Standard Industrial Classification: SIC 3672
Industry Insider Sentiment Analysis
The Printed Circuit Boards sector (SIC 3672) acts as a critical barometer for broader economic health. Our real-time monitoring reveals total transactions. Monitoring "cluster buying" is one of the most reliable leading indicators for future sector performance. By analyzing aggregate data across this specific Standard Industrial Classification, investors can filter out individual company volatility and identify high-conviction trends. When multiple directors and officers within the same industry move capital simultaneously, it often signals an upcoming sector-wide revaluation or a fundamental shift in supply chain dynamics that has yet to be recognized by the broader public market.

Sector-Wide Insider Alpha

When multiple leaders in different companies within the same SIC code (3672) simultaneously buy shares, it often indicates an industry-wide undervaluation or a positive shift in market cycles.
SEC Filings in Printed Circuit Boards
Every transaction in the Printed Circuit Boards industry is reported via Form 4 disclosures. By filtering these filings by industry, investors can detect institutional-scale sentiment shifts before they are reflected in broader market indices, following the capital flow of those with intimate industry knowledge.
UNDERSTANDING THE DATA
FILING DATE: The date and time when the transaction was reported to the SEC. This is when the public first receives the information.
TRADE DATE: The actual day the insider executed the purchase or sale in the market.
INDUSTRY: The specific market sector the company operates in. Useful for identifying broader institutional capital flows across sectors.
OWNED AFTER: The total number of shares held by the insider following the transaction. This highlights the insider's remaining conviction in the company.
CHANGE %: The percentage increase or decrease of the insider's total position. Large percentage changes often carry more weight than the dollar amount alone.
