How do I distinguish cyclical sectors from defensive sectors in portfolio construction?

The classification rests on beta to the business cycle and the elasticity of demand for the sector's output. Cyclicals experience earnings that swing sharply with GDP. Defensives post earnings that are insensitive to consumer budgets because the products are necessities. Classic cyclicals (beta > 1, earnings correlate > 0.6 with IP): - Consumer Discretionary — autos, hotels, luxury - Industrials — machinery, construction, airlines - Materials — chemicals, metals, forest products - Financials (especially banks) — credit quality cycles - Real Estate (selective — office, lodging REITs) - Energy — though driven more by commodity cycles Classic defensives (beta < 1, earnings volatility < 15%): - Consumer Staples — food, beverages, household products - Healthcare — pharma, managed care - Utilities — electric, water - Telecommunications (traditional) Growth/tech sits between. Some tech (semiconductors, hardware) is deeply cyclical because capex spending is pro-cyclical. Software-as-a-service with recurring revenue behaves more defensively. Example — Vanguard's approach. In a 2024 downturn call, a portfolio might rotate from Cyprus Cement (cyclical, GDP beta 1.4) into Northbrook Foods (defensive, GDP beta 0.3) to reduce drawdown risk while collecting dividend yield. A useful lens: think about whether a customer can delay the purchase. Delaying a new F-150 truck is easy (discretionary). Delaying toothpaste is not (staple). Delaying insulin is impossible (pharma). The longer the delay elasticity, the more cyclical the name. Mixed names like Walmart are defensive in the checkout aisle but discretionary in electronics — the company-level beta reflects this blended exposure.
