United States Natural Gas Fund (UNG ETF): How to Buy

The United States Natural Gas Fund (UNG -3.58%) allows investors to track the daily price movements of natural gas. The fund holds futures contracts and other derivatives to provide investors with a way to make a short-term directional bet on the price of natural gas.

The fund makes it easy to bet on the thesis that the price of natural gas in the U.S. will move meaningfully in the short term. Traders can make this gamble without needing to open a commodity futures account and learn how to trade futures. They also don't need to risk investing in a natural gas stock that might underperform the price of gas in the near term.

However, the United States Natural Gas Fund also has serious drawbacks. The costs of rolling natural gas futures contracts forward (and the fund's expense ratio) eat into its returns over the long term, so this fund is only suitable for a short-term trade.

This guide will show you everything you need to know about the United States Natural Gas Fund and teach you how to invest in ETFs for beginners.

What is it?

What is the United States Natural Gas Fund?

The United States Natural Gas Fund is an exchange-traded security similar to an exchange-traded fund (ETF). It primarily invests in natural gas futures contracts. The fund will also hold other natural gas-related futures contracts, forwards, and swap contracts. It collateralizes these contracts with cash, cash equivalents, and U.S. Treasury bonds with remaining maturities of less than two years.

The fund aims to track the daily price movements of natural gas. It benchmarks its returns against futures contracts traded on the New York Mercantile Exchange (NYMEX) that expire in the next month and have at least two weeks until expiration.

The fund has a couple of notable benefits. It provides investors exposure to natural gas without knowing how to invest in futures contracts. It also enables them to bet directly on natural gas instead of investing in a natural gas stock, which might not move in the same direction as gas prices.

However, it also has some major drawbacks. The fund needs to roll its futures contracts forward as they near expiration, which eats into returns (expiring contracts tend to have a lower price than those with more time until expiration). In addition, fees (from rolling contracts and fund management costs) eat into the fund's returns.

Because of these issues, this fund is unsuitable for long-term investment. It's best for making a short-term trade to potentially profit from an expected near-term rally in the price of natural gas.

Dividends

Does the United States Natural Gas Fund pay a dividend?

The United States Natural Gas Fund does not pay a dividend. The fund invests primarily in natural gas futures contracts expiring in a month, which don't generate any income. The fund's purpose is as a short-term investment vehicle to make a bet on the near-term price movement of natural gas.

Expense ratio

What is the United States Natural Gas Fund's expense ratio?

Fund managers charge fees, known as the expense ratio, to execute their investment strategy on behalf of investors. This fund has a total expense ratio of 1.01%. That's a very high expense ratio due in part to the management oversight required to roll futures contracts forward each month.

To put the expense ratio into a different context, every $1,000 invested in the fund would cost $10.10 annually. The fee would really add up over the long term, which has contributed to its poor historical performance.

Historical record

Historical performance of the United States Natural Gas Fund

Futures trading is very challenging. That's evident in the performance of this fund over the years:

The sole factor driving those poor long-term returns is the fund's expenses (expense ratio and the cost of rolling natural gas futures contracts). Given its underperformance, this fund is unsuitable as a long-term investment.

However, the fund does a much better job of tracking the movement in the price of natural gas in the short term. For example, gas prices have surged in the past year, driving a big increase in the value of this fund:

Given this dynamic, investors should buy this fund only when they firmly believe the price of natural gas will spike over a short period (due to a winter storm or other catalyst).
