O'Shaughnessy Quarterly Letter Q4 2019

In 2019, we completed more research than in any prior year, built and launched Canvas, and shared 13 papers and over 50 podcasts. This letter is intened to share where markets stand at year end, and discuss what we built and learned at OSAM during 2019.

ESG the Right Way: Customization and Not Scale

In order to scale, the largest ESG products are designed to be one size fits all. This approach waters down and often tilts away from the values investors (institutional or individual) want. Poorly defined ESG screens and tilts can lead to starting universes and portfolio holdings that are not aligned with investors’ goals. We believe the best solutions are reached by tailoring portfolios to the unique goals of each investor. This paper discusses best practices in: tailoring ESG screens and tilts, combining ESG with Alpha factors to improve return expectations, and using differences in ESG data providers to solve a wider range of ESG goals.

Introducing Canvas

Today, I am excited to announce the release of Canvas, the first investing software that allows advisers and allocators to design, implement, and maintain deeply customized investment strategies. Building on OSAM’s 2+ decades of expertise in factor and systematic strategy design, Canvas hands allocators the keys to our best systems so they can design tailored strategies for their clients. Give your clients something they cannot find elsewhere—a strategy built uniquely for them.

Separate Account Strategies

We build portfolios with significant factor advantages in different style segments, market capitalization ranges, and geographic regions. Our portfolios tend to have low excess return correlation with other active strategies, little overlap with market indexes, and low active costs. We have routinely worked with clients to build custom solutions.
