Taiwanese IC substrate maker Unimicron dropped sharply after investigators searched the company, and shareholders are bracing for more pain when trading resumes Monday.

• Prosecutors raided Unimicron over suspected relabeling of China-made substrates, faking the country of origin, and insider trading.
• The stock fell hard on Friday, giving up more than 10% from its intraday high before closing off the lows.
• Small investors are panicking online, with many who bought near the top wondering if they can get out before sell orders pile up.
• Others see the drop as a buying chance and say they would add more if the price keeps falling, arguing the business itself is still sound.

Outlook: Monday's open is the test — whether bargain hunters step in fast enough to stop the slide or selling pressure carries it lower.
