Just came across something pretty interesting about how stock markets might be shifting. Nasdaq is apparently gearing up to pitch the SEC on extending trading hours way beyond what we're used to. So right now stocks trade five days a week for about 16 hours daily, but they're looking to move to a 5x23 model that's basically 23 hours a day, five days a week.

The way it would work is pretty clever actually. You'd have your standard daytime session running from 4 a.m. to 8 p.m. Eastern Time, with the regular market hours still 9:30 a.m. to 4 p.m. Then there's this whole new nighttime session from 9 p.m. to 4 a.m. the next day. So with this 5x23 schedule, the trading week would kick off Sunday at 9 p.m. and wrap up Friday evening at 8 p.m.

What caught my attention is how this 5x23 framework would essentially create continuous market access for traders. The trades happening between 9 p.m. and midnight would technically count toward the next calendar day, which is an interesting way to handle the overnight transition.

I think this is worth paying attention to because if this actually gets approved, it could reshape how traditional markets operate. The 5x23 model would be a massive shift from the current structure. It's the kind of market infrastructure change that doesn't happen often, so definitely keeping an eye on whether the SEC greenlight this proposal.
