What ICLN’s Concentrated Holdings Say About This Dip

This clean energy fund’s history shows that buying a discount often means enduring more downside first.

The last time the iShares Global Clean Energy ETF (ICLN) saw a significant drop was in April 2025, and what followed was anything but a simple, straight-line recovery. If you own ICLN today, you’re looking at a similar picture: the fund is down about 19.8% from its recent high, and that red number in your portfolio forces a decision. Is this a chance to buy more at a discount, or is it a warning sign?

For some funds, a dip is a gift. For others, it’s a trap. The difference often comes down to what the fund holds, and ICLN’s own history offers a clear, if cautionary, lesson.

How Often Has A Dip Like This Paid Off?

Let’s be direct. Based on its track record, buying a steep drop in ICLN has not been a consistently winning move. Since 2008, the fund has experienced 15 similar declines of 20% or more. Of those 15 instances, only 6 were followed by a positive return over the next twelve months. The median outcome for a dip buyer a year later was a return of negative 1%.

That’s not to say a rebound is impossible. The fund’s history shows a wide range of outcomes. But the record suggests that a recovery is far from automatic. The question is, what did investors have to endure to capture any potential upside?

The Price of Patience Was More Pain

Even when the fund did eventually bounce, the ride was rarely smooth. The median worst further drawdown after buying a dip was 17%. That means a typical investor who bought after a 20% drop had to stomach another 17% decline before the fund found a bottom. We saw this pattern play out after dips in August 2023 and again in early 2025.

While the median peak gain within a year was +23%, that gain came at the price of significant additional volatility. This isn’t the kind of dip that has historically healed quickly or cleanly.

Why This Basket Doesn’t Always Bounce

The fund’s construction helps explain its volatile recovery record. Unlike a broad market index, ICLN is a concentrated, thematic fund. It holds 105 positions, but its fate is tied to a much smaller group of companies. The five largest holdings make up 40% of the fund, and the top ten account for 54%.

When top holdings like Bloom Energy (BE) or First Solar (FSLR) are in favor, the fund can perform well. But when the clean energy sector as a whole faces challenges, there are few places to hide within this basket. This pattern is common in funds focused on a specific theme. For another perspective on how a concentrated fund’s history can look, consider the record of other thematic ETFs.

Ultimately, buying this dip isn’t a bet on a statistical bounce. It’s a decision based on your conviction in that specific, concentrated portfolio of clean energy stocks. The fund’s own history suggests that conviction will be tested, with a real possibility of further downside before any meaningful recovery takes hold.

Should You Be Buying This Dip?

With ICLN in the red, the instinct is to treat the discount as a gift and buy more. The history above is a real reason for caution before you do. We know what you are thinking, and it is an absolutely fair question.

Still, a dip-and-recovery record is only half the story. It tells you what tended to happen after past drops, not whether the fund is reasonably valued today or how it is holding up against its peers right now. Before adding to a position, it is worth seeing where it actually stands: our ETF Valuation and Performance Scorecard lines the major ETFs up side by side on valuation, returns, and risk, so the dip becomes one input rather than the whole decision.

The Fund Diversifies. Does The Rest Of Your Wealth?

A fund like this spreads risk by design – which makes it easy to forget the single stock sitting outside it that has quietly grown into a large share of your net worth. That one position is the real exposure, and selling it to diversify hands a slice of the gains to the IRS. There is a way to cap its downside and unwind it tax-efficiently.
