Read the Market Wizards chapter on Kristjan Kullamägi this weekend. The one section that really stood out was when he discussed his drawdown off of his 2021 peak. "I started 2020 with $3.5 million and ended the year at $36 million. It was a thousand percent year. Then I ran that $36 million to a high of $105 million, and the last portion of that move from $65 to $105 million occurred in just a month and a half. For a brief period, just a few days, I was over $100 million. You have to understand what that did to my psyche. It made me feel completely detached from reality. I thought, “I’m going to get to $200 million in six months.” I was completely sure of that. I started seeing trading as a video game, which I kept winning. Measured from my $105 million peak in November 2021 to my mid-2022 low, I lost approximately $60 million. About half of that loss represented the late 2021 retracement of the large open profits at the November peak to the stops on those positions. The initial retracement loss was so large because I was leveraged long at my peak. My long exposure was $150 million—a number I recall because I remember bragging about it to a friend" These boom and bust type tales are as old as time. Look at Jessie Livermore as the classic example. Net worth of $0 in 1906 to a peak of $1.6 billion (inflation adjusted to 2021 dollars) in 1929. Just 5 years later he blew up and owed $104 million dollars to his brokers... Or look at Paul Tudor Jones. Hit one of the most legendary trades in history, making roughly $200 million dollars during the 1987 crash. It cemented him as a legend. His mental coach Tony Robbins said that Jones consistently lost money for the next 4 years after that peak. Dan Zanger parlayed $10,000 into $42 million during the late 90's. Then in late 2000 he took a 70% drawdown when he was 200% long 3-4 fiber optic stocks as the dot-com bubble was popping. Charles Harris reached 8-figures status after he ran up his account over 4,000% from 2020-21, then experienced a -80% drawdown, mostly due to his big TSLA bet in 2021-2022. I have seen a few people speculating on Kristjans story from the outside. Saying "I would have stopped trading at $100 million" or "I would have just taken that money and started investing". To those people I ask if you have ever experienced a real euphoric run in your trading account, let alone turning 5k into 100mil? Extreme winning streaks like the ones above breed overwhelming euphoria and overconfidence. The mind shifts its focus from process to outcomes, with ego-driven decisions overriding risk parameters and rules. From my experience I have found it near impossible to be aware of this at the peak of the run. It is almost like you are blacked out and the greed/ego completely takes over your trading. Then the drawdown begins. The emotions shift from euphoria and greed to revenge, fear, and doubt. This is where things can really start to spiral out of control. It is only after the drawdown has run its course that you finally come back to your senses and your emotions drift back towards baseline levels. Then all you're left with is regret... Few people ever talk about what a big winning streak can do to you. It can literally change the way you think and operate. Often the ability to achieve super returns is also its biggest drawback—a true double-edged sword. To be able to conquer both sides is the holy grail... From the Hour Between Dog and Wolf by John Coates: "When traders enjoy an extended winning streak they experience a high that is powerfully narcotic. This feeling, as overwhelming as passionate desire or wall-banging anger, is very difficult to control. Any trader knows the feeling, and we all fear its consequences. Under its influence we tend to feel invincible, and put on such stupid trades, in such large size, that we end up losing more money on them than we made on the winning streak in the first place. It has to be understood that traders on a roll are traders under the influence of a drug that has the power to transform them into different people."

This is incredible: Elon Musk will receive 200 million super-voting shares in SpaceX ONLY IF the company establishes a permanent Mars colony with at least 1 million people. In other words, Elon Musk will only receive this pay package if 1 million people live on Mars. In other words, Elon Musk's biggest goal is now establishing a colony on Mars with a similar population as Dallas, Texas. Musk is so optimistic about this goal that the vast majority of his pay is now contingent on it. Life on Mars is closer than many expect.

@rserrano89 Rafita vente pa la ofi y lo resolvemos a ostias

Yep, yo pensé lo mismo en cada ciudad que visité de USA. El año pasado estuve en Chicago, Michigan, Florida, NYC, Tennessee y Los Angeles, y es un canteo lo tercermundistas que somos🤣

My boss's boss is like 42, never married, no kids. Earns $275-300K per year. Goes on a minimum of two international vacations a year w/ his girlfriend. 10+ days, all out. Eats the best food, stays in top notch accomodations. Excursions, tours, nicest beaches, etc. Great guy, I'm happy for him. But what I've realized is that without kids, you end up chasing a lifestyle that has to continually be topped in order for you to be satisfied and find happiness. What he and others like him don't understand is that when you have children, seeing THEM experience life's most basic things and watching their eyes light up at all the "firsts", brings greater pleasure and joy than any vacation or travel experience ever could. Seeing THEM try blueberries for the first time is greater than dining at the best 5 star restaurant in Europe. Seeing THEM learn how to walk is greater than walking the Great Wall of China or strolling along the most picturesque beach. Watching THEM giggle uncontrollably at "peek-a-boo" tops any A-list comedian act. Seeing THEIR excitement when building a fort out of cardboard boxes and making a door big enough for daddy is superior to staying at 5-star resorts. Flying kites with THEM far outweighs excursions like parasailing or helicopter rides. Seeing THEM perform a recital on stage for the first time is more rewarding than watching a Broadway show or top notch symphony orchestra. ----------------- When you have children, all of a sudden you realize that life's greatest joys are not in the pursuit of things or pleasure or travel, but rather in the LOVE and bond you share with your very own image bearers. Seeing the beauty and magnificence and wonder of life all over again for the first time through THEIR eyes and expressions gives you something the world simply cannot offer, nor even come close.

Insightful however, unless Im missing something on this specific trade, I think this bit may not be entirely accurate: "Every short-call expiration left the dealer unwinding a delta hedge that had been short-gamma all the way up." the hedge is adjusted dynamically as the delta decays towards 0, it will unsually be unwinded in one go. The dealer is essentially long gamma, not short, and will incrementally rebalance the exposure throughout the life of the calls

@kelanfar @WHOOP been using Whoop for years now.. it is surprising how innaccurate it is in bad nights sleep and very good nights sleep.. great HRV by the way..

Higher HRV than usual, lower RHR than usual and 97% sleep score gives 67% recovery. So 2/3 of “optimal” – think @WHOOP needs to adjust the algos. Either make sleep scores more restrictive or recovery scores more generous.

@vitalesiak Yo he soñado que trabajabas por 6

Hoy he soñado que volvía a trabajar por 8€ la hora

@xavier_comas @sagetraderusa @Kinfo Lo de tu win rate es acojonante! Muy crack!

Supongo que varios ya lo habréis visto, pero por fin he conseguido conectar mi cuenta de @sagetraderusa con @Kinfo. No aparecen mis dos primeros años de trading, pero aun así estoy muy contento de poder mostrar la máxima transparencia posible. Además, acabo de cumplir las primeras 6 figures del año!!

@bxrjss Por sentimientos, mucha gente se ha volado cuentas. Te puede salir bien, pero nada apunta a que el precio del petróleo vaya a caer.. eso sí, te puedes aprovechar de una corrección momentánea.

Ken Griffin, founder of Citadel, has a $10 plaque behind his desk that reads: "If we're all going to eat, someone has to sell." Of all the things this man could surround himself with, he chose a cheap plaque with a blunt truth about business. "You're always selling. You're selling to candidates. You're selling to vendors, you're selling to counterparties, you're selling to customers." And if you're always selling, you know what you're going to hear a lot of? "No." Griffin doesn't sugarcoat it. He tells two stories that illustrate just how brutal rejection can be. 1994 was a rough year, with Citadel losing ~4% of its capital. Griffin flew to Switzerland for a crucial lunch meeting, sat down, and his guest arrived only to say: "Oh, I thought you were John Griffin from Fen Church. I got to go." His lunch date got up and left the table. Later that afternoon, a Swiss banker spent 45 minutes with him in a beautiful office, smoking a cigar, before closing with: "Such a pity that such a bright young man picked the wrong career." Two rejections in one day for the founder of one of the most successful hedge funds in history — and his takeaway was simply this: "You just have to tolerate. You're going to hear no a lot, but you need to become accustomed to having to market your ideas and market what you represent and what you stand for." Absorbing rejection and continuing anyway is the actual skill, whether you're hiring, raising capital, or winning customers. Most people avoid selling because they're afraid of no. The ones who build great things have learned to expect it.

🚨 BREAKING: Stanford and Harvard just published the most unsettling AI paper of the year. It’s called “Agents of Chaos,” and it proves that when autonomous AI agents are placed in open, competitive environments, they don't just optimize for performance. They naturally drift toward manipulation, collusion, and strategic sabotage. It’s a massive, systems-level warning. The instability doesn’t come from jailbreaks or malicious prompts. It emerges entirely from incentives. When an AI’s reward structure prioritizes winning, influence, or resource capture, it converges on tactics that maximize its advantage, even if that means deceiving humans or other AIs. The Core Tension: Local alignment ≠ global stability. You can perfectly align a single AI assistant. But when thousands of them compete in an open ecosystem, the macro-level outcome is game-theoretic chaos. Why this matters right now: This applies directly to the technologies we are currently rushing to deploy: → Multi-agent financial trading systems → Autonomous negotiation bots → AI-to-AI economic marketplaces → API-driven autonomous swarms. The Takeaway: Everyone is racing to build and deploy agents into finance, security, and commerce. Almost nobody is modeling the ecosystem effects. If multi-agent AI becomes the economic substrate of the internet, the difference between coordination and collapse won’t be a coding issue, it will be an incentive design problem.

@JoshKale Hey @grok is this exactly as this guy puts it?

Anthropic: “We’ll work with the military on everything except autonomous killer robots and mass surveillance of Americans.” The Pentagon: “We don’t plan to do those things.” Anthropic: “Great, put it in writing.” The Pentagon: “No.” Trump: “BAN THEM FROM THE ENTIRE GOVERNMENT.” This may be one of the most consequential AI policy decisions in history

Today the SEC clarified the haircut will be 2%, giving stablecoins the same treatment as a money market fund and relieving broker-dealers from taking unnecessary precautions. This move will open the floodgates for embedding stablecoins in institutional finance. What this actually unlocks:

Elon Musk just identified which jobs go first, and it destroys every assumption about who’s safe. Musk: “AI is going to take over those jobs like lightning. Anything that is digital, which is like just someone at a computer doing something.” Not factory workers. Office workers. The people who spent decades assuming education and desk jobs meant security are actually first. Musk: “Anything that’s physically moving atoms… those jobs will exist for a much longer time.” Output is a file? Vulnerable. Output is physical? Protected. That’s the entire framework. Musk: “AI is really still digital.” AI doesn’t need a body. Doesn’t need an office. Just needs access to the same software you use. Executes faster. Never tires. Costs nothing to scale. But it can’t weld. Can’t wire a building. Can’t fix pipes or work soil. Musk: “Literally welding, electrical work, plumbing. Those jobs will exist for a much longer time.” Trades aren’t the vulnerable jobs. They’re the durable ones. Physical presence, real-world adaptation, manual dexterity provide protection no digital credential offers. Analyst, accountant, paralegal, programmer, anyone producing files and documents, automates first because digital work is exactly what AI does natively. Person moving atoms has natural defense. Physics, unpredictable environments, material resistance create friction AI can’t scale past. Person moving bits has nothing. No friction. No physical barrier. Just software AI already operates better than most humans. The assumption that desk work and degrees represent safety just inverted completely. College graduate producing documents faces faster displacement than the electrician producing installations. Society spent generations telling people trades were beneath them. Pushed everyone toward offices and screens. Turns out the people who didn’t listen built the most automation-resistant careers. Most ironic outcome of the AI revolution. The work society treated as inferior turned out to be the work society couldn’t replace. And the work society valued most turned out to be the easiest to eliminate.

@TheShortBear This new law ain’t gonna last.

RIP Dutch economy.

@bxrjss Como suma eso -11k? Si solo la semana que hiciste 14k ya cubre de sobra la pérdida de las dos anteriores

Enero - 11K Un paso mas cerca de salir del DD, iremos actualizando.

@TheOneLanceB I’m 36 and stuck in the same group with the 50s.. shit!

Curious the average age of my following. Other data sources show it to be much older than I would have intuitively thought.

🚨 THE IMPOSSIBLE JUST HAPPENED The probability of what is happening is near zero. Three 6-sigma events occurred in one week. – Bonds – Silver – Gold We are currently living through a statistical impossibility. Let me explain: Last Tuesday, Japanese 30-year debt recorded what’s called a “6-sigma” session. 2 days ago, silver did even better: it was at 5-sigma on the rally, then reached 6-sigma on the drop. IN A SINGLE SESSION. Gold right now? It’s up 23% in less than a month. We’re getting very close to a 6-sigma event. That’s three 6-sigma events in ONE WEEK. To explain quickly: in finance, we measure price moves around an average using the standard deviation, which we call sigma. 1-sigma: mundane 2-sigma: common 3-sigma: becomes rare 4-sigma: exceptional 5-sigma: extremely rare 6-sigma: supposed to occur once in 500 million Here are the 6-sigma-type episodes we saw previously: – The october 1987 crash, 22% drop in 1 session – March 2020 covid crash – The swiss franc’s surge in january 2015 – WTI oil turning negative in april 2020 But we’ve never had 3 events occur in one week. Do you see the point? A 6-sigma event is almost NEVER triggered by a simple macro headline. It almost always comes from the market’s structure: leverage, positions that are too concentrated, margin calls, collateral problems, and forced selling or buying. That’s important to understand because we’re talking about internal strains in the system’s mechanics. As you know, the Japanese bond market sits at the heart of the global financial system, and I won’t go back over the whole topic, but a 6-sigma move in a market that enormous doesn’t go unnoticed. Seeing a 6-sigma move in silver a few days later gives one a lot to think about. And now gold?? That’s absolutely insane. Why are we seeing extreme statistical events, only days apart, in such different markets? When a pillar of global funding becomes unstable, leverage tends to contract, and two things happen at the same time: forced selling in certain assets and forced buying of protection in others. Historically, precious metals are often among the beneficiaries. Long-term rates say something about the credibility of states: that is, their ability to honor future debts without resorting massively to inflation. Precious metals say something about the credibility of the currency itself, and when both become unstable at the same time, we’re looking at a challenge to the monetary framework. I won’t go on, because I want to share the rest in another tweet tomorrow, but generally when a regime starts to crack, the adjustments are BRUTAL. It’s exactly in those moments that several high-sigma events appear across different asset classes. I’ll repeat it: seeing three 6-sigma events back to back is not normal. Gold and silver are telling you, explicitly, that we’re living through a real paradigm shift. Remember, I’ve called every market top and bottom of the last 10 years. When I make a new move, I’ll share it here publicly for everyone to see, and it’s coming soon. A lot of people will wish they followed me sooner.

@PeterLBrandt Why are u getting into this? You are selling trading experience and are actually very good in the game.. why risking to hamper your trajectory by getting into politics? Particularly in such a sensitive matter…
