Is LMT a buy, hold, or sell?
LMT carries a valuation grade of Reduce. The trailing P/E of 24.9 sits 13% above the Industrials sector median of 22.0x — a premium that demands sustained earnings delivery. Our discounted cash flow model produces an intrinsic range of $527–$857 — implying a +34% margin of safety at the current price of $514.46. 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 6% beat rate on recent quarters, earnings predictability has been mixed. The most recent quarter missed by a 3.8% earnings surprise. Analyst estimate revisions are trending upward.
What are LMT's key risk factors?
With a beta of 0.11, LMT exhibits a low-volatility risk profile relative to the broad market. The 95th-percentile CVaR of -19.5% on a one-month horizon should inform position sizing directly: at a 10% portfolio weight, this tail event contributes approximately 1.9% of total portfolio loss in the worst 5% of months. Net margins of 6.4% fall below the Industrials sector average of 11%, suggesting margin pressure. Return on equity of 67.6% indicates highly efficient capital allocation. Debt-to-equity of 276% warrants monitoring for leverage risk.
At 0.00, the put/call ratio skews bullish, with call buyers dominating recent flow. Implied volatility of 2.2% is below realized volatility of 33.6%, potentially making options relatively cheap. Insiders have been net sellers to the tune of $18.0M recently. While routine dispositions are common, the magnitude bears watching. Short interest is low at 1.8% of float, suggesting limited bearish conviction.
How does LMT fit in a diversified portfolio?
At typical HENRY portfolio weights — 10–20% of the equity allocation — LMT carries a beta of 0.11, 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 reduceings. See the Ledoit-Wolf covariance framework for the methodology behind these calculations.
Among closely correlated names, LMT shows the strongest co-movement with LHX (0.55), RTX (0.51), GD (0.48). 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 reduceings — 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 LMT analysis here is a single node in that larger structure.
