Thoughts about the markets, automated trading algorithms, artificial intelligence, and lots of other stuff

  • Market Growth in the First Half of 2025.

    According to S&P Global, the U.S. market cap rose by 4.7% in the past 6th months. This represents a modest gain compared to the average market capitalization growth of 12.2% during the same period.

    Leaders in growth were South Korea, Spain, Germany, Italy, and Brazil.

    We have previously discussed this, but in addition to investments in technology and artificial intelligence, global capital is also being directed toward emerging markets, where many businesses are being established.

    At first glance, some may see U.S. underperformance, but it can also be read as a sign of relative maturity and stability. Another potential perspective is that U.S. companies have already experienced explosive growth in recent years, particularly in sectors such as tech and AI, suggesting the market may currently be in a phase of consolidation.

    While it's always great to see explosive growth, people undervalue resilience and steady growth, especially in light of the volatile first quarter of the year. 

    Time will tell! 

     

  • How Long You Have Left

    We only have a limited time on this earth … and a lot of it is spent on frivolous activities. 

    How much time do you think the average millennial spends on their phones … or a baby-boomer sits in front of the TV?

    The answer is a lot.

    Although this chart hasn't been updated recently, it still provides a helpful glimpse of the bigger picture.

    Nine years in front of entertainment devices – another 10.5 years spent working. You get the idea.

    If you have goals you want to accomplish, places you want to go, and lifestyle aspirations to experience, this puts the idea of finding and living your passion into perspective. 

    Do you have the time to waste it?

    VisualCapitalist put together a chart projecting longevity based on 2020 mortality rates.

     

    OC_Life-Expectancy-by-Age_1600px_Oct31

    via visualcapitalist
     

    According to this calculator, since I'm over 60, I only have about 20 years left.   I expect more!

    There are some interesting statistical facts in this; for example, an average American baby boy can expect to live until 74 … but if that boy turns 21, his life expectancy jumps to over 75. 

    While these numbers appear high, there are two key considerations. First, COVID-19 heavily reduced these numbers because mortality rates increased. 

    Also, remember that these numbers are based on 2020 averages, which may differ from your own (specifically considering your race, income, location, etc.). These numbers also don't take into account expected medical and technology advances, etc. 

    Ultimately, I believe Purpose is one of the most significant catalysts of longevity. People often die when they retire … not because they're done working, but because they're done striving. 

    If you're not growing, you're dying!

  • What My Recent Surgery Reminded Me About Technology.

    One of my recurring messages is to focus on what you want, rather than what you don’t want.

    Likewise, I believe the best way to get through challenging periods is to focus on your resources or progress.

    Anyway, two weeks ago, I had a minor surgery.

    Let’s face it, very few people “want” to have surgery (even small ones) … and, for those that do, it’s a sign that something else is bothering them even more.

    As much as it sucked, I have a lot to be grateful for. The practical realities of time, technology, and progress made the procedure and the recovery process easier than at any point in our species’ history.

    Procedures that used to mean multiple days in a hospital bed have you home in under 24 hours.  

    It brought back memories of my knee surgery from 12 years ago… and reminded me of what technology makes possible.

    Before my knee surgery, I wasn’t enjoying the prospect of the needles, the knock-out drugs, the cutting, or the recovery process. Frankly, I was scared.

     

    130113 What - Me Worry
     

    History is littered with tales of once-rare resources that have become plentiful through innovation. The reason is pretty straightforward: scarcity is often context-dependent.

    Imagine a giant orange tree packed with fruit. If you pluck all the oranges from the lower branches, you are effectively out of accessible fruit. From that limited perspective, oranges are now scarce. But once someone invents a piece of technology called a ladder, the problem is solved.

    Here is a picture from inside my knee (unlike years ago, they didn’t have to slice me open to gain access for the picture or the repair): less damage, less time, less drugs, less recovery.

     

    130113 Knee Surgery

     

    Bottom-Line: I walked over 2,500 steps the day after the surgery. 

    Think how far diagnostics and surgery have come since then?

    Whether it is 3D imaging, minimally invasive surgical instruments, or linking big data and elastic computing, technology is a resource-liberating mechanism. It can make the ‘once scarce’ the ‘now abundant’ (or ‘readily accessible’) … and a lot less painful.

     

    From ‘Doctor Klingon’ to Clarity — and What That Means for You

    But where are we today – and how was surgery different?

    It sounds like a joke, but the future of medicine is in your pocket.

    One of the biggest differences for me was having AI available to help me feel informed throughout the process. From the beginning, where I wanted to understand the issue and potential solutions, to having AI available on my phone in the recovery room. For example, while waiting for the doctor to tell me “how things went,” I downloaded the surgical notes from the hospital portal, only to find that they were written in “doctor speak” Klingon. So I opened Perplexity in incognito mode and asked it to interpret the notes, and explain everything to me as if I had minimal medical knowledge but still wanted to understand what happened and what I should expect. The result was incredibly comforting, and I was able to use that to send updates to family and friends.

    Meanwhile, try to imagine the extensive technology used by doctors and medical staff throughout the process to test, analyze, interpret, monitor, and treat.

    Soon, we’ll be able to utilize real-time data for diagnostics and design treatment plans and preventive care tailored to an individual’s unique biology and lifestyle. As a result, personalized, predictive healthcare will become the norm. Likewise, the idea of tailoring treatment to your unique biology will be expected, not exceptional.

    It’s also easier than ever to imagine the shift from reactive to preventive medicine. Surgery will become less frequent as AI and wearables catch problems before they require intervention. Likewise,. That means better care and better outcomes – at scale!

    And it is all getting better faster than before.

    Pretty cool! 

  • Diminishing Returns in AI: The Most Common AI Mistake

    At some point, more of the same stops paying off … it is called the law of diminishing returns.

    Law of Diminishing Returnsvia Sketchplanations

    Nature (and common sense) reminds us that equilibrium is important. For example, when you exercise too much, you get injured; when you drink too much water, you get poisoned; etc. 

    This concept applies almost everywhere.

    • It's why diversification is so important in portfolio construction theory. 
    • Or, why you don't want to put all your eggs in one basket (concentrating your risk).
    • And, my favorite, it's also why you shouldn't only eat vegetables.

    A related nugget of wisdom from the extreme … Too much of a good thing is a bad thing! 

    And of course … Be moderate in everything, including moderation.

    A recent study on the effects of ChatGPT use on brain activity also supports this theme. 

    via "Your Brain on ChatGPT: Accumulation of Cognitive Debt when Using an AI Assistant for Essay Writing Task" 

    The study divided 54 subjects into three groups, and asked them to write several SAT essays using ChatGPT, Google, or nothing at all. They used an EEG to record the writers' brain activity. ChatGPT users showed the lowest brain engagement. Over time, ChatGPT users got lazier. 
    As a result, the ChatGPT essays also ended up lacking original thought and sounding similar. 
     
    The paper suggests that the use of LLMs could harm learning and retention. The group that wrote without any help showed the highest neural connectivity, and higher brain activation in creativity ideation, memory load, and semantic processing. This group was more engaged and curious, and expressed higher satisfaction with their work. 
     
    The paper hasn't been peer-reviewed yet and has a small sample size. 
    Ultimately, I think it's telling us something we probably could have already guessed. If you're not actually the one reading or writing something … you're not going to absorb the information as well. Your brain isn't going to activate as well. And if you're not finding other places to train your brain, you'll get worse at critical thinking. 
     
    A few weeks ago, I wrote about my research process and how AI has both bolstered and hindered certain aspects of it. I'm casting a wider net, but going less deep. 
    So now, I’m exploring how to maintain a balance. I still want to leverage AI’s value, while reintroducing a layer of slowness and reflection into the process. Maybe that means manually summarizing some articles. Maybe it means pausing to journal about what I’ve read, or discussing it with someone. The goal is not to abandon the efficiency — but to ensure that efficiency doesn’t come at the cost of depth. - via "Is AI Making Your And Your Team Smarter?"
    This isn't a call to avoid AI or to slow down its development. It's a call to deliberation and intentionality. Students are flaunting that they're using ChatGPT to shirk the system. Companies are releasing AI-written copy not only on their websites but also in press releases. Humans are falling in love with chatbots and leaving their spouses. 
     
    Meanwhile, AI is also the underpinning of countless enhancements and increased productivity. 
     
    The same thing happened with the Internet. 
     
    At a certain point, overreliance becomes a crutch, not a tool. 
     
    I bet AI makes unintelligent and lazy people lazier and less intelligent. 
    I'm positive it can make YOU smarter and more effective if you use it in moderation and to support your unique abilities. 
    Onwards!

  • My Artificial Intelligence Journey

    Time seems to go faster as I get older. Likewise, technology seems to be advancing faster than ever, too.

    Take AI as an example… even though I've been involved in this field for many years, I'm surprised by how rapidly it's improving now.

    I suspect that part of the surprise comes from comparing the current pace of change to my memories of how long it took to improve in the past. Even though I had a sense of the quickening, the thing about exponential technologies is that there's a tipping point … and clearly we're past that point on the curve.

    I'm often met with surprise when I talk about my AI journey … because it began in 1991, when it was still hard to spell AI.

    Looking back, it makes a lot more sense to me than it did as I was moving through it. Here is a video about that journey and what it means for you and your future. 

     

    Click here to view the transcript of the video.

    Looking back on my life and career, one could argue that I got my start in AI with my most recent company, Capitalogix, which was founded over 20 years ago. Or, perhaps, we could go back further and say it started with my previous company, IntellAgent Control (which was an early AI company, focused on the creation and use of intelligent agents). By today's standards, the technology we used back then was too simple to be considered AI, but at the time, we were on the cutting edge.

    Maybe we should go further back and say it started when I became the first lawyer in my firm to use a computer … or was it when I first fell in love with technology? 

    The truth is … I've spent my whole life on this path. My fascination with making better decisions, taking smarter actions, and getting better results probably started when I was two years old (because of the incident discussed in the video).

    Ultimately, the starting point is irrelevant. Looking back, it seems inevitable. The decisions I made, the people I met, and my experiences … they all led me here.

    However, at any point in the journey, if you asked, "Is this where you thought you'd end up?" I doubt that I'd have said yes. 

    I've always been fascinated by what makes people successful and how to become more efficient and effective. In a sense, that's what AI does. It's a capability amplifier. 

    When I transitioned from being a corporate securities lawyer to an entrepreneur, Artificial Intelligence happened to be the best vehicle I found to do that. It made sense then, and it makes sense now.

    Like most things in life, it's easy to see the golden thread looking backwards, but it's a lot harder to see projecting forwards.

    I wouldn't have it any other way. It certainly keeps things interesting.

    Onwards!

  • My Best Investment …

    My kids are getting older. In fact, not only are they both adults, but they're both married. Father's Day looks a little different than it used to. 

     

    Fathersdayfb

     

    As I look back, I realize that there was an investment I made that paid off in a big way, and I want to share it with you.

    Like many parents, I wanted to teach my children that, to a large extent, they control what happens to them. One of the first ways I did that was to set up a "compensation system" for them to earn video games.

    Some parents try to limit the amount of time their kids spend watching TV or playing video games. I tried something different. Instead, my kids earned their games by reading books. Here is a photo from way back then.

    BZandH_edited

    Paid With Play.

    Here's how it worked. When they were younger, 10 books were enough to earn a small game. When they finished a book, it was their right, and my obligation, to take them to the bookstore for us to pick up the next book together. Likewise, when they finished the requisite number of books, it was their right, and my obligation, to take them to the computer store or game store for them to choose any game they wanted.

    When they finished a hundred books, they got a bonus of earning the next game system. That meant if they had a Nintendo, they could now also get a PlayStation 3 or Xbox 360.

    How Can You Encourage a Jump to the Next Level?

    There came a point when I wanted one of my sons to start reading grown-up books. He was comfortable reading a certain type of book, and didn't want to read the kind of books that I read. So, I created a bonus system that counted a particular book as three books. I didn't force him; I just let the easier path to a reward "whisper" in his ear what to read. Once he finished that, he never went back to teen fiction.

    It Is a Great Way to Learn About Your Kids.

    I also used the bookstore visits to gauge how the boys were doing. For example, I might say, "I notice that you read five books in that series, maybe you'd like this book". Or, "That sure is a lot of science fiction; what was the last biography you read?"  For the most part, though, I didn't care what they read. The key was to get them to want to choose certain books for their own reasons. Ultimately, their preference meant they were learning to love reading.

    It Puts Them In Control of Their Destiny and Rewards.

    My younger son likes competition. He also broke or misplaced many things. So, to earn back the Game Boy unit he lost, I challenged him to read five books in five days. These weren't easy books either. It was designed to stretch him, and also to teach him that he could read a book a night. The bet was that he either finished all the books in the allocated time, or none of them counted towards games or Game Boys. On the other hand, if he read a book a night for two weeks, not only would he get his Game Boy back, but the books would also count towards a game. It worked like a charm, and we were both happy.

    So, Who Got the Better Bargain?

    As they started to get into their teenage years, I needed to up the ante a little. So, 500 books meant they got a laptop of their choice. Both boys cashed in, and probably felt like they were taking advantage of their dad.

    I got what I wanted, though; both my boys love reading, and know that they can accomplish anything they put their minds to … one step at a time.

    Here is a recent picture of us.   All of us love reading … and none of us needs diapers.

     

    39C25ED2-732A-4E0D-B301-1A698E0E50E7

    Speaking of diapers, I've leveled up to become a grandfather. Watching my oldest become a father is the ultimate dividend.

    I still remember my father joking with me to be careful of what I said about him, because I would have kids who would do the same to me.

    Watching my granddaughter grow, explore, and enjoy the world is an incredible blessing. 

    Plus, I know Karma is a Bitch. … wait till she starts using everything she's learned against him.

    It is part of the cycle of life … just like diapers.

  • Major Asset Class Performance Since 2020

    Last week, we highlighted the growth of cryptocurrencies. This week, we're taking a look at the performance of various asset classes during the previous 5 years – including Bitcoin. 

    To start, let's get a sense of where things stand year-to-date.

    This has been a "strange" year. As someone who follows Markets, I'm still surprised by how many times I'm tempted to say that.

    In addition, I'm also surprised by how well global assets have fared year-to-date.

    Here's a high-level overview.

    Gmi.tab_.01may2025 (Asset Class Returns)
    via CapitalSpectator.

    After a seemingly significant string of losses, U.S. stocks experienced a surprising rebound in May, marking their first monthly gain since January. This upturn propelled U.S. equities to the top of the performance leaderboard among major asset classes during the month. The rally was driven by broad strength across global markets, though some segments, particularly bonds in developed markets, faced declines.

    Equities and bonds typically have an inverse relationship. Recently, both markets have been reacting sharply — stocks up, bonds down. This dynamic reflects uncertainty. The market is balancing hope and fear simultaneously — hope in economic recovery and corporate earnings, and fear of tighter monetary policy.

    Game theory suggests that the conflicting incentives between growth-focused and risk-averse investors create a dynamic equilibrium sustaining this paradox. However, this brings up an uncomfortable question for investors:

     
    What if the erosion of bonds’ safe haven triggers a systemic liquidity crisis when protection is most needed?

     

    That is where a longer-term lens is particularly helpful, both for providing context and offering insights into portfolio mix and diversification strategies.

    The infographic illustrates how major asset classes performed each year over five years, highlighting the impact of external shocks and policy changes. It emphasizes the importance of diversification by showing how different assets respond uniquely to economic shifts, enabling investors to identify risks and opportunities in recent market cycles.

     

    via Visual Capitalist.

    Bitcoin has performed better than I expected during the past five years, attracting both institutional and retail investors. Meanwhile, gold has seen renewed interest as falling interest rates and easing political uncertainty have led some investors to seek safer assets, reflecting a shift toward lower risk tolerance in segments of the market.

    It's interesting to see the dichotomy between these two asset classes and their growth, despite their almost inverse profiles. 

    Meanwhile, 2025 has been a rocky year for many asset classes. If you like potentially meaningful (but likely meaningless) factoids, 2025 has seen the S&P 500's fifth-worst start to a year in history. 

    It will be interesting to see how the rest of this year plays out.
