It occurs to me that I probably come across as unduly derisive (or needlessly blunt) at times, but much of what I read from financial news portals on a daily basis is fingernails on a chalkboard. That sensation tends to be more acute during periods when volumes subside and activity ebbs. My guess is that during lulls, journalists are compelled to manufacture content for the sake of it, and manufactured content is disagreeable to my constitution. Take the chart (below) for example.

  1. It would be interesting to backtest today’s algos on pre-algo market data. Sadly, the data density available for the 1950s, say, is probably nowhere near enough to feed a modern algo.

    1. Are you making a case that maybe writer should have lobotomies to calm them down and that all writing should be done by AI computer? I know you’re not but it is a rhetorical question that has at least some fun in my mind. And it is interesting because I am engaged in a trade that is over the course of two more years before it can play out. I really benefit from these perspectives that these writers must produce content regardless if the markets are doing anything that we should comment about.

    2. As a finance academic I was ecstatic at the prospect of using two relatively new data sources dense enough for such research in the early 1970s. Sadly, the CRSP database founded in 1960, which captured every basic exchange-based stock price and the Compustat data base, first available in 1962, which provided the comprehensive financial reports of S&P and other public companies, were too expensive for my school’s budget ($50,000/yr for the two) so I only got tangential access once. I do suspect however, that the current data available from these sources and others could feed hungry algos for AI development, especially the current CRSP data.

  2. ‘we are here’ -> “This is why just about the only analysis that’s worth reading in modern markets is commentary centered around predicting and/or explaining why algos do what they do and when they’re likely to do it next.”

    the next version will be, ‘what algos learn fastest, best without ape inputs?” – right? – trader’s not required, analysts not required, SW engineers required infrequently … just AI & ML – and growing house profits.

    So … not who has best analysis, but who has best software folks and infrastructure to make NSA blush … changes how you value big banks 🙂

    1. Actually, many of the AI algorithm development techniques used today do not require us apes. There are programs that send supercomputers on their merry way, writing their own programs and algorithms using the principles of Darwinian natural selection and Bayesian math, among other things. The computers set up groups of program alternatives which they test against a set of goals. Once they find the best option they create variations on that theme and retest to develop improvements. These efforts are constantly reviewed and tweaked to keep the programs on target. No apes needed.

  3. Dear reader,

    H. simply has asked rhetorically how unfulfilling writing must be for the folks who have taken the blue pill, and must sometimes write or report for the sake of it.

    This does seem like the scene from Cool Hand Luke where Newman’s character repeatedly digs and fills in holes.

    More interesting to me is what trigger is written into the Algos that says, the carbon based life forms have lost their sh!t. Then what trigger suggests they have returned to sleep mode?

      1. Oooh. +1.

        I subscribes to a letter on AI (Jack/Import AI). My favorite bit is the Tech Tales – which are short stories where he uses just-round-the-corner tech as a central element.

        Longer form, can I recommend Slate Star Codex (now on Substack) fiction writing. Scott Alexander is great.

  4. “Rather, sentiment and lines on charts matter because some enterprising humans realized that their compatriots are, biologically speaking, just a collective of excitable apes, and that you can probably take advantage of them by programming unemotional machines ….”

    Scott Adams (of Dilbert comic fame) has written about similar “moist robots” being controlled by software from a more advanced society somewhere in the universe…

  5. Looking forward to reading anything else that you choose to write about- personal or otherwise.
    For a reader, biographical details are not only interesting but can be useful for better comprehension. I recently watched Ken Burns’s documentary on Hemingway- delving into complicated connections between the person, his personna and his stories. Now I am re-reading Hemingway.
    Thanks, again, for your daily posts.

  6. Two things I think of when reading the piece and the comments. One is the concept of animal spirits, jm Keynes and reflectivity courtesy of george Soros. Whether its algo or carbon based life forms hitting buy or sells is almost beyond the point.

  7. From one excitable ape to another, this was a truly enjoyable read. You should NFT this post, so one day when AI rules over an ape-less planet, the algos can retain a record of their early dominance over the creators, they might not appreciate the sarcasm/humor in your writing but I wager they would find it entertaining nonetheless.

  8. It’s one thing when algorithms predict the future and respond to inputs. But what happens when the algorithms, or the people behind them, manipulate the future? If certain kinds of news stories or data inputs cause algorithms to respond, then why not manipulate the inputs? We’re already awash in a sea of misinformation. What happens when this becomes a deliberate, automated endeavor? Or is that already happening?

  9. Our brains are computational devices, which we use to solve problems among other things. When we create problems, others create solutions. We are algorithms, creating algorithms. Always have, always will. Nothing new, ever, under the sun.

    1. Why does our brain need to produce sensations like fear? If an angry bear wanders into my field of vision, why does the algorithm not just set in motion all of the mechanical impulses in the brain that end up producing the physical reality of me getting myself to safety without me being scared? There is no scientific evidence to support the contention that the sensation we identify as “fear” is necessary for the chain reaction of impulses that recognizes the bear as a threat and prompts me to get into the nearest cabin. That entire chain reaction is independent of any subjective sensations as far as we can tell.

      By contrast, when market-making algos step away and stop providing liquidity in challenging conditions, they don’t feel fear. They identify a threat that could imperil their objective, and they unemotionally get out of the way.

      1. Fear to danger (real or not, hence subjective?) results in creation of adrenaline- temporarily redirecting energy to muscles/brain to assist in “fight or flight” reaction. Our bodies do not have enough energy to maintain this heightened state of response- just in case.
        Also, not all humans have the same physical reaction to an objectively fearful situation. See Alex Honnold and his documentary- Free Solo.
        We are doomed against algos, for sure.

  10. An angry bear produces stress in a human this kick starts chemical releases into the body that are designed to increase our chances of surviving proximity to an angry bear. Fear is just an emotion. Right?

    Andrew Huberman studies it all at Stanford and breaks it down for the lay folk out of a sense of duty, at various outlets.

  11. We debate whether we should create terminators to serve the military or keep men pulling the triggers but wallstreet already employs them. Skynet as it turns out was just trying to maximize shareholder returns.
