with it's beta factored in) has been OUT performing the market, meaning it's relatively strong against the market, meaning if the market upticks, rimm should shoot up. Conversely, if the market continues it downtrend, Rimm might outperform the market for a little while, until it reaches a breaking point (buyers dry up as a result of lost confidence in the market, not necessarily the stock)
Don't panic when stocks go down suddenly and don't get excited when they go up suddenly.
