Rocket Lab Shares Plummet 7.98% on $1.52 Billion Trading Volume Ranking 54th in Market Activity

Rocket Lab (RKLB) closed at a 7.98% decline on Sept. 24, 2025, with a trading volume of $1.52 billion, marking a 22.32% drop from the previous day. The stock ranked 54th in market activity for the session amid mixed sector performance.

Recent developments highlight investor caution around the company’s near-term outlook. A technical analysis report noted elevated short-term volatility but emphasized the absence of new fundamental catalysts. Market participants are closely monitoring execution risks following a series of delayed project timelines reported earlier this quarter.

Back-test parameters require clarification to generate actionable insights: 1. Define the equity universe (e.g., NYSE/NASDAQ) 2. Specify weighting methodology for the S&P 500 constituents 3. Confirm trade price conventions (close-to-close or open-to-open) Once these parameters are finalized, a performance evaluation from January 3, 2022, to the present can be executed to assess historical effectiveness.

To run this back-test for you I need to pin down a couple of practical details: 1. Market universe • Do you want the whole U.S. equity universe (NYSE + NASDAQ) or a different market/exchange set? 2. Weighting on the 500 names • Equal-weight each name for the one-day hold, or weight by volume / market-cap? 3. Trade price convention • Enter at today’s close and exit at tomorrow’s close (most common for a daily re-balance), or use open–open prices instead? Once these are fixed I can generate the day-by-day trading signals and run the back-test from 2022-01-03 (first trading day of 2022) to the present.
