Earned or Returned? The One Test That Tells You Where Your Yield Comes From

A 12% yield and a 19% yield can look like the same kind of win on a brokerage screen. They are not — and the difference often isn’t the headline rate at all, but where the cash comes from.

Every distribution is funded by one of three things: the income a fund actually earns, gains it realizes, or a quiet handing-back of your own principal. That last one has a friendly name — return of capital — and learning to tell the constructive kind from the destructive kind is the single most useful skill an income investor can build.

The fruit and the firewood

Picture your fund as an orchard. Net investment income — the dividends its stocks pay and the interest its bonds throw off — is the fruit. Harvest the fruit every season and the trees keep producing. That is a distribution funded by earnings, and it can run indefinitely.

Return of capital is different. Sometimes the manager hands you fruit that simply hasn’t been picked yet — value that has grown on the tree but wasn’t sold, passed to you as cash. The orchard is intact; you just got an advance. That is constructive ROC.

But sometimes the fund runs out of fruit and starts cutting down trees to give you firewood. The check still arrives. It might even be larger. But every log was a tree that will never bear fruit again. That is destructive ROC — and a fund that does it consistently is shrinking the very thing that generates your future income.

The trouble is that on your statement, the picked fruit and the chopped tree look identical. Both show up as “return of capital.”

Why ROC is a tax label, not a verdict

Here is the part the marketing rarely explains: return of capital is a tax classification, not a measure of performance. It tells you how the IRS treats the cash, not whether the fund earned it.

ROC isn’t taxed in the year you receive it. Instead it reduces your cost basis — the price the IRS considers you paid — which defers the tax bill until you sell. On your 1099-DIV it appears as a nondividend distribution, set apart from ordinary income and qualified dividends.

For a tax-managed fund, that deferral is a genuine feature. For a fund quietly liquidating itself, the same tax label is camouflage. The classification alone can’t tell the two apart. So you need a test that ignores the label and looks at the economics.

The NAV acid test

The cleanest test of whether a distribution was earned requires one number most investors never check: the fund’s net asset value, tracked over time alongside what it paid out.

The logic is simple arithmetic. Add the distributions a fund paid to the change in its NAV over a period:

• If NAV plus distributions holds steady or rises, the fund earned its payout. The cash came from real economic return, whatever the tax form says.
• If NAV plus distributions falls, the fund paid out more than it made. The shortfall came from your principal — destructive ROC, regardless of how attractive the tax treatment looked.

A fund can carry a 96% return-of-capital label and still pass this test with room to spare. Another can pay you “income” and quietly fail it. The 1099 won’t flag the difference. The NAV will.

Apply it: two funds, two verdicts

To see the test work, hold a constructive payer next to a destructive one.

SPYI — the NEOS S&P 500 High Income ETF — is constructive ROC done deliberately. It runs a covered-call strategy on the S&P 500 and pays a distribution rate of roughly 11.9%, monthly, of which about 96% is classified as return of capital. On its face that sounds alarming. The acid test says otherwise: since the fund’s 2022 inception its NAV has risen about 7.5% (from $49.13 to $52.82), even as it paid out those ROC-heavy distributions the entire time.

That ROC is a tax strategy, not erosion. SPYI uses Section 1256 index options, which receive 60/40 long-term/short-term treatment, plus opportunistic tax-loss harvesting, to characterize much of its payout as ROC — deferring your tax while the underlying principal stays intact. NAV holding up while the checks keep coming is exactly the signature of constructive ROC.

GOF — the Guggenheim Strategic Opportunities Fund, a leveraged closed-end fund — is the cautionary case. It pays a distribution rate of about 17.6% on its market price (closer to 19% measured against NAV), a number that turns heads. But over the trailing year the fund’s total return on NAV was just 10.6%.

Run the arithmetic: paying roughly 19% on NAV while earning about 10.6% leaves an 8-point gap, and that gap is filled by handing back principal. The fund also carries about 18% leverage, which magnifies both the payout and the erosion, and it recently traded at a premium to NAV — investors paying more than a dollar for a dollar of a fund that is shrinking. The headline yield is real. The orchard behind it is getting smaller.

Same screen, same “high yield,” opposite outcomes. One label, two completely different economic engines — and only the NAV test separates them.

Your move this week

You don’t need a spreadsheet to apply this. You need four habits.

• Pull the NAV chart, not just the yield. Before you judge any high-payer, look at where its net asset value sits today versus a year and three years ago. A rising or flat NAV alongside a fat distribution is the green light. A steady grind lower is the warning.
• Treat a high ROC percentage as a question, not an answer. Ninety-six percent ROC can be brilliant tax management or slow liquidation. The NAV trend tells you which — the tax form never will.
• Compare the payout to what the fund actually earned. If the distribution rate sits far above the fund’s total return on NAV year after year, the difference is coming out of your principal. Be especially wary when a leveraged closed-end fund trades at a premium.
• Match the wrapper to the account. Constructive, ROC-heavy payouts defer tax and can be powerful in a taxable account; destructive ones erode principal in any account. Know which one you own before you reinvest.

A distribution is a decision about where your return comes from, not proof that it exists. Check the orchard before you cash the check.
