7 lessons from 12 full-time investors:

On their research process, mental habits, and time management.

What they have in common:

- full time, private investors
- manage their own $$
- independently wealthy
- started with small capital base

A THREAD:
1. They make their own notes

They write things down, even if they never read them again.

Because the magic of making their own notes lies in the process of doing it.

Not in the actual notes themselves.

Making notes helps them discover what they really think about a company.
From Vernon, one of the private investors in this study:

“The notes help me to maintain mental consistency over time.

They are a stabilising influence when some news comes out which might tempt me to trade impulsively.”
2. Use of message boards

Several (but not all) of these investor use online message boards and forums.

Being a private investor can be a lonely journey.

So they bounce investing ideas and network on these forums.

But it's not just a cure for loneliness...
Typing their ideas publicly forces them to elaborate on their arguments.

This helps the knowledge "stick".

The more they explain something in their own words, the more connections they create with their prior knowledge.

So they can remember it for a longer time.
3. Think in terms of return on time invested

The scarcest resource for successful investors is not money, but attention.

For every action they choose to take, there is a trade off.

So they ask themselves this question:

"What can I choose to neglect and overlook?"
This forces them to hone in on what is truly important.

It increases their return per unit of time.

“Time is a limited resource with strongly diminishing returns.

The first hour you spend researching a company is much more important than the tenth hour."
4. Aware of their biases

The best investors know how to balance defence and offence.

They know when to stop researching an existing position, and move on to another company.

New information may make you more convicted...

But it doesn't always make your judgment more accurate.
A quote from an investor in the study:

"Many investors are management groupies.

They spend too much time on their favourite companies, posting on bulletin boards and going to AGMs.

They are squandering time which would be better spent looking for new ideas."
5. The goal of research is NOT to know everything about the company

Every investigation has a time opportunity cost.

Your aim is NOT to check all possible hygiene factors.

But to check enough to reduce your error rate to an acceptable level.
Psychological research suggests:

In many contexts, decisions are best made with no more than 5-7 points of information.

Any more information beyond that does not significantly improve decisions.

It may even degrade them.
6. They focus on what's knowable AND important.

Buffett talks about this.

In investing research, there are 2 types of information:

- Important
- Knowable

Focus on the intersection of BOTH.

You don't need to know everything about a company to make money from it.
“Focus on things which are knowable:

That is, things where research can plausibly give you superior insight

For example, the microeconomic advantages of a particular company.

Ignore things which are not knowable, for example, general macroeconomic predictions."
7. They search for truth, not agreement

An investor’s thinking should be focused on a search for the truth, rather than supporting prior affiliations.

The best investors seek for disconfirming evidence.

Do not allow where you sit to determine how you think.
From a private investor named Bill:

"It's always easy to think of reasons to buy a company. That is what most tipsters do.

To make good decisions, you need to look actively for reasons not to buy a company.

And then invest only in those where you can live with those reasons"
The above lessons are taken from this book, Free Capital.

It covers the mental habits and practices of 12 private, full time investors.

If you've always wanted to know how a full time investor spends his/her time...

How they think...

What they struggle with...

3. Think in terms of return on time

4. Aware of personal biases

5. You don't need to know everything about the company

The 3 part equation to make $$ from individual stocks:

$$ = % returns x Position size x Time

A short thread:
Many people only focus on the first part:

% returns.

They forget that results are also determined by:

- how big your positions are sized

- how long you hold the stock for

Here's 5 reasons why this equation helps you become a better investor:
1. Prevents you from chasing growth blindly

When you realize that % returns are just one part of the equation, you start to ask this question:

"How long can this growth sustain?"

Having that in mind will make you think twice before you buy the next hot stock.

Anyone can learn to speak well in front of a crowd.

You don't need to be smooth.

You just need to think like a Data Scientist.

Here's my secret after the last 9 years of speaking on stage to over 10,000 participants:
Before we begin, a quick overview of what I'll share:

1. a short story of how I learnt this

2. how I apply this to my own speaking

3. how you can apply this

Let's go:
1. Quick backstory:

I learnt this from the field of standup comedy a few years back.

And it changed the way I operated.

In my quest to hone my speaking abilities, I spent hours studying standup comedians. I would watch their shows and listen to their interviews...

My favourite quote from Sam Walton, Made in America:
"Sometimes I'm asked why today, when Wal-Mart has been so successful, when we're a $50 billion-plus company, should we stay so cheap?

That's simple:

Because we believe in the value of the dollar.
Every time Wal-Mart spends one dollar foolishly, it comes right out of our customers' pockets.

Every time we save them a dollar, that puts us one more step ahead of the competition—which is where we always plan to be."

I turned 31 last month.

10 years ago when I was 21, I had less than $1,000 in my bank.

If you told me I would be financially free before 30, I wouldn't believe you.

But it's not all about $$.

Here's 18 lessons I've learnt about habits, happiness, life and death:
1. Wake up early

I learnt this 4 years ago after listening to Jocko Willink.

I’m not a morning person. Until now I'm still not.

But I force myself to rise early most days.

Knowing you’ve accomplished more than others by the morning is a good feeling.

It sets you up right.
2. Lift weights

Everyone in a competitive field should engage in some form of intense physical activity.

For me I lift weights 5-6x a week. But it could be any sport.

It teaches you valuable lessons like:

- showing up consistently
- putting in the reps
- pushing past boredom

Discover how 2 billion dollar fund managers make investing decisions.

Meet David Poppe (right) and John Harris (not in photo).

Their firm, Ruane Cunniff & Goldfarb, manages the flagship Sequoia Fund.

They shared 5 of their key investing principles.

Here's the breakdown:
1. It's all about people

They believe there's a difference between good and excellent managers.

Their goal is to find the latter.

Because great management teams make better capital allocation decisions.

So in the long run, it makes the investment more predictable.
1b. How do they assess their managers?

They like to ask this question they learnt from Buffett:

"If you had to leave $1 million with somebody for 5 years, would you trust them to be a fiduciary of your investment?"

If the answer is yes, it helps them sleep better at night.

How to read an Annual Report in 1 hour.

A step by step guide for busy people:
Context:

This is NOT the best way to read an annual report.

It's just how I do it with limited time, while holding my 9-5 job.

I will use "10K / Annual report" interchangeably.

I'll also share some other great guides to reading a 10K at the bottom of this thread:
1. Be clear on your intention

First, why are you reading the 10K?.

"Understanding the business" is a terrible answer. It's too broad.

You will end up reading passively.

Because you don't know what to look for.
