Irresistible to leave this moment alone - a thread to share some investment lessons:

1/ Size matters.
Melvin entered 2021 circa $12 billion in AUM and runs a highly levered balance sheet. That’s a lot of short exposure to move around if needed.

2/ WSB/Reddit captured a market inefficiency.

Stocks are not supposed to have over 100% short interest. Naked short selling is illegal. This set-up should never happen. Kudos to those who took advantage.
How it happened and what it means has rampant ramifications, but in this moment the individuals captured the anomaly.
3/ Be careful dismissing “in theory” for those rare moments when it becomes “in practice.”

Keynes said “markets can be irrational longer than you can be solvent.” I suspect this won't take down any significant hedge fund, but it definitely hurts.
3b/ Be careful dismissing “in theory” for those rare moments when it becomes “in practice.”

Academic finance teaches that “a short sale has unlimited downside and limited upside. Those events almost never play out, until they do.
4/ This isn’t the first drive by shooting I watched.

On the short side, VW stock in 2008.

And on the long side (leveraged), CMBX in November 2008

Both traded to completely irrational levels for a time. True left tail events for those in the positions.
5/ We don't know what will happen.

Peter Bernstein’s famous line about risk. A global pandemic leading to a soaring market? Negative interest rates? Online traders crushing monster hedge funds?

Beware those who think in certainties instead of probabilities. @AnnieDuke
6/ Timing is impossible

We know the outcome of this with near certainty (99%+ probability). GME stock will fall back to a fundamental level when the weighing machine takes over from the voting machine. We have absolutely no idea when - a day, week, month, 5 years? No idea.
7/ The short side is just brutal

My understanding is that Gabe Plotkin is one of the very best investors (process, not outcome). I highly doubt #melvincapital missed much in advance. And yet, here we are. No rebates, volatility, untethered trading - shorting is brutal.
8/ Size matters.

Melvin entered 2021 circa $12 billion in AUM and runs a highly levered balance sheet. That’s a lot of short exposure to move around if needed. And obviously, it's not alone in shorting stocks.
9/ 2nd order opportunities

Textbook hedge fund portfolio management is to deleverage amidst losses. Not just Melvin – this likely already cascaded to multi-manager platforms and will continue.
9b/ 2nd order opportunities.

Think about other places where deleveraging could take down stock prices and make attractive risk-rewards. I have my eyes on SPACs – large ownership from event driven funds, sold off yesterday across the board, and could get to cash value in trust.

Inflation is coming, inflation is coming!

Last month I wrote about the distinction between long-term secular inflation and shorter-term cyclical inflation

It has been clear for several months that we are in the middle of a cyclical rise in


The full thread can be reviewed here:


Today's PPI report should have been expected to surprise to the upside as the leading indicators of inflation have been screaming to the upside for months!

Here is the ISM prices paid index, cumulated into a growth rate

3/


Industrial commodity prices have also seen a major acceleration for months.

4/


So today's PPI report was in line with the leads, suggesting that we have a cyclical upturn in inflation that is * primarily concentrated in the manufacturing sector *

This is a key point.

I just finished Eric Adler's The Battle of the Classics, and wanted to say something about Joel Christiansen's review linked below. I am not sure what motivates the review (I speculate a bit below), but it gives a very misleading impression of the book. 1/x


The meat of the criticism is that the history Adler gives is insufficiently critical. Adler describes a few figures who had a great influence on how the modern US university was formed. It's certainly critical: it focuses on the social Darwinism of these figures. 2/x

Other insinuations and suggestions in the review seem wildly off the mark, distorted, or inappropriate-- for example, that the book is clickbaity (it is scholarly) or conservative (hardly) or connected to the events at the Capitol (give me a break). 3/x

The core question: in what sense is classics inherently racist? Classics is old. On Adler's account, it begins in ancient Rome and is revived in the Renaissance. Slavery (Christiansen's primary concern) is also very old. Let's say classics is an education for slaveowners. 4/x

It's worth remembering that literacy itself is elite throughout most of this history. Literacy is, then, also the education of slaveowners. We can honor oral and musical traditions without denying that literacy is, generally, good. 5/x
Nano Course On Python For Trading
==========================
Module 1

Python makes it very easy to analyze and visualize time series data when you’re a beginner. It's easier when you don't have to install python on your PC (that's why it's a nano course, you'll learn python...

... on the go). You will not be required to install python in your PC but you will be using an amazing python editor, Google Colab Visit
https://t.co/EZt0agsdlV

This course is for anyone out there who is confused, frustrated, and just wants this python/finance thing to work!

In Module 1 of this Nano course, we will learn about :

# Using Google Colab
# Importing libraries
# Making a Random Time Series of Black Field Research Stock (fictional)

# Using Google Colab

Intro link is here on YT: https://t.co/MqMSDBaQri

Create a new Notebook at https://t.co/EZt0agsdlV and name it AnythingOfYourChoice.ipynb

You got your notebook ready and now the game is on!
You can add code in these cells and add as many cells as you want

# Importing Libraries

Imports are pretty standard, with a few exceptions.
For the most part, you can import your libraries by running the import.
Type this in the first cell you see. You need not worry about what each of these does, we will understand it later.
