Our take

3 rules fired on IRON

In short: none of these rules has solid or some evidence yet, so they show no clear lean on IRON.

How each did in past tests, against similar stocks over 3 months. Past results don't predict future ones.

The 0–100 score for IRON, and which of these rules are open on it right now
Members see one number for how strongly these rules agree on IRON, and the day each rule fired. Better-tested rules count more, and so do different kinds of filings that point the same way.

How to read this comparison

The median is the middle count in up to 12 earlier, non-overlapping 28-day periods; the range runs from the smallest to the largest count. The latest period is excluded from both. A comparison needs at least 6 earlier periods, including 3 with activity. The feed’s latest disclosure must be within 7 days of the current period’s end. This freshness check does not verify complete collection.

Insiders include individuals and reporting entities; only purchase and sale codes enter this view. Congress counts reporting members, including their disclosed family transactions. The same filer can appear in purchases and sales, so these categories should not be added into a net count.

These are stored disclosures, not a complete measure of trading. Reporting delays and collection gaps can change the comparison. More activity does not identify a motive or predict a stock’s return.
