Rocket Lab USA, Inc. (RKLB) experienced a pre-market plunge of 5.12%, indicating significant selling pressure before the regular trading session.

The sharp decline follows reports of decisive bearish sentiment among institutional traders, evidenced by large options trades. A $21.25 million short put combination and a $15.49 million long put purchase signaled a clear institutional bias towards downside risk or a lack of upside conviction. Overall bearish options flow reached $36.74 million, reflecting a negative tone and positioning that likely contributed to the pre-market sell-off.
