CAPM came under a lot of scrutiny and attack as its simplicity also led to extensive testing which did not bear out the conclusions. This paper seeks to re-think CAPM in light of the broader trend in the institutional world to implement Liability Driven Investments (LDI) to see if this can help...

Tests of the conditional CAPM are often based on the joint (internally inconsistent) hypothesis that the stock portfolio used in the tests is the theoretical, mean-variance efficient, market portfolio. I derive a new test based exclusively on the theory in the conditional CAPM. According to this...

This paper theoretically reconciliates the several types of value premiums observed in cross-section with the use of aggregate scaled-price ratios - including "value spreads" - as price of risk proxies in time series. Prices in scaled-price ratios reflect risk premiums (and the price of risk),...

This paper offers theoretical, empirical, and simulated evidence that momentum regularities in asset prices are not anomalies. Within a general, frictionless, rational expectations, risk-based asset pricing framework, riskier assets tend to be in the loser portfolios after (large) increases in...

This paper theoretically links the stock characteristics size and value to risks. The size premium arises – and spans the value premium – exclusively for portfolios formed in high market price of risk states. This is when the cross-sectional differences in risk premiums dominate the...

The Capital Asset Pricing Model (CAPM) has been the backbone of asset market finance even though many academic studies have revealed its limitations, both theoretical and empirical. This paper argues that including liability or benchmark considerations in investment decisions may provide a...

This paper documents empirically that increases in the book-to-market spread predict larger market premiums in sample and larger size, value, and investment premiums (also) out of sample. In addition, increases in the investment (or profitability) spread exclusively predict larger investment (or...

Investors live in a multi-period, volatile world and base their decisions on theories of asset pricing, and asset allocation, often derived from a single period model. They make assumptions about asset returns and volatilities and use optimizers to set their long term allocations, and often...

X-value normalizes stock prices by the recursive out-of-sample expectation of each firm's net income, estimated by industry from its financials, while ignoring book equity. The resulting X-value factor is unspanned by the five Fama/French factors individually or in different combinations, and...
