Compiling questions like this that don't have as many moving parts as say evaluating a stock would make for a good quiz for money managers.

Like if you give managers a quiz where the inputs were a given (kinda like a constrained game) would they even get the answers right?
Like how many people hand their money over to someone whose bet sizes would be way off even if you accepted the inputs they furnished themselves?

Reminds me of a tweet about whether discretionary or quant would benefit more from the other?
I think its discretionary probably has more to learn from quant as far as not screwing up the more straightforward aspects of investing.
(I'm not really sure to what extent or what proportion of managers are actually innumerate but i don't feel like scores on tests with known solutions would be comforting)

Mused about this in a post about how people think about risk

I'd like to believe that some semblance of market efficiency would weed out managers who would get basics wrong.

But "democratization" (snickers) means every gifted storyteller will raise an investment fund, there isn't much check on the testable forms of competence.
(investing ability is not something a test can find, but a test can find investing non-ability. You're bound to find incompetent people who have done well by sheer numbers + bull market, but that's what's known as a land mine)

The good news...
Basics can be taught, outsourced, hired for etc. A basic quant sensibility is a commodity esp relative to the other aspects of investing.

I'm curious about what folks think about the ability to be a good investor without being able to reason numerately in the 1st place.
not talking about PhD stuff...the Haghani experiment was simple coin flip bet w/educated people (insofar as an economics is a field of education. I was an econ major. You can ace that shit if you avoid the mathy route and are good at bs-ing in those blue-lined booklets)
Off to the gym, I'll check back later. Curious your views on this.

I ended up using @potion_so to point my MoontowerMeta subdomain to my public Notion pages.

If anyone is looking to get a website up quickly and is already using Notion, just point your Notion to a custom domain and the URLs can be pretty while Notion is your CMS.
I'll be adding tracking so I can get stats for these public Notion pages just like WP or any other CMS provides.

I've had a bunch of Notion pages public including the Volatility Wiki but now the URLs just look tighter.
The landing page I use for my Twitter profile acts like a custom linktree but I designed it in Notion:

Lots of new followers. Presumably option-curious.

A bit about me. I traded options on the floor for 12 years (8 at SIG, 4 with a backer). Mostly commodity futures and ETFs. Equities and indices very early in career.

Spent next 9 years a PM at a vol fund. Left trading in March.
I share stuff (non-alpha...more meta or basics that are less appreciated)

I'll put some resources in this thread for those that want to learn further:
My writing is hosted on my wordpress site MoontowerMeta. Blogs are chronological which is a crap format for this content so all my writing is indexed here.

Felt cute and looked at some nat gas options on CME's website.

Let's go on a little ride to talk about trade prospecting.

We are going to need some background...

The first thing to understand is the widowmaker spread in commodities is the famous H/J futures spread.

This was the football famously tossed between John Arnold's Centaurus and Brian Hunter's Amaranth.

@HideNotSlide did the story

The reason it's a widowmaker is because the spread can get unruly.

The March future, henceforth known by its future code (H), represents the price of gas by the end of winter when supply has been withdrawn from storage.

Protip

Scale price changes by implied vol and ignore noise.

Daily= change on day * 16/IV from yest

Weekly=change on week * 7.2 / IV week ago

Monthly= chg on month * 3.5 / IV month ago

Put your watchlist on the x-axis, enable barchart.
This is pretty much how I looked at all price changes. If the absolute value of any of the numbers was greater than 1 than the asset moved more than 1 implied standard deviation.

Set a filter for what size moves you want to see.

Clean way to look at how markets changed
This is what I call self-care

Portfolio Theory And The Invisible Option On Hobbies

moontowermeta.com/portfolio-theo…
I start with a recap from a short post I wrote last year that encapsulates a few timeless portfolio theory lessons.
Which implies a subtle point:

The value of an asset viewed in isolation is actually a floor.

Why?

There is an invisible option that lives above that floor.

Perhaps unpopular take:

It's a gambling hobby whitewashed as "investing".

The SNR is so bad that most "investors" in liquid names will never know if they had an edge.

I can save them them the anticipation.

They don't.

Their saving grace...
The vig is so tiny that they are playing blackjack for almost free. So the variance will swap the neg edge, encouraging winners to delude themselves that they are good at investing.

And from POV of giving the people what they want, it's working. Cheap casino.
Is this complex "blackjack" a good use of time? Probably as good a use a time as video games I guess.

If the entertainment we know as "markets" gets teaches you skills that's like getting comped by the casino host so much that you might come out ahead.
