I remember reading this headline and then going and looking at the XMAG index[0].

YTD: +15.5%

1 year: +9%

Since inception (Oct 2024): +14%

Comparing that with S&P500

YTD: +16.7%

1 year: +13%

Since XMAG inception: +18%

The article should start with such a comparison but it just seems like a lot of text with very little numerical comparison, which makes it not very useful to conclude what the case is.

    Correct! Backtest and compare ratios to common indexes!

    If we made a similar comparison to the SP500 index since its inception in 1926, and made a chart of total returns difference over 1 year sliding window, between index and index minus it's top 7 performing stocks, i bet we will see this recent period isn't at all exceptional. Every economic boom is propelled by one or two sectors that have a limited number of players.

So if we look at companies that didn't do as well, we find that they didn't do as well as those that did really well?

    I guess the story here is more like

    If you take the Top 500 companies as an indicator how well your economy is doing, but everything is carried on the shoulders of only 1.4% of those 500 companies then what is the point of looking at the 500 companies in the first place.

    Make an S&P10 then instead. or in addition to the S&P500

    That would probably be a good way to look at it anyway. Looking at the trend of the S&P10 vs. S&P500 and if they agree then thumbs up, but if they disagree then things might not be as rosy as everyone thinks

      The problem with that approach is you miss out on the gains of tracking a company from when its market cap is small to when it is large, and only capture the opposite as it leaves the top 10.

      This is one reason people are so concerned with companies going public later. If they just appear in their fully formed embodiments then you can only capture their growth after they are large and their death.

    No, it's about relative value. Obviously it's a tautology to announce that you've discovered that stocks that did really well outperformed ones that didn't.

    The interesting thing is that the aggregate market gains are almost entirely concentrated in those stocks. It's not a statement about sorting, it's a statement about distribution.

So a viable strategy would be to only buy the best 7 stocks? Like the Dogs of the Dow, but reversed? (The Gods of the Dow?)

    It works until it doesn't. And it can stop working very fast. Which is the scary part. But then it also depends on entry point. If you entered early even going down say 40% or 60% might not make you go red.

    Yeah, investing in the top companies leads to higher returns for most periods when looking short term.

    Over longer periods, the top companies by market cap tend to change though. https://www.investmentnews.com/equities/only-one-of-the-worl...

    So if you want to invest in the top companies, you either need to think they won’t change anymore, or you need to find when to buy and sell. Index funds solve this problem for you, albeit with slightly lower returns in the short term.

    It's only a "strategy" because you know what happened to the share price. If you can tell the future why not buy the lottery instead.

The stock market has been dominated by a single industry many times in history: railroads (Union Pacific), oil (Standard Oil, later Exxon), steel (U.S. Steel), banking (JPM), industrials (GE), telecom (ATT), computer hardware (IBM, MSFT, Intel), smartphones (Apple), consumer internet (Facebook, Google, Amazon) and now "AI" (Nvidia, Magnificent 7).

Isn't the interesting question now: what follows? Or does history end with Mag7?

  • epolanski 2 hours ago

    I think that the overall point is that gargantuan big tech capex is hiding an overall weakness in the economy.

Different than when the railroads dominated the market, or the industrials dominance in the 20s and 30s, or the nifty fifty, or the communication dominance in the late 90s?

Does the S&P 493 reveal a different economy or does it reveal that the author published an article based on feelings instead of research?

  • Mistletoe 5 hours ago

    All those ended pretty badly, right?

    • spwa4 an hour ago

      Problem is, eventually everything ends badly. You can make this argument about "average S&P500 company", and the time in which it ends badly has gone down over time. In the last 10 years the average S&P500 company ends badly after about 18 years.

      If memory serves it was about 30 years in 2000, and much longer before that.

      By contrast most of these mania lasted a lot longer.

In previous years, I could have excused such shoddy journalism. In the age of LLMs that can do the work for you, it’s inexcusable that the author didn’t pick 3-5 sample strong economies from the past to judge today by.

  • faidit 3 hours ago

    Such as? (edit: to clarify, since you apparently downvoted me for asking [lmao], what exactly are these 3-5 alleged success stories for monopolism/crony capitalism that ChatGPT told you about?)

    • sokoloff 2 hours ago

      A user cannot downvote a comment that’s directly in reply to their own.

      It was likely other user(s) who downvoted a comment that they perceived as low-effort and adding little to the discussion, which I could easily see if the entire comment was something like “Such as?”

      • faidit an hour ago

        I see, thanks. FWIW I was succinct because I didn't think a comment to the effect of "I prefer to let AI do my thinking for me" merited a substantive response. I was (and still am) also genuinely curious what these 3-5 examples were. South Korean chaebols? Roman latifundia? Perhaps we'll never know

Why the fuck is TSLA ever included in this list?

  • readthenotes1 3 hours ago

    Because of how well its stock has done since 2020 compared to the s&p 493.

propaganda. "the economy isn't actually good!"

they won't even show a chart in the article. 493 is up ... look at a 2025 5y chart. not that "basically flat" (actually 2023) chart google tries to feed you as a top result.

  • mschuster91 an hour ago

    > propaganda. "the economy isn't actually good!"

    The thing is, there are three distinct interpretations of the word "economy", and depending on which of the definitions you subscribe (or belong) to, either of "the economy is good/okay/bad" can be true!

    1) being the economy for the (uber) rich, "big tech", "big seven", FAANG, however you want to call it. That economy is running hot on 'roids "thanks" to the AI ouroboros / bubble / incestuous investment relationships. Money printer go brr. You get it. The only thing you have to take care about now if you belong to that bubble is to slowly unwind enough bags onto clueless retail gamblers before the bubble pops.

    2) being the economy for the pension funds, the value of all the "dumb capital", S&P 500/DAX/MSCI and the likes. That economy is doing ... okay-ish, partially thanks to the AI bubble, but when that bubble pops, it's going to have Covid/2007ff effects on the pension funds.

    3) being the economy for the 99% - and that economy is in the gutter. On the income side, job losses run rampant across the board, especially "entry level" jobs but also skilled jobs like translators are getting wiped out by AI, and in other industries (advertising, "luxury" goods) the cause is people cutting back on spending because they don't have any money left or are holding their money together because they fear a serious macro-economic disaster. On the expense side, cost of living have been exploding for years without adequate salary hikes - rents, basic groceries, cable TV and its replacement of half a dozen of streaming services, gas, electricity, the impact of Trump's tariffs, whatever.

    Not recognizing (or ignoring) these wildly different realities is what killed Trump 1, Biden and is now killing Trump 2. You can't go and yap on the big screen about the economy being at record highs while the actual reality on the ground is everything but that. And it's not just the US that has these problems either, it's the same across the board in Western countries. The only thing the US has "exclusively" is the tariffs.
