Insider Trading

Pulls insider trading data from Yahoo Finance's SEC Form 4 filings and gives you a quick read on whether executives are buying or selling. You can check a single stock or compare multiple tickers at once, and it ranks results by net buying activity so the most bullish insider sentiment floats to the top. The summary breaks down buy versus sell counts and dollar values, which is helpful when you're trying to gauge conviction from the people who actually run the company. Default lookback is 90 days but you can adjust it. Straightforward tool for when someone asks if insiders are accumulating or dumping shares.
