These Five Cognitive Biases Hurt Investors the Most



There is no shortage of cognitive biases out there that can trip up our brains.

By the last count, there are 188 types of these fallible mental shortcuts in existence, and they constantly impede our ability to make the best decisions about our careers, our relationships, and for building wealth over time.

Biases That Plague Investors

In today’s infographic from StocksToTrade, we dive deeper into five of these cognitive biases – specifically the ones that really seem to throw investors and traders for a loop.

Next time you are about to make a major investing decision, make sure you double-check this list!

The Five Cognitive Biases That Hurt Investors the Most

The moves that may seem instinctual for the average investor may actually be pre-loaded with cognitive biases.

These problems can even plague the most prominent investors in the world – just look at JPMorgan’s Jamie Dimon!

Biases to Avoid

Here are descriptions and examples of the five cognitive biases that can impact investors the most:

Anchoring Bias
The first piece of information you see or hear often ends up being an “anchor” for others that follow.

As an example, if you heard that a new stock was trading at $5.00 – that is the piece of information you may reference whenever thinking about that stock in the future. To avoid this mental mistake: analyze historical data, but don’t hold historical conclusions.

Recency Bias
Recency bias is a tendency to overvalue the latest information available.

If you heard that a CEO is resigning from a company you own shares of, your impulse may be to overvalue this recent news and sell the stock. However, you should be careful, and instead focus on long-term trends and experience to come up with a more measured course of action.

Loss Aversion Bias
No one wants to lose money, but small losses happen all the time even for the best investors – especially on paper.

Loss aversion bias is a tendency to feel the effects of these losses more than wins of equal magnitude, and it can often result in a sub-optimal shift in investing strategy. Investors that are focused only on avoiding losses will miss out on big opportunities for gains.

Confirmation Bias
Taking in information only that confirms your beliefs can be disastrous. It’s tempting, because it is satisfying to see your previous conviction in a positive light – however, it also makes it possible to miss important findings that may help to change your conviction.

Bandwagon Bias
No one wants to get left out, but being the last one to pile onto an opportunity can also be cataclysmic. If you’re going to be a bandwagon jumper, make sure you’re doing it for the right reasons.

Ranked: The World’s 50 Top Countries by GDP, by Sector Breakdown

This graphic shows GDP by country, broken down into three main sectors: services, industry, and agriculture.



Visualized: The Three Pillars of GDP, by Country

Over the last several decades, the service sector has fueled the economic activity of the world’s largest countries. Driving this trend has been changes in consumption, the easing of trade barriers, and rapid advancements in tech.

We can see this in the gross domestic product (GDP) breakdown of each country, which gets divided into three broad sectors: services, industry, and agriculture.

The above graphic from Pranav Gavali shows GDP by country, and how each sector contributes to an economy’s output, with data from the World Bank.

Drivers of GDP, by Country

As the most important and fastest growing component of GDP, services make up almost 60% of GDP in the world’s 50 largest countries. Following this is the industrial sector which includes the production of raw goods.

Below, we show how each sector contributes to GDP by country as of 2021:

Industrial sector includes construction. Agriculture sector includes forestry and fishing. *Data as of 2019.

In the U.S., services make up nearly 78% of GDP. Apart from Hong Kong, it comprises the highest share of GDP across the world’s largest economies. Roughly 80% of American jobs in the private sector are in services, spanning from healthcare and entertainment to finance and logistics.

Like America, a growing share of China’s GDP is from services, contributing to almost 54% of total economic output, up from 44% in 2010. This can be attributed to rising incomes and higher productivity in the sector as the economy has grown and matured, among other factors.

In a departure from the top 10 biggest countries globally, agriculture continues to drive a large portion of India’s GDP. India is the world’s second largest producer of wheat and rice, with agriculture accounting for 44% of the country’s employment.

While the services sector has grown in India, it makes up a greater share in other emerging economies such as Brazil (58%), Mexico (59%), and the Philippines (61%).

Growth Dynamics

Services-led growth has risen faster than manufacturing across many developing nations, underpinned by productivity growth.

This structural shift is seen across economies. In many countries in Africa, for instance, jobs have increasingly moved from agriculture to services and trade, where it now accounts for 42% of jobs.

These growth patterns are supported by rising incomes in developing economies, while innovation in tech is lowering barriers to enabling service growth. As the industrial sector makes up a lower share of trade and economic activity, the service sector is projected to make up 77% of global GDP by 2035.
