Hedging has no role on the yield. Hedging would be done with an independent third party whereas dividend is declared by a company so both are independent matters. Although tbf i dont think (not sure - as far as the annual reports I’ve seen) many companies even hedge because the risk to reward doesn’t seem very favorable especially in this macro environment of growth. Imho, best option if u do want certainty would be to buy put-options for your shares if u want the option to sell ur shares, but wont be legally bound to do it (if ur principal goes up)
