The HUI Index monitors a list of the 16 largest gold-producing companies. The list is weighted to give greater account to the three companies with the highest market capitalization. The full list is updated quarterly. As mentioned earlier, the 16 companies included do not cover their funds for more than 18 months.
For those looking for a longer-term investment, a Gold IRA broker can provide a secure and reliable option. The HUI was released on March 15, 1996 by the United States Stock Exchange (AMEX) and was originally known as the AMEX Gold BUGS Index. BUGS is the acronym for “Basket of Unhedged Gold Stocks”. Through a process of several stock mergers and acquisitions over time, the HUI is now known as the NYSE Arca Gold BUGS Index. These additional questions are not HUI questions and therefore do not appear in the HUI2 or HUI scoring algorithms.
Figure 1 illustrates the components of the HUI that show the flow of information about a subject of the study collected using a questionnaire, by deriving health status attribute levels and utility scores, to estimate quality-adjusted years of life (QALY). The multiplicative form captures important preference interactions between health states and has been shown to accurately predict the average scores of an independent sample, one of the main purposes of the HUI. The widespread use of the HUI facilitates the interpretation of the results and makes it possible to compare the results of the disease and treatment, as well as to compare long-term sequelae at the local, national and international levels. The NYSE Arca Gold BUGS Index, better known as the HUI Gold Index, is an index of publicly traded gold mining companies that is useful for tracking short-term trends in gold prices.
HUI questionnaires are designed to ask the minimum number of questions in order to classify a subject's health status according to the HUI2 and HUI3 systems. According to the official ICE methodological document, the HUI is “designed to measure the performance of companies involved in the extraction of gold ore”. The clinic uses an internal computer system to manage the HUI questionnaires and report, using graphs and tables, on current measurements of the patient's health status. Gold mining stocks that may be included in the HUI must be listed on the New York Stock Exchange or the “NYSE American” or listed on the NASDAQ.
Since it only includes mining companies that do not employ hedging, the HUI has a higher correlation with the spot price of gold than the XAU. The grants consist of the use of a standard HUI instrumentation package at no cost to the recipient, subject to certain conditions. Unlike the equally weighted HUI, the NYSE Arca Gold Miners Index (GDM) is a market capitalization-weighted index that includes “publicly traded companies” that are primarily engaged in the extraction of gold and silver in locations around the world. The derived levels are then combined with utility functions to calculate utility scores for a single attribute and an HRQL score for the HUI2 and HUI3 systems.
Although you cannot invest or trade directly in the HUI or in any index, it can provide you with information to use in your analysis, for example, identifying gold mining companies that may be especially sensitive to changes in gold prices.
