🤖 AI Activity Report

Status: very-active

AI Reasoning: I found a 13F/portfolio disclosure reporting Belfer Management LLC holdings for the report period 2025-10-28, showing recent trades/holdings including Meta (META), Sherwin-Williams (SHW) and CoreBridge Financial (CRBG). The disclosure date is within one month of the evaluation date, indicating an investment activity less than 3 months ago (about a few days to a month), which corresponds to the most active category.

Here are the thresholds established for the different statuses:
Not Active – No known investments in the last 12 months.
Low Activity – Only known investments between the last 12 and 6 months.
Active – Known investments between the last 6 and 3 months.
Very Active – Known investments in the last 3 months.
