PB-ROE Valuation and Earnings-Expectation Discrepancies

Summary

This document explains the PB-ROE framework as a valuation relationship: higher expected return on equity is associated with higher price-to-book multiples, with log PB described as linearly related to expected ROE. It reviews the theoretical basis and discusses using historical ROE as a proxy for expectations when comparing companies, while noting that the relationship may fit better within narrower industries and smaller-cap stocks.

The selection approach estimates the market-implied ROE for a given PB level by regression, then compares it with an investor’s own ROE forecast. Stocks whose forecast exceeds the implied expectation may be candidates for further analysis. The article reports that large-cap and small-cap portfolios based on ROE expectation gaps more consistently outperformed their benchmarks in its backtests, and also considers analyst consensus and historical data as inputs. The available text gives no detailed backtest period, portfolio construction, transaction costs, or risk statistics, so it does not establish how robust or transferable those results are.

Key ideas

• The framework links higher expected ROE with higher PB valuation.
• Regression can estimate the ROE implied by a stock’s PB as a proxy for market expectations.
• An investor may screen for an expectation gap when their ROE forecast exceeds the market-implied estimate.
• The document says model fit improves with narrower industry groups and is stronger among smaller-cap stocks.
• Reported portfolio outperformance lacks detailed backtest conditions in the available text.
