S&P 500 futures fall 0.6%, Nasdaq futures drop 0.8%

The absence of a stated catalyst is itself the notable feature here: index futures moved without an identified driver, which makes the move harder to attribute to any single macro or sector event. The Nasdaq underperforming the S&P 500 by a wider margin is the only directional signal in the item, hinting that growth-heavy exposure is carrying the larger share of the pre-market weakness. Whether that gap persists into the cash session, or narrows once a driver becomes apparent, is the open question worth tracking.
