The CEO's sustained selling over the past month, including this new Form 144, is a strong negative signal. Despite bullish analyst consensus, the insider's consistent unloading of shares suggests a lack of confidence in near-term valuation or upcoming catalysts. Traders should monitor for any negative news or guidance changes and consider reducing positions or hedging.
