What does a repurchase ETF actually hold?
A repurchase ETF selects and weights US-listed stocks based on some measure of share repurchase activity — most commonly (a) recent 12-month gross dollars spent on repurchases or (b) a "repurchase yield" ratio (repurchases / market cap). Some funds combine repurchase metrics with additional filters like dividend yield or valuation.
Important note: a repurchase ETF is not the same thing as an ETF that does repurchases. Every US-listed ETF is a passive vehicle. "Repurchase ETF" refers to the selection methodology — repurchase-activity-based stock picking — not to any repurchase of ETF shares themselves.
The main US repurchase ETFs
The largest and longest-tenured US repurchase-strategy ETFs at the time of writing:
- Invesco Repurchase Achievers ETF (PKW) — one of the earliest repurchase ETFs, launched in 2006. Tracks the NASDAQ US Repurchase Achievers Index, which requires companies to have reduced share count by at least 5% over the trailing 12 months. Large- and mid-cap weighted; small-cap coverage is minimal.
- Pacer US Cash Cows 100 ETF (COWZ) — not strictly a repurchase fund but heavily overlapping. Selects for free cash flow yield, which correlates strongly with repurchase capacity.
- iShares MSCI USA Value Factor ETF (VLUE) — value factor overlap; not repurchase-specific but includes repurchase yield in some methodology variants.
Where do repurchase ETFs underweight what you want?
The main US repurchase ETFs are structurally weighted toward mid- and large-caps, for two reasons:
- The index construction rules typically require minimum market cap thresholds ($500M+) or minimum trading volumes that many small-caps don't meet
- Weighting methodologies (market-cap-weighted, or modified market-cap-weighted) push allocations toward the biggest names in the repurchase universe, further diluting small-cap exposure
This matters because the academic evidence (Ikenberry-Peyer-Vermaelen and successors) has consistently shown the repurchase anomaly is strongest in small-caps — precisely where the major repurchase ETFs are structurally underweight.
The DIY alternative
Building your own small-cap repurchase screen produces exposure the ETFs can't. The core filters:
- Market cap: $1M-$300M (or your preferred small-cap range)
- Trailing 12-month repurchase yield: above 5%
- Net share count change: reducing (confirms repurchases aren't offset by issuance)
- Free cash flow yield: above the repurchase yield (ensures the program is self-funding)
- Long-term debt growth: less than the annual repurchase amount (ensures the repurchase isn't debt-funded)
The resulting universe is typically 30-60 names. Position-sizing this yourself gives you the small-cap exposure the ETFs don't. See our repurchase yield methodology for details.

The case for a repurchase ETF over DIY:
- You want factor exposure without single-name risk
- You want an inside-a-401(k) or IRA-friendly vehicle without individual position management
- You want liquidity for tactical allocation
- You want mid- and large-cap repurchase exposure specifically (which the ETFs give you)
The case against:
- You want small-cap concentration (where the anomaly is strongest)
- You want to combine repurchase metrics with value factor (P/B, P/E) filters ETFs don't apply
- You want to hold names for the full authorization execution cycle, not rebalance quarterly
- You want to exclude names that are simultaneously running ATM dilutive issuance
Cost comparison
| Vehicle | Expense ratio | Small-cap allocation | Repurchase yield filter |
|---|---|---|---|
| PKW (Repurchase Achievers) | ~0.62% | <5% | Yes (share count reduction ≥5%) |
| COWZ (Cash Cows) | ~0.49% | <10% | Indirect (FCF yield) |
| DIY screen | 0% ongoing | Configurable | Configurable |
Whether repurchase ETFs still work
Academic research has continued to find a positive premium associated with repurchase-based stock selection, though the effect has narrowed in large-caps as index-arbitrage flows have become more efficient at pricing in announcements. The small-cap effect has been more persistent — which is why concentrating exposure there tends to matter more than which specific vehicle you use.
Frequently asked questions
What is the biggest repurchase ETF?
By assets under management, the Invesco Repurchase Achievers ETF (PKW) is the largest US repurchase-strategy ETF. Its methodology requires companies to have reduced net share count by at least 5% over the trailing 12 months.
Do repurchase ETFs pay dividends?
Yes, most repurchase ETFs distribute the dividends they receive from the underlying holdings, typically quarterly. The yield is modest because the underlying companies are typically returning capital via repurchases rather than dividends.
Are repurchase ETFs actively managed?
The main US repurchase ETFs are passive vehicles tracking rule-based indices with quarterly or semi-annual rebalancing. They are not actively managed in the discretionary sense, but the underlying index rules do produce active-style factor tilts.
Should I buy a repurchase ETF or individual stocks?
The trade-off is diversification vs concentration. A repurchase ETF gives you factor exposure without single-name risk but structurally underweights small-caps where the repurchase anomaly is strongest. A DIY screen with 20-40 individual small-cap names gives you the concentrated exposure but requires ongoing management.
Is a repurchase ETF better than a dividend ETF?
Different exposures, different tax profiles. Dividend ETFs distribute more current income (taxed as income for most US investors); repurchase ETFs let gains compound as capital until sale (typically taxed at lower long-term capital gains rates). Neither is universally 'better' — the choice depends on your tax situation and income needs.
Do repurchase ETFs include international stocks?
The largest US-listed repurchase ETFs focus on US-domiciled companies. Global repurchase strategies exist but are less common; the underlying data (real-time global repurchase disclosures) is harder to aggregate than US SEC EDGAR filings.
