The counts above are free. Who they are, and what each of them traded, is part of Pro — see what it includes.
Form 4 insider trades are exact and filed within two business days. Congressional figures are range midpoints disclosed up to 45 days after the trade, and 13F positions are a quarter-end snapshot. All three are a record of what was disclosed, not a signal.
