Buffett Roasts Your Finance-Heavy Portfolio: Stop Copying Berkshire!

I was pouring myself a Cherry Coke and putting on my reading glasses to review this portfolio, but for a second, I thought someone had accidentally handed me Berkshire Hathaway's latest 13F filing! Looking at this is a bit like looking in the mirror—and at 93, let me tell you, that's not always a pleasant experience, but in this case, I'm flattered.

It seems you’ve been doing a lot of reading about Omaha, and you’ve built yourself a beautiful little homage to value investing. My old partner, Charlie Munger—bless his soul—would probably look at this, give a little grunt of approval, and say, "Well, at least you aren't doing anything completely stupid." You've bought wonderful businesses at what I hope were fair prices. But investing isn't just about riding on my coattails; you need to have the stomach to hold these businesses when Mr. Market goes into a manic depression. Let's look under the hood and see if you actually know what you own, or if you're just looking over my shoulder during the exam.

First off, let’s talk about that 14.3% cash reserve. I like that. Cash earns a terrible return over time, but it’s the oxygen you need when the market hyperventilates. Having dry powder means you don't have to sell good businesses to pay for life's surprises, and you're ready when a fat pitch comes right down the middle of the plate.

Looking at your sector breakdown, you are heavily concentrated in Finance, sitting at nearly 43% of your capital. You’ve also heavily favored North America, which makes up roughly 76% of your geographic exposure. I've always said never bet against America, and you certainly aren't.

I see you value a competitive moat just as much as I do. Between intangible assets like patents and brands (about 31%) and scale advantages (nearly 28%), you are well-protected from the castle invaders. Apple at 15.3% is a marvelous consumer business, not just a tech company. And seeing Coca-Cola at 8.4% warms my heart. You've even got Costco in there at 5.1%—Charlie would be smiling down at you for that one. You also ventured overseas exactly where I did, grabbing Mitsubishi at 4.3%. Those Japanese trading houses are practically printing cash.

Even a portfolio filled with wonderful businesses can have a few blind spots. Here is where you might be making a mistake:

🚩 The "Copycat" Risk: The biggest danger here isn't the stocks you picked, it's how you picked them. You have nearly 22% of your money in Berkshire itself, and the rest is almost a direct copy of our holdings. If you are just mimicking my trades, you will always be a step behind when I sell. You need your own conviction, or you'll panic the minute the market drops.

🚩 Heavy Bank Exposure: Between American Express (7.2%), Bank of America (6.1%), Mastercard, JPMorgan, and Nu Holdings, you are swimming in the financial sector. Banks are highly leveraged businesses tied to the hip of the macroeconomic cycle. If the credit cycle turns nasty, half your portfolio is going to catch a severe cold.

🚩 Geopolitical Blind Spots: I noticed Taiwan Semiconductor sitting there with a 3.8% allocation. It is a phenomenal enterprise—one of the best managed in the world. But I bought it and sold it relatively quickly because I didn't like the neighborhood it lives in. Geopolitics matter when the business is physically concentrated in a tension zone. Ensure you have the stomach for that risk.

I'll give this portfolio an 8.5 / 10.

I can't grade it much lower without insulting my own life's work, now can I? It's a robust, moat-heavy, sensible collection of cash-generating enterprises. But to get a perfect score, you need to show you can think for yourself.

Here is what I recommend you do next:

1. Maintain that cash discipline: Keep that 14.3% reserve right where it is, perhaps in short-term Treasuries, until Mr. Market offers you a screaming bargain.

2. Read the Annual Reports: Don't just own Bank of America and Chevron because I do. Read Brian Moynihan's and Mike Wirth's letters to shareholders. Understand the plumbing of the businesses you own.

3. Assess your financial concentration: Take a hard look at your bank holdings and ask yourself if you are comfortable holding them through a deep, prolonged recession. If not, trim them when times are good.

I'll leave you with a simple truth Charlie and I always lived by: "A wonderful company at a fair price beats a fair company at a wonderful price." You've got the wonderful companies down. Now just let time and compound interest do the heavy lifting.
