Dividend glossary

Beta

Beta measures how much a stock or fund tends to move relative to the S&P 500. Beta of 1.0 moves with the market. Below 1.0 is less volatile. Above 1.0 amplifies market moves in both directions.

In more depth

Beta is calculated from historical price data and represents market sensitivity, not investment quality. Dividend-focused stocks in consumer staples, utilities, and healthcare typically have lower betas — which appeals to retirees who want income without extreme portfolio volatility.

Reading beta numbers

  • Beta 0.5: When the S&P 500 falls 10%, this typically falls ~5%
  • Beta 0.85: Moves roughly 85% as much as the market — SCHD and VYM typically fall in this range
  • Beta 1.0: Tracks the market closely
  • Beta 1.5: Amplifies moves — a 10% market decline might mean 15% for this holding

Beta for major dividend ETFs (approximate)

  • SCHD: ~0.80–0.85
  • VYM: ~0.80–0.90
  • VIG: ~0.85–0.90
  • Utilities sector: ~0.50–0.65
  • S&P 500 (SPY): 1.0 (by definition)

Why lower beta matters in retirement

A portfolio with beta 0.75 falls roughly 25% less than the market in a correction. For a retiree who needs dividend income to be uninterrupted, a less volatile portfolio reduces the psychological pressure of large paper losses — and reduces the risk of panic-selling at the worst time.

However, lower beta also means less participation in strong bull market rallies. The trade-off is intentional: dividend income portfolios typically sacrifice some upside for more stable, predictable performance.

Beta's limitation

Beta is backward-looking. A historically low-beta stock (say, a bond-like utility) can become volatile during interest rate regime changes when the market reprices long-duration assets. Beta should be treated as a useful guide rather than a guarantee of future stability.
