Nvidia premarket shares turn negative after earlier 2% gain

A premarket swing of this kind is less a verdict on Nvidia than a reminder of how thin and headline-driven off-hours liquidity can be, where a brief extension of gains can reverse without any disclosed catalyst. With no further details available, the move carries little informational weight about fundamentals and more about positioning into the open. What's worth watching is whether the reversal holds once regular trading begins, since premarket direction often fails to carry through.
