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 electronic security specialist Checkpoint Systems (NYSE: CKP) rose more than 11% in early trading on higher volume after adjusted third-quarter results beat estimates by $0.09 a share. The gains evaporated and turned into a 1.7% loss when management said it would expand its current restructuring plan.

So what: In a statement, CEO Rob van der Merwe cited "global economic uncertainty" and "unpredictable retailer behavior" in announcing plans to strip another $58 million from operating costs. Checkpoint's radio-frequency technology is typically sold to retailers for tracking merchandise.

Now what: Kudos to van der Merwe for taking action, but investors shouldn't applaud too much, or too loudly. Restructuring already cost $17 million in the current quarter. No one knows when those cuts -- or the cuts to come -- will allow Checkpoint to return to growth. What's your take? Would you buy shares of Checkpoint Systems at current prices?
