Fuck it! Aim to fail.

Go out there and do things!

And fail.

Fail once.

Fail again.

Fail so many times that no one has ever failed before.

Become the fucking expert at failing.

Fail better.

Fail in a way that you haven't failed yet.

Fail faster.

Surprise yourself and fail in a way that you didn't expect to fail.

Make it all about failing.

Write a detailed plan to fail and stick to it!

Every damn day.

Every day you should be getting closer and closer to failure.

If you're not - you're not fucking doing anything!

And that's the problem.

Do something!

And fail.

After you fail so many times that you are absolutely tired of failing - stop.

Take a breath.

Think it over.

Start from the beginning.

Start from a fresh page.

And fail again.

But do start in the first place!

You cannot fucking fail if you don't start!

Only when you start, only then you can have a chance at failing.

Pursue that chance.

Make the most of it!

Don't ever let a good opportunity to fuck up miserably go to waste.

Savor it and make it happen.

Fail.

And only when you lose count of how many times you failed...

Only when you failed so many times, you're literally sick of it...

Only when you cannot possibly think of any other way that you can fail and YOU STILL KEEP TRYING...

Only then you might get unlucky.

And you'll fail to fail.

$500,000,000.

Half a billion dollars.

Currently, this is how much of $SPX index needs to be bought or sold for every 1% down or up move, respectively.

These flows are a result of a substantial options trade that was placed yesterday.

Let's have a look at what's going on 👇

Once upon a time, there was a certain bank that shall remain unnamed.

This bank has an Asset Management unit.

One day, they embarked on a noble mission to help investors who might be concerned about a market correction.

Since many investors are, it looked like they could offer an attractive product.

And so, they launched a fund.

Catching up on the markets today, after a 2-week video-making blackout.

Here's what I gather so far:

• Energy prices up: Crude hit $80 per 🛢️, US Nat Gas highest since 2014.
• Energy worsens China's ongoing supply chain issues 👇

• China coal supply falls (China stopped coal imports from Australia in 2020), exports surged, power outages and restrictions common
• Supply chain issues fueling 🌍 inflation - US CPI is persistent around 5%
• Eurozone inflation released today came 3.4% (vs 3.3% est, 3% prev)

• Evergy crisis in the UK: UK Natural Gas futures highest for decades.

A new video! (phew, finally! 😁)

It was supposed to take just a day to produce, but instead took a week and a half!

Even though it's not the hot story of the day anymore, I really hope it was worth it and you'll find it interesting.

Video link in the first comment below 👇

I also wanted to thank these smart people for writing Evergrande Twitter threads below, which I referred to when making this video:

Forget what you hear on CNBC or Bloomberg.

It’s the options market that drives the $SPX price action.

Options became the new underlying and $SPX - the derivative.

Understanding the impact of options flows is vital if you trade the $SPX.

Let’s have a look at how they work! 👇

Meet Gary.

Gary is a market maker.

His job is to deal in $SPX options.

He makes it possible for hedge funds, pension funds, portfolio managers and other market players to trade their options against him.

He provides liquidity.

Oh, and he’s also a gorilla 🦍

And a pretty big one as well - quite a massive chunk of $SPX options volume goes through him.

After four years as a Quant in Goldman Sachs, I left this month.

In that time, I worked on 3 different desks across Fixed Income & Equities and completed about 20 to 30 different projects.

Here are the 9 non-glamorous things you should know about working as a sell-side Quant.

Of course, this is based on my subjective judgement and experience.

Every bank/hedge fund/coffee shop is different and might not necessarily share the observations listed here.

Nonetheless, many items did resonate with other Quants that I met throughout my career.

Let's start!

1/ Primary responsibility of a quant/strat is to help traders calculate prices and risks of their books correctly.

Modelling or developing comes second.

If a trader thinks the PnL or risks are wrong, that becomes the primary focus for someone in the team.
