Exchange funds: what is an exchange fund, what Eaton Vance and Cache charge, and the 20% nobody mentions.

Start with the problem it solves. You hold a position that has grown into most of your net worth, usually employer stock from a company that did well. Selling it means realizing a gain that can be taxed at up to 23.8% federal once you include the 3.8% net investment income tax, plus state. Not selling it means your financial life depends on one company's earnings calls. Both options are bad, which is why a structure that avoids choosing has existed since the 1970s. One caveat before you get this far: if any of that employer stock is still inside a 401(k), check the net unrealized appreciation treatment before the shares move anywhere, because the election is only available on the way out of the plan and it is gone once the balance is rolled to an IRA.

That last point is the one to hold on to, because the whole case for an exchange fund rests on it. Deferral is genuinely valuable: the money you did not send to the IRS keeps compounding for seven years or longer, and if the shares are eventually held until death they may receive a step-up in basis that erases the gain entirely. Deferral is not the same as elimination, though, and any pitch that blurs the two is selling rather than explaining.

Ask what an exchange fund costs and you will get a range so wide it is useless, somewhere between 0.40% and 2.00% a year. The range is wide because the category is really two different products sold to two different people, and most writing on the subject describes only the older one.

The gap that actually gates access is not the minimum investment, it is the eligibility standard, and it is the least discussed number in this category. A qualified purchaser is defined as holding $5,000,000 in investments. An accredited investor needs $1,000,000 in net worth excluding the primary residence, or $200,000 in income, $300,000 jointly. Moving from the first standard to the second expands the eligible population enormously, and that single change is what turned exchange funds from a private banking product into something you can read the price of on a website.

Two practical consequences. First, if you are researching this from a comparison article, check whether the fee range quoted describes the traditional funds or the newer ones, because a figure written for the wirehouse generation can overstate what you would actually pay by a wide margin. Second, whatever headline rate you are quoted, ask specifically whether the management costs of the mandatory 20% illiquid sleeve sit inside that number or on top of it. Those costs are real, they are rarely in the headline, and they are the part of exchange fund pricing that almost nobody asks about.

An exchange fund does not go out and buy a diversified portfolio. It receives one, from its investors, and it holds whatever they contributed. So the question of what is inside is really a question about who else showed up. The answer, historically, is people with enormous unrealized gains in technology stocks, because that is where enormous unrealized gains have come from.

Kitces reports that exchange funds have tended to resemble high-growth technology funds, running around 60% technology against roughly 33% for the S&P 500. If that describes the fund you are joining, and the concentrated position you are trying to escape is your own employer's technology stock, you have reduced single-name risk substantially while barely touching sector risk. That is a real improvement. It is not the improvement most buyers think they are getting.

The newer funds benchmarked explicitly to the S&P 500 or the Nasdaq-100 are a partial answer to this, since they manage toward an index target rather than accepting whatever arrives. Cache's stated 0.99 correlation figure is a claim about exactly this. But it is a claim worth asking about specifically, because the underlying mechanism has not changed: the fund still has to accept contributed stock, and it still has to carry the 20% sleeve. Ask for the current sector breakdown before you commit for seven years, and compare it against what you already own. Modeling the sector weights you actually want, then measuring the gap against a real portfolio, is the kind of question worth answering before the money is locked up rather than after.

Most write-ups describe the seven-year rule as a lockup and move on. The detail worth knowing is what happens if you try to leave anyway, because the terms are not neutral. A distribution taken inside the seven-year period is limited to the lesser of the current market value of what you contributed or your pro rata share of the fund.

Work through both directions. If the fund has done well and your pro rata share is now worth more than your original contribution, the cap hands you the smaller number and the fund keeps the difference. If the fund has done badly and your share is worth less than you put in, the cap is the share, and you take the loss. You hold the downside in both scenarios. That is a deliberately unattractive door, and it is unattractive by design, because the structure only works if capital stays put.

So the seven years should be treated as a genuine constraint rather than an inconvenience with an escape hatch. Before committing, the honest test is whether you could fund a house, a divorce, a medical event, a business, or a tax bill from other assets for the whole period. If the answer is no, the lockup is the deciding factor and the fee comparison is beside the point. This is also where the direct indexing route earns its keep, because it trades a slower exit from the position for the ability to change your mind at any point.

That sequence is specifically useful here because a seven-year lockup is not a decision you get to revise. Before you hand a position over, it is worth knowing what you want to be holding on the other side: how much technology exposure you are comfortable with, whether an equal-weighted construction would have behaved differently from a cap-weighted one through the drawdowns you care about, and what the fund's sector mix would do to a portfolio you already own. Those are answerable questions, they cost nothing to answer, and no provider's pricing page addresses them. If you want the wider context first, start with what direct indexing is or run the numbers on comparing your portfolio to the S&P 500.
