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 optical networking gear maker Finisar (NAS: FNSR) rose more than 14% in early trading after a Morgan Stanley analyst said in a research note that the company could take share from industry peer JDS Uniphase (NAS: JDSU) .

So what: Morgan sees the flooding in Thailand hurting JDS's business. Management confirmed as much in cutting its second-quarter revenue outlook by $35 million to $45 million. Investors ignored the weak guidance in pushing JDS shares up as much as 11%.

Now what: Of the two, Finisar is the one priced for less than the long-term earnings growth rate analysts expect. Does that make it a better buy? You tell me. Would you buy shares of Yingli Green Energy at current prices? Please weigh in using the comments box below.
