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 radio chip maker Aeroflex (NYSE: ARX) hit a patch of static today, falling as much as 19.7% on heavy, spiky trading.

So what: Aeroflex lowered its fourth-quarter sales estimates by 11% last night, immediately followed by two analyst downgrades from buy to hold. Management pinned the lower-than-expected sales on a late, final approval from the Marine Corps on a $16 million order of radio maintenance equipment.

Now what: Aeroflex is suffering from lumpy sales more than anything else. A delayed order is a far cry from a panic-inducing canceled sale, after all. I'd understand this steep drop if rivals Honeywell International (NYSE: HON) and Agilent Technologies (NYSE: A) were stealing Aeroflex's business, but that's not what's happening at all. This looks like a great time to start a position in this five-star CAPS stock with plenty of renewable government business -- I'm dipping a toe in the affordable waters myself by taking a thumbs-up position in my own All-Star CAPS portfolio.
