How behavioral finance affects our money decisions

NNatalie August 24, 2023 8:12 PM

Have you ever made a financial decision and later wondered why you did it? Ever held on to a losing stock longer than you should have, simply because you couldn't bear the thought of selling at a loss? If so, you've experienced the effects of behavioral finance. Behavioral finance is a field that studies the psychological factors that impact our financial decisions. By understanding these principles, we can make better money decisions and improve our financial health.

Understanding behavioral finance

Behavioral finance combines psychology and economics to explain why and how investors act and to analyze how that behavior affects the market. It's a contrast to traditional finance, which assumes that investors are always rational, information-processing beings, making the best decisions for their wealth growth. But the reality is often very different. We're not computers; we're humans with emotions and biases that can cloud our judgement.

Let’s discuss some of the most common cognitive biases that affect our financial decisions.

1. Loss aversion

People tend to prefer avoiding losses to acquiring equivalent gains. This is why we hold on to losing stocks, hoping they'll bounce back, instead of cutting our losses.

2. Overconfidence

Overconfidence leads to taking on excessive risk. We might think we're better at picking stocks than we actually are, leading to poor investment decisions.

3. Confirmation bias

We tend to search for, interpret, and remember information in a way that confirms our preexisting beliefs, ignoring evidence to the contrary. This can lead to financial mistakes, like sticking to a flawed investment strategy.

4. Herding behavior

This is the tendency for individuals to mimic the actions (rational or irrational) of a larger group. Think of the dot-com bubble or the housing bubble - herding behavior can lead to financial disasters.

5. Mental accounting

We often categorize money differently based on where it comes from or what we plan to do with it, leading to irrational decisions. For example, treating a tax refund as 'free money' to be spent frivolously.

How to navigate behavioral biases

Understanding these biases is the first step. The next is learning strategies to mitigate their effect on our financial decisions.

  1. Awareness: Be aware of your own biases. Acknowledge them and understand how they might affect your decisions.

  2. Take a step back: Don’t make financial decisions when you’re emotional. Take some time to cool off and reassess.

  3. Diversify your portfolio: Spread your investments across different asset classes to reduce risk.

  4. Seek professional advice: A financial advisor can provide an objective perspective and help you avoid costly mistakes.

  5. Automate your finances: Automatic contributions and a long-term investment strategy can help avoid emotional decision-making.

Behavioral finance doesn't suggest that we're all irrational or that we can't make good financial decisions. Instead, it provides a framework to understand why we often stray from the rational path and how we can correct our course. By being aware of these cognitive biases and employing strategies to combat them, we can make better financial decisions and enhance our financial well-being.
