Finisar Shares Popped: What You Need to Know

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 Finisar (NAS: FNSR) rallied close to 17% before closing up 14.5%, riding on the coattails of Cisco's (NAS: CSCO) strong earnings report.

So what: Several optical-networking stocks rose. JDS Uniphase (NAS: JDSU) and Ciena (NAS: CIEN) each soared about as much as Finisar, presumably on the idea that a resurgent Cisco is reflective of industrywide demand for fast data delivery gear.

Now what: Finisar could benefit more than most as a supplier for Cisco's own branded optical-networking equipment. There's no guarantee, of course; but I get the reasoning behind the rally. Do you agree? Disagree? Weigh in using the comments box below.
