What Is the NYSE Arca Gold BUGS Index?

4 Min.

The NYSE Arca Gold BUGS Index tracks gold-mining companies. It uses a modified equal-dollar weighting method and focuses on companies with limited hedging of their forward gold production. The index also gives more weight to its three largest holdings and is reviewed and adjusted four times a year.


The NYSE Arca Gold BUGS Index, also called the HUI Gold Index, is an indicator for tracking brief fluctuations in gold prices. It comprises publicly traded gold-mining firms and is identifiable by the ticker symbols ^HUI or HUI, depending on your market information source. Established in March 1996, this index features companies that limit their gold production hedging to 18 months in advance. Consequently, these companies' index and share prices exhibit heightened responsiveness to short-term gold price variations.

Gold Mining Economics: Balancing Profit and Risk

Gold mining operations entail substantial investments in land rights, mining machinery, and labor force. Irrespective of gold price fluctuations, these investments remain relatively constant. Consequently, surges in gold prices can lead to significant profitability for mining companies, mainly when price spikes occur suddenly.

However, there is a risk of lower profits if gold prices fall below operational costs. To mitigate this risk, most gold miners employ hedging strategies, such as selling gold futures contracts, to secure a predetermined sale price for their gold. While these risk-mitigation measures shield against price drops, they may also limit the windfall gains associated with unforeseen surges in gold prices.

Advantages of the NYSE Arca Gold BUGS Index

For those who are risk-averse, investing in gold can be a risky venture. However, allocating funds to gold mining companies with limited hedging measures can prove enticing for investors with a higher risk tolerance.

The NYSE Arca Gold BUGS Index specializes in such relatively unhedged gold miners. The acronym BUGS reflects this focus, representing a "basket of unhedged gold stocks." This index employs a modified equal-dollar weighting approach, affording equal importance to all its constituents except for the three largest ones, which receive additional weighting. Quarterly reviews of the component companies occur in March, June, September, and December each year.

NYSE Arca Gold BUGS Index Criteria

Inclusion in the NYSE Arca Gold BUGS Index is contingent on specific criteria, encompassing market value, trading volume, and share price:

  1. The company must be listed on the New York Stock Exchange (NYSE), NYSE American, or Nasdaq.
  2. The current market capitalization must be at least $75 million (without free float adjustment).
  3. The trading volume over the preceding six months should not fall below 500,000 shares.
  4. The last traded price must exceed $3.00.

The Index Administrator retains the discretion to incorporate companies not meeting the minimum thresholds, with up to 10% of the index weight allowing for a market capitalization of at least $50 million and a minimum monthly volume requirement of 400,000 shares over the past six months.

It is worth noting that the NYSE Arca Gold BUGS Index, in contrast to the Philadelphia Gold and Silver Index (XAU), exclusively focuses on gold-mining stocks and does not encompass companies engaged in silver mining or hedging production beyond 18 months.

The NYSE Arca Gold BUGS Index Example

When it was first introduced, the index started at a value of 200. This value experienced a decline to 40 by December 2000, followed by a surge to nearly 575 in March 2011. In a more recent timeframe, from March 2020 to October 2020, the index exhibited substantial growth, nearly doubling from 160 to approximately 330.

It's important to note that direct investment or trading in the HUI or any index is not feasible. Nevertheless, the index can furnish valuable insights for analysis, aiding in identifying gold-mining companies exceptionally responsive to gold price fluctuations. As of January 2021, the NYSE Arca Gold BUGS Index prominently features three companies: Newmont Corporation (NEM), Barrick Gold Corporation (GOLD), and Yamana Gold Inc. (YRI.TO).


The NYSE Arca Gold BUGS Index, launched in March 1996, tracks gold-mining companies using a modified equal-dollar weighting system. It's sensitive to short-term gold price movements and is stringent in its inclusion criteria, emphasizing primary exchange listings. Historically, the index has experienced significant fluctuations, offering insights into gold-mining companies' responsiveness to gold price changes.
