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 electronics manufacturer Kimball International Inc (NASDAQ:KBAL) jumped 13% today after announcing earnings.

So what: Fiscal-second-quarter revenue was up 9%, to $320.3 million, and net income rose 121%, to $9.2 million, or $0.24 per share. Analysts and investors were only expecting $0.20 per share in earnings, so that's why the stock is up today. 

Now what: Electronics drove sales growth by jumping 10%, but it was furniture where most of the income growth came from. That segment's net income nearly tripled to $4.46 million in the quarter. While there's a lot of excitement today, I still think the stock is expensive at 19 times forward estimates, so I'll sit out the move today.
