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 office equipment maker Herman Miller (Nasdaq: MLHR) had investors falling out of their chairs this morning after jumping as much as 13% in trading.

So what: The company ended fiscal 2011 at the end of May and didn't disappoint investors with its spring performance. Sales were up 37% to $441.5 million, and earnings per share jumped to $0.30 after breaking even last year. Analysts expected $418 million in revenue and EPS of $0.26.

Now what: The job market may be bad, but North American business customers are updating their offices by ordering 21.4% more product than last year. For the year, earnings were up nearly 150%, and management expects momentum to continue next year. Shares aren't cheap at 24 times 2011 earnings, so I'm not an eager buyer here, but if there's a pullback the company's improving sales are encouraging.
