Roger G. Ibbotson, PhD, and Laurence B. Siegel join Lotta Moberg, PhD, CFA, to continue their discussion of Exponential Wealth: Centuries of Stock and Bond Returns, a forthcoming CFA Institute Research Foundation book. This conversation focuses on the construction of long-run stock and bond market indices and the challenges of measuring returns across centuries of financial history. Ibbotson and Siegel examine index methodologies, including market capitalization weighting, equal weighting, and free-float adjustments, and discuss what investors can learn from historical data about concentration, volatility, survivorship bias, and the small-cap premium. The conversation also explores the book's international perspective, drawing on centuries of market data from around the world to provide context for capital market forecasts and long-term investment decisions.

The book is organized into four sections covering stock and bond return history, the past 100 years in US markets, centuries of US and global returns, and forecasts for the future.
