Passive stake amendment
Actionable Insight • Neutral

Berkshire's continued large passive stake in Lennar signals long-term conviction in the homebuilding sector. Monitor for any future conversion to a 13D filing, which would indicate activist intent, but the current filing explicitly maintains passive status.
