Monitor for actual sale execution and any subsequent Form 4 filings. A large block sale by a major shareholder could pressure the stock in the near term, especially given the stock's recent strong run (+77% over 20 days per historical performance). Watch for any additional insider selling or changes in MegaChips' ownership level.
