2 stock charts comparing Nortel with Alcatel-Lucent and Research in Motion using Yahoo finance. See how Nortel never recovered from the dot-com bust.
Look at the similar movements over the late 90s, dot-com boom and bust. Then in 2003 watch Nortel's fall as the accounting scandal unfolded after October 2003. Except for one spike at 2004 end, the stock has been going down.
Also note how ALU has picked up in the last 5 months or so. Nortel is obviously just there for being there.
RIM is obviously a different product company so we cannot compare it directly to Nortel or Alcatel-Lucent. But as the mobile subscriber base has increased, RIM has picked up. There is a similar "W" shape in the 2008-2009 timeframe.
