The Virtue of Complexity in Return Prediction
This article explores how researchers forecast market returns by aggregating expected returns from individual stocks.
Is It Time to Ditch International Stocks?
Since 2010, the S&P 500 has beaten the International Developed market in all but three years. This led the U.S. market to outperform International Developed by an astounding 8.14% compounded per year. Wowza! Talk about pain if you’re a global investor.
Growth Predictions, Growth Surprises, and Equity Returns
What matters is not the expectation of future growth, but the deviation between projected growth and realized growth, which, by definition is a surprise, and, thus, is not forecastable.
Academic Anomalies Formed After Information Events
The hurdles to adding alpha for active managers are getting higher—investment practitioners make use of it as soon as or shortly after it is available.
Overvalued or New Paradigm?

Lottery Preference and Biotech Stocks: Trust the Financials, Not the Science
Making a bet on biotech/pharma firms that have not yet achieved significant revenue is the equivalent of buying a lottery ticket—with the same poor risk/return relationship.
Are stock returns predictable at different points in time?
For many benchmark predictor variables, short-horizon return predictability in the U.S. stock market is local in time as short periods with significant predictability (“pockets”) are interspersed with long periods with no return predictability.
Dissecting the Investment Factor
Investment predicts returns because, given expected profitability, high costs of capital imply low net present value of new capital and low investment, and low costs of capital imply high net present value of new capital and high investment.
High-Frequency Consumer Spending Data and the Cross-Section of Stock Returns
Consumer demand drives the cash flows of consumer-oriented companies. Thus, they should serve as a reliable source of information to predict future fundamentals above and beyond the information contained in financial statements and readily available market data.
How to Predict Stock Returns (using a simple model)
Jack Bogle, the founder of Vanguard, created a simple explanation for predicting future stock returns. The so-called “Occam's razor” (law of parsimony) approach is an [...]
