What can be sourced

The record shows open-market insider buying on file within the last 90 days.

None of that is proof of causation. A filing or a target change that lands near a move is context, and the market routinely moves on neither.

What it does do is separate a move with something behind it from one with nothing.

What insiders have been doing

3 open-market insider transactions are on file for the last 90 days.

Insider activity before a move is the one piece of context that carries money behind it rather than an opinion.

It is also disclosed late, so proximity to today's move should not be read as foreknowledge.
