Northrop Grumman Surges to 192nd in Dollar Volume with 33.39% Jump Shares Dip 0.09
On September 25, 2025, Northrop GrummanNOC-- (NOC) saw a trading volume of $610 million, marking a 33.39% increase from the previous day and ranking 192nd in dollar volume among U.S. equities. The stock closed with a 0.09% decline despite elevated liquidity.
Recent market activity suggests short-term volatility driven by sector-specific dynamics. While defense contractors typically benefit from geopolitical tensions and procurement cycles, NOC's muted performance indicates potential near-term profit-taking following recent gains. The surge in trading volume without a corresponding price rebound highlights diverging investor sentiment between fundamental demand and speculative positioning.
Analysts note that NOC's valuation remains anchored to its core defense contracts and R&D pipeline. With no material earnings or contract announcements reported in recent coverage, the price action appears more reflective of broader market rotation than company-specific developments. Institutional investors have shown mixed signals, with some trimming positions ahead of potential fiscal Q3 reporting season.
To run this back-test cleanly I need a few implementation details that weren’t specified: 1. Stock universe • All U.S. listed common stocks (NYSE + NASDAQ + AMEX) – default I would use CRSP-style coverage. • Or a narrower universe such as S&P 1500, Russell 3000, etc. 2. Ranking rule • Rank on the previous day’s dollar volume (price × shares traded) so you can form positions at today’s open (realistic), • or rank on the same day’s volume and trade at the close (requires intraday execution capability). 3. Trade prices • Open-to-close (buy at today’s open, exit at today’s close), • or close-to-close (buy at yesterday’s close, exit at today’s close). 4. Transaction costs / slippage – ignore by default, or specify a round-trip cost. Because the strategy holds a portfolio of 500 names that changes daily, it is more complex than the single-ticker/event back-test engine that’s built into this chat interface. I can still run it, but I need to generate a daily portfolio file first using the rules you confirm above, then feed that into the engine.
