Unfortunately there's nothing new about this scam; it happened to one of my dad's friends 20 years ago. I think it's wise to treat anything you are told by a dental or healthcare professional with a healthy dose of skepticism as your interests are often misaligned.


Agreed, this scam is not new at all.

When you have doubts about your dentist's diagnose, just visit another one to get a second opinion.


Building algorithmic trading models. So far results continue to be good with every model outperforming the market on both absolute and risk-adjusted basis since going live.

Since launching https://grizzlybulls.com in January 2022:

Model | Return | Max drawdown

-------------------

S&P 500 (benchmark) | 21.51% | -27.56%

VIX TA Macro MP Extreme | 64.21% | -16.48%

VIX TA Macro Advanced| 59.13% | -19.12%

VIX TA Advanced | 35.20% | -22.96%

VIX Advanced | 33.39% | -23.93%

VIX Basic | 24.29% | -24.23%

TA - Mean Reversion | 22.30% | -19.92%

TA - Trend | 27.07% | -24.98%

This is an unleveraged, apples to apples comparison. These are not high frequency trading models. Most of them only change signal once every 2-4 weeks on average. During long signals, the models are simply long the S&P 500 and during short signals, they go to cash.

One of the pros of this macro swing-trading/hedging style is high tax efficiency, by holding a core ETF long position that never gets sold and then selling S&P 500 futures (ES or MES) of equal value to the ETFs against the long position. This way your account will accumulate unrealized capital gains indefinitely and you'll only pay tax on the net result of successful hedging. The cherry on top is that the S&P 500 futures are section 1256 contracts that are taxed at 60% long term / 40% short term capital gains rates regardless of the duration they are held.

The models use a variety of indicators, many of them custom built. Most important are various VIX metrics (absolute level, VIX futures curve shape/slope, divergences against S&P 500 price, etc), trend-following TA metrics (MACD, EMV, etc), mean-reversion TA metrics (Bollinger Bands, CMO, etc), macroeconomic (unemployment, housing starts, leading composite), and monetary policy (yield curve inversion, equity risk premium, dot plot, etc). They've been backtested very cautiously to avoid overfitting to the best of my ability.


I've been curious about doing algotrading for both the data engineering aspect and the quant. Do you have suggestions about books or others sources to get inspiration from ?

Is this a one man venture or do you have a group discussing edges ?


For inspiration, I highly recommend "The Man Who Solved the Market" about James Simons and Renaissance Technologies. Some of Ernie Chan's books are great for learning about the basics, but ultimately finding an edge is the most difficult part. Books can teach you some of the best practices for researching edges, how to avoid common pitfalls in backtesting, etc, but no book will ever lay out the details of any strategy that contains alpha of course.

Grizzly Bulls is currently a one man (and wife) venture :)


> Grizzly Bulls is currently a one man (and wife) venture :)

best of luck

ps: i was starting an ernie chan youtube binge watch, i hope i'm strong enough to follow :)


I've looked before for good online communities but never found one, I'd be interested if anyone has a source. The best people work for hedge funds so wont disclose anything and the individuals out there mostly are clueless or lucky, I suspect its too hard to find an edge without the resources of a large firm.


If so good why are you selling it as a service ?


I expect the long term CAGR for the top models to be in the 20-40% annual range. That's certainly high enough to get wealthy over a couple decades, or sooner if you are already starting with 8 figures, but it's not overnight Roaring Kitty style fast money. Grizzly Bulls' growing revenue helps even out my overall income, and I could definitely see it growing to $10M+ ARR over the long term, very significant even with a 9 figure net worth.

The models are not HFT. Swing-trading the most liquid instrument in the world (ES futures) has extremely high strategy capacity, well into the billions or perhaps 10s of billions, so selling signals does not (currently) in any way negatively impact my own returns.

The alternative would be to start a hedge fund, but that's an expensive and highly regulated endeavor that appeals to a different audience.


> selling signals

could this have any legal risks, e.g. your clients will sue you for manipulations and causing losses to them? Is this a valid business at all from SEC standpoint?


We have the standard disclaimers in the TOS. Essentially, Grizzly Bulls is not a financial advisor, offers no financial advice, and only sells access to signals generated by proprietary models, not the underlying source code for the models. How subscribers choose to use those signals is entirely at their own discretion. There are hundreds of similar businesses out there, and really signals are no different than buy/sell ratings published by more mainstream sites like Seeking Alpha or Morningstar.

All that said, subscribers have generally been happy with Grizzly Bulls' service as evidenced by our low churn rate, especially for the higher tiers.


It would make more sense to start a fund.


Could you explain why?


How would I even go about starting investing using this? Let's say I have a trading212 account or similar? Where do you even start? Do you have a "how to get started page" assuming someone knows little about investing.


https://grizzlybulls.com/how-it-works is the best page I have explaining the basics, but I probably need to be more accommodating to complete beginners. Grizzly Bulls is intended to be a great complement to the buy and hold passive indexing strategy that most people use.

The easiest way to use Grizzly Bulls is to hold VOO in any brokerage account, sell it when the model generates a sell signal, and then rebuy it when the model generates the next buy signal. A slightly more advanced but more tax efficient approach would be to open a margin account with futures trading permissions and sell S&P 500 Futures (ES or MES) of equal value to your VOO during sell signals, then repurchase the contracts you sold during the next buy signal. With this method, I've found you can usually reduce your overall tax burden to less than 15% and you'll only owe taxes on the net result of your futures trading.


Sorry for the total newbie question here -- I'm familiar with options and have traded them a little bit (though that was a long time ago). I've never traded futures before. With your "more advanced" approach, can you help me wrap my head around what the possible outcomes are of buying/selling the futures contracts? What is the impact to me if I, for example, hold $100k of VOO in my brokerage account, sell futures amounting to $100k total on a sell signal, and then I'm "called" (sorry, don't know what the correct term here is) on my futures? Am I wrong in thinking that I'd be required to cough up $100k or my VOO shares?


Good question - you won't be "called" or anything like that in this scenario as you are effectively market neutral. If VOO goes up, your ES/MES futures value will go down accordingly and your account's net liquidation value will remain unchanged and well above your maintenance margin figure.

The only way to really drop below your maintenance margin is if you are either leveraged long (i.e. more than 100% long) or short (i.e. less than 0% long), and the market moves significantly against you. In that scenario, your broker will automatically start liquidating some of your positions.


That makes sense from the perspective of my brokerage/margin account, thanks! I guess I was also curious about the futures themselves; since they’re a contract to buy/sell just like options, would I ever be required to take an action, assuming I’m holding the futures contract at expiration?


Oh no, you are never required to take an action with equity index futures as they are cash settled every quarter. So whether you have an open long or short position at expiration time, it will automatically disappear from your account with your balance left exactly as it should based on the settlement price.

However, this does mean that you'd need to open an equivalent position in the next quarter's contract to maintain your hedge, if one was open, at expiration time which is regular trading hours opening time on the third Friday of expiration month.


Got it! Thank you so much for the info. Interesting stuff!


The models use a variety of indicators, many of them custom built

Do you run it with good volumes or are these returns “as if”?


> Do you run it with good volumes or are these returns “as if”?

This trades the S&P 500. The SPY ETF along trades 21 billion dollars a day of volume. He'd probably need to trade a billion dollars to impact it.


Ofc, but as far as I understand algotrading, you don’t need to move a market for other bots to abuse your scheme eventually. Works on real non-toy money since 2022 and works on your napkin simulation since 2022 is a huge difference.


Depending on the market, that threshold can be crazy low. Many smaller brokers make most of their profit by playing against their "customers". Small players can't use the big brokers, and even if they become big players, this just attracts other big players to use their bots against them.

It's a dark forest out there.

Source: I knew several people starting out with a few hundred thousand, "doing really well", and then soon as they crossed some magic number like one million dollars they suddenly started getting front-run on every trade until they gave up. Two of them spent years trying to "fix" their algorithm until they finally figured out what was happening to them.


This basically confirms my concern. It’s known that algo doesn’t live long on sensible amounts. It’s a never-ending churn between bots who don’t even take you personally. It’s as simple as the N+1 guy learning (ml or human ideas) on the whole market that N is a part of and stealing profits from all n <= N by design.

If OP managed to run it live since 2022, I’d be very surprised and glad for them. If not, condolences for the time lost on napkin profitability.


Where are you sourcing your data from/what are you trading through?


I use Interactive Brokers for automated trade execution and as data source for real-time ES and VIX data. Data for the other indicators comes from a wide variety of sources. One of my favorites is https://fred.stlouisfed.org/.


Does your book have a digital version?


Not yet, but I plan to write a revised edition incorporating some of the feedback I've gotten in the near future. I'll include a digital version with it.


Do they work in non-bull regimes?


Yes, in fact non-bull regimes are where they earn most of their relative outperformance. During buy signals, it's impossible for the models to outperform as they are long the S&P 500. During sell signals, they are in cash with the hopes of rebuying lower (doesn't always work out as they are of course imperfect). When the market is rising with low volatility, there aren't as many opportunities for outperformance.


wont your strategies incur short-term cap gains ? so, they will have to outperform the S&P 500 index to account for it.

great start, and good luck.


Yes, but that's why the preferred method of implementation is using the S&P 500 futures (ES and MES) as the hedging tool during sell signals. With this method, you hold your preferred ETFs/stocks of choice forever and continue to accumulate unrealized gains indefinitely. Then on sell signals, you sell ES and MES of equivalent value to your long holdings to effectively go market neutral.

At the end of each year, you'll only owe taxes on the net result of your hedging with futures, and futures are section 1256 contracts so they are taxed as 60% long term gains / 40% short term gains regardless of holding period. In practice, I've found that this usually works out to an effective capital gains tax of less than 15% of annual profits. If a strategy returns a gross 30%, then the after-tax return would be about 25.5%.

Also, if you implement in a retirement account which many of our members do, capital gains are irrelevant.


You have a point, but it still makes sense to report before tax performance. Before tax performance depends on model only, but after tax performance depends on model and the user. this website couldn't report that even if it wanted.


I think most would agree $250k is a comfortable lifestyle, but if your neighbor is making $1M/year in the same profession just because he works at a different company, a bit of bitterness and or desire for more is hard to combat. Your neighbor can retire at 45 with $10M+, why should you be content with the low end of upper middle class and working until 60 for a more average retirement?


I don't disagree, just to your point about early retirement, be aware of what you really want vs just chasing comp. If it's comp, then it also begs the question of why not FAANG then.


This is exactly it. Chasing high salaries for many of us isn't about buying more expensive things. It's about obtaining freedom in your life as early as possible. Add in a family, and the only way to do it in your mid 40s when your body is still capable of doing anything, is to make numbers like what you mentioned.

A common retort is "stop working for FAANGs, then maybe you won't be in such a rush to get out". I completely disagree. I don't care who I'm working for, even if it's myself, it's the fact that my time is controlled by some outside force that I'm trying to escape.


It's a bit ironic that knowledge work will become obsolete before blue collar work. I disagree with the author that it will become completely obsolete in the next 20 years (although certainly in the next 200), but it will change significantly and there will be a massive downward pressure on knowledge worker compensation as the barriers to entry have been decimated. On the other hand, good luck getting your AI to unclog your sink, remodel your kitchen or fix your AC any time soon.


I mean if you think it a bit forward, if you really have a general system that can mostly obsolete all knowledge work, I don't think the leap to having some sorts of robots would be that many years away. These general agents could be taught to control the robots and perform different things, or they could even do that research by themselves. Also if most of knowledge work is gone, these people are either unemployed and have no money to spend basically or retrain to some blue collar roles which would push down wages if there is more supply of the workers. It's very hard to actually predict how it all will end up in that case


73 is less than a decade into retirement age; hopefully she has much more than a few! Looks like 14.5 years life expectancy


> Looks like 14.5 years life expectancy

And I assume that's for normal people of her age and gender? She's probably far from normal.


Tragic news; he was my personal inspiration for getting into algotrading and founding https://grizzlybulls.com. The ultimate counter-example to the Efficient Market Hypothesis. RIP


I've been building algorithmic trading models for the last 4+ years. After trading them successfully with my own capital for more than a year, I launched https://grizzlybulls.com as an alternative to the traditional hedge fund monetization path.

Since launching in January 2022, we've significantly outperformed the market with lower volatility and reduced max drawdown:

Model - Return - Max drawdown

S&P 500 (benchmark): +9.91% -27.56%

Platinum: +45.34% -16.48%

Gold: +39.53% -19.12%

Silver: +17.24% -22.96%

Bronze: +14.12% -23.93%

Vix Basic: +9.81% -24.23%

TA - Mean Reversion: +17.77% -19.92%

TA - Trend: +17.29% -24.98%

This is an unleveraged, apples to apples comparison. These are not high frequency trading models. Most of them only make a trade every 2-4 weeks on average. During long signals, the models are simply long the S&P 500 and during short signals, they go to cash.

Just popping in to say:

1. Love the name, not enough Pyrrhonists on hacker news these days! The OG.

2. Love the website, your design skills are killer. I hate that entire industry and even still my monkey brain went "oo I want to see the Euphoria index, sign up!"

3. This is kinda quintissential AI. Not to distract this thread from the valuable topic of non-trendy projects, but this is a great example of why we need to reclaim "AI" as a much more general term. I mean "algorithmic trading" could be a synonym for "human-like problem solving"...


Congrats on your success to date. I spent quite a bit of time putting together a trend system based on breakouts in futures markets. The system itself was nothing overly special. I purchased a few decades worth of futures data, created and backtested the system with Tradingblox.

The biggest problem was that the system really needed a minimum account of $1m USD so that each position wasnt too large and to get the diversification across different futures markets.


Real test is when you have a down market. Everyone one looks like a genius in a bull market


The parent comment says they launched in Jan 2022. Jan 2022 to Jan 2023 was a down market.


It will not last , my bet is on that, who knows if it’s attributed to luck or if the algorithm has solved entropy.


Good algorithms make the market more efficient, and this remark of yours about the future being unpredictable probably isn’t as great of a display of wittiness as you imagined.


This is nice to hear about. Can you tell me more about how your live results matched or diverged from your backtesting?

Did you list the returns of the commodities as a comparison, or are you trading those futures as well in the mix? (I know you only talked about ES/MES)


I've studied many systems over the years and never found any that matched or outperformed their backtests. So far our live results have hit between 1/4 and 3/4 of backtest performance depending on the model. Needless to say the high inflation and high interest rate market climate over the last two years hasn't been seen in the rest of the backtest period, but conditions are starting to normalize now.

Nevertheless, it would be prudent to expect any algorithmic trading model to underperform its backtest going forward, but there's enough leeway in the CAGR and max drawdown figures to underperform the backtest and still produce substantial alpha, especially for the more advanced models.

Right now the models are specialized to trade equities. I may develop new models that trade commodities in the future though.


Is it correct to say you need a multiple of 50x the value of SPY to execute this strategy (if the minimum you can hedge with is 1x MES)?


To implement the strategy in the most tax efficient manner without leverage you would want to have an account worth 5 * (S&P 500 futures price). Today that would be about $26,375. MES uses a multiple of 5 while ES uses a multiple of 10.

However, with today's $0 commissions, if you aren't overly concerned about taxes, you can try out this strategy with as little as $500 and simply buy and sell one share of the ETF VOO on signal changes. Alternatively, if you have the risk appetite, you can get started with trading MES futures with less than $10k, though caution should always be warranted when using any amount of leverage.


Very cool, thank you. Isn’t the notional value of ES 50x the future contract price (or 10x MES)?


exactly ES is 50x S&P 500 futures price or 10x MES, current value per contract is about $263,800


Have you retired yet?


78 seems so young to die. I suppose my family is lucky to have good longevity genes and disciplined enough to live fairly healthy lifestyles. I have 3/4 grandparents still alive and relatively healthy in the mid 90s and several great and great-great grandparents lived past 100 even at times when that was even less likely than it is today.

I do expect there's going to be some revolutionary enhancements to human longevity over the next century. Not as optimistic as Kurzweil, but perhaps the oldest old will shift from ~120 to ~150 and the median from ~78 to ~100


My father is doing poorly, and he is just around this "median" age. He has a chronic disease which somewhat contributed to him not moving around much. Largely sedentary, but not over-weight.

On the other hand, my in-laws are doing very well, into their 80's. They take walks, attend talks, stay active. They don't have any substantial diseases.

So IMO, the revolutionary enhancements will come from controlling diseases, so those with diseases do almost as well as those without.


It's obvious that bubbles exist in retrospect, but determining whether current growth and valuations are sustainable in the present is incredibly difficult. As another poster mentioned, we are essentially talking about market timing here.

Most investors have been conditioned by many popular talking heads to immediately dismiss the idea of successful market timing - and for the most part, the talking heads are correct. For the average investor, successful market timing is nearly impossible.

However, we have many counter-examples of successful market timers over the long term. James Simons' Medallion fund has returned 50%+ CAGR over a multi-decade period and stomping the market, creating many centimillionaires and billionaires in the process.

I set out thinking, what's so different about Simons and his crew at RenTec? Why is it so difficult for their success to be replicated? Not one to easily back down from a challenge, I began working on my own algorithms to successfully hedge against market downturns and provide superior absolute and risk-adjusted returns compared to the S&P 500. While I haven't yet seen Simons-level success in live trading, since launching Grizzly Bulls (https://grizzlybulls.com) in January 2022, 6 of our 7 models have outperformed the market on an unleveraged basis:

SPX (benchmark): +7%

VIX-TA-Macro-MP Extreme: +39.98%

VIX-TA-Macro Advanced: +34.38%

VIX-TA Advanced: +12.92%

VIX Advanced: +9.91%

Vix Basic: +5.76%

TA - Mean Reversion: +15.46%

TA - Trend: +12.97%

Of course two years of outperformance also doesn't yet stand the test of time of Simons' remarkable run, but I'm confident that we've discovered alpha here.


This is great, I am also running my own AI investment robots and this is the future and I believe you can absolutely beat the market and even thinking to use similar approach to other structured data sets and create a startup around the idea...

> since launching Grizzly Bulls (https://grizzlybulls.com) in January 2022, 6 of our 7 models have outperformed the market on an unleveraged basis:

> VIX-TA-Macro Advanced: +34.38%

I'm not sure how to reconcile that with the numbers shown on https://grizzlybulls.com/models/vix-ta-macro-advanced

When 2022 is selected as the starting year, it shows an increase from 16,911,242 to 17,881,510 which is an increase of 5.7% in 26 months.


ah, sorry for the confusion. That's because the last 20 trades are excluded from the table/chart if you don't have the appropriate access level to view, in this case a Gold membership. That means when you are looking at the chart / table with starting year 2022 you are only seeing the trades up to 3/24/2023 instead of the present.


Right, I didn't notice the end date, sorry. So that was ~5.7% return for ~15 months (not 26) and the remaining ~28.7% was in the last 11 months.


Exactly, but if you compare to the market, even though 5.7% absolute returns is a poor 15 month performance, much of the model's relative outperformance came from those 15 months where at the same point, the SPX was still highly negative


In some ways it's easier than ever before, and in others it's much harder than it was 10 or 15 years ago, depending on your industry. For software, the barriers to entry have been decimated. Modern frameworks, libraries, PAAS, and now generative AI etc massively boost dev productivity. It's viable to build an MVP as a solo dev in weeks or months that used to take years.

However, it's easier for everyone else too, and the market is now so flooded with B2B SAAS apps that it's extremely difficult to find an untargeted niche, or even one with incompetent competition, and it's even worse in the B2C space. All the low hanging fruit has been picked.

I started my own company Grizzly Bulls (https://grizzlybulls.com), an algotrading platform, two years ago and the experience has highlighted the difficulty of the non tech aspects of running the business -> marketing, sales, support, etc. It's highly niche and my indicators and models and therefor value prop are entirely unique and unclonable, but the hardest part is reaching new audience. As a freemium SAAS, we have very strong free to paid conversion and even lower premium churn so customers must be content with the product and results, but I've found it very difficult to grow the top of the funnel exposure.


Looking for niches is overrated (I say this as someone who chose to start an uptime monitor in 2021).

Tell a prospect/customer that you'll do something, actually do it, and you'll be better than 99% of the businesses out there.


No, even with all that you mention, it's still fairly difficult to make an actually good website, regardless of the amount of AI you throw at it. In contrast, the marketing side is still within how it was before, simply because devs know nothing about marketing, generally speaking.


As someone about to release a product in this space, could you give some personal insights into the marketing aspects/targeting/audience?


Frankly, I'm still very much trying to figure out viable and efficient marketing strategies myself. A large portion of my current users have come from somewhat viral posts/comments on HN, reddit and other investing forums. I also have social media accounts with automated model performance updates and free signals, but I don't have a ton of followers.

I've tried blogging and that's hit some decent results, particularly some of my technical blogs directly related to building algorithmic trading systems, but blogging is very time consuming, so I'm unsure the $/hour really pays off in such a niche space. I even wrote a book on the topic, https://www.amazon.com/dp/B0C9SB2LDG, but also that was a lot of work that I'm not sure was worth it.

So, best of luck! Marketing a very niche product/service is way harder than I originally anticipated. I'm now brainstorming how to pivot marketing towards a more mainstream audience. Really the market for investing with alpha and generating higher long term returns than the market should appeal to just about anyone with a disposable income, but building a level of trust and understanding is key.


I feel like your grizzlybulls.com site is quite nice & loads very quickly for being under the load of HN visitors. The idea of democratizing algo trading for the masses is appealing, but there is that trust factor even for mere trading signals, let alone automated trading. You may have to provide more rationale on your site for what (and which) algos can do for the everyday trader.

I think I'd give consideration to changing the name since I'm not sure the name speaks directly enough to the idea of algo trading. I'd work on finding a better one.

Your book looks interesting & I'll have to consider buying it. Good luck to you.


Thanks, really appreciate the feedback! I thought of the name Grizzly Bulls as kind of catchy since the goal is periodically hedging market downturns and so somewhat oscillating from (grizzly) bearish to bullish in macro outlook, but agree that it definitely does not feel directly connected to algotrading. I'll give it some more thought.
