Liu Liang Chiu-Chu Sara's 532-transaction Form 4 file for Super Micro Computer (SMCI) runs on the same calendar as Charles Liang's recent activity and produces strikingly similar line items: the May 26, 2026 340,000-share Code G gift, the November 26, 2025 5,000-share gift, the February 17, 2026 7,300-share exercise cycle. Her historical file — 4,859,418 shares sold against zero buys — mirrors Charles Liang's sell-side aggregate almost exactly, a coincidence that suggests shared compensation or tax-planning origins rather than independent portfolio construction. The right read: her file is not a portfolio; it is a calendar, and the recent 340,000-share gift is the annualized charitable or family-trust distribution timed to the same date as the adjacent SMCI filing. For calendar-based watchlists, this is the kind of duplicate-event pattern that produces two flags for what may be a single underlying decision, which inflates the apparent event volume without adding informational content. The real signal worth tracking is whether both insiders' exercise cycles continue at the same cadence — if one exhausts tranches before the other, the calendar will drift apart and the recent synchronization will end, which is itself a watchlist signal that the underlying compensation plan has changed.
