This Burry chap seems nice...
And, is it just me, or is getting absolutely balls long a concentrated hugely negative-carry bet written and marked my a more powerful counterparty, essentially a masterclass in how NOT to trade?
If I were Burry then, instead of having a cringe boomer Twitter meltdown, I would simply put on some My Chemical Romance, do some blow with some goth hookers, and blow off steam the old-fashioned way.
That's probably enough internet for today... 😂

you can still get away with dead simple trades if you pick the right place to do them.

i'm going to show you how to do basic white girl pairs trading in crypto perps. Image
like everything i share, it’s going to be very straightforward.

i’m not going to ask you to do anything cerebral or difficult.
you just need to:

1. understand what drives the divergence / convergence pattern we try to harness in a pair trade.

2. look for places where that is likely to be the case.

3. check that you actually see that behaviour in the past.

4. bet on it - in a simple direct way.

pairs trading for dickheads

when an online “kwant trader” starts writing about pairs trading i usually want to stab myself in the dick.

but, since i am both an enormous hypocrite and a better writer than the rest of you, i am going to talk about pairs trading today. Image
i’m going to tell you what pairs trading is.

and why and when it works.

and why and when it doesn’t work.

we’re going to run through a simple example. and i’m going to give you everything you need to trade it yourself, with nothing more than tradingview and a pair of hands. Image
actually, one hand would be fine.

i have a lot to say about this.

so do yourself a favor and read it all here: robotjames.substack.com/p/pairs-tradin…

a chat today reminded me that the crucial first step in any successful trader’s journey is to…

stop doing really dumb shit.
if you have no edge (and i think we can both assume you won’t at the start) then there’s nowhere for returns to come from.

you can’t make money like that

but there are plenty of ways you can lose money.
1) if you have no edge then every trading approach apart from doing nothing can be expected to lose money.

trading costs money (from fees, spread, and the price impact of your own trades.)

one of the most important things i tell people over and over again, like a stuck record, is that their trading should look like a useful thing that sucks.
you know that there are extremely sophisticated trading firms out there with ultra-low latency infrastructure and sophisticated modeling techniques.

and you might reasonably ask how you, as an individual, could possibly compete with that.
and the answer is that you can’t.

but you don’t have to.

you shouldn't even try.

so, why then, can many small speculators do ok and make money?

nearly everything that is a good repeatable trading idea looks like:

"under <some circumstances> this thing is likely to be too cheap/rich because <some people> are being forced or greedy or stupid... so the thing is more likely to go up/down in the future" Image
your job as trader, operating in an efficient, competitive market, is to tell yourself that your idea about that is probably bullshit.

and quickly prove to yourself that it is indeed bullshit.

destroy those hopes and dreams quickly... and move onto something more productive. Image
you can show that something is a BAD idea way quicker than you can show yourself that it's a good idea.

and showing yourself quickly that something is a bad idea is a GOOD thing...

all active etfs are trash.

under the premise that all active etfs are trash, i looked at what it would look like if you could shorta bunch of them against an equivalent SPY long.

the legs are sized to equal volatility based on 120 day rolling realized vol. Image
highlighly scientifically, i looked at etfdb and picked 15 active / tactical ETFs based on their name and category. Image
here's the performance of the long SPY / short ETF pairs individually.

some did less bad than others, but all the ETFs underperformed SPY, risk-adjusted.

FIG, HFND, MOOD look especially bad. Image
