According to behavioral finance theory, investors are not the rational actors that economic theory describes. Rather, they are human beings whose decision-making can be driven by cognitive and emotional factors. Research evidence shows innumerable examples of investors behaving in ways that are...

We decompose consensus analyst long-term growth forecasts into a hard growth component that captures accounting information (asset and sales growth, profitability and equity dilution) and an orthogonal soft growth component. The soft component does not forecast future returns, and the hard...

This paper considers several popular portfolio implementation techniques that maximize exposure to value and/or momentum stocks while taking into account transaction costs. Our analysis of long-only strategies illustrates how a strategy that simultaneously incorporates both value and momentum...

A property's location is often considered to be the ultimate determinant of its investment performance. But how exactly does a property's location influence its risk and return? We focus on the effects of location density on the risk and return of commercial real estate investments. We do this...

We find that accounting ratios (asset and sales growth, profitability, and equity dilution) that predict stock returns are associated with errors in analyst long-term growth forecasts. Specifically, accounting information that is associated with favorable long-term growth forecasts tends to...

I prove that if markets are efficient, meaning current prices fully reflect all information available in past prices, then P = NP, meaning every computational problem whose solution can be verified in polynomial time can also be solved in polynomial time. I also prove the converse by showing how...
