Read full description

CrocoSight is a calm valuation watchlist designed for long-term investors. It shows one thing clearly: where a company’s current PE, PB, and PS stand in their historical percentiles. Follow stocks across the US, HK, and CN markets in a clean watchlist built for low-frequency review, not constant monitoring. Search for businesses, compare their valuation percentiles at a glance, and dive into long-term historical trends. CrocoSight intentionally strips away price charts, news headlines, social chatter, and frantic market alerts. Instead, it offers a quiet, reliable way to judge valuations. It is built for investors who already know what they want to own and are simply waiting for the right margin of safety. CrocoSight is free to use, with an optional subscription for higher capacity and broader reminder access. The app also supports configurable valuation reminders and local notifications for tracked stocks. Notice: CrocoSight does not provide investment advice, recommendations, or predictions.
