How Much Bloom Energy Stock Are You Really Betting On

You may not have bought this single clean energy stock, but if you own certain popular funds, you have quietly taken on a concentrated position.

The iShares Global Clean Energy ETF (ICLN) now holds about 14% of its assets in a single stock: Bloom Energy (BE), a company in the clean energy space. If you own that fund, or one of the 24 funds in our universe that hold it, you may have a much larger position in this one name than you ever intended. After a powerful run, it is worth taking a moment to see the exposure you never chose.

How Stretched Has It Become?

Bloom Energy has had a remarkable run. The stock now trades about 78% above its 200-day moving average, a common measure of its long-term trend. Over the past year, the stock has returned +1208%, with a gain of +118% in just the last three months. That performance has pushed its valuation to about 138 times its expected earnings for the year ahead, a multiple that assumes very strong execution on its forecast to grow profits about 87% a year. That high valuation reflects a lot of optimism, and some see new growth drivers on the horizon.

Which Of Your Funds Are Riding It?

The very concentration that is now a risk is what powered recent gains for some funds. The iShares Global Clean Energy ETF (ICLN) holds BE at about 13.7% of the fund, and has returned +47% over the past year. But the exposure is not limited to a single niche ETF. You will also find BE in broader funds, though at smaller weights. The Vanguard Russell 2000 ETF (VTWO) holds BE at about 1.8% of the fund, and the Schwab U.S. Mid-Cap ETF (SCHM) holds it at about 1.3%.

What A Pullback Would Actually Cost

This is not a forecast, but a transparent scenario to size the risk. If BE simply fell back to its 200-day average, the stock would drop about 44% from here. The impact on your funds would be direct. For the most exposed fund, iShares Global Clean Energy ETF (ICLN), that single stock's move would cause the fund to lose about 6.0% of its value. For the Vanguard Russell 2000 ETF (VTWO), the fund would lose about 0.8% from this one holding.

And here is the tax trap: you cannot surgically sell just Bloom Energy from inside your ETF. To reduce your exposure, you would have to sell the entire fund, which could trigger a taxable capital gain. This makes the position sticky, quietly compounding your risk.

A Way To Keep The Theme With Less Risk

You do not have to abandon the theme to dial back the concentration. For comparison, the iShares MSCI USA Momentum Factor ETF (MTUM) holds BE at about 0.8% of the fund, far less than the 14% in iShares Global Clean Energy ETF (ICLN). Its performance shows you can get broad exposure without the same single-name weight. Over the past year, MTUM returned +35%, versus +47% for ICLN.

The point is simply to make your hidden exposure visible. You may have bought a diversified fund, but you ended up with a concentrated bet. Knowing exactly how much you have riding on one name is the first step, and now you have a concrete example of how to carry less of it if you choose.

So, How Do You See Your Real Exposure?

Whether this is a name you are happy to keep riding or one you would rather not own quite so much of, the first move is the same: see your true exposure to it, then find funds that carry the same theme with less of any single stock. A fund's name tells you almost nothing about how concentrated it has quietly become.

Our ETF Valuation and Performance Scorecard ranks the major ETFs side by side on valuation, return, and risk, so you can see which funds lean hardest on a handful of names and which spread the exposure while keeping the performance.

A More Deliberate Way To Own The Upside?

And if the whole problem, a winner quietly growing into an outsized, hard-to-trim position you never sized on purpose, is something you would rather avoid by design, there is another way to think about it. An index fund holds whatever its benchmark dictates and never trims a winner for you, so concentration builds silently until a pullback does the trimming.

Our High Quality (HQ) Portfolio takes the opposite approach: rule-based, multi-factor selection across different kinds of businesses, re-balanced on a schedule, so winners get trimmed and no single name quietly becomes the whole position. 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.
