It is generated by the large language model of Penghua Wenxin

In the first two sharing, the Penghua Wenxin model introduced the basic concept of index funds to Pengyou, in fact, there is a type of index fund in the market, which specializes in investing in stocks in a certain industry, that is, industry index funds. The investment risk of industry indices is higher, and investors need to consider the investment value, as well as the characteristics of different industries and the stage of development they are in. Starting this week, the large model will lead Pengyou into various industries, introducing two different industry indices in each issue and exploring the investment logic behind the industry index.

What are the criteria for the classification of A-share market industries?

There are many main criteria for the classification of the A-share market, among which the more common ones include the standards issued by the China Securities Regulatory Commission, China Securities Index Company, Shenwan, CITIC, Dongcai, Wind, Flush, etc. These standards classify A-share listed companies into industries according to different bases and purposes.

Among them, the classification standard of CSI is more common in index investment and fund tracking, which divides industries into first, second, third and fourth industry classifications, so as to facilitate a more detailed understanding and analysis of the characteristics and performance of each industry.

In addition, the China Association of Public Companies has also issued the Guidelines for the Statistical Classification of Listed Companies by Industry of the China Association of Public Companies, which classifies listed companies by industry and provides a set of corresponding classification codes to facilitate investors and researchers to quickly and accurately obtain information and data from various industries.

At present, the vast majority of the indexes tracked by the fund in the market are mainly indexes released by China Securities Index Company and China Securities Index Company, and the industry classification standard of China Securities Index Company is a four-level classification, with ten first-level industries, namely: 00 energy, 01 raw materials, 02 industry, 03 optional consumption, 04 major consumption, 05 medicine and health, 06 financial real estate, 07 information technology, 08 telecommunications business, and 09 public utilities.

A brief overview of the definition and classification of the energy industry

Energy, also known as energy resources or energy resources, is the key material basis that supports the operation of the national economy. A country's ability to control its energy resources largely determines its future destiny. The level of energy development and utilization and per capita consumption are not only the embodiment of the progress of production technology, but also an important indicator to measure the level of people's living standards.

There are two main categories of energy: primary energy and secondary energy.

1. Primary energy

A. Definition: An unprocessed energy resource in nature that exists in its original form.

B. Classification:

Renewable energy: such as hydropower, wind energy, biomass energy, etc., which can be generated sustainably and will not be depleted or have a serious impact on the environment.

Non-renewable energy sources: such as coal, oil, natural gas, etc., these energy reserves are limited and cannot be regenerated once depleted. Coal, oil and gas are at the heart of the global energy system.

In addition, primary energy includes other forms of renewable energy such as solar, geothermal, and ocean-based energy.

2. Secondary energy

A. Definition: An energy product obtained from the processing and conversion of primary energy.

B. Examples: electricity, gas, gasoline, diesel, coke, clean coal, laser, biogas, etc. These energy sources are directly or indirectly converted from primary energy and have different forms and uses of energy.

In the process of energy utilization, primary energy and secondary energy are interdependent and complementary to each other, and together constitute the energy system of human society. With the progress of science and technology and the improvement of environmental awareness, the proportion of renewable energy in the energy structure has gradually increased, which has become an important trend in global energy development. As the world's largest energy producer and consumer, China is an indispensable and important part of the world energy market, and is playing an increasingly important and positive role in maintaining global energy security.

What are the representative indices of the energy sector?

There are many representative indices in the energy sector that can help investors understand and track the performance of the energy market. Here are some of the major energy sector indices:

1. New energy index: With the rise of renewable energy, the new energy index has received more and more attention. These indices typically cover renewable energy companies such as wind, solar, and biomass.

2. Oil & Gas Indices: These indices primarily track the performance of oil and gas exploration, production, and service companies. Since oil and gas account for an important position in global energy consumption, these indices have a significant impact on the energy market.

3. Coal Index: The Coal Index focuses primarily on coal mining, production, and related service companies. Although the share of coal in the energy mix is gradually declining, it is still an important source of energy in some regions and countries.

4. Energy Equipment & Services Index: This index covers companies that provide equipment and services to the energy industry, including services such as drilling, logging, completion, production optimization, and energy transmission and storage equipment.

5. Composite Energy Index: This type of index usually includes companies with multiple energy types, such as oil, natural gas, coal, renewable energy, etc., to provide a comprehensive view of the entire energy market.

It is important to note that specific energy indices may vary by region, exchange and index provider. When choosing an energy index, investors should weigh it according to their investment objectives and risk tolerance.

In addition, with the rapid development of the new energy industry in recent years, some emerging new energy theme indices have gradually attracted attention, such as the photovoltaic industry theme index, the battery industry theme index, the new energy vehicle industry theme index, etc. These indices provide investors with more granular investment options and help capture development opportunities in the new energy industry.

What is the investment logic of the energy sector index?

The investment logic of the energy sector index is mainly based on the following aspects:

1. Energy demand growth: With the development of the global economy and the growth of population, energy demand is also rising. This growth provides a broad market space and development opportunities for the energy industry, making the energy industry index a long-term investment value.

2. Energy transition: Under the pressure to combat climate change and reduce carbon emissions, the global energy mix is undergoing a transformation. Sectors such as renewable energy, clean energy, and low-carbon technologies are developing rapidly, providing new investment opportunities for investors.

3. Technological innovation: Technological innovation in the energy industry is an important driving force for the development of the industry. New extraction technologies, energy storage technologies, smart grid technologies, and more are emerging to improve the efficiency and sustainability of the energy industry.

4. Policy support: The support of governments in energy policy is essential for the development of the energy sector. The government's policy tilt in the fields of renewable energy, energy conservation and emission reduction provides a good development environment for relevant enterprises.

When investing in energy sector funds, investors also need to pay attention to the following aspects:

1. Risk management: The energy industry faces a variety of risks, including price fluctuations, policy changes, and technology risks. Investors need to establish a sound risk management system to deal with possible risks and challenges.

2. Industry cyclicality: The energy industry has obvious cyclical characteristics, and investors need to pay attention to the changes in the industry cycle in order to formulate a reasonable investment strategy.

3. Corporate fundamentals: When choosing an energy company for investment, investors need to pay attention to fundamental factors such as the company's financial status, profitability, and market share to assess the company's long-term development potential.

4. Environmental, Social and Governance (ESG) factors: In the energy sector, more and more investors are paying attention to ESG factors. These factors include the company's environmental protection measures, social responsibility and corporate governance structure, which are of great significance for evaluating the sustainable development ability and long-term investment value of the enterprise.

A brief overview of the definition and classification of the raw materials industry

1. Definition: The raw material industry refers to the industry that involves obtaining and preliminarily processing from nature to provide basic materials for other industrial fields. These raw materials are necessary for production and processing in other manufacturing sectors and are upstream in the supply chain.

2. Classification:

1. Classification by source of resources:

Mineral resources: such as metal ores, non-metallic minerals, fossil fuels, etc.

Agricultural resources: such as timber, cotton, rubber and other agricultural products.

Other natural resources: such as water, land, etc.

2. Classification according to the degree of processing:

Primary raw materials: raw materials obtained directly from nature without excessive processing, such as iron ore, crude oil, etc.

Semi-finished products or intermediate products: raw materials that have undergone preliminary processing but still need further processing, such as steel plates, plastic pellets, etc.

3. Classification by use or field:

Metal raw materials: such as steel, non-ferrous metals, etc.

Non-metallic raw materials: such as chemical raw materials, building materials, glass, etc.

Textile raw materials: such as cotton, wool, silk, linen and synthetic fibers.

4. Classification by production mode:

Extractive industries: industries that directly exploit natural resources, such as mining, logging, etc.

Raw material processing industry: the industry that carries out the preliminary processing of raw materials, such as oil refining, steelmaking, etc.

It is important to note that the above classifications are not strictly independent and sometimes overlap and overlap. The raw material industry involves many subdivisions and plays a vital role in the stability and development of the entire industrial system. At the same time, with the advancement of science and technology and the development of the industry, the classification of the raw material industry may also change.

What are the representative indices of the raw materials industry?

The representative indices of the raw materials industry mainly include the following:

1. SSE Material Index: This is an industry index published by the Shanghai Stock Exchange to reflect the overall performance of stocks in the raw materials industry of the Shanghai stock market. The index selects large-scale and liquid raw material industry stocks in the Shanghai stock market as sample stocks, providing investors with a tool to understand and invest in the raw materials industry.

2. CSI 300 Raw Materials Index: The CSI 300 industry index series divides 300 sample stocks into 10 industries according to industry classification standards, and compiles the index with all stocks in each industry as samples to form 10 CSI 300 industry indexes, reflecting the overall performance of stocks in different industries in the composition of the CSI 300 index and providing investors with analytical tools.

3. CSI All-Index Building Materials Index: refers to the market stock index published by CSI Index Co., Ltd. and based on the stocks of China's building materials industry. The index reflects the overall trend of the building materials industry.

The risk disclosure of promotional materials is as follows

The above views only represent the views of Wenxin Yiyan Model, which are for investors' reference only, and do not represent the views of the fund manager, do not constitute actual investment advice, and do not represent the fund's past and future holdings. Investment is risky and should be cautious. A publicly offered securities investment fund (hereinafter referred to as a "fund") is a long-term investment tool, and its main function is to diversify investments and reduce the individual risks brought about by investing in a single security. Unlike financial instruments such as bank savings that can provide fixed income expectations, when you buy fund products, you may not only share the income generated by the fund's investment according to your holdings, but also bear the losses caused by the fund's investment.

Before you make an investment decision, please carefully read the fund contract, fund prospectus and fund product key facts statement and other product legal documents and this risk disclosure, fully understand the risk-return characteristics and product characteristics of the fund, carefully consider the various risk factors existing in the fund, and fully consider your own risk tolerance according to your own investment objectives, investment period, investment experience, asset status and other factors, and make rational judgment and prudent investment decisions on the basis of understanding the product situation and sales suitability opinions. In accordance with relevant laws and regulations, the fund manager Penghua Fund Management Co., Ltd. and the relevant sales agencies of the fund make the following risk disclosures: 1. According to the different investment objects, the fund is divided into different types such as stock funds, mixed funds, bond funds, money market funds, funds of funds, commodity funds, etc., and you will get different income expectations for investing in different types of funds, and the greater the risks you will bear. 2. The fund may face various risks in the process of investment and operation, including market risks, as well as the fund's own management risks, technical risks and compliance risks. Huge redemption risk is a risk unique to open-end funds, that is, when the net redemption application of a single open-day fund exceeds a certain percentage of the total fund shares (10% for open-end funds, 20% for regular open-ended funds, except for special products specified by the China Securities Regulatory Commission), you may not be able to redeem all the fund shares applied for in a timely manner, or the payment of your redemption may be delayed. 3. You should fully understand the difference between regular fixed investment and lump sum deposit and withdrawal of funds. Regular investment is a simple and easy investment method to guide investors to make long-term investment and average investment costs, but it cannot avoid the inherent risks of fund investment, cannot guarantee investors to obtain returns, and is not an equivalent financial management method to replace savings. IV. Risk Disclosure of Special Types of Products:1.
