币界网报道:Strategy has expanded its bitcoin accumulation funding through perpetual preferred shares, with TD Cowen initiating "buy" ratings for STRF ($126 target), STRK ($140), and STRD ($112). These shares offer fixed dividends (8-10%) with varying convertibility terms, alongside Strategy's existing $84 billion "42/42" capital raise plan. The firm holds 600,000 BTC ($64B) and aims to reach 850,000 BTC (4% of supply) by 2027. TD Cowen notes Strategy’s 63% NAV premium is justified as equity sales directly boost BTC-per-share holdings.
