In this paper, we propose a stop-loss strategy to limit the downside risk of the well-known momentum strategy. At a stop-level of 10%, we find, with data from January 1926 to December 2013, that the maximum monthly losses of the equal- and value-weighted momentum strategies go down from -49.79%...

This paper introduces a new algorithm for exploiting time-series predictability-based patterns to obtain an abnormal return, or alpha, with respect to a given benchmark asset pricing model. The algorithm proposes a deterministic daily market timing strategy that decides between being fully...

Mutual fund families are increasingly assigning traders to manage corporate bond mutual funds. Using this setting to study the role of traders in investment management, we document that trader managers identify and exploit short-term trading opportunities at lower transaction costs. These skills...

Optimal investment of firms implies that expected stock returns are tied with the expected marginal benefit of investment divided by the marginal cost of investment. Winners have higher expected growth and expected marginal productivity (two major components of the marginal benefit of...

This is the first study to investigate the profitability of Barroso and Santa-Clara's (2015) risk-managing approach for George and Hwang's (2004) 52-week high momentum strategy in an industrial portfolio setting. The findings indicate that risk-managing adds value as the Sharpe ratio increases,...

When long-term investors trade slowly changing portfolios, they are not particularly sensitive to when they should place or modify their bets. Short-term information can be used to guide investors on how to time their trades. Strategic trade modification provides exposure to short-term signals...

Most existing text-based sentiment measures in finance are lexicon-based which are effectively based on word counts of positive and negative sentiment dictionaries, and naturally lose most information. We measure news sentiment using BERT, a state-of-the-art large language model, which reads and...

We explore the use of an option selling overlay to improve portfolio rebalancing. Within a multi-asset class portfolio, portfolio weights deviate from targets as asset values fluctuate. Investors typically use a rebalancing process to bring portfolio weights back to their desired strategic...
