Sector-Wide Insider Alpha
Analyzing insider movements across the Electronic Computers sector provides a macro-view of executive conviction. When multiple leaders in different companies within the same SIC code (3571) simultaneously buy shares, it often indicates an industry-wide undervaluation or a positive shift in market cycles.
SEC Filings in Electronic Computers
Every transaction in the Electronic Computers 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.
