But you have a point that timing is key. Right now, the negative macro issues with subprime and the recent PPI/CPI's numbers (the latter of which is rear view mirror and may be a one time event) trump CIEN's fundamentals right now.
And the shorts know it and are taking full advantage right now. Broken tackle and open field run for them. Not much different than BIDU for the bulls on the way up, just the mirror opposite.
But at some point the fundamentals do matter. Last January they didn't with AAPL when it dipped into the high $70's after two back-to-back blowout Q's on earnings.
Compare CIEN's trailing growth to RIMM's. Yes, CIEN's just as good.
