If you hold a large position in one stock, you’ve probably heard the same piece of advice over the years: diversify. But when you sell to diversify, your company equity that’s vested over years, early bet that paid off, or family holding leads to a large capital gains tax bill.

Fear of the IRS shouldn’t stop you from making smart financial decisions. An exchange fund is one way to diversify your investments, without immediately triggering capital gains.

What is an exchange fund?

An exchange fund is an investment vehicle that pools stock from many investors into a single diversified portfolio. Instead of selling your shares and buying something else, you contribute them to the fund in exchange for a proportional ownership stake in the whole pool.

Because the IRS treats this as an exchange rather than a sale, no capital gains tax is due at the time you contribute. Your original cost basis carries over into the fund, and you allow 100% of your capital to continue growing.

It’s important to be accurate here. Your capital gains bill doesn’t disappear. There is no way of selling stock and avoiding capital gains. You gain ownership of a portion of the fund, and after the required holding period (typically 7 years), you can withdraw your funds. But instead of getting the original single stock you contributed, you get a diversified portfolio.

This is still not a sale, so no capital gains tax is due. You can stay in the exchange fund for longer than the 7-year holding period, or you can keep the stocks you get at withdrawal long after leaving the fund. Capital gains tax is only due when you decide to sell.

This is the trade: you give up daily liquidity in your concentrated stock for seven years, and in return you get diversification and a tax bill you control the timing of.

How an Exchange Fund Works
1. Your concentrated stock
A large single-stock position with substantial unrealized gains — selling would trigger capital gains tax.
2. The exchange fund pool
You contribute shares alongside many other investors. The IRS treats this as an exchange, not a sale — no tax due.
3. A diversified portfolio
You now own a pro-rata slice of dozens of stocks. Your cost basis carries over; tax is deferred until you sell.
No sale takes place, so no capital gains tax is due at contribution — 100% of your capital keeps compounding.

The problem: Concentrated stock and the tax drag trap

The rule of thumb when it comes to your portfolio is: no single stock should make up more than 10% of your total portfolio. For a lot of people with equity compensation, early-stage investments, or long-held family stock, that threshold was crossed years ago.

It’s a Catch-22 situation for many people. Sell, and you need to give the IRS a big chunk of your gains. Hold the concentrated stock, and your financial future can be negatively impacted by poor performance, unexpected events, and market volatility.

Say your position has quadrupled since you acquired it. Selling it outright to diversify means paying capital gains tax on that gain. Federal long-term capital gains rates alone run up to 20%, before state tax and the net investment income tax are added on top. That tax bill comes directly out of the capital you’d otherwise have working for you, and the smaller post-tax base then has to try to catch back up to where the pre-tax base would have been. That’s tax drag, and it’s the reason concentrated positions tend to stay concentrated.

An exchange fund breaks the two options apart. You don’t have to choose between “stay concentrated” and “pay the tax now.” You can diversify immediately and let the tax question wait.

How pooling and diversification work

An exchange fund accepts contributions of stock from many investors at once, in specific amounts calculated to build toward a target portfolio mix. Because every contributor is exchanging shares for a pro-rata slice of the same pool, everyone in the fund ends up diversified by virtue of participating.

You no longer hold one stock. You hold a fractional interest in dozens of them.

This only works at scale. A fund needs enough different stocks, contributed by enough different investors, to actually build something diversified rather than just holding one investor’s position under a different label. That’s part of why exchange funds have historically required substantial minimums and operated in windows rather than continuously. A fund has to gather the right mix of contributed stock before it can close and start operating.

Who can participate: Eligibility requirements

Exchange funds are private funds, and access to them is legally restricted to accredited investors. Under current SEC rules, that means individuals earning more than $200,000 a year (or $300,000 combined with a spouse), or anyone with a net worth over $1 million, excluding their primary residence.

There’s one more hurdle you need to pass: the fund has to be able to use the stock you’re bringing. If a particular stock is already heavily represented in the fund, or oversubscribed relative to demand, you may need to wait for a fund that can accommodate it, or contribute a smaller portion than you’d like.

The 7-Year holding period and the Section 721 exchange

The 7 years you need to hold your share of the fund isn’t arbitrary or fund-specific. It’s a feature of the tax code itself.

Section 721 exchanges require a genuine holding period specifically so that the IRS can treat the transaction as an actual exchange rather than a sale dressed up to avoid tax. Exit before that period is up, and you risk losing the deferral you contributed to get.

There’s also a structural requirement behind the seven years: exchange funds are required to hold at least 20% of total assets in a “qualifying” illiquid asset (usually real estate) to satisfy the tax rules that make the non-recognition treatment possible.

When the holding period ends, you’re not forced to do anything. You can withdraw your diversified basket, or simply stay in the fund and keep growing tax-deferred.

The 7-Year Holding Period
Year 0
Contribute
You exchange your stock for a stake in the fund. Tax deferral begins.
Years 1–7
Hold & compound
Your full pre-tax capital stays invested. The fund holds ≥20% qualifying illiquid assets per Section 721.
Year 7+
Your choice
Withdraw a diversified basket, or stay in the fund. Tax is only due when you eventually sell.

Is an exchange fund right for you?

An exchange fund solves a specific problem well, but it isn’t a fit for every situation.

Liquidity. This is a seven-year-minimum commitment. If there’s a real chance you’ll need this capital sooner (a house purchase, a business, an emergency) an exchange fund isn’t the right home for it.

Tax law risk. Section 721 treatment reflects current tax law. Existing participants are generally expected to be grandfathered under any future changes, but that isn’t guaranteed, and it’s a real consideration for a seven-year-plus holding period.

Market risk. Diversification reduces the risk of any one stock sinking your net worth, but it doesn’t eliminate market risk generally. A diversified basket can still lose value, and an exchange fund doesn’t promise to outperform the stock you contributed.

But if any of the following apply to you, an exchange fund can help more of your capital stay invested for longer.

  • Your investment horizon is genuinely seven years or longer.
  • You’re holding a stock position with substantial gains and want to reduce concentration risk without an immediate tax bill.
  • You meet the accredited investor threshold and can commit the required minimum.
  • You don’t have a near-term liquidity need tied to this specific capital.

How Glidepath’s model differs: No management fee

Most exchange funds charge an ongoing management fee on top of the minimum investment required to participate. Fees are typically around 1% per year. This is a cost that compounds against you for as long as your capital is locked up.

Glidepath charges no management fee to members. Over a seven-year-plus holding period, that’s the difference between a fee quietly eating into your diversified position every year and keeping the full position working for you. Glidepath can do this because our qualifying illiquid assets aren’t real estate. They’re revenue-generating assets that cover the costs for you.

Frequently Asked Questions

What is an exchange fund, and how does it work?
You contribute your concentrated stock to a private fund instead of selling it, and in exchange, you get a proportional stake in a diversified pool built from other investors’ contributed stock. Because it’s structured as an exchange rather than a sale, you don’t owe capital gains tax when you contribute. Under Section 721, that tax is deferred until you eventually sell, usually after a required seven-year holding period.
How much does it cost to invest in an exchange fund?
Most exchange funds charge you an ongoing management fee on top of the minimum investment. Glidepath doesn’t. There’s no management fee for members.
Who is eligible to invest in an exchange fund?
You need to qualify as an accredited investor by earning over $200,000 a year ($300,000 jointly), or having a net worth above $1 million excluding your primary residence.
What happens if I need my money before seven years?
You can still request an early withdrawal, but you’ll generally forfeit some or all of the tax deferral, and your provider may charge a redemption fee.
