Is NOC a buy, hold, or sell?
NOC carries a valuation grade of Strong Buy. At a trailing P/E of 17.0, the stock trades at a 23% discount to the Industrials sector median of 22.0x. Our discounted cash flow model produces an intrinsic range of $594–$856 — implying a +34% margin of safety at the current price of $542.14. The width of the DCF range reflects genuine uncertainty in the terminal growth rate assumption: the correct framework is a probability-weighted distribution over scenarios, not a single point estimate. See the DCF valuation framework for full methodology.
With a 12% beat rate on recent quarters, earnings predictability has been mixed. The most recent quarter delivered a 1.3% earnings surprise. Analyst estimate revisions are trending flat.
What are NOC's key risk factors?
With a beta of -0.12, NOC exhibits a low-volatility risk profile relative to the broad market. The 95th-percentile CVaR of -21.3% on a one-month horizon should inform position sizing directly: at a 10% portfolio weight, this tail event contributes approximately 2.1% of total portfolio loss in the worst 5% of months. Net margins stand at 10.8%. Return on equity of 28.5% indicates highly efficient capital allocation. Leverage is moderate with debt-to-equity at 103%.
At 0.71, the put/call ratio skews bullish, with call buyers dominating recent flow. Implied volatility of 1.0% is below realized volatility of 25.8%, potentially making options relatively cheap. Insiders have been net sellers to the tune of $35.2M recently. While routine dispositions are common, the magnitude bears watching. Short interest is low at 1.3% of float, suggesting limited bearish conviction.
How does NOC fit in a diversified portfolio?
At typical HENRY portfolio weights — 10–20% of the equity allocation — NOC carries a beta of -0.12, meaning it amplifies broad market moves proportionally. The appropriate weight is not a function of conviction alone, but of the full covariance structure across all holdings. See the Ledoit-Wolf covariance framework for the methodology behind these calculations.
Among closely correlated names, NOC shows the strongest co-movement with LHX (0.65), RTX (0.56), GD (0.51). Investors seeking diversification should note these correlation dynamics when constructing multi-asset portfolios.
True portfolio risk is a function of the full covariance structure across all holdings — not individual stock metrics. The Portfolio Health Check quantifies this at the portfolio level: it surfaces hidden concentration, marginal CVaR contributions, and the degree to which your overall allocation deviates from an optimal risk-adjusted mandate. The NOC analysis here is a single node in that larger structure.
