Given the immense interest in this #investment #process thread about how to get investment ideas, thought of creating a logical follow-up ๐Ÿงต

Given that I have an idea & some sense for valuation & growth, how do i construct a portfolio?

If you like the thread, plz RT.


First thing worth mentioning is that I am only describing my own process. Others can follow a different process which could work for them.

Opposite of a good idea can also be a good idea

Before understanding the process itself, it is important to understand the problems the process is being designed to solve for. What are the key hurdles or troubles I have faced in designing my PF.

Hurdles
1. At any given point in time (in the past) i have only known deeply about 5% of the listed universe in India, or lower. When I say know deeply I mean read an annual report, an investor presentation, a concall, understood why the business is how it is.

2. I only started my corporate life 4 years ago, so my pf size is small compared to yearly savings. This means that I need to deploy large incremental capital every year at least for next few years. This cant be a buy & track pf, this is a keep buying & tracking for a few yrs pf
what better way to start sunday than a #kilpest thread: a classic peter lynch pick & shovel investment for the diagnostics sector. If you like the thread, please retweet this tweet to help educate max investors. ๐Ÿ™๐Ÿ™


Before I dive into Kilpest, some words on microcap investing. Everyone **needs** to be aware of what they are signing up for.

Two interviews from @varinder_bansal sirโ€™s Omkara capital with very successful microcap investors (one with @iancassel sir: https://t.co/WDSOOIcUn8 ...

@iancassel & one with @hiddengemsindia sir: https://t.co/iC8iKOsKWz) do a wonderful job explaining all the landmines & things to keep in mind. Do watch these, please before you buy any #microcap

@iancassel @hiddengemsindia My own take is that one has to create a diversified PF of uncorrelated microcaps (if you'd typically invest in 5, make it 10 and so forth). Understand that liquidity risks will always remain.

Get a cup of coffee.

In this thread, I'll walk you through 2 probability concepts: Standard Deviation (SD) and Mean Absolute Deviation (MAD).

This will give you insight into Fat Tails -- which are super useful in investing and in many other fields.

Recently, I watched 2 probability "mini-lectures" on YouTube by Nassim Taleb.

One ~10 min lecture covered SD and MAD. The other ~6 min lecture covered Fat Tails.

In these ~16 mins, @nntaleb shared so many useful nuggets that I had to write this thread to unpack them.

For those curious, here are the YouTube links to the lectures:

The first thing to understand is the concept of a Random Variable.

In essence, a Random Variable is a number that depends on a random event.

For example, when we roll a die, we get a Random Variable -- a number from the set {1, 2, 3, 4, 5, 6}.

5/

Every Random Variable has a Probability Distribution.

This tells us all the possible values the Random Variable can take, and their respective probabilities.

For example, when we roll a fair die, we get a Random Variable with this Probability Distribution:

Even asymptomatic, previously called healthy, people are tested (en masse) in this way, although there is no epidemiologically relevant asymptomatic transmission. This means that even healthy people are declared as COVID
