Unveiling Decades of After-Tax Underperformance in Active Management

Title: Unmasking the Hidden Cost of Active Management: A Decade-Long Analysis

The Shocking Truth About Taxable Investors' Performance in the 1980s and 1990s

Investment management has long been plagued by a lack of focus on after-tax returns, with taxable investors often paying hefty fees and facing substantial tax consequences due to active trading. This problem has persisted despite the bull market and limited availability of after-tax performance data.

A Decade of Underperformance: Jeffrey and Arnott's Exploration

In 1993, Jeffrey and Arnott were among the first to study the tax consequences of active management. Their research revealed that out of 71 equity-oriented mutual funds with at least $100 million in assets throughout the decade, only 6 added value relative to the S&P 500 on an after-tax basis from 1982 – 1991.

Revisiting the Past and Peering into the Future

We expand upon Jeffrey and Arnott's work by rolling their research forward, and backward, to examine the most recent ten, fifteen, and twenty years. Our larger sample, without survivorship bias, provides a more comprehensive view of mutual fund performance. Additionally, we update this previous work by incorporating true historic federal tax rates.

The Pure Tax Effect: Separating the Impact of Taxes from Underperformance

To isolate the effects purely from taxes, we examine the difference in before-tax and after-tax performance, relative to that same difference for an index benchmark. Our findings suggest that most mutual funds not only underperform but also shed further value due to taxes.

The Irony of Taxable Funds Management: Simple Solutions with Big Impact

One of the ironies in this pattern of taxable fund management is that it is remarkably easy to add to after-tax returns with a suitable attention to the management of tax consequences. In the last section, we discuss methods to manage assets in a tax efficient manner and provide insights on when taxes do (and don't) matter.

Closing Thoughts: Navigating the Tax Maze in Investment Management

In conclusion, our analysis underscores the importance of considering taxes as an essential component of investment management. By understanding and addressing the tax implications of investment decisions, investors can potentially enhance their after-tax returns and ultimately improve their overall financial well-being.
