With the stock market at all-time highs, concentration has reached extreme levels. The top ten companies make up 40% of the S&P 500, with Nvidia and Microsoft accounting for 15% alone. Technology now represents 34% of the index, higher than at the peak of the dot-com bubble. Outside of the top ten, the other 490 companies have seen little to no earnings growth in more than two years. For investors, this raises the obvious question of what happens next. Unfortunately for us, we don’t have a better crystal ball than anyone else.
What matters now is that your portfolio is prepared for when things go sideways. One way to prepare is through proper diversification.
Diversification is often misunderstood. Traditional thinking says that if you own stocks, bonds, and real estate, you’ll have a stable, diversified portfolio. But what happens during a crisis? If all those assets fall together, are you really diversified?
The truth is that real diversification doesn’t come in the form of owning more assets, it’s about reducing exposure to the same underlying risks. Nearly all portfolios are built around a single outcome: continued economic growth supported by stable inflation and easy monetary policy. When cracks form in that narrative, as they have, everything tied to it falters at the same time.
Real diversification expands beyond traditional asset classes to include markets that respond differently to changing economic conditions. Global markets such as commodities, currencies, and metals aren’t dependent on continued economic growth to generate returns. In fact, they often perform best when traditional assets face headwinds from rising inflation, high interest rates, or geopolitical instability.
Exposure to these markets can be systematically captured through strategies that identify and follow global trends. This isn’t about predicting the future, it’s about having a process that adapts to it. Portfolios with exposure to true non-correlated strategies have historically shown lower overall volatility, smaller drawdowns, and more consistent results across market cycles. For example, diversified trend following strategies produced positive returns in four out of the last five major equity bear markets (SG Trend Index).
True diversification is about building a portfolio that can withstand many different environments. The goal is to reduce vulnerability to shifting economic narratives and create a framework that adapts when conditions change.
