Welcome to Mental Models For Wall Street.

On this course we are going to investigate a number of mental models and how they can help you win in finance and business. Models like:

- The Availability Bias
- Confirmation Bias
- Misconceptions of Chance
- The Black Swan
- The Law of Small Numbers
- Cognitive Dissonance
- Margin of Safety
- Aversion to Losses
- Feedback Loops

- And lots more...

Financial traders, investors and entrepreneurs will benefit most from this course as we delve into topics that will teach you about yourself, improve your judgement skills and insulate you from costly mistakes. 

For example, by learning about psychological models like confirmation bias and hindsight bias you will be better equipped to eliminate their negative effects and make better decisions in the stock market.

By learning about cognitive dissonance, anchoring and fear of missing out you'll finally understand why you sometimes make strange, illogical decisions. And how this can help you in the trading world.

Concepts such as circle of competence, margin of safety and Mr. Market will further help you to make better timed investment moves while protecting your downside risk.

Also, you will learn to calculate better probabilities using Bayes Theorem, improve your systematic processes using feedback loops and minimise overconfidence by understanding concepts such as regression to the mean. 

You will learn all this and more – by utilising the power of mental models detailed on this course!

But, what is a mental model?

Well, a mental model in it’s simplest form is an idea that helps us understand how the world works.

Having a large array of these models at our fingertips gives us great tools we can use to solve problems and navigate life.

Why do we need mental models?

The world is complicated so you can’t rely on just remembering facts, you need to have multiple models from all different disciplines in your head.

But even though there is so much to learn, there are shortcuts we can take.

By studying the big ideas from the big disciplines. Disciplines like psychology, economics, maths, physics and engineering we can go a long way in a short amount of time.

And that’s the whole concept behind Mental Models. They're shortcuts you can take to speed up your learning and become knowledgeable about the world.

On this course, we will look at the most important mental models, the ones most crucial for success. And we will relate them to the business of financial trading and investing. 

These models will help you to make better investment decisions, solve complex problems and avoid costly errors.

Trader & Investor

Joe B Marwood is a trader and investor specialising in financial trading and mechanical trading systems.

He began his career trading stock and bond futures for a prop trading firm in London and now works through his own private company.


How did you get started?

I started my career as a professional day trader for a London-based firm where my principal products were the FTSE 100 future and German Bund.

Today I trade a portfolio of individual stocks and I have a passion for building automated trading strategies and systems.

What is your trading style?

I use a semi-automated strategy to trade stocks on an end of day basis. I look at both fundamental and technical analysis and use strategies that are based on historical simulations. I combine those strategies with my own experience and discretion to come up with trades that I believe are the most attractive on a risk/reward basis.

Mean reversion or trend following?

I have found that traditional trend following methods do not work as well as they once did. My methods are based on my own observations on the market whether they are based on momentum, trends, mean reversion or anything else.

Who taught you how to trade?

My mentor was a former head of trading at a well known German investment bank. I have also read and studied countless books, journals, and articles, and have spent many hours in the market. You can never stop learning.

Why did you make this course?

To educate others so that they don't make the same mistakes I made. Learning to trade can be a very expensive and drawn out process. As a trader, it is also extremely beneficial to have sources of side income as that takes the pressure off your own trading. Putting what I have learnt into a course also solidifies my own learning.

What are the secrets to successful trading?

First of all, you must have the passion to succeed. If you are in it only for the money you will have a very tough time and will be doomed to failure. You must also be comfortable with risk and be able to separate your emotions from the money.  Having a system with a profitable expectancy is also crucial and for that you will likely need a strong ability with numbers.

Why do most traders fail?

Most traders start off under-capitalised and then chase unrealistic returns which results in them blowing their account after a couple of big losses. Most beginner traders do not realise the realities of trading which is why they have trouble sticking to trading plans and dealing with their emotions. Trading should be treated as a business.
