We have been lied to for decades. Financial advisors and “experts” have consistently hammered home the idea that the only responsible way to invest is to diversify. They tell you to spread your money across every corner of the globe and every asset class imaginable.
But here is the cold, hard truth: if your objective is maximizing investment profits, traditional diversification is effectively a strategy for mediocrity. By trying to avoid every possible risk, you are guaranteeing yourself inferior returns.
The High Cost of the 60/40 “Safety” Net
The stock/bond balance is perhaps the most expensive advice ever given to the middle class. The 60/40 portfolio is designed to reduce volatility, but it does so by dragging an anchor behind your wealth.
Over long periods, stocks have fundamentally crushed bonds. When you allocate 40% of your portfolio to debt, you aren’t just “balancing” your risk; you are opting out of the compounding power of the world’s greatest companies. For a long-term investor, the “reduced volatility” of bonds is a luxury you pay for with a significantly smaller retirement nest egg.
Why International Diversification is Dead Weight
Since World War II, the United States has been the primary growth engine of the global economy. Comparing the U.S. to Europe or Asia is often a losing game for investors.
The U.S. Innovation Monopoly
- Innovation Dominance: The U.S. is the home of the giants—Google, Facebook (Meta), Nvidia, Apple, and Tesla.
- Regulatory Freedom: While Europe is busy creating new regulations that stifle growth, the U.S. remains the most fertile ground for capitalization and scale.
- Risk Appetite: The American economy is built on taking big swings, whereas many other industrialized nations have become too risk-averse to produce the next wave of disruptive tech.
If you have diversified globally over the last few decades, you haven’t gained security. You have simply diluted your exposure to the best-performing market in history.
Rebalancing: Selling Winners to Buy Losers
The idea that you should diversify within industries to catch “rotations” is equally flawed. We are told that when one sector is up, another is down, and we should rebalance to stay even. This is a recipe for selling your best performers to fund failing industries.
Consider the shift in the American economy. A century ago, agriculture represented 25% of the U.S. economy; today, it is roughly 1%. Conversely, Technology has grown from nothing to the dominant force of the 21st century. If you would have taken money out of techology sector bucket to put it into the agricultural sector bucket, you would be so much worse off.
VOO vs. RSP: The Proof is in the Weighting
Look at the difference between VOO (Market Cap Weighted) and RSP (Equal Weighted):
- VOO allows the winners to grow and take up more space in your portfolio.
- RSP forces you to sell your top-tier performers to buy more of the laggards at the bottom.
- The result? VOO drastically outperforms because it follows the momentum of success rather than the “fairness” of diversification.
Conclusion
If you want to play it safe and be average, follow the herd into “global diversification.” But if you are serious about maximizing investment profits, you must recognize that concentration in winners is how real wealth is built. Stop buying the “dead weight” of the world and start betting on the engines of growth.
FAQ
Doesn’t diversification protect me during a market crash? It might reduce the “dip” on your screen, but it also reduces the recovery. Over 20 or 30 years, the growth you lose by being “safe” is almost always greater than the losses you would have sustained in a temporary crash.
Why shouldn’t I invest in emerging markets? While emerging markets offer high potential, they lack the institutional stability, legal protections, and innovation ecosystem that allow U.S. companies to dominate globally.
Is it ever okay to own bonds? Bonds are for capital preservation, not growth. If you are already wealthy and want to stop making money and just keep what you have, bonds make sense. If you are still building wealth, they are a hurdle.
