What is the difference between growth and value investing styles, and how are they defined for CFA Level I?

I'm confused about growth vs. value investing. Some sources define it by P/E ratios, others by earnings growth expectations. For the CFA exam, how are these styles formally defined? What are the key metrics that distinguish them, and which has historically performed better?

Growth and value are the two primary equity style categories used in investment management and index construction. The distinction matters for portfolio construction, benchmark selection, and performance attribution.

Formal Definitions (per CFA curriculum):

Price-to-Book (P/B)LowHigh
Dividend YieldHighLow or zero
Earnings Growth RateBelow averageAbove average
Payout RatioHighLow (reinvests)

Value Investing Logic: Buy stocks trading below intrinsic value. The market has over-penalized them for short-term problems, creating a margin of safety. Returns come from mean reversion.

Growth Investing Logic: Buy stocks with above-average earnings growth potential. Even though prices are high relative to current earnings, future earnings growth will justify the premium.

Example:

  • Hargrove Industries (fictional): P/E = 9x, P/B = 0.8x, dividend yield = 4.5%, earnings growth = 3%. This is a classic value stock.
  • Zenith Dynamics (fictional): P/E = 35x, P/B = 8x, dividend yield = 0%, earnings growth = 28%. This is a classic growth stock.

Historical Performance:

Value has historically outperformed growth over very long periods (the 'value premium'), but growth has dominated in recent cycles, particularly during the 2010-2021 era of low interest rates. The CFA curriculum notes that the value premium varies over time and across markets.

Exam Tip: Know the classification metrics and understand that most index providers (MSCI, Russell, S&P) use multiple factors — not just P/E — to classify stocks into growth or value buckets.
