Key takeaways
- The AI boom — and more specifically, the surge in hyperscaler data centers — seems to have become the primary driver of global financial markets, creating some potential diversification challenges.
- But we see nuances and further differentiation within the AI trade, as some investments appear better positioned than others across areas such as equities, private markets, alternative credit and real assets.
- More broadly, we are finding value in municipal bonds and real estate, which are continuing to enjoy growing tailwinds.

The concentration paradox: Why fewer drivers demand a broader perspective
Saira Malik, Chief Investment Officer
To focus is to ignore.
Raise your hand if you instinctively lower the volume on your car stereo when trying to spot street signs or landmarks as you drive through unfamiliar surroundings.
You’re not alone. Noise and other sensory intrusions make it harder to concentrate, and brain science confirms that quieting down to see better can be, well, a sound strategy. Today’s investment environment is noisy, too. Geopolitical gyrations, volatile short-term economic data and the incessant thrum of prediction markets all contribute to the cacophony, to the point that many investors would rather forego navigating the complex soundscape and instead feel compelled to favor a one note song — the artificial intelligence (AI) trade.
The result is concentration of a different sort: U.S. equity market leadership, earnings growth and benchmark index composition are increasingly concentrated in a small number of AI-related names. Just 28 companies in the S&P 500 Index (less than 6% of the total), including the Magnificent Seven, accounted for roughly 50% of the index's market capitalization at the start of the year, according to JPMorgan. In Q1 earnings season, which wrapped last month, year-over year growth for the information technology sector came in at +54% — nearly double the S&P 500’s overall rate — while the Mag7’s +63% growth dwarfed results for the remaining 493 companies, according to FactSet. Beyond equities, AI is also a powerful force in fixed income and real assets markets, further complicating the case for diversification.
Going with the AI flow may be the path of least resistance but unlike tuning out distractions while driving concentrating on a single theme might not get you to your destination. The narrower the focus, the greater the likelihood that other compelling ideas will be overlooked. Limiting potential sources of diversified risk and return in this way isn’t a sound strategy.
That’s not to say AI no longer presents attractive investment opportunities. But the trade has become more nuanced as investors shift their gaze from which companies are spending the most on AI to which ones are actually generating a meaningful return on their investment. This distinction, along with specific tailwinds and headwinds in various AI-related subsectors and industries, is a topic we explore in our “Five portfolio construction themes.”
We also discuss the broader mix of asset classes we favor beyond the well-trodden AI trail. These include alternative credit and private markets (equity, debt and real estate), where selectivity and deal structure are paramount, and which offer a degree of insulation from AI disruption and geopolitical noise. We also make the case for municipal bonds (both investment grade and high yield), a category that continues to benefit from steep yield curves and strong fundamentals.
Our updated heat map and senior investment leaders’ best ideas in their respective asset classes provide further details and travel tips for broadening the scope of your portfolio horizons. May the road rise to meet you, and may you lose your concentration along the way — but only in the best sense of the word, of course.

Important information on risk
All investments carry a certain degree of risk and there is no assurance that an investment will provide positive performance over any period of time. Equity investing involves risk. Investments are also subject to political, currency and regulatory risks. These risks may be magnified in emerging markets. Diversification is a technique to help reduce risk. There is no guarantee that diversification will protect against a loss of income. Debt or fixed income securities are subject to market risk, credit risk, interest rate risk, call risk, tax risk, political and economic risk, and income risk. As interest rates rise, bond prices fall. Investing in municipal bonds involves risks such as interest rate risk, credit risk and market risk, including the possible loss of principal. The value of the portfolio will fluctuate based on the value of the underlying securities. There are special risks associated with investments in high yield bonds, hedging activities and the potential use of leverage. Portfolios that include lower rated municipal bonds, commonly referred to as “high yield” or “junk” bonds, which are considered to be speculative, the credit and investment risk is heightened for the portfolio. Credit ratings are subject to change. AAA, AA, A, and BBB are investment grade ratings; BB, B, CCC/CC/C and D are below-investment grade ratings. As an asset class, real assets are less developed, more illiquid, and less transparent compared to traditional asset classes. Investments will be subject to risks generally associated with the ownership of real estate-related assets and foreign investing, including changes in economic conditions, currency values, environmental risks, the cost of and ability to obtain insurance, and risks related to leasing of properties. Investors should be aware that alternative investments including private equity and private debt are speculative, subject to substantial risks including the risks associated with limited liquidity, the use of leverage, short sales and concentrated investments and may involve complex tax structures and investment strategies. Alternative investments may be illiquid, there may be no liquid secondary market or ready purchasers for such securities, they may not be required to provide periodic pricing or valuation information to investors, there may be delays in distributing tax information to investors, they are not subject to the same regulatory requirements as other types of pooled investment vehicles, and they may be subject to high fees and expenses, which will reduce profits. Alternative investments are not appropriate for all investors and should not constitute an entire investment program. Investors may lose all or substantially all of the capital invested. The historical returns achieved by alternative asset vehicles is not a prediction of future performance or a guarantee of future results, and there can be no assurance that comparable returns will be achieved by any strategy. Responsible investing incorporates Environmental Social Governance (ESG) factors that may affect exposure to issuers, sectors, industries, limiting the type and number of investment opportunities available, which could result in excluding investments that perform well.
