"huge proponent of building own projects around the entire pipeline of trading if you're a qr or aspiring qr. often times you will be siloed into specific responsibilities (e.g. alpha generation data cleaning etc); personal projects round out the skillsets.

"Extremely large and successful podshops pass-through all costs to investors. They only hurt when there are a small number of large PnL generating teams that cannot offset a large number of losing teams. Then they would have to still pay the positive teams according to the formulaic compensation and this payment would have to come from retained earnings/treasury. Extremely leveraged long/short portfolios are in vogue right now (e.g. pod shops). They rely heavily on stops to manage risk. Could the failure mode be rogue wave short squeezes where things just gap up hundreds of percent in a single"

"Secondly risk limits exists not only on individual pods but as a firm as well. These risks are extremely well-distributed over a staggeringly large surface.

The probability of largewell-run podshops imploding from such undiversified carelessness is not zero but extremely minute"

"My favorite part of this is you calling schonfeld mediocre. That's how I know you're a player. Also I think you are talking about two different points here crowding in delevering/hedging and withdrawal runs. In crowded deleverings most firms now want PMs to be orthogonal to some custom crowding factors; but I feel that misses the point. Hedgefunds become correlated to each other during systemic events BECAUSE we are all trying to hedge to the same factors. 95% of risk models are a copy of Barra/Axioma based on Barra/Axioma or benchmarked to Barra/Axioma. When we see exposures and form hedging"

"I think really with any kind of automated signal research the most important question is how do you overcome the immense amount of noise in your signal pool. If you have some cause - effect you are looking for do you really need to automate the signal discovery Perhaps you could argue that you know the function but not yet the form. And if you don't then you are essentially data-mining which is not atrocious but it will introduce plenty of noise into your signal pool. How do you overcome that then becomes the principal question"

"Skill stones in Diablo immortal were so extremely inefficient when they were first released. They were a combination of some constituent fungible commodity e.g. skill_stone = skill_1 + skill_2 + skill_3. Hence the fair way to price a skill_stone would just be to do price(skill_stone) = price(skill_1) + price(skill_2) + price(skill_3). The catch was that there was no product or market for individual skills only skill_stones that were a random ensemble of skills. Firstly liquidity was so thin you could find a certain skill and buy up all the stones below a certain price (floor) with that skill"

"Something is interesting about multi-manager systems always opting to start with discretionary PMs in some cases even discretionary analysts (Norias).

Could you expound on this a little I wouldn't go as far as to say "risk factors drive crowding" but the idea that there is crowding from using the same risk factors seems fairly intuitive to me. If we are all looking at a certain factor when exposures to that factor rise we are all going to be shorting our exposure's worth of that factor to hedge. If we are using the same product - our factor-mimicking portfolio are going to be identical. There is going to be impact from this. Would this not be considered as crowding"

"I think something missing from this discussion is that 1) exposures are not constant 2) target portfolios are not formed instantaneously and we need to trade into them. 1) Exposures wax and wane.

As long as any two strategies share some common variation to a factor and that exposure increases beyond some threshold hedging is expected 2) If you residualizing your portfolio to F it will result in resid_port = curr_port + hedging_port This hedging_port is going to be in the same direction as every other strategy with the same common variation to F."

"Extremely large and successful podshops pass-through all costs to investors. They only hurt when there are a small number of large PnL generating teams that cannot offset a large number of losing teams. Then they would have to still pay the positive teams according to the formulaic compensation and this payment would have to come from retained earnings/treasury.

In crowded deleverings most firms now want PMs to be orthogonal to some custom crowding factors; but I feel that misses the point.

"What's the most intuitive explanation of factors that you guys know Every young quant (in a hf) is exposed to factors basically within [--] weeks into the job whether they are in a central training program or a pod. I find the mechanical explanation of a factor bland unintuitive and doesn't explain clearly the distaste for factors.

That captures the idea that 1) Factors are just another TxN weights matrix 2) Factors are basically spent alphas/signals"

"Taking a poll on behalf of a friend - A start-up fintech company has a novel idea at the end game it wants to crowdsource portfolio managers and allow thousands of people to participate in the upside of the financial markets while risking no personal capital. Here are the mechanisms: [--]. You first have to participate on their crowdsourcing platform to submit signals. These signals are very simple mathematical models that take about 1-60 minutes to create one. You are paid for each signal you submit. If the firm uses your signals in live trading you are paid a profit share on the PnL as well."

"It's a good read - at least worth thinking about for retail portfolios. For quants from my understanding I can summarize "return stacking": [--].

Add exposures to A1 that you do want. Use levered exposures for capital efficiency. They've combined [--] and [--] and called it "beta swapping". [--]. Combining [--] and [--] is "returns stacking".

"Playing POE2 and really liking the currency market especially as a market practitioner. In general every game that has a free market allows a patient speculator to profit either from trends or market making; but there is some nuance in every one of them. In POE2 the primary mode of exchange is a barter trade around valuable commodities like the one shown below. There is a currency market that facilitates this barter trade and it allows you to buy "5 exalts for [--] chaos". The most reliable method I've found so far to profit from the markets is to quote a spread around liquid markets (example"

"Guessing from a portfolio standpoint: If you knew with certainty (P=1) how the stock price of a single instrument will move tomorrow the rational optimal thing to do is to borrow from every outlet you can and bet the farm house and tomorrow's farm and house on it. The more certain you are the less you want to dilute that alpha. Even in the context of having [--] stocks with P=1 you would just pick the one with higher abs returns; in cases of complete information there is no need for diversification. However when P is small diversification becomes the only free lunch. Noise gets averaged to 0"

"Somehow I think the young white collars are underestimating how devasting AI is going to be in their job prospects. At least in the "short run" until we all become redundant. I foresee that the first tranche of jobs that are going to be impacted are the junior white collars that are traditionally the byproduct of being a median performer of a fairly technical degree (e.g. your 50th to 90th percentile CS grad). These median performers who would otherwise end up with jobs at SMEs with simple requirements for "run-of-the-mill computer jobs" will be the first to have their place in the economy"
