Review direct holdings and the underlying holdings of your funds, then consider whether your investments are spread across companies, industries, and asset classes in a way that suits your goals, time horizon, and tolerance for risk.
How to check whether your portfolio is concentrated
Look through your portfolio at two levels: the securities you own directly and the holdings inside each mutual fund or exchange-traded fund (ETF). A fund can own many securities while still concentrating your money in a small group of companies or a single industry. Overlap matters too: several funds may hold many of the same companies.

Group exposures by company, industry, and broad asset category. Consider which holdings are connected to AI-related businesses, but do not treat an AI label as a precise measure of risk: the SEC sources cited here do not provide an AI exposure calculator or establish how much AI exposure a typical investor has. Fund objectives and current holdings are more useful starting points than names alone.

Ways to broaden your investments
Spread exposure within stocks
Check whether your stock investments cover a range of companies, industries, and geographic areas, rather than relying heavily on a few technology businesses. Broadening the number of holdings can reduce dependence on any one company or segment, but the number of holdings alone does not prove that the portfolio has the balance you want. Examine what those holdings actually are and how they overlap.

Consider more than one asset class
Diversification can also mean holding different types of assets, not just different stocks. Stocks have growth potential but can be volatile. Bonds are generally less volatile and have more modest returns, although some types carry higher risks. Cash equivalents generally have lower investment risk but can lose purchasing power to inflation. The right mix depends on your circumstances; these tradeoffs do not point to one allocation that is right for everyone.
Inspect funds instead of relying on the label
An ETF, mutual fund, or index fund is not automatically diversified. Investor.gov, the U.S. Securities and Exchange Commission (SEC), cautions: “But a mutual fund or ETF won’t necessarily provide diversification, especially if it is narrowly focused (such as on one industry sector).” Some ETFs may track a single stock, and a sector-focused fund can reinforce an exposure you already have.
Before investing, review the fund’s objective, top holdings, breadth, costs, and risks. For index funds, consider fees, trading costs, and tracking error—the difference between a fund’s performance and that of the index it seeks to follow. Recheck current disclosures because fund holdings and expenses can change.
How to decide whether to rebalance
Market gains and losses can move your portfolio away from its intended allocation. Rebalancing means adjusting holdings to bring the mix closer to that target. It may involve trimming an investment that has grown to take up more of the portfolio than intended.
Rank #3
The SEC describes two general approaches: review and rebalance at regular intervals, or act when an allocation drifts past a preset percentage. Neither approach is a universal schedule or threshold. Choose a method that fits your plan and circumstances, and consider account-specific tax questions before making changes.
Compare choices against your goals
There is no universally best fund or allocation for reducing AI-related concentration. When comparing possible changes, ask:
Rank #4
- How broadly does the investment spread exposure across companies, industries, and geographic areas?
- Does it duplicate holdings or risks already present in my portfolio?
- What asset class is it, and what volatility, return potential, or inflation risk comes with it?
- What are its expenses, trading costs, and other relevant risks?
- Does it fit my time horizon, goals, and tolerance for losses?
If individual tax, account, or goal questions materially affect your decisions, consider consulting a qualified financial planner. This is general educational information, not individualized financial advice.
What diversification can—and cannot—do
Spreading investments can reduce reliance on a single company or segment, but it cannot eliminate investment risk. As Investor.gov puts it, “Diversification can’t guarantee that your investments won’t suffer if the market drops.”
The practical aim is to understand where your exposure sits and make deliberate choices about its breadth and balance—not to assume that a particular AI forecast, fund label, or fixed allocation guarantees protection.
