Natural gas ETFs look like the easiest way to bet on the demand surge Porter Stansberry describes in his Boston Blackout presentation. Buy one ticker, get exposure to gas prices, done. The problem is that the easiest-looking vehicle in the natural gas market is also one of the most quietly punishing, and the reason has a name most retail investors never hear: contango.
Before the warning, the context. Stansberry’s thesis is that gas demand is about to jump. Gas already supplies more than 40% of American electricity and is the fastest baseload fuel to add when data centers need power immediately. The United States produces roughly 105 to 110 Bcf/d of dry gas, and the presentation points to about 50 Bcf/d of incremental demand from AI infrastructure. If that demand materializes, gas prices should rise, and an instrument that tracks gas prices should capture that move. That is the appeal of the ETF.
Here is what actually happens. A natural gas ETF does not hold gas. It holds futures contracts, and it rolls them each month as they approach expiration. When the futures curve is in contango, meaning later-dated contracts trade at higher prices than near-term contracts, the fund sells a cheap expiring contract and buys a more expensive one every month. That monthly roll is a recurring cost that bleeds the fund’s value over time.
This is not a small leak. The United States Natural Gas Fund, known by its ticker UNG, is the best-known vehicle in the space, and it has a long, well-documented history of underperforming the spot price of gas that it is supposed to track. Over any stretch where gas prices did not rise fast enough to overcome the roll cost, UNG fell while the underlying commodity looked fine. Leveraged products like BOIL, which aims for two times the daily move, and its inverse KOLD, compound that problem with daily rebalancing drag on top of the roll cost. UNL, which holds longer-dated contracts, smooths the curve a little but does not eliminate the issue.
This is exactly why Stansberry does not recommend an ETF for this trade. His three picks are individual stocks: Venture Global, EQT, and Viper Energy. Each is a business, not a bet on the spot price. Venture Global is the LNG exporter that liquefies American gas and sells it overseas at premium prices. EQT is the largest natural gas producer in the country. Viper is the royalty company that collects a share of Permian production without paying drilling costs. These are equity claims on cash-generating businesses, so they compound earnings and free cash flow over time rather than fighting a monthly roll.
The equity approach also sidesteps a second ETF problem: even when gas does rise, the businesses may rise more, because they add operating growth on top of the commodity move. An exporter growing revenue 59% year over year, as Venture Global did recently, is capturing a spread between cheap American supply and expensive global demand, not just a single price.
That does not mean ETFs are useless. For a short-term, tactical trader who can time a spike, they are a legitimate tool. For an investor holding for months or years, the contango math usually works against you. The honest guidance is that most people who want the Boston Blackout thesis are better served by the stocks than by the fund that tracks the gas. We compare those stocks in our best natural gas stocks and natural gas stocks to buy pieces, and we cover the futures market separately for the same reason.

A simple way to see the contango cost
Imagine gas costs $3.00 per MMBtu for the front-month contract and $3.20 for the next month out. A fund that must roll sells its $3.00 contract and buys the $3.20 one, locking in a loss of about 6.7% on that single roll. If the spread persists, the fund gives up roughly that amount month after month before gas has moved at all. Gas has to rally faster than the roll cost just for the fund to break even.
That is why the fund’s price chart can look nothing like the price of gas over a year. The spot commodity can be flat or slightly up while the ETF grinds lower, simply because the roll cost ate the return. Leveraged products make it worse. A two times fund like BOIL resets its exposure daily, so it compounds short-term moves rather than tracking a two times return over any longer period. Over weeks or months, that daily reset can produce results that surprise holders who expected a straight double.
The takeaway is not that these funds are broken. They do what they are built to do, which is track daily or short-term moves. The takeaway is that they are trading tools, not investment vehicles, and that is a distinction worth internalizing before you commit real money.
