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

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

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."

Caveats: the ARKK basket weights clearly aren’t constant and I didn’t use the whole basket.

(h/t to @TheSpeculator0 for pointing this one out to me)
5/

Further caveats: I didn’t even bother fitting curves here. I just used the IV of the nearest strike in BBG. I’m lazy. 🤷‍♂️

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?!

1/ Some random thoughts on the reflexive impacts of commoditization of access in finance…

In other words, “what happens when we make something easy to invest in?"
2/ In 1991, Goldman Sachs launched the Goldman Sachs Commodity Index (GSCI). By the early 2000s, commodity futures were an popular, emerging asset class for many financial institutions.
3/ Institutional investors were ravenous for exposure, and grew their exposure in different commodity index-related instruments from just $15b in 2003 to $200b by mid-2008.

1/ Having lots of fun convos in the DM’s about positioning of systematic players (and how that positioning changes w.r.t. spot, realized volatility, and time).

I think an important equation to keep in mind is:

dL/dV = -T / V^2
2/ If we assume leverage (L) is simply equal to target volatility (T) divided by realized volatility (V) (i.e. L = T / V), then we find that the change in leverage w.r.t changes in volatility is equal to the equation above.
3/ What does this mean?

Since T is pretty much constant, it tells us that leverage changes (i.e. buying / selling pressure) will be due to changes in realized volatility (duh).
