Why stock market volatility can trigger financial bias

by Phil Clerkin on October 14, 2025

When markets experience volatility, even the most level-headed investor can let their emotions or other influences affect their decisions. Read on to find out why volatility can trigger financial biases and how these might affect you. 

For the average investor, it’s important to take a long-term approach. While returns cannot be guaranteed, investing over a longer time frame gives markets more time to smooth out their natural peaks and troughs.

Headlines about market crashes or sudden rallies can set you on edge even if you’re usually calm. 

Volatility affects investors because uncertainty triggers an emotional response. When you’re thinking logically, you might note that markets have historically recovered from downturns. However, it’s easy for worries to creep in. You might ask yourself: “What if the market doesn’t recover this time?”

As investments are typically tied to personal goals, these initial worries can spiral, allowing emotions to drive your decisions. 

4 types of bias that could affect your investment decisions during volatility 

1. Herd mentality 

When there’s uncertainty in the market, it’s natural to look at what other people are doing. It can often seem like everyone else is taking the same approach. This can lead to a bias known as “herd mentality”, where you’re tempted to follow the crowd. 

It might feel like there’s safety in numbers, but it’s important to avoid making decisions that aren’t right for you just because others are doing the same. 

2. Loss aversion

No one wants to see the value of their investments fall, and psychological research suggests that investors fear losses more than they enjoy gains. So, to avoid or reduce losses, investors might sell because they’re worried markets will fall further.

However, this may lead to investors turning paper losses into actual ones. In contrast, sticking to your long-term plan and being patient could mean you benefit from a market recovery.

3. Recency bias

The theory behind recency bias argues that investors place too much emphasis on recent events. So, you might decide that a dip in the market is actually part of a long-term trend, even if the data suggests otherwise.

Taking a step back to look at the bigger picture could help you keep recency bias in check. 

4. Confirmation bias

Confirmation bias refers to the tendency of investors to seek out information that supports their existing views. 

If you’re worried about markets falling, confirmation bias can lead you to dismiss positive data in favour of negative information. This bias can intensify your fears and lead you to make decisions based on only a small portion of the available data. 

Practical ways to reduce the effect biases have on your investment decisions 

Emotions and bias interfering with your logical decision-making is normal, but that doesn’t mean it’s harmless. Successful investors manage short-term market movements so they can stick to their long-term plan and adjust when it suits them.

Here are some strategies you could try next time you’re tempted to respond to market volatility.

1. Review your financial plan

Before you make any changes to your investments or financial plan, take some time to revisit it. Your plan should centre on your goals and circumstances, so revisiting it could remind you why you chose your strategy and why sticking with it could be beneficial. 

2. Reduce your exposure to the news

It can be hard to escape headlines and constant updates, but limiting your exposure might be useful. You may reduce how frequently you check the news, log on to social media, or even monitor the performance of your portfolio.

Be mindful of the source of the information as well – is the source likely to present changes to the market negatively or exaggerate the effects?

3. Look at the historical data

Investment returns cannot be guaranteed, but looking at past performance might be a useful exercise if you’re tempted to make knee-jerk decisions. Historically, markets have recovered and grown over the long term, even after sharp drops.

4. Talk to your financial planner

Finally, your financial planner can offer valuable advice as they understand your circumstances and goals. Talking through the options could highlight where bias might be influencing your decisions and offer a different perspective that allows you to remain focused on your long-term goals.

Guide: 12 practical reasons to write a will and name a Lasting Power of Attorney

by Phil Clerkin on September 9, 2025

Thinking about what might happen after you die isn’t easy. It’s hard to imagine the world simply continuing. That’s likely one reason why so many people put off writing a will for “another time” or decide to “sort it later”. But the reality is, none of us know when we’ll die. 

Having a will in place means your estate will be dealt with according to your wishes. It will also spare your loved ones from having to deal with working out how to manage your affairs while they’re still navigating their grief. You can cover important issues such as:

  • Appointing a guardian for any children or dependants
  • Deciding how to leave your property
  • Taking steps to protect unmarried partners or stepchildren
  • Reducing the amount of Inheritance Tax (IHT) applied to your estate. 

A Lasting Power of Attorney (LPA) is another important consideration in your later-life planning. While we all hope to maintain good physical and mental health, you just don’t know what’s around the corner. An LPA means that you know people you trust will be making decisions about key areas of your life, such as your healthcare and finances. 

In this guide, you can find out more about how making a will and setting up an LPA can give you and your loved ones peace of mind about the future.
