Amkor Technology Shares Plunged: What You Need to Know

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: Semiconductor packaging and testing expert Amkor Technology (Nasdaq: AMKR  ) crashed overnight, falling as much as 13.5% in early trading today.

So what: The third-quarter report fell short of analyst expectations and near-term guidance was also disappointing. A low-end product mix and slow sales to consumer electronics customers conspired to set up this weak report.

Now what: We've heard this song before: A company involved in the manufacturing process of semiconductors unveils a slow fourth-quarter outlook but gazes ahead to a generally strong market in 2011, and the shares take a pummeling. Nanometrics (Nasdaq: NANO  ) did it, Mattson Technology (Nasdaq: MTSN  ) too, and FSI International (Nasdaq: FSII  ) wasn't safe either. It seems you can take your pick among chip-fabrication experts if you're looking for a high-tech stock that's been oversold on recent short-term concerns.
