Michael B. Luu: trading record in brief
Michael B. Luu is a declared insider of California Water Service Group (senior executive), with filings sourced from SEC (Form 4). We count 49 filings; the first trade dates from 4 January 2016 and the latest from 5 September 2026.

The newest entry dates from 8 September 2026: a share grant of €3,014, in California Water Service Group. The median gap between a trade and its publication by SEC (Form 4) is 3 days. The legal deadline for a Form 4 is two business days after the transaction. Sales are harder to read than purchases, since they often meet personal needs such as tax or diversification. Every figure here comes from the filings published by SEC (Form 4) and describes the past, not future prices; it is not investment advice.
