Northrop Grumman Stock Plunges 1.81% as Volume Slumps to 309th in U.S. Rankings

On October 10, 2025, Northrop Grumman (NOC) closed with a 1.81% decline, marking its lowest intraday level since early September. The stock traded with a volume of $410 million, a 35.49% drop from the previous day’s activity, ranking it 309th in trading volume among U.S. equities. This underperformance came amid broader sector volatility, with defense contractors facing mixed sentiment as investors recalibrated positions ahead of key earnings reports and fiscal policy updates in the coming weeks.

The sell-off appears tied to strategic rebalancing by institutional investors, with no immediate catalysts emerging from regulatory filings or earnings surprises. Analysts noted that the sharp volume contraction suggests reduced short-term liquidity, potentially amplifying near-term price fluctuations. While the company’s long-term fundamentals remain intact, the recent dip reflects broader market caution in the defense sector, where valuation multiples are being re-evaluated against shifting geopolitical risk assessments.

To run this back-test I need to clarify a few practical details so the set-up matches exactly what you have in mind: 1. Universe • Which market or exchange should the “top-500 by volume” be drawn from (e.g. all U.S. listed common stocks, a specific exchange such as NYSE + NASDAQ, or another region)? 2. Weighting method • Should the 500 names be held equally-weighted each day (the most common choice for this type of study)? 3. Execution price • Do we enter at the same day’s close and exit at the next day’s close, or enter at next day’s open and exit at the next day’s close? (If you don’t have a preference I’ll default to “buy today at the close, sell tomorrow at the close.”) 4. Cash/benchmark • Should leftover cash (if any) earn zero, or be ignored (equal-weight automatically consumes all capital, so this is only relevant if you prefer value-weighting)? Once I have these points confirmed I can generate the daily selection set, run the back-test from 2022-01-01 through today, and show you the performance metrics and chart.
