What drives persistent valuation dispersion across industry peer stocks?

Persistent differences in market prices for otherwise similar companies arise from a combination of information, behavioral, structural, and institutional forces. Empirical and theoretical work shows that prices reflect not only fundamentals but also how information is processed, who can act on it, and how markets and accounting systems reveal value.

Behavioral and informational drivers

Information asymmetry and investor sentiment create diverging valuations. Robert J. Shiller Yale University documents how sentiment and narrative can move multiples independently of cash flows. Behavioral research by Richard H. Thaler University of Chicago explains systematic biases that cause investors to overweight recent performance or dramatic stories, producing sustained gaps among peers. Market analysts and media concentrate attention unevenly; firms headquartered in high-visibility regions may trade at premium multiples even when fundamentals are comparable, an effect amplified in sectors rich in intangible promise such as technology.

Limits to arbitrage and structural frictions

Structural obstacles prevent quick correction of mispricing. Andrei Shleifer Harvard University and Robert W. Vishny University of Chicago highlight limits to arbitrage: regulatory constraints, funding risk, and behavioral pressures on arbitrageurs can make it costly to bet against popular overvalued stocks. Factor research by Eugene F. Fama University of Chicago and Kenneth R. French Dartmouth College shows that size, book-to-market, and profitability factors explain part of cross-sectional valuation differences, indicating persistent systematic drivers beyond idiosyncratic noise.

Accounting, intangibles, and institutional context

Accounting rules and the prevalence of intangible assets skew comparability. Baruch Lev New York University Stern argues that current accounting practices understate the value of research, brand, and human capital, leading to dispersion as analysts apply different adjustments. Legal protections, corporate governance norms, and market depth vary across territories; firms operating in jurisdictions with stronger investor protections generally enjoy higher valuations, producing cross-border dispersion grounded in institutional differences.
