Buffett’s Roast: Why Your Global Index Strategy Is Being Undermined

Well, hello there. Looking at this portfolio reminds me a bit of a fellow who builds his house on a beautiful, solid granite foundation, but then decides to construct a makeshift casino up in the attic. You’ve only been tracking these accounts for a couple of months, so as far as performance goes, the jury is still out. We don’t judge a marathon runner by their first two steps out of the starting blocks, and being down a fraction of a percent right now means absolutely nothing in the grand scheme of a thirty-year horizon.

I have to chuckle at your two different accounts here. In your main retirement account, you've got a sensible, long-term outlook. But then you've got a separate sleeve literally called "Trading experiments" with a five-year horizon. Charlie Munger and I always believed that if you want to gamble, you should go to Las Vegas—at least the drinks are free. Wall Street is a very expensive place to seek thrills. But let’s pull up a chair, crack open a Cherry Coke, and see what you actually own.

The smartest thing you’ve done here is anchor over half of your entire net worth in a global index fund. Keeping 51% of your wealth in that iShares global ETF for your pension is a wonderful decision. By owning a slice of world businesses, you are letting the long-term tailwinds of human ingenuity do the heavy lifting for you. Broad market index funds make up over 60% of your total pie, and that alone gives you a margin of safety against your own worst instincts.

However, your cash reserves are sitting at a rather thin 4%. With central banks holding rates where they are right now, and capital flying around chasing artificial intelligence acquisitions and geopolitical headlines, a little dry powder is a wonderful thing. Cash is a terrible long-term investment, but it’s the only thing that lets you reach for a bucket instead of a thimble when it suddenly starts raining gold. You don't have much flexibility if Mr. Market decides to have one of his depressive episodes tomorrow.

I also took a look at your geographic and sector breakdown. You’ve got a heavy tilt toward North America and Emerging Markets beneath that global umbrella, alongside some specific Eastern European plays. Some of these domestic choices show promise—Dino Polska, for example, is a classic domestic compounder with real scale advantages. Finding a business that grows steadily by dominating local markets is right out of the Berkshire playbook. On the technology front, you've picked up companies with real switching costs, like Microsoft, which is a fantastic fortress of a business.

🚩 "Because it's a Polish ETF" is not an investment thesis. You bought the Beta MWIG40TR fund and literally wrote that your goal is to hold it "when something better will appear." Using a fund as a temporary parking lot for your money is a surefire way to get a parking ticket. If you don't have a wonderful business to buy at a fair price, just hold cash.

🚩 Buying a business with no moat. You have nearly 7% of your retirement account in TAURON Polska Energia. It's a state-linked utility heavily burdened by coal and regulatory headaches. This is a classic value trap. A fair company at a wonderful price will almost always cause you grief. Turnarounds seldom turn, and structurally disadvantaged businesses rarely create long-term wealth.

🚩 Overpaying for growth without a safety net. You’ve sprinkled a lot of capital into software names like Klaviyo, monday.com, and Zscaler. These might be fine products, but growth at any price is a dangerous game. Some of these are down near 30%. And your PayPal position, down over 52%, is a harsh lesson in what happens when a pioneer's competitive moat is breached by a hundred new competitors.

🚩 The "Trading Experiments" mindset. Naming an account "Trading experiments" tells me you're thinking like a speculator, not an owner. Shuffling around CD Projekt and a China ESG fund hoping for a quick 10% annual bump isn't investing. If you wouldn't be comfortable owning the whole business for ten years, you shouldn't own a fraction of it for ten minutes.

I'm going to give this portfolio a 6.5 out of 10. The heavy, disciplined allocation to a global index fund is the heavy lifter here and saves your grade. The rest of the portfolio, however, is suffering from "deworsification"—adding inferior businesses that drag down your wonderful ones.

Here is what I would suggest you do:

1. Build up your cash: Get those cash reserves closer to 10%. Stop treating mediocre ETFs as a waiting room for your money. Cash gives you the option value to strike when a truly fat pitch comes across the plate.

2. Ditch the coal utility: Sell TAURON. Life is too short to invest in heavily regulated, state-linked companies with no competitive advantage.

3. Shut down the casino: Fold your "Trading experiments" into your main account. Treat every stock purchase as if you are buying a local farm or an apartment building—you buy it for the cash it produces over decades, not because you hope the quote goes up next Tuesday.

4. Demand a Margin of Safety: If you are going to buy individual tech companies, make sure you aren't paying a price that requires perfection for the next ten years just to break even.

I spend my days reading hundreds of pages of annual reports at a desk with no stock ticker on it, because the daily price simply doesn't matter if you own the right businesses. Focus on the businesses, ignore the noise, and let the magic of compounding do its work.
