Market Worldviews - A thread on how I've been learning how to view markets
Disclaimer: This thread has no stock picks, strategies, or systems. I talk about learning how to view markets, but I don't even really explicate how I view them. That's because I'm learning and my views…
My $ETH momentum signal back in the positive.
Since mid-march, longest momentum drought in a while.
Last 2 instances were false positives, but noting that CT is quite exhausted.
Next few days should be interesting
So...what next?
These articles do a great job of teaching a worldview.
If you're interested in how this worldview could translate to taking risk - ie how to do what traders do, highly recommend these resources I'm currently sifting through

This article is hilarious and a great example of what trading is about.
@Gingfacekillah
talks about this all the time, but sometimes examples really bring things to life.
The article linked suggests (maybe) there is same-side reliability in coin flipping for (most) coin…
Finally building basic infrastructure to track transactions, performance, etc.
I've been really lazy about this, but just impossible to take things seriously and also not track performance metrics, slippage, taxes, etc
Obviously everyone on FinTwit is still here, but it's at least worth noting. The thing we're doing is hard and the act of doing it is making it harder to do. That's a really fucked up way to spend time if you think about it...
One easy way of getting around that is to not view…
Anyways, obvious disclaimer. This post is intended to be the thing I tell my friends I've been thinking/reading about.
I am the opposite of an expert. I have no strong views. I don't work in this field. I've never taken a statistics or economics class beyond the 101 level.

Well, I might be completely wrong and am very new to these concepts but...
If you take 5 assets, and you have a forecast for their means and covariances, and you use that to get a set of weights that optimizes sharpe....so far you haven't taken on correlation risk. You've just…

The more I journal, the more I realize how homogenizing social media is.
Removing from phone, restricting after 9pm, and setting a strict 20min/d time limit. Hoping it helps.
I do think I get a lot out of being here, but the downsides after a small amount of time are notable
Still prefer Claude to GPT4. Claude isn't lazy, it's more thoughtful, more prone to correct me in productive ways rather than just agree with me and push me in my current direction. GPT4 doesn't know when to use code v. intuition to do a thing yet.
@DakotasTwits
I honestly find your enthusiasm and energy so infectious and inspiring
Never stop dude, don’t let the world take that away from you
Keep that same energy
You are allowed to not have an active view
Just keep to a small survivable risk
neither buy nor short the move
If someone else says they have edge buying the dip, doesn’t mean you have to do the same
You’re allowed to just opt out and opt back in some other time
Lastly, if you're interested in how to think about worldview construction - purely epistemologically - as a philosophical problem....
(ie - why is this not arbitrary? Why this worldview on markets as opposed to another one?)
I highly recommend philosophy of science.
Ignore…
It’s an everything down day. Flattening VIX term structure… Hard to tell if we’ll get follow through, but this seems like real fear & risk re-rating. I think the cross-asset selling is jut broad portfolio de-risking
Ticker names is an easy edge.
A simple ticker strategy would have 10x'ed your return on S&P over past 5 years.
Example: Buy tickers that start in "N" and end in "VDA"
$VT is 5% from ATH, VIX is at 18. This isn’t a catastrophic panic, at least for now
But
It is fantastic practice even if it turns out benign. If you noticed the change in risk environment, adjusted exposures, etc here - bodes well for what you’ll do if panic does come
Mean variance optimization seems like a priced risk premia related to 'correlation risk' rather than getting paid for diversification through a behavioral inefficiency around leverage aversion
2. Market Efficiency isn't magical. It's cut-throat.
market efficiency comes from somewhere, intense competition between traders to buy cheap and sell expensive.
This means we can measure transient deviations of individual prices from fair value.
The deviations are transient…
3. The worldview on markets is scientific (as opposed to many, many approaches to markets which from a philosophy of science perspective could be viewed as pseudoscientific).
By 'scientific,' I don't mean this approach is perfect or magically right and we should always have…
This is a great case study of how not to quant
1. Identify why the analysis is flawed
2. Evaluate how you'd find and measure S&P seasonality
3. Learn how to communicate an effect clearly without misleading
Seasonality can be a legit edge.
This analysis, however, is silly.
Market seasonality is an easy edge.
A simple seasonal buy and sell strategy would have doubled your return on S&P 500 v.s. buy-and-hold over past 2 decades.
Example in chart: buy in Oct, sell in Jan, buy in Mar, sell in May, buy in July, sell in July. All buying are done at…
I am of the belief that all 5 of those resources take a unified worldview on how markets and knowledge in markets might work
3 things I really appreciate about their approach
1. Respect Market Efficiency
Methods these traders refer too often use current market returns of a…
Another $ETH whiplash.
Honestly, OK. To destroy the YTD profit, would have to take another 58 of these losses without a hit
Can I get a higher than 2% hit $ETH rate? I'll take that bet.
Key is to avoid big losses along the way.
Meanwhile copper position keeps running
My $ETH momentum signal back in the positive.

(Fwiw, the lack of probability education in medicine - where clinical reasoning is literally 'base rate they have pneumonia + updating on [new info]' is...unfortunate)
Approaches that ignore everything we've learned are a bit suspicious.
It's especially weird to watch people use Elliot Wave Theory to make bets on the dominance of AI, given the differences between the methods being used in the former and the latter...

Approaches that I often see amongst retail quants involve trying to re-invent science.
This is the case of the quant who after many experiments has created an 8 step method to backtesting without overfitting.
It's actually really admirable and comes from a great place. The…
systematics already de-risked to increased vol, but equity trend should mostly still be long due to longer lookbacks
(if) we have another 3% down move, they'll start dumping and we'll move to the 200DMA fast.
gonna punt 0.1% risk on this speculation in the name of learning
I think someone's systematically selling covered calls on $MSOS
I think $MSOS relative strength to index here is notable
I think I know nothing and am speculating wildly
Viewed this way, it's obvious how competitive it is. The process of making money from market inefficiencies is watching inefficiencies get more efficient.
That means if you're good at this and clear eyed, you watch your profit opportunity decay as you make money.
Imagine every…

What's your theory for why non-toxic dating apps are difficult?
Seems like 'incentive to keep you on the app' issue is a local minima - if you could reliably match, people would join app > leave app
But since it hasn't been done, I must be wrong. Just not sure why.
@LogicalThesis
Honestly, I view every drop relative to normal volatility. SPY typically moves 0.8% a day, and is down 5%. Lots of stocks that typically move 2-3% a day are down 15-25%
I don’t see a large divergence
In a drawdown since 4/3. Matches the biggest drawdown this year but very different.
The earlier drawdown was amidst high vol exposure to raging up trending crypto - was worth it, didn’t blink an eye
This drawdown is gradual fee burn from over trading. The slow death.
@TradetroniX
I think if you have 10 discrete systems, and you diversify, you’ll get benefit but not bc you’re diversified
It’s bc the edge is continuous, and 1 continuous system subsumes all 10 systems. But diversification amongst 10 binary systems approximates 1 continuous
Just my 2cents
@LogicalThesis
I think Jim Simons and Druck also won, but I think they were after Buffett?
Always a lot to learn from studying the greats, and yet every great made their own way
@NotQuiteMidlife
@BigBreakfastLob
Exactly - risk premia are also edges, but they're much lower sharpe bc they're so risky...
framed this way it's much less attractive unless you're a large wealth management fund and you're combining a bunch of low sharpe edges and need a boost
not worth it for a trader imo
Sometimes I'll place a sell order at the mid, and get no action
And then I'll move the order to the bid, and get filled at the mid
It's like they identified me as dumb money but then forgot to rip me off.
I must be losing somehow. Will collect more data.

@hkuppy
The adverse selection is real and needs to be overcome. But, for those who are selective - they get to select from prices set by less competitive traders, which is nice
@Vertox_DF
@pedma7
@lazy_jonas
Ya, if you’re gonna do apples to apples, find an equally inefficient part of equities. Small caps, illiquid hyped stuff, etc
@elhroz
in the single stock space, this can also apply. If 2 stocks have the same multi-factor score (inclusive of vol as a factor), the one with highest raw volatility gets you more capital efficiency
@nope_its_lily
Turnover would go down, but you could charge way more?
If you thought there was a 1/5 chance that this date would lead to me never using a dating app again, what price would you pay?
@BigBreakfastLob
Ya, I'm just dumb and got filled at an illiquid pre-market price that gapped to fair price immediately at the open.
Gotta be more careful with where I place my limits and more willing to not get filled
@BigBreakfastLob
Yup - like internal is Meta creating AI to stave off competition from someone else with a better AI based product; ie AI enabled persistence of status quo (just a lot of capital investment)
External is Llama3 automating some mundane job changing society in a genuinely novel way
@LogicalThesis
The best strategy is the one you actually implement right?
Ya twitter is weird, everyone tweets their takes and they have different time horizons and stuff. Fun to bounce ideas though
Lol learning that my quite small $SVIX position sizing was probably still (slightly) too high
Portfolio flat today is while maintaining modest risk exposure is more than I could ask for
@LogicalThesis
Ya I’m actually sorta playing a similar concept from the opposite direction? I cut all my crypto risk like a month ago and flipped into gold and copper (I think I got really lucky w the exact timing)
Sometime soon I’m going to need to flip back and that’ll define my EOY pnl
@stevehouf
Err but if you're not everywhere in the forecast area at once, doesn't this end up resembling the chance that it rains where you are? Which is what we assume the forecast is telling us?
100% confident that 30% of the forecast area will see rain...meaning 30% chance I see rain.
@marketplunger1
I remember seeing your post & thinking
"I trade a momentum model. I know CoT has some signal, but that's not in my model. My model with CoT would be better than it is now... and yet, I have a momentum model. Gotta stick with what I know"
Stuck with it, got lucky. So it goes.

@ZaStocks
Intuitively it seems weird to imagine analysts aren't assigning any value to Coinbase's crypto & VC assets when they're very not hidden, but honestly imo if crypto is running into COIN earnings, it'll probably pop
@Architect9000
Eh, markets tell you chances relative to prior positioning. Helps to have a model for prior and current risk tho to put market effect into context
Ie how much of Friday was pricing v crowding? Idk but it’s a good Q worth investigating

That's not the point at all. The point is when it gets popular, the assumptions of the backtest break
Simple thought experiment - what happens to forward correlation btwn 60/40 & trend if passive indexers all switch to $RSST & $RSSB to stack CTA on index exposure?
@EntropyChase
Ya seems right to me. And if you do that you tradeoff volatility for sharpe in the most optimal way...but then people take the optimized portfolio and lever it up to SPX vol (for instance), and I think that the excess returns that come with that leverage are the priced risk that…
