Although we don't believe in timing the market or panicking over market movements, we do like to keep an eye on big changes -- just in case they're material to our investing thesis.
What: Shares of Tellabs
So what: Tellabs, which competes with the likes of Alcatel-Lucent
Now what: Rarely will you find me siding with the mouth foamers, but in the case of Tellabs I see good reasons for today's selling. Telecom equipment is a sensitive business that depends on the largesse of carriers fighting for a big bucket of low-margin profits. If Tellabs can't make good now -- in the golden age of smartphones, tablets, and IP telephony -- why should anyone believe it will make good when these high-growth markets mature?
