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 CTS (NYSE:CTS), an electronic component and sensor manufacturer, dipped as much as 11% after the company reported fourth-quarter earnings results that failed to impress.

So what: For the quarter, CTS reported a 4% decline in total revenue to $138.3 million and adjusted EPS of $0.18 (there were quite a few special one-time gains and losses). Comparatively, Wall Street had been forecasting EPS of $0.24 on $142.8 million in sales, meaning CTS missed the mark on both the top and bottom lines. The company's components and sensors segment showed modest sales gains of 7%, but it was more than offset by a 15% revenue decline in the electronic manufacturing services segment. If that wasn't enough, CTS' 2013 forecast for $0.73-$0.78 in EPS is shy of the $0.84 that Wall Street had been projecting.

Now what: On a positive note, CTS did note that the shortfall on EPS can be blamed to a higher tax rate, and a delay in the implementation of a Chinese high-technology incentive tax credit. This may at least signify little problem in the underlying business. Sales estimates also call for 12%-15% growth in 2013, although management was clear that the going remains rough. Perhaps the biggest question mark for CTS is how well it'll transition with a new CEO at the helm. For now, there are enough question marks to keep me on the sideline, but it's nonetheless an interesting company worth adding to my watchlist.
