Empirical measures of world consumption growth risk have failed to rationalize the cross-section of country equity returns. We propose a new factor, termed "the global consumption factor", to explain the patterns in risk premiums on international equity markets. We identify this factor as the...

We study firm-level characteristics that a manager would employ as signalling tools in order to time the market (i.e. repurchases and issues). Following the market timing framework, we develop a two-factor asset pricing model comprising a “market” and a “mispricing” factor, which is able...

Because dividends are taxed at a higher rate than capital gains, as stock with a higher yields should have a higher expected return than a stock whose return is expected to result mostly from price appreciation. Adding yield to the traditional Security Market Line results in a "market plane"...

In this paper we examine the characteristics and stability of individual stock and portfolio betas of stocks listed in the Istanbul Stock Exchange (ISE) using samples of 500 individual stocks and 500 portfolios of 10 stocks each. We begin with a methodology similar to the basic event study...

This paper examines real-time applications of quickest disorder detection techniques for timing stock markets. The focus is on the stochastic disorder model by Shiryaev, Zhitlukhin, and Ziemba (2014, 2015), Zhitlukhin and Ziemba (2016) and their optimal stopping rule. The model uses sequential...

This study shows how correlated information consumption (CIC) of retail investors relates to comovement in stock market outcomes. We construct clusters of stocks with CIC by employing network analysis on Google co-search data. We predict significant comovement in returns and liquidity of stocks...

Most papers in the portfolio choice literature have examined linear predictability frameworks based on the idea that simple but flexible Vector Autoregressive (VAR) models can be expanded to produce portfolio allocations that hedge against the bull and bear dynamics typical of financial markets...

This paper presents three definitions of time diversification and analyzes their implications for investment horizons. Using decision quality criteria and methodology, we question standard advice. In analyzing time diversification with a minimum of assumptions, we answer two main questions: how...

Existing studies of household stock trading using administrative data offer conflicting results: Discount brokerage accounts exhibit excessive trading, while retirement accounts show inactivity. This paper uses population-wide data from PSID and SCF to examine the overall extent of household...

With the intention of maximizing an investor's terminal utility, we construct a non-threshold ased trading model within which the optimal trading weights for daily rebalancing are derived analytically via stochastic optimal control. Having released the constraint that the cointegrating vector is...
