Finally got to write about a meta trend that I've noticed for a while! Quant firms are ramping up academic sponsorships, building AI labs and generally talking about themselves more -- as they face growing competition for talent from AI labs bloomberg.com/news/articles/…

WHAT MAKES A GOOD LEADER? I’ve been reading and loving the recent biography about @TomBrady, particularly how he managed to inspire and push a team to become a dynasty. It’s made me reflect on leadership in general. Yesterday, @MikeBellafiore called a firm-wide meeting due to underperformance. His message wasn’t negative. Nobody was scolded or yelled at. Instead, he acknowledged the problem, had senior leaders propose solutions and share their perspectives, and expressed his belief in the team’s ability to improve. It was a great example of leadership. Many of the world’s most successful leaders are highly competitive, intense, and demanding. Sometimes to the point of being massive assholes. Think Steve Jobs, Elon Musk, or Michael Jordan. When I led a trading floor, I was intensely competitive and, at times, a huge asshole. Looking back, I think much of that behavior was counterproductive. But I also recognize where it came from: caring deeply, having extremely high standards, and constantly pushing myself and others toward their limits. As I’ve grown and matured, so have my views on leadership. I increasingly believe the most important traits are: 1. Leading by example. You’re willing to get in the trenches alongside your team, as Brady consistently did. You hold yourself to at least the same standards you expect from others. 2. Bringing out the best in people. You challenge people to grow beyond what they thought possible, even when that process is uncomfortable. 3. Putting the greater good first. You make decisions based on what’s best for the team or organization, even when those decisions conflict with your own interests or those of individuals you care about. 4. Taking ultimate ownership. You accept responsibility for outcomes, communicate expectations clearly, and ensure people understand the consequences of their actions. 5. Establishing the culture and standards. You create an environment that rewards excellence, accountability, continuous improvement, and collective success. As silly as it might sound, I actually think Ted Lasso is an amazing role model for leadership. His ability to connect with people, understand what motivates them, and bring out their potential is something I deeply admire. However, even today, I still believe there are times when a leader needs to be willing to be perceived as the asshole. Sometimes a message needs to be delivered forcefully. Sometimes people need to understand the gravity of their underperformance and the consequences of failing to improve. Sometimes you have to make difficult, unpopular decisions that upset people in the short term but ultimately serve their development or the greater good. And different individuals respond to different approaches. Some thrive under intense pressure and direct criticism. Others perform best when challenged through encouragement, trust, and positive reinforcement. A great leader understands those differences and adapts accordingly without compromising their standards. What I’ve come to appreciate is how difficult it is to strike the right balance. Push too softly, and you risk complacency and mediocrity. Push too aggressively, and you risk undermining the very people you’re trying to develop. The truly great leaders, whether nicely or meanly, set a standard and intensity so far greater than the individual would hold themselves to and they hold the group to it even at the expense of the feelings of the individual.

Nice poker analogy. There are some really bad flops when you have AA - easy to talk yourself into confidence b/c you have Aces.
Later today we are having a firm-wide trader meeting at @smbcapital. A few teams and a couple handful of traders have been struggling. This aligns with what I’m hearing from other desks as well as those on the retail side. Only fair for me to highlight both the successes AND the struggles of the traders I work with as I try to convey the authentic truth of being a trader. On the SMB call we will discuss what has been working well, what hasn’t been, and how best to adapt. Soliciting feedback across teams and individuals. Here is the main message I will be conveying to their traders which I think is useful for all to hear: IMO, the most common issues I’m seeing is that traders are getting overly involved and over-allocating risk to situations that had potential but never unfolded optimally. $BWET is a name that got extended, but never enough to take a real stand. The breakouts in $QQQ or certain single-stock names had solid charts but the breadth beneath the market was awful. We still had yellow lights flashing in certain areas. The recent AI sell-off was extended and had its moments, but it lacked the intraday flush or intraday setups to size into anything. When these setups have unfolded suboptimally, traders have continued to stay involved and allocate risk in a refusal to acknowledge that the setup is not as good as it had the potential to be. I’d argue this comes down to maintaining an objectively high level of subjectivity. Selectivity is staying in your lane and waiting for the setups in your playbook that match the current regime. Unlike w poker, nothing is forcing you to play or to take a subpar setup. Essentially, you have a good hand and want to place a bet, but if the flop pans out suboptimally, you fold. A lot of traders have not been emotionally willing to fold and not play the hand. Good trading is recognizing that there might be some positive signs, but then avoiding or sizing down when it doesn't fully line up.

It's crazy that there's a tool out there that's become vital to they way I do my job, parent my kids, and make major life decisions; and yet we barely spend more on it than AI
TIL that global spending on alcohol is still larger than AI infrastructure spending this year ($1.7T vs $1.5T)

It's never as good or as bad as it seems in the moment.
My first funded account had an incredible first month. It ruined my mindset. It took me months and a blown account to understand why.

This describes very well the real problem with even systematic traders (who have "figured it out" in some sense) sizing up too quickly.
You win 5 trades in a row and start to feel like you've figured it out. So you double your size on trade 6. That's usually the one that takes back the whole week.

That seems like a good approximation of what's possible. Incredible time to be a systematic trader!
"This is essentially four years' worth of work built by a team of at least 10 people if we're using the pre-AI measurement, or, alternatively, one person can do this in under a month now."

For trend following this is true , but I don't think so for mean reversion.

Several years ago, @MikeBellafiore coached me through a large loss, similar to what he describes here. The drawdowns are what you'll remember, even if they eventually become small blips on your equity curve. Great video Mike!
Want to know the ultimate test of a trader? Hint: It isn’t how much you make when the market is easy. It’s what you do after a devastating loss that completely defines your career. [02:39] This month, one of our top trading desks at SMB Capital took a tough loss. They were long a position when an unexpected, intervening event dropped out of nowhere and hammered the stock. The damage? Down over $3 million. [00:13] In prop trading, that plunges a desk straight into what we call "the hole" [00:13]. Before these guys see another dollar of payout, they have to grind back every single dollar of those millions just to get back to flat [00:23]. Bad beats happen. Losses happen. It flat-out sucks, you feel it right in the pit of your stomach, and the pain lingers [02:32]. It is what you do after the loss that matters—not the loss. [09:10] The $3M deficit matters very little in the long run compared to how the team and its individual contributors respond right now [02:49]. In our latest video, I broke down the exact 6-step blueprint this elite desk is using to climb out of their hole [03:26]: 1. Run a Forensic AAR (After Action Report): Stripping emotion from P&L [03:42]. The team leader didn't bury the loss in a large pepperoni pizza and a bottle of red wine [04:47]. He delivered a candid, constructive autopsy: owning his mistakes, analyzing hedge execution, and praising the quick-thinking put purchases that saved another $2M in damage [04:20]. 2. Collaborate Across the Desk: As Ray Dalio observed, viewing the market through one pair of eyes means missing critical information [05:04]. On our desk, an impressive junior 7-figure producer respectfully pushed back on the star's self-critique, arguing the entry add was technically sound and purely hit by an exogenous intervening shock [05:32]. That open debate is where real edge compounds [06:01]. 3. Bring the Trade to the Firm Crucible: The desk brought the trade to partners, risk managers, and mentors like @theonelanceb [06:13]. Risk reviewed limits, senior partners coordinated tech solutions for faster news execution, and coaches challenged the floor [06:23]. A painful rip becomes rocket fuel when your entire firm has your back [06:50]. 4. Chip Away with One Good Trade: As Market Wizard Marty Schwartz famously said, greatness isn't hitting home runs; it's stringing together singles and doubles [07:02]. No desperate YOLO swings. The team leader set the tone: "I am just going to chip away at these losses." One Good Trade. And then One Good Trade. And then One Good Trade [07:25]. 5. Grounded Veteran Optimism: As Colin Powell noted, "Perpetual optimism is a force multiplier." [07:49] The senior leader reminded the desk that drawdowns are temporary, he's clawed out of every hole before, and each slump made him a better trader [08:09]. Veteran leadership eliminates panic [08:26]. 6. Game Plan High-Conviction Catalysts: Don't predict—anticipate [08:37]. The team mapped out high-opportunity environments ahead (like the Anthropic IPO and potential Q4 momentum) to deploy asymmetric risk when the setup aligns [08:48]. The market will knock you down, but your career isn't defined by the brutal blow—it is defined by the grit, discipline, and character you display when you stand back up. It is what you do after the loss that matters. #DayTrading #PropTrading #SMBCapital #TradingPsychology #OneGoodTrade How to Recover from a big loss (as quickly as possible) youtu.be/djDZP9lvVqc?si=qCeR… via @YouTube

Good message from Lance. Get after it! Time is wasting...
It is hard to make progress if you aren't honest with yourself. Don't sit there telling yourself that you are an A-player and giving 100% if you're not. Don't sit there telling yourself that the market is the issue and you're doing everything you can. Don't sit there saying your goal is to be a pro trader, but you spend more time scrolling social media than doing the difficult work to become a pro. Now look - it is totally fine to make X dollars when your potential is 10X. It is totally fine to be a hobbyist or a part-time trader because you enjoy the challenge. But just don't bullshit yourself because reality is undefeated.

I’ve become more active lately bc of an automated orb strat (thank you @davemabe) and leveraging the use of a funded equity prop firm (@TradeThePool). After reviewing my stats, I’ve given back something like 3x not taking profits…I have the opposite problem of most, I hold onto trades for too long.
