Circle of Competence 101

Warren Buffett and Charlie Munger often reference the importance of knowing the boundaries of your circle of competence.

But what is a Circle of Competence and how does it work?

Here's Circle of Competence 101!

1/ First, a few definitions.

A Circle of Competence is the set of topic areas that align with a person's expertise.

If the entire world of information were to be expressed in a circle, an individual's Circle of Competence is the small sub-circle that represents their expertise.

2/ The idea surfaced in the 1996 BH annual letter.

"You don’t have to be an expert on every company...you only have to be able to evaluate companies within your circle of competence. The size of that circle is not very important; knowing its boundaries, however, is vital."

3/ A Circle of Competence is built over time.

It is built through experience, reading, dedicated study, and effort.

It is dynamic, not static.

It can expand as you deepen your knowledge in new areas. It can contract if you fail to nurture your existing areas of expertise.

4/ To engage this mental model in your life, there are two key processes to go through:

(1) Identify what falls within your circle
(2) Identify the boundaries of your circle

(1) is all about figuring out what you know, while (2) is about humbly admitting what you don’t.

So we had discussed a few pointers in the previous thread about options,its time now we discuss further implications and applicability in this thread which will help you in NEW YEAR.
Let’s go and dive into the world of options trading.

-The amount of decay can be measured by theta. This is why you can be right on stock price direction and still lose money. The time decay portion of the option price overpowers the directional move in the underlying stock price.

-During result days due to the heightened uncertainty, there is opportunity for options sellers because of the expensive premium. When entering into an earnings trade, it is optimal to initiate the trade as close in time to the event as possible.

-Keep some cash on sidelines. This would help in adjustments,margin expansion,face losses and also during new opportunities which suddenly arise. A lot of people do the mistake of going all in and regretting later.

-Everything in trading has a trade off.

Unlimited profit comes at the expense of low probability of profit. Give up some profit potential, and you gain a higher probability of profit.
-By using portfolio beta weighted delta, you can accurately gauge your overall portfolio risk. If your portfolio is leaning too far in..

So what will be the aftermath of this GME event?

These are simply my guesses, I don't actually know.

Wallstreet will likely push for licenses being necessary to trade, or put more limits on how many trades you can make, or some other way to screw the average person trading. 1/

FYI, you can only make 4 trades in a day, but if you have more than $25,000 in your account you can make as many as you want.

The system is rigged against the poor, and weighted heavily in favour of the rich. 2/

Will the government shut down the market?

It's possible, but I doubt it.
It would open up new precedents and the optics would be terrible- i.e. shutting down the market because greedy hedgefunds fucked up, and normal people are taking them to the cleaners. 3/

If the government gives in to Wallstreet, they lose all credibility, because this story is basically David vs Goliath, where the Reddit guys are the good guys, and the hedgefunds are the bad guys.

4/

Likely they will implement similar rules to Europe, that stops naked short selling.

Anything more than that, I'm not sure.
I think the media will push the threat of the government shutting down trading, in order to scare people into selling, to give short sellers a way out. 5/

How position sizing can affect your trading performance-

Assuming that you are trading a Trend-following system with Big RR and low win-rate.

For example, assume that you risk one percent per trade on a 100,000 account
and you have 20 straight losses.

That one percent is of your remaining equity and at the end of 20 losses, you would be down to 81,790.60.

Now if you got a 30R winner and you are risking one percent of your balance of 81,790.60, your new equity would be 106,327.9,

You’ve had 20 losses and one winner though you are still up 10Rplus your equity is up by 6.3R percent.

Now, let’s say you risk five percent per trade on your balance. At the end of 20 straight losses, you would be down to 35,772.89 or down 64 percent.

If you risk five percent on this amount and get a 30R winner, you would be up to 89,621.48. You are up 10R, but because of your position sizing, your equity is still down over 10 percent.

This is why position sizing is the most important factor in trading if you get it right and you have an edge, you will do good.
