JEPI vs VOO: What a One-Third Overlap Says About Income ETFs
JEPI overlaps VOO by only about a third despite sharing dozens of holdings. The gap explains what a covered-call income fund actually changes in a portfolio.

Covered-call income funds are usually pitched as a way to earn yield from large-cap U.S. stocks. That framing invites an obvious question: if the underlying exposure is large-cap U.S. equity, is an income fund just an expensive S&P 500 fund with a distribution attached?
The data says no. The live JEPI vs VOO comparison puts the weighted overlap between the JPMorgan Equity Premium Income ETF and the Vanguard S&P 500 ETF at 32.39% across 97 shared holdings — a Moderate Overlap verdict.
Roughly a third duplicated, two thirds not. That split is worth understanding before deciding whether the fund belongs alongside your core.
Why the Overlap Lands Near a Third
Three things pull the score well below what "large-cap U.S. equity" would imply.
The stock selection is active, not indexed. JEPI builds a portfolio of large-cap names chosen for low volatility and risk-adjusted return characteristics, not a replication of the S&P 500. Many of the index's most dominant positions are deliberately held at far smaller weights, or excluded.
The weighting is far flatter. VOO's largest holding can approach 8% of the fund. An income strategy focused on volatility reduction spreads capital much more evenly. Under the weighted formula only the smaller weight counts:
Overlap = Σ min(weight in JEPI, weight in VOO)
A company held at 7.5% in VOO and 1.5% in JEPI contributes 1.5 points, not 7.5. Across the megacap complex, that discards most of what drives VOO's returns.
Part of the portfolio is not stock at all. The option-linked instruments that generate the fund's income have no counterpart in an index fund, so that portion of the portfolio cannot overlap with anything VOO holds.
What This Means in Practice
A Moderate Overlap score is the most interesting kind, because it means the answer is genuinely "partly."
- It is not a replacement for a core holding. Two thirds of the portfolio differs from VOO, and much of that difference is the deliberate absence of megacap concentration — the same concentration that has driven index returns.
- It is not redundant either. 32.39% is low enough that JEPI is contributing distinct exposure, not repeating your index fund with extra fees.
- The trade is upside for income. Writing calls caps participation in strong rallies in exchange for premium. The overlap score quantifies the equity portion; it says nothing about that payoff asymmetry, which is the actual decision.
- Cost and tax treatment matter more here. Active management and option income carry a materially higher expense ratio than an index fund, and distributions are often taxed less favorably than qualified dividends. In a taxable account that gap compounds.
Calibrating Against Other Pairs
| Pair | Overlap | Interpretation |
|---|---|---|
| VOO vs IVV | 97.16% | Same index, same method — one exposure |
| RSP vs VOO | 46.49% | Same index, different weighting |
| JEPI vs VOO | 32.39% | Same asset class, different objective |
| SCHD vs VYM | 18.89% | Same theme, different screen |
Note where JEPI lands relative to RSP. An equal-weight S&P 500 fund — holding literally the same 502 companies as VOO — overlaps more than a covered-call fund does. Weighting and objective, not asset class, determine how much of a portfolio is genuinely duplicated.
How to Evaluate an Income Sleeve
- Measure the income fund against your core holding first, then against your other income positions.
- Read the weighted score, and treat 97 shared tickers as the less informative number.
- Separate two questions: how much equity exposure is duplicated (the overlap score answers this) and whether the income strategy's payoff profile suits you (it does not).
- Check the tax location. Income-heavy strategies generally sit better in tax-advantaged accounts.

Conclusion
At 32.39% overlap, JEPI is neither a substitute for a core index fund nor a duplicate of one. It is a different objective wearing a familiar asset class — and the overlap score is what separates those two readings.
