These new Morningstar quantitative ratings are hot garbage.

I’m getting negative scores for managing 10 funds and having $0 invested in my own fund.

Neither of those are true.

The fact this was released tells me M* still doesn’t realize the influence it has on the industry.
And that’s despite the fact there are papers documenting that changes in Morningstar’s rating methodologies have literally changed the very structure of cross-sectional returns in the market.

That’s POWER.
“But Corey, your SAI says you don’t have any money in your fund!”

First, I am an owner/operator. Different situation. Second, maybe I have it in another vehicle.

But I don’t. I literally have it in the fund. It’s just that the SAI is updated ANNUALLY.
“But we’re just working with the data we’ve got!”

Great. So you’re providing ratings using incorrect data.
This isn’t some unknown little website.

This is Morningstar. Morningstar is a behemoth.

Launch a fund and see what happens if you ever fall to a 2-star rating. You’re done. DONE. At least for the next 12 months.
"With great power comes great responsibility.”

Act like it, Morningstar.
And unless you’re suffering from Gell-Mann amnesia, you know it’s not just these new ratings that are now suspect.

“Why does it matter?”

Because allocators look at this stuff.

Worse, their clients look at this stuff. Lots of time it just shows up on their quarterly statement. (It shows up in my Schwab account.) And they don’t know any better.

So you get a bias driven by M* ratings.
“Corey, why don’t you just contact M* and tell them the data is wrong?”

First of all, I shouldn’t have to.

Second of all, this is all hidden from me because I won’t pay M* for it. The only reason I know is because a friend sent me mine.
So the only way to know if their rating on my fund is wrong is to pay them $10k/year, or whatever it is, so I can even see it?

Okay.
I wonder if Morningstar analysts have skin in the game.

Where are the numbers about how much of their own money they put in the funds they rate highly?

@JasonMutiny A few graphs and charts you’ll see:

Consumers have a lot of savings and are feeling pretty wealthy right now...
@JasonMutiny Real goods spending has recovered, but services not so much.

So is the consumer WILLING to spend, they’re just not being allowed to?

1/ I received a DM this morning asking me about "recommended reading" in the space of trend following.

This all depends upon what you're looking for and your expertise, but I figured I'd share some thoughts publicly...

Interesting little anec-data…

Taking current ARKK holdings...

I went back to 1/29 data and found implied vols for 100%, 90%, and 80% moneyness on top 15 holdings.

I also found ARKK’s IVs for 100%, 90%, and 80% moneyness
2/

Normalizing the top 15 weights, you can use this data to back out an implied correlation.
3/

Here’s the weird part…

The implied correlation was basically flat (at around 62%).

In other words, the market was saying, “if this basket falls, we don’t think underlying correlations will go up."

1/ As I watch the basket of retail favorite equities and BTC make new highs into the end of the year, I can only hang my head.

Because my performance was absolute rubbish this year.

What went right? What went wrong? Read on. 👇
2/ I should start by saying that my core mandates have historically sought to participate with equity market growth and preserve capital in equity market declines.

They embedded three key tilts:

1. Trend
2. Value
3. Size

(You can probably see where this is going...)
3/ Value and Size have largely been "unintended" byproducts of our portfolio design.

Specifically, we applied trend-following signals within an equally-weighted portfolio of equity sectors (e.g. Tech, Financials, Health Care, Staples etc).

Watching WW84 and somehow turning a jet invisible makes it invisible to radar?

And then it's also magically the 4th of July just so they can fly through fireworks?

This movie is really, really bad.
WHERE DID THIS GOLD ARMOR MAGICALLY COME FROM?!
WHY DID IT JUST JUMP FROM THE 4TH OF JULY TO CHRISTMAS FOR NO REASON?!
