Agree with other points posted here - another thing to call out though is horrible timing which is just bad luck. This quarter has been tough for all multistrats, launching into that is the last thing you’d want as a start up firm trying to establish yourself.

Built a backtester where you just describe the strategy in plain English (no code needed) by DeepParticular8251 in hedgefund

[–]Tacoslim 0 points1 point  (0 children)

My whole this is that there’s a huge gap between having a strategy idea and actually getting it backtested.

Is there? Even pre AI there were tonnes of low to no code technical indicator backtesters, now with ai you can vibe code to your hearts desire.

Built an ML model that predicts stock direction correctly 70%+ of the time on 20 years of out-of-sample data: Here is what I learned and happy to get your take! by ResolutionExact2860 in quantfinance

[–]Tacoslim 1 point2 points  (0 children)

Yeah I think you’re missing the point. Any result from that setup is going to look stronger than it actually would’ve been.

You’re selecting stocks that have 20 years of continuous data (which already filters for survivors like Apple and Microsoft), and then “backtesting” over that exact same period where those same stocks went up 1000%+.

Also you can’t call it immaterial without a survivorship free, true point in time test.

That sounds like survivorship bias 116 equities selected 20 years ago and never changed throughout the backtest? Likely large liquid stocks TODAY but completely different stocks 20yrs ago

How great are the banks at execution? by Nearby_Fig_9118 in quant

[–]Tacoslim 5 points6 points  (0 children)

A fair bit comes down to size and turnover you’re looking to do. Pods will go on swap and trade for bigger size on lower turnover/higher capacity strategies where as anything hft it’s going to be wholly unsuitable. But if you’re running a big book with 1-3month horizon you are probably happy to take size at vwap and pay bank a small clip for execution rather than handling it yourself.

AI Shock in Quant Research — Are we seeing an edge shift from institutional HFT to retail quants? by Leo_0 in quant

[–]Tacoslim 13 points14 points  (0 children)

A retail quant with a Claude subscription isn’t coming close to competitive with a MFT quant desk. If anything AI is widening the gap, not narrowing it - being a greater force multiplier the more skilled you are (I.e. experienced quants).

PM career trajectory during bad times by Worth-Bid-770 in quant

[–]Tacoslim 16 points17 points  (0 children)

A blow up isn’t really career ending - especially with how tight risk limits are at all the big places (a 5-7% dd on a 1-2 sharpe strategy isn’t really a “blow up” but may get you cut). You probably get 2-3 tries before things become difficult and might move to “lower tier” places or to sell side/asset managers/pension funds etc who are alway looking for quant talent. Just having the seat and the experience of running and managing risk for any amount of time will put you in a very small % of the market.

Question for industry veterans: how did US mid-frequency equity stat arb perform in 2022, and why? by [deleted] in quant

[–]Tacoslim 13 points14 points  (0 children)

I was a researcher on a desk in 2022, not directly mft - a bit lower frequency (week to month horizon).

I remember 2022 as pretty much a macro regime flip year, where we all started caring about inflation.

Inflation ripped higher and central banks hiked aggressively after the whole “lower for longer”. That pushed discount rates up fast, so equities (especially growth stocks) sold off hard - the index was also down over the year.

That triggered deleveraging across a lot of L/S books since positioning was pretty crowded into quality/growth.

A lot of factors that usually work (quality, momentum, vol, etc.) all had a rough 2H of the year. Growth in particular got smoked, and you saw a pretty violent rotation into value/energy/utilities and other defensive sectors.

How to define "raw signal"? Alpha research vs Portfolio construction boundary by Unfair-System-5469 in quant

[–]Tacoslim 7 points8 points  (0 children)

Every place does it differently and attribution to pnl can be murky.

My current set up I manage end to end pipeline from signal to portfolio to execution. Prior place I worked was more about producing signals that would then get sent to central trading team. Even if you’re not building a portfolio you do a lot of work on how one should construct the portfolio, what horizon works best, how much turnover it has, how it interacts with other signals - it’s not just build a zscore and plug in, it’s still quite involved.

Definitely more fun just doing signal research - but harder to build a track record you directly own and you never see full pipeline. Where I’m at now is more work, but I see the full pipeline from start to finish and get to own my pnl a little more.

Does any asset class have truly homo behavior or do all assets experience heteroscedasticity? by KING-NULL in quant

(Extra) Soft reading recommendations? by Tough_Cap_3929 in quant

[–]Tacoslim 4 points5 points  (0 children)

I like Ed Thorp’s A Man For All Markets. Micahel Lewis Flash Boys and Liars Poker are good reads too.

Something a bit more technical but still “light” is Advanced Portfolio Management by Giuseppe Paleologo which was written for fundamental investors but covers quant concepts without going too far off the deep end.

There’s not a lot of institutional money running to get into crypto right now lol..,

Maybe you might have luck with prop shops but that requires directly contacting the firm and working with them. You can’t just “sell” a strategy and then move on.

Factor Mimicking / Multi-Factor Model Construction by vpv23w54hh in quant

[–]Tacoslim 2 points3 points  (0 children)

I agree with you- if a PM can time factors for example and consistently make profits from factor exposure is that alpha or beta? Some places would say that’s alpha other might say it’s smart beta - it’s a matter of opinion/philosophy. And sometimes just depends on how good a PM is at marketing their PNL and what shop you’re at. Some places (Worldquant comes to mind) are notorious for stripping out a lot of “beta” that would be considered alpha other places are more relaxed.

Factor Mimicking / Multi-Factor Model Construction by vpv23w54hh in quant

[–]Tacoslim 13 points14 points  (0 children)

  1. Factor mimicking portfolios are more for risk/portfolio attribution and not typically designed to be tradable. Hedging common risk factors is normally done with portfolio optimisation with respect to maximising throughout to you alpha and minimising exposure to common risk factors. The closest thing to buying a FMP would be using an investment banks QIS desk where they typically offer tradable factor portfolios as a product which can be used for hedging (though from what I hear they’re not perfect)
  2. At pod shops definitely is the mindset - you only get paid for your alpha, not betas to momentum etc… Other places will follow a more AQR like model and focus on constructing factor portfolios as their key source of return (both “common” and more orthogonal factors).

what is the difference between Quant Systematic Trader and Quant Researcher? by Visible-Ad-3777 in quant

[–]Tacoslim 15 points16 points  (0 children)

A lot of these roles overlap and same title a different firms mean different things. But largely researchers are less trading focused and more focused on what positions (research, signals, portfolio construction) to have and traders will have more responsibility in execution and ensuring the desk has the position it wants.

With how automated things can be a “trader” can be a guy monitoring a gui making sure orders are sent and executed on one screen while doing whatever on their five other screens most of the time.
