Overcoming Bias: A Path to Investment Success
"We see what we want to see. Overcoming that bias is a big step forward to investment success."
It's fascinating how our pre-existing political beliefs can influence our perception of the performances in the Republican presidential debates. As investors, we can learn valuable lessons from this phenomenon. Whether you support Nikki Haley, Ron DeSantis, or Donald Trump, acknowledging that your assessment is colored by your political leanings is crucial.
It becomes apparent that we tend to see what we want to see. Overcoming this bias requires a willingness to engage with those holding different opinions, truly listening to their perspectives, being open to new information, and even being humble enough to change our minds.
Interestingly, research conducted by Matthew Vorsatz for his Ph.D. dissertation at the University of Chicago indicates that applying these lessons to our investment decisions can enhance our portfolio's performance. The study titled "Costs of Political Polarization" focused on analyzing the impact of political partisanship on investment performance.
Vorsatz analyzed three distinct groups of U.S. equity mutual funds: those managed predominantly by Democrats, those managed predominantly by Republicans, and those managed by politically neutral teams. Surprisingly, he discovered that "partisan fund teams — whether Democratic or Republican — have lower fund returns… than non-partisan teams."
The question then arises: what accounts for this discrepancy? Vorsatz determined that non-partisan teams possessed an advantage due to their cognitive and ideological flexibility. This flexibility allows them to process and react more effectively to new information.
The study's findings shed light on the detrimental effects of political polarization, which have even seeped into the investment world. It serves as a stark reminder that as investors, we must strive to overcome our biases and embrace an open-minded approach to achieve success.
The Impact of Political Polarization on Investment Professionals
New research suggests that the detrimental effects of extreme political polarization have not spared investment professionals. While previous studies had highlighted these effects on retail investors, institutional managers were believed to be immune due to their financial acumen, financial incentives, and accountability to benchmarks. However, this new research by Vorsatz reveals that even these factors are no longer sufficient in shielding them from the consequences of political polarization and partisanship.
The implication of this research is clear: it is unwise to conduct investment analysis in the echo chamber of the internet. Online platforms provide ample justifications that support one's own beliefs, even when those beliefs are leading to financial losses. To counteract this bias, it is advisable to engage in regular discussions about investment ideas and beliefs with individuals who hold opposing political views. For instance, investors supporting President Joe Biden's re-election should seek insights from fans of former president Donald Trump, and vice versa.
Admittedly, given the extreme polarization in the United States today, reaching out to those with differing political beliefs may seem counterintuitive. However, this raises the question of whether clinging stubbornly to partisan views is more important than achieving optimal investment performance.
