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 Jabil Circuit (NYSE: JBL) cruised 12% higher today after earnings topped expectations.

So what: Core earnings per share were $0.54, three cents higher than estimates, and revenue of $3.93 billion was more than the $3.91 billion analysts expected. To top it off, the fiscal-third-quarter revenue estimate of $4.1 billion to $4.2 billion and earnings per share estimate of $0.55 to $0.59 both topped estimates.

Now what: That's what I call an earnings trifecta beating on revenue, earnings, and outlook. The Japan disaster seems to have avoided Jabil Circuit facilities and disruptions should be relatively minimal going forward. Even after today's jump the stock is down slightly in March, and market fears about Japan interruptions seem to be easing, so I think there's a lot of upside potential for shares.
