What ICLN’s Basket Says About Buying This Dip
The fund’s history of deep drops comes with a serious warning for anyone tempted by the current discount.
The last time the iShares Global Clean Energy ETF (ICLN) saw a steep drop was in April 2025, one of several recent tests for investors. With the fund now sitting about 18.6% below its 52-week high, you might be looking at the discount and wondering if now is the time to add more. Is this a gift, or is it a trap?
For any fund, the answer depends on what’s inside. A broad, diversified basket tends to find its footing after a fall. A concentrated, single-theme fund can stay down for a long, long time. The history of ICLN itself suggests buying its dips is anything but a sure thing.
A Record That Flashes Caution
Let’s look at the fund’s own track record. Since 2008, ICLN has experienced a deep dip, defined as a drop of 20% or more within 180 days, on 15 separate occasions. Of those 15 instances, the fund managed a positive return over the following year just 6 times. That’s a recovery rate of less than half.
The returns themselves tell a sobering story. The median return in the twelve months after one of these dips was negative 1%. While the outcomes have ranged widely, from a painful negative 40% to a powerful +169%, the typical experience for a dip buyer has been a small loss a year later. Episodes like the drops in August 2023 and April 2023 serve as concrete reminders of this challenging history.
The Price of Admission Was More Downside
Even when a rebound eventually arrived, it rarely started the day you bought the dip. The fund’s history shows that the median worst further drawdown in the year after a dip was 17%. That’s the additional decline a buyer typically had to stomach before the fund found a bottom. That’s a steep price to pay for entry.
For those who held on, the median peak gain within a year of a dip was +23%. But getting there meant enduring a significant risk of further losses first. The question is whether that potential gain justifies weathering another 17% drop on the way down.
A Concentrated Fund, Not A Broad Bet
So why doesn’t this fund bounce back like the broader market? Because it isn’t the broader market. While it holds 105 positions, it’s a highly concentrated portfolio. The five largest holdings make up 40% of the fund, with names like Bloom Energy and First Solar carrying significant weight. The top ten positions account for 54% of the assets.
This isn’t a flaw; it’s the fund’s design. It provides focused exposure to the clean energy industry. But it means the fund’s fate rests on a relatively small group of companies in a single sector. This dynamic, where a fund’s concentrated nature shapes its dip-and-recovery profile, is not unique to clean energy. For another perspective on a thematic fund, you can read about the history of a well-known innovation ETF.
Ultimately, the fund’s own record suggests buying a dip like this one has historically been a difficult proposition. The path has often included a steep further drop before any recovery. The decision today isn’t about market timing, but whether you believe this specific basket of clean energy stocks has a fundamental reason to reverse its trend and outperform its own history.
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.
What A Dip Chart Cannot Tell You
There is also a limit no dip chart can fix. An index fund has to hold whatever its index dictates, so a buyer can end up with money concentrated in a handful of the same names, whether or not they would have chosen them. Buying the dip does not change what is inside the basket.
If you would rather your exposure be chosen than inherited, our High Quality (HQ) Portfolio is built on a different idea: rule-based, multi-factor screening instead of index membership, with 30 names spread deliberately across different kinds of businesses and re-balanced on a schedule so it leans into quality while trimming what has run. It has a record of outpacing a benchmark that combines the three major indices – the S&P 500, S&P Mid-cap, and Russell 2000.
