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 network equipment provider Ixia (Nasdaq: XXIA) rose nearly 11% in early trading before closing up 7.7% on positive analyst comments.

So what: Ixia and a handful of peers rallied when Piper Jaffray issued a note saying JDS Uniphase (Nasdaq: JDSU) could report surprisingly good fiscal second quarter results, Bloomberg reported. The implication? Earlier flooding in Thailand hasn't had as much of an impact as first expected.

Now what: Other peer group winners included Aeroflex Holding (NYSE: ARX), up 9%, and Juniper Networks (Nasdaq: JNPR), up 5%. Ixia outperformed both, but it's also the cheapest of the three when you factor in expected growth. Does it matter? Which of these networking stocks would you buy, if any?
