Changes in reported position value vs the prior 13F, so price moves count too, not just shares bought or sold.

GAINLINE FINANCIAL PARTNERS, LLC Holdings (2026-09-30)

Rows tagged Call or Put are options positions, not stock. Per SEC Form 13F-HR, Value shows the notional value of the underlying (shares covered × underlying price), not the option premium. Shares is the number of underlying shares covered (divide by 100 for contract count).
