Referenced filing footnotes
This Form 4 amendment is being filed to correct the nature of ownership that was inadvertently reported as being directly owned in the prior Form 4. The reporting person and his spouse are co-trustees of the trust.
Method and limitations
Daily-close v1: split-adjusted SIP daily bars supply purchase-date closes and all exit closes for both stock and SPY. Disclosure entries use each symbol's first regular-session minute open strictly after SEC acceptance + five minutes; acceptance is a publication proxy. Entry is session zero; exits occur at i+h. Daily bars are used only after the New York calendar day has ended, with a 15-minute data delay. Prices are vendor aggregates, not guaranteed fills or universally identical to official auction prices. Excludes dividends, fees and slippage. Related transaction rows are not independent signals.
Run cutoff: 2026-11-04T12:55:26.004Z. SEC acceptance: 2026-09-21T20:31:01.000Z.
Discretionary intent remains uncertain unless supported by the filing. Unresolved amendments and security identities are not silently treated as eligible trades.
