View all 1823 holding institutions

Across its top 20 institutional holders, NOC's holder base skews toward low-concentration, low-turnover investors on average (avg. concentration score 5/100, avg. turnover score 31/100).

Notable Holders

NOC ranks #174 out of 37501 tracked stocks by institutional interest — one of the most closely watched names in our coverage.

1823 institutions disclose a position in NOC, but none treat it as a major bet — even Mawer Investment Management Ltd., its most concentrated holder, allocates just 2.3% of its own portfolio to it.

MIRAE ASSET GLOBAL ETFS HOLDINGS Ltd. has added to its NOC position for two straight quarters, increasing it by $333.1M to reach $601.1M today.

Capital International Investors has trimmed its NOC position for two straight quarters, cutting it by $3.6B while still holding $3.0B.

NOC is down 1.3% today, but institutions show net buying of $29.5B this quarter — a divergence between today's price move and the underlying institutional flow.

Game Theory Scenarios

Neutral— Wait & Watch

Institutional inflows and insider-only selling create mixed signals

Signal Basis

13F filings show a large net value increase of approximately $29.5 billion, yet net sellers (853) outnumber net buyers (838) and exits (204) exceed new buys (131), indicating accumulation is concentrated among fewer large institutions rather than broad-based. On the insider side, Form 4 data over the trailing 90 days shows zero insider purchases and 10 sells by a single director totaling roughly $52,000 — directionally bearish but negligible in magnitude.

Confirmation

A subsequent 13F quarter showing net buyer count exceeding net seller count alongside any insider buy transactions would confirm a bullish convergence.

Invalidation Risk

If institutional net value change turns negative and insider selling broadens beyond a single director, the bearish case would be firmly established.

Generated by AI directly from institutional holders' Form 13F data on SEC EDGAR, reflecting past activity only. Not investment advice — do not base trading decisions on this alone; verify against the source filings below.

Smart Money Convergence

NOC does not currently show a 13F-and-insider convergence signal — its insider confidence score is 0/100, below the threshold this product uses to flag combined buying pressure.

13F data as of 2026-06-30 quarterly filings. Note: many large institutions file close to the 45-day post-quarter deadline, so early-quarter flow figures can shift substantially as more filings arrive.

On August 19, 2026, Northrop Grumman's (NOC) independent directors approved a one-time performance-based equity award for Chair, CEO and President Kathy J. Warden. The grant targets 35,910 Market Stock Units (MSUs), and what she actually receives depends on the stock's absolute price move through December 31, 2031: a drop of more than 25% means zero payout, at least 10% appreciation earns the full target amount, and a gain of 50% or more pays out the maximum of 150%. She also has to remain with the company throughout the performance period to earn anything.
