What Is CORO? iShares International Country Rotation Active ETF
Last updated October 2026
Short answer
CORO is iShares International Country Rotation Active ETF, an ETF that tracks Actively managed, no tracked index at a 0.55% expense ratio. CORO does not hold companies. It holds other iShares funds, and shifts between them according to BlackRock's view on which countries to favour. As of October 2026 Japan is the largest allocation at 19.5 percent through the country ETF, followed by Canada at 12.8 percent and Switzerland at 8.3 percent. One position stood out in August for a fund labelled international: 4.0 percent in an S&P 500 ETF, which has since dropped out of the ten largest holdings. The fee is 0.55 percent, the fund launched in 2024 and it has gathered about $12.8 billion, including a single day of $4.2 billion in inflows on September 24, 2026. The trailing yield is 2.15 percent.
CORO is issued by iShares and tracks Actively managed, no tracked index. It charges a 0.55% expense ratio, holds approximately $12.8B in assets under management, yields about 2.15%, and launched in 2024.
A fund of funds, with room for a US position
Nine of the ten largest holdings are iShares country ETFs. As of October 2026 they are Japan at 19.5 percent, Canada at 12.8, Switzerland at 8.3, Spain at 6.7, South Korea at 6.2, the United Kingdom at 5.5, Sweden at 5.0, Taiwan at 4.9 and Hong Kong at 4.0. The tenth is Taiwan Semiconductor held directly at 4.9 percent, which sits alongside the Taiwan country fund. The structure is deliberate: rotating between countries is far easier to implement with liquid country ETFs than by trading hundreds of individual foreign listings.
The S&P 500 position, 4.0 percent in August and no longer among the ten largest in October, is the line that deserved attention. A fund named for international country rotation holding a US index fund means the mandate permits the manager to park capital in the United States when no international market looks preferable, or to use it as a liquid holding between allocations. Neither is unreasonable, but an investor building a portfolio with a fixed US and international split needs to know that a portion of their international sleeve may be sitting in US large caps.
Taiwan arrives through two routes. The country ETF at 4.9 percent plus Taiwan Semiconductor held directly at 4.9 percent gives roughly 9.9 percent of the fund tied to one market, and a meaningful share of that to one company, since Taiwan Semiconductor is also the dominant weight inside the country fund. Combining the two lines gives a truer picture than reading them separately.
What country rotation is betting on
The premise is that country returns diverge widely and predictably enough to be worth trading. That first part is uncontroversial: in any given period the gap between the best and worst performing developed markets is large, driven by currency moves, commodity exposure, central bank policy and the sector composition of each market. Korea is a semiconductor market, Canada is energy and banks, Switzerland is pharmaceuticals and staples. Choosing between them is choosing between industry exposures with a flag attached.
The second part, whether those divergences can be anticipated well enough to cover costs, is the open question and the reason the fee is 0.55 percent. That is several times what a broad developed-market index fund charges, and the rotation has to add more than that difference for the approach to have been worthwhile. It is a bet on the manager, and the fund's 2024 launch means there is very little record to assess.
The top ten positions come to about 77.8 percent of assets, which tells you this is a concentrated set of country calls rather than a lightly tilted index. When Japan is 19.5 percent and Canada 12.8 percent, the fund's behaviour is dominated by two markets. That concentration is the point of an active rotation strategy, but it is the opposite of what most investors expect from a diversified international fund.
The rotation has been visible since August. The United Kingdom fell from 10.9 percent to 5.5 percent and South Korea from 9.5 percent to 6.2 percent, while Switzerland rose from 4.8 percent to 8.3 percent and Sweden and Hong Kong entered the top ten. China and the S&P 500 fund left it. Assets jumped from about $7.8 billion to $12.8 billion, helped by a $4.2 billion inflow on a single day in late September. As of October 16, 2026 the price was up 13.4% year to date and 17.0% over one year, which is still a short record for judging a strategy whose case rests on years of country calls.
Where it fits and what to check
The gap it fills is real. Most investors hold international equity through a single market cap weighted fund, which allocates by the size of each market rather than by any assessment of it, and which therefore holds the most of whatever has already risen. A rotation strategy is an attempt to break that link. Whether it succeeds is unproven here, but the problem it addresses is genuine.
It is a poor fit for anyone wanting predictable international exposure, for tax-sensitive accounts where turnover matters, or as the sole international holding in a simple portfolio. The country weights can change substantially, so the geographic profile an investor buys today may not be the one they hold next year. That is inherent to the design rather than a flaw.
Two things are worth checking before use. First, the total cost including any fees embedded in the underlying funds, since a fund of funds structure can carry expenses at both levels depending on how the manager handles it. Second, how the US position is treated in the mandate, because a persistent allocation to US large caps inside an international fund affects the overall portfolio balance in ways an asset allocation spreadsheet will not catch.

FAQ
What does CORO actually own?
+
Mostly other iShares ETFs, each representing a single country or market. As of October 2026 the largest are Japan at 19.5 percent, Canada 12.8, Switzerland 8.3, Spain 6.7, South Korea 6.2, the United Kingdom 5.5, Sweden 5.0, Taiwan 4.9 and Hong Kong 4.0. It also holds Taiwan Semiconductor directly at 4.9 percent. In August an S&P 500 ETF at 4.0 percent was among the ten largest positions; it no longer is. Using country funds rather than individual shares makes reallocating between markets far simpler to execute.
Why does an international fund hold the S&P 500?
+
The mandate permits it, most likely as a liquid holding when no international market is preferred or as a temporary position between allocations. At 4.0 percent in August it was not a large position, and it has since fallen out of the top ten, but the permission matters for anyone maintaining a deliberate split between US and non-US equity, since part of what they classify as international exposure can be invested in US large companies at the manager's discretion.
How much Taiwan exposure does the fund have?
+
More than the country ETF line suggests. As of October 2026 the Taiwan fund is 4.9 percent and Taiwan Semiconductor is held separately at 4.9 percent, giving roughly 9.9 percent tied to that market. Since Taiwan Semiconductor is also the largest constituent inside the country fund, the effective exposure to that single company is higher than either line shows on its own.
Is 0.55 percent expensive?
+
It is several times the cost of a broad developed-market index fund and in line with other active international strategies. The rotation approach has to add more value than that difference for the fee to have been worth paying. Because the fund launched in 2024, there is not yet enough history to judge whether it does, so the fee is currently a known cost against an unproven benefit.
How concentrated is the fund?
+
The ten largest positions come to about 77.8 percent of assets as of October 2026, with Japan alone at 19.5 percent and Canada at 12.8 percent. That is a set of deliberate country calls rather than a broadly spread international portfolio. Investors expecting the diversification profile of a global index fund will find something quite different, and the concentration can shift as the manager reallocates.
Does the country mix stay stable?
+
No, and it is not intended to. The strategy reallocates between markets as the manager's assessment changes, so the geographic profile visible today may look materially different in a year. For portfolio construction that means CORO cannot be treated as a fixed regional allocation, and anyone tracking country exposure across a whole portfolio needs to re-check it periodically.
Does a fund of funds structure mean paying fees twice?
+
It can, depending on how the manager handles fees on the underlying funds. When a firm holds its own products, it commonly waives or rebates the acquired fund fees so investors pay only the top-level charge, but the arrangement should be confirmed in the fund documents rather than assumed. This is the most important cost question for any fund built from other funds.
What does country selection actually decide?
+
Largely industry exposure and currency. Korea is dominated by semiconductor and heavy industrial companies, Canada by energy and banks, Switzerland by pharmaceuticals and staples, the United Kingdom by energy, banks and consumer goods. Choosing between countries is therefore closer to choosing between sector mixes and currencies than to a view on national economies, which is worth keeping in mind when assessing the strategy.
What is CORO's expense ratio?
+
CORO has an expense ratio of 0.55% per year as of October 2026, charged by iShares and deducted from the fund's value rather than billed to you separately. On a $10,000 position that is roughly $55 a year. Fees compound over time, so on a long-term holding the expense ratio is one of the few return drivers you control. It is worth comparing against other funds that track Actively managed, no tracked index before you choose.
How do I compare CORO to similar ETFs?
+
Put a few fields side by side: the expense ratio (fees compound over decades), the index or strategy it tracks, the top holdings and how much they overlap with what you already own, the dividend yield, and the AUM, liquidity, and bid-ask spread that affect trading costs. For index funds, tracking error (how closely it follows its index) and tax efficiency matter too. CORO's figures are above; the full method is in Walnut's guide on how to compare ETFs.
