Understanding Regret Avoidance in Investing

Regret avoidance, also called regret aversion, describes why investors often refuse to acknowledge poor investment choices. This emotional bias leads investors to cling to losing positions or even increase their stakes, hoping to recover losses and sidestep feelings of regret. This pattern is sometimes referred to as escalation of commitment.

Key Insights

• Regret avoidance drives people to make emotional decisions rather than logical ones to escape regret.
• Investors may stubbornly hold or add funds to underperforming assets, anticipating a rebound.
• This behavior stems from a desire to avoid regretting the initial purchase.
• Ultimately, it often results in greater financial losses than if the investor had acted sooner.

The Psychology Behind Regret Avoidance

Regret avoidance occurs when individuals invest excessive time, money, or effort to prevent admitting a poor decision. Sometimes, the resources spent to justify the original choice surpass the initial investment’s worth. For example, someone might keep repairing a faulty car, spending more than its value, rather than accept the mistake and buy a new vehicle.

Financial therapist George M. Blount explains, “People tend to make irrational choices when decisions are rushed, lack context, or are made without sufficient knowledge. This can cause anxiety and regret later on.”

Regret Avoidance in the 2008 Housing Collapse

During the 2008 housing crisis, many homeowners refused to abandon underwater mortgages despite plummeting property values. Studies showed homeowners only considered walking away when their home’s value fell below 75% of what they owed. Emotional ties and the fear of losing prior investments delayed rational decisions to exit, prolonging financial pain.

Behavioral Finance and Emotional Investing

Behavioral finance studies why investors often make irrational financial choices. Regret avoidance exemplifies this, as decisions are driven by emotion rather than logic. Investors tend to overvalue past expenditures and try to recover losses instead of cutting them early.

This mindset leads to the sunk-cost fallacy, where individuals continue investing in failing assets to justify previous losses, fearing that changing course means admitting failure and experiencing regret.

The Concorde Fallacy: A Classic Example

The “Concorde Fallacy” illustrates regret avoidance in action. The British and French governments kept funding the Concorde airplane project long after it lost economic viability. Officials avoided canceling the project to escape the embarrassment of wasted funds, resulting in a costly commercial failure.

How to Overcome Regret Avoidance

Understanding behavioral finance, crafting a disciplined investment plan, and knowing your risk tolerance helps prevent destructive regret avoidance. Establish strict trading rules—such as exiting a stock after a 7% loss or using trailing stops to protect gains—and stick to them without emotional interference.

Automating trading strategies through algorithms and robo-advisors can reduce emotional bias and improve decision-making consistency. Backtesting these strategies also helps identify personal biases and refine investment approaches.

Regret Aversion’s Role in Market Crashes

Regret aversion often intertwines with FOMO (fear of missing out), especially during prolonged bull markets. Investors driven by the fear of missing profits may ignore warning signs, fueling irrational exuberance—a term popularized by Alan Greenspan describing overenthusiastic market optimism.

This excessive optimism inflates asset bubbles, which eventually burst, triggering panic selling and economic recessions. Historical examples include the 1929 and 1987 stock crashes, the 2001 dotcom bubble burst, and the 2007-08 financial crisis.

Frequently Asked Questions
