The past week has seen investors in Research in Motion (RIM) heading for the door with a wild look in their eyes, breathing hard with their ears pinned back. 

The share price of RIM has plummeted over 50% since the beginning of 2011; a trend that has accelerated recently because of the brickbats thrown at the new BlackBerry tablet by reviewers, the fact that no new smartphone product/update has been announced, and, a drop in earnings. 

RIM is No. 3 in the smartphone market behind Apple and the Google-platform Android platform smartphones, but that spot is looking more and more tenuous everyday as RIM continues to lose market share. Comscore says RIM’s market share in the smartphone sector has taken a massive dive from 40% in 2010 to the current 26%. And, BlackBerry sales last quarter have experienced their first quarterly drop in sales since 2005. Lastly, the market cap of RIM now sits at $14 billion USD, down from $80 billion a scant 36 months ago.
