Pros include increased accessibility for non-U.S. investors, flexibility for domestic traders, improved price discovery, and enhanced regulation. Cons include the risk that liquidity may not increase and challenges around earnings releases.
Direct beneficiaries include Cboe Global Markets (CBOE), Nasdaq (NDAQ), Intercontinental Exchange (ICE), Equinix (EQIX), Digital Realty Trust (DLR), Broadridge Financial Solutions (BR), Virtu Financial (VIRT), and potentially CME (CME).
Extended hours alone might not boost liquidity and may result in more thinly traded periods, particularly after-hours; overall, exchanges may gain from higher related activities but investors could see spottier liquidity.
