Is This Defense Stock Still the Smartest Buy After Its Big Run?

Howmet Aerospace has gained 500% over the past three years, with recent segment growth of 48% in commercial aerospace, 39% in gas turbines, and 13% in defense. The company also carries an A- credit rating, net leverage of 0.9x, double-digit free cash flow margins, and returned $450 million to shareholders in Q1, while its dividend has grown for five straight years. The article is a bullish stock-pick piece rather than new material news, so the likely market impact is limited.

Analysis

HWM is not just a defense proxy; it is a leverage play on three capex cycles that are all likely still in mid-innings. The market tends to underappreciate how much of the rerating comes from mix shift: high-spec engine components and turbine content typically expand operating leverage faster than headline volume, so the next leg is less about unit growth and more about margin durability as pricing resets roll through the book.

The second-order winner is the broader aerospace supply chain. If HWM keeps compounding at this pace, it signals that Tier 2/3 suppliers with certification-heavy parts, tight qualification moats, and low customer concentration can still take share from prime contractors without taking program risk. That puts pressure on names like BA and, to a lesser extent, LMT to keep vertical integration disciplined; primes can win awards, but suppliers capture the cleaner economics when aftermarket and spares grow faster than new-build.

The main risk is valuation compression, not fundamental decay. A stock that has already rerated on growth + balance sheet quality becomes vulnerable if commercial aerospace deliveries normalize or defense revenue decelerates into the low-double digits over the next 2-4 quarters. The consensus appears to be treating HWM as a quality compounder, but the more important question is whether the current multiple already discounts several years of elevated FCF conversion and buybacks.

Contrarian angle: the “not a pure-play defense name” label may actually be an advantage, because it lowers policy and procurement concentration risk while preserving defense optionality. If investors are crowding into pure primes for geopolitical reasons, HWM may remain the better way to express the theme with less earnings volatility and more shareholder yield, especially if gas turbine demand stays sticky and commercial aerospace supply tightness persists.

Key Decisions for Investors

• Go long HWM on a 6-12 month horizon, but size as a quality compounder rather than a defense beta trade; target a 12-15% upside band with a stop if commercial aerospace growth rolls over for two consecutive quarters.
• Pair trade: long HWM / short BA over 3-6 months to express supplier-outperforms-prime dynamics; thesis is that HWM captures better margin conversion and buyback support while BA remains operationally constrained.
• Add LMT only on pullbacks if you want defense exposure, but prefer HWM as the cleaner risk/reward because it benefits from defense without prime-contract execution risk.
• Sell covered calls against an existing HWM position at ~8-12% out-of-the-money for the next 1-2 quarters; use elevated implied volatility to monetize the risk that the stock consolidates after a large multi-year run.
• Watch for any sign of gas turbine order deceleration; if that segment slows materially, reduce exposure quickly since the stock’s current premium likely depends on all three growth levers firing simultaneously.
