I have been trading INFN and done well, today I bought INFN and CIEN, again for a trade.  I think that while CIEN is guiding lower on revenue range for next quarter, the punishment seems too harsh.  I too think that CIEN's CEO would be lowering the bar substantially to make the next quarter easily, with a ~20% drop today, I think there is a good chance for a decent bounce, more so considering that at current levels the PE is below 10, which, even if estimates are rachetted down, would still look on the low side relative to the general market multiples. And certainly feel the same way about INFN, the guilty by association is not justified.
