(Car)Bon Voyage: The Road to Low Carbon Investment Portfolios

We discuss how an investment portfolio could dramatically reduce its carbon footprint, potentially even achieving a ‘net zero’ carbon footprint. We discuss the pros and cons of techniques to achieve carbon reduction goals, including security selection, shorting high carbon footprint companies, and trading instruments such as carbon offsets and carbon permits.

Macroeconomics

It’s Not a Bound; It’s an Opinion

In the second paper of our “Bonds Today” series, we review the popular belief that bond yields are too close to zero to fall much further and then explain why we disagree.

Asset Allocation

Don’t Hate the Asset; Hate the Constraint

What role do bonds play in a portfolio today? We explain why it all depends on investors’ ability to own them in a capital efficient way.

Tail Risk Hedging: Contrasting Put and Trend Strategies

The sharp market fall and speedy recovery during the eventful first half of 2020 has kept tail risk hedging topical: investors have both fresh memories of a painful loss and renewed fears of a repeat. We try to offer a balanced overview of the strengths and weaknesses of direct and indirect tail hedging strategies.

Understanding a Tax-Aware Defensive Equity Long-Short Strategy

We describe a hypothetical Tax-Aware Defensive Equity Long-Short strategy, including its construction and pre-tax and after-tax performance. The strategy closely replicates the pre-tax performance of a similar hypothetical tax-agnostic strategy and has the potential to achieve a meaningful tax benefit for a taxable investor.

Equities

Equity Term Structures without Dividend Strips Data

We use a large cross-section of equity returns to estimate a rich affine model of equity prices, dividends, returns and their dynamics.. The new term structure data generated by our model represent new empirical moments that can be used to guide and evaluate asset pricing models.

Enhanced Portfolio Optimization

We show how to identify the portfolios that cause problems in standard mean-variance optimization (MVO) and develop an enhanced portfolio optimization (EPO) method that addresses the problems. Applying EPO on several realistic datasets, we find significant gains relative to standard benchmarks.

Alternative Investing

Market Crashes and Merger Completions

A primary concern in mergers and acquisitions is the risk that the deal may be cancelled before completion. We document that this "interim risk" varies asymmetrically with the aggregate stock market: When the market falls sharply, cash deals are more than twice as likely to be cancelled.
