UNG is an exchange-traded fund intended to track daily Henry Hub natural gas price moves. It does not store physical gas. Instead, it buys NYMEX natural gas futures, mainly the front-month contract, then sells the expiring contract and buys the next month as expiration approaches. The fund charges a 1.06% expense ratio and holds about $508 million in assets. Natural gas futures frequently trade in contango, so the next month costs more than the expiring month. During each roll, the fund sells the cheaper contract and buys the more expensive one, creating a recurring drag that can reduce performance even when spot prices rise. Structural roll costs can be roughly 5% to over 15% annually, and fees add further headwinds.
"UNG is designed to track the daily price movement of Henry Hub natural gas. It does not store gas in tanks. It buys NYMEX natural gas futures, primarily the front-month contract, and as expiration approaches it sells that contract and buys the next month. The fund carries an expense ratio of 1.06% and roughly $508 million in assets. People hold it because they expect a winter cold snap, a hurricane in the Gulf, or a supply shock to push gas higher, and they want a clean, ticker-based way to express that view."
"Natural gas futures almost always sit in contango, meaning the contract for next month trades higher than the one expiring now. When UNG rolls, it sells the cheap expiring contract and buys the more expensive next one. That spread is a real cost, paid every single month, and it does not require natural gas prices to fall for the fund to bleed. A simple example: if the June contract is $2.80 and July is $2.95, the fund effectively buys fewer contracts for the same dollars."
"Repeat that drag twelve times a year and the math compounds against you. Industry roll-cost studies have pegged the annual structural drag at anywhere from 5% to north of 15%, depending on how steep the curve is. Add the expense ratio on top, and the fund has to fight a meaningful headwind just to stay flat. The decline is a story about how UNG is built: the fund holds front-month natural gas futures and rolls them every month, and the structure of the futures curve has been quietly eating shareholders alive."
"The clearest demonstration came this winter. Henry Hub spot gas spiked to $30.72 per MMBtu on January 23, 2026, a roughly tenfold jump from the prior month. By early Feb, UNG was still far below where it would have been if it simply mirrored spot gains, because the fund’s monthly futures roll kept forcing it to buy higher-priced contracts as the curve remained in contango."
