In April, senior executives collectively reduced their holdings： Geely responded to the ＂option expiration exercise＂

　　Introduction: Since April, many senior officials, including President of Geely Holding Group, CEO of Geely Automobile Group and President An Conghui, have intensively reduced their holdings of Geely shares.

　　In April, Geely Automobile (HKEx: 00175) ushered in intensive reduction of senior management. The reporter learned from Geely that the response is: collective exercise of options when they expire.

　　According to the equity data of the Hong Kong Stock Exchange, since April, many senior officials including President of Geely Holding Group, CEO of Geely Automobile Group and President An Conghui have intensively reduced their holdings of Geely shares.

　　On April 16th, Zhejiang Geely Holding, whose actual controlling shareholder is Li Shufu, chairman of Geely Holding Group, reduced its holding of 85.22 million shares of Geely Automobile. An Conghui reduced his holdings by 10.7 million shares at a price of HK$ 16.53 each, with a total value of about HK$ 177 million.

　　On April 17th, An Conghui once again reduced his holdings of 5.472 million shares of Geely Automobile at a price of HK$ 17.5. After this reduction, An Conghui only holds 102,000 shares of Geely Automobile, accounting for 0% of the issued voting shares. On the same day, Yang Jian, Li Donghui and Gui Shengyue, executive directors of Geely Automobile, also reduced their holdings of Geely Automobile. Among them, Yang Jian holds 8.475 million shares, Li Donghui holds 1.376 million shares and Gui Shengyue holds 3 million shares. After the completion of this reduction, the percentages of the three people in the issued voting shares are 0.07%, 0.02% and 0.12% respectively.

　　On April 23rd, Geely Automobile was once again collectively reduced by two executive directors. Among them, Gui Shengyue reduced his holdings by 800,000 shares at an average price of HK$ 17.8, and Hong Shaolun reduced his holdings by 270,000 shares at the same average price. After the completion of this reduction, the percentage of the issued voting shares of the two is 0.12% and 0.04% respectively.

　　Market analysts believe that the intensive reduction of executives has dragged down the share price of Geely Automobile. Geely Automobile hit an eight-month high of HK$ 19.14 on April 18, and then closed down continuously for several trading days, and closed at HK$ 16.02 on April 26. According to Grunhui APP, since April, funds from Southbound have continuously flowed out of the stock, and the accumulated net selling amount has reached HK$ 3.015 billion.

　　Geely told reporters that the above reduction was due to the expiration of some executive options about 10 years ago, which had nothing to do with actual operation.

　　In fact, it is irrational to attribute the stock price decline entirely to the reduction of senior officials. In fact, on April 12th, six Geely Automobile executives, including An Conghui, Gui Shengyue, Yang Jian and Li Donghui, successively reduced their holdings of 54 million Geely Automobile shares. Li Shufu and Geely Holding Group respectively increased their holdings of 55.03 million shares of Geely Automobile.

　　For the future trend of Geely Automobile’s share price. Institutions have different views. Morgan Stanley is an active bear. It once published a technical opinion report, which reduced Geely Automobile’s investment rating and target price by HK$ 8. The bank believes that Geely’s share price will fall in the next 30 days, and the probability of this happening is expected to be between 70 and 80%. The reason behind this is that the inventory level of Geely Automobile continues to rise. It is estimated that the company’s wholesale sales in April will drop by 8-10% year-on-year, and retail sales will drop by 12-15% year-on-year. According to the bank, the inventory of Geely’s Lexus brand has risen to the level of more than two months.

　　In a recent research report, Nomura Securities still maintained Geely Automobile’s "Buy" rating and raised the company’s earnings per share forecast for 2019-2020 by 1%. Daiwa also expressed the view that it is still optimistic about Geely Automobile (00175) and gave it a "buy" rating, believing that it is a good time to absorb it. The target price for Geely Automobile is maintained at HK$ 22. (Yang Haiyan)

　　Peak forest hiking

　　Autumn Tour: Yingde

　　Autumn is the best season for outdoor sports. Qingyuan Yingxi Peak Forest is located in Jiulong, Huanghua (formerly called Mingjing Town) and Yanbei, 60 kilometers southwest of yingde city. It is a valley surrounded by mountains, with karst landform and natural landscape like Guilin, so it is called "Yingxi Small Guilin", also known as "Yingxi Peak Forest". There are thousands of limestone peaks densely distributed here, with streams, caves and ancient buildings dotted among them, and it has the reputation of "the first peak forest in the south of the country".

　　In Yingxi Peak Forest, you can choose to walk around the countryside. The starting point of the general line is Shuiping Village — Niudong — Zhaibei Primary School-Xiayan Village-Hujigang (Crossing the Bridge) — Jiulong town — Central primary school — Unity Primary School — Pengjiaci — Huanghua town, you can choose camping here. And from huanghua town (Mingjing) — Zhaozhou Ancient Bridge — Yongfeng Ancient Temple — Guanyin Valley — Gold Rushing in Qianzuxi — Along the back town, each section is about 10 kilometers. There are many delicious foods along the way, and there are many camps to experience camping.

　　Bei Jiang qi hang pin seafood

　　Autumn tour: Sanshui

　　Located in Sanshui, Foshan, the main dike of Beijiang levee is more than 60 kilometers long, with two main riding greenways, which are full of greenery and beautiful scenery, connecting country parks, waterfront parks and historical and cultural sites. If you go in the afternoon, it coincides with the sunset, and you can still see the river is deep red and picturesque. This place, which is only an hour’s drive from downtown Guangzhou, is a good place for leisure travel in the golden autumn weekend. Visitors can ride on the greenway and fly kites on the riverbank.

　　On the Beijiang levee, there are many seafood restaurants, where visitors can taste authentic bream and shrimp. In addition, you can also try the local smelly fart vinegar hot pot. Diners can order chicken, ribs, sweet potatoes and other ingredients and cook them in the smelly fart vinegar, just like the hot pot. After the stinky fart vinegar is boiled, take a bite. Unexpectedly, the vinegar is not smelly, just like the taste of home-cooked old fire soup. The salty taste is a little sour, and the subtle thick feeling adds to the taste of rice vinegar. In addition, the crab in chicken soup is one of the specialties of Sanshui. The restaurants most recommended by local people are "Banjiangqiao Seafood Shop" and Lujiang Fishing Village.

Another foreign-funded institution has voiced its voice! China stock is the most valuable in the world.

China Fund News reporter Yao Bo

The rebound of Hong Kong stocks stopped. On January 26th, the Hang Seng Index closed down 1.6% and the Hang Seng Technology Index fell 3.75%. Among them, pharmaceutical and technology stocks led the decline, and Yaoming fell sharply due to the news, with the largest decline among the HSI constituent stocks; Lenovo Group also fell by nearly 10%, the largest drop among the constituents of the Hang Seng Technology Index.

Previously, the relatively stable southbound funds began to buy in large quantities, indicating that the confidence of mainland funds has gradually recovered. On January 26th, southbound funds bought a net amount of HK$ 5.323 billion, which was the day that they bought the most after this round of Hong Kong stock market crash on January 17th.

Some foreign-funded institutions have spoken out, saying that China stocks are the most valuable assets in the world, and even willing to leverage to buy high-quality China stocks.

Yao Ming system plummeted.

In the afternoon, Yaoming suddenly fell sharply, with WuXi PharmaTech falling by 32% at most, YaoMing Bio falling by 28% at most, and YaoMing United of the same line falling by 24% at most.

It is worth noting that Yaoming Bio triggered the market fluctuation adjustment mechanism at 2: 7 pm and 2: 14 pm, which is a measure aimed at alleviating excessive market fluctuation, and usually starts when the stock price fluctuates greatly in a short time. The launch of this mechanism led to a five-minute cooling-off period for stock trading, with a view to stabilizing market sentiment.

It is understood that the adjustment mechanism of the Hong Kong stock market aims to alleviate the extreme price fluctuations caused by automated trading. When the relevant stock price exceeds 10% (constituents of Hang Seng Composite Large-cap Index), 15% (constituents of Hang Seng Composite Medium-cap Index) or 20% (constituents of Hang Seng Composite Small-cap Index) of the last trading price five minutes ago, the market adjustment mechanism will be triggered and a five-minute cooling-off period will begin immediately.

At the close, WuXi PharmaTech fell by 16%, WuXi Bio by 18% and WuXi PharmaTech by 20%.

According to the latest information of the Hong Kong Stock Exchange, on January 19th, BlackRock reduced its holdings of 1,116,927 H shares of Wuxi PharmaTech at a price of HK$ 783,646 each, with a total amount of about HK$ 87,527,500. After the reduction, the latest shareholding number is about 26.7607 million shares, and the latest shareholding ratio is 6.91%.

The representative work of Gü len Management, CEIBS Healthcare, also reduced its holdings of WuXi PharmaTech A shares. In the third quarter of 2023, CEIBS Healthcare held 61.5 million shares of Wuxi PharmaTech, and in the fourth quarter of 2023, it held 58.59 million shares, a decrease of 2.9 million shares.

According to the latest information of the Hong Kong Stock Exchange, Chairman Li Ge increased his holding of 5,235,500 shares of Yaoming Bio on January 24th at a price of HK$ 287,123, with a total transaction amount of about HK$ 150 million. After this increase, Li Ge’s latest shareholding in Yaoming Bio is about 589 million shares, accounting for 13.84% of the company’s total share capital.

Foreign capital sees more China assets.

After the correction of Hong Kong stocks, favorable policies have been frequent, and foreign investors have been high-profile bullish on China stocks. A co-founder of Gavekal Group wrote that China stock market is now the most valuable market in the world.

Charles Geff, the co-founder of the company, pointed out in an article on January 24th that the value of China stock was undervalued relative to cash, China bonds, gold and other stock markets in the world, and now it is the most valuable investment in the world. Moreover, China is at the stage where the profit growth of enterprises begins to exceed the cost of capital, which means that profits will increase substantially, enterprises will resume investment and recruitment, and China enterprises will see a booming profit. He said that he even wants to use leverage to buy high-quality China stocks.

It is understood that Gavekal Research, headquartered in Hong Kong, provides asset allocation consulting services and manages some global funds.

In addition, some fund managers at VanEck pointed out that the China stock market is at an inflection point, which may now constitute a buying opportunity this year.

If you don’t understand these principles of scientific movement, no amount of exercise will be in vain.

I know that exercise is very important for health, but every exercise can’t last long. Am I not suitable for exercise at all?

Scientific exercise can not only effectively improve cardiopulmonary function, promote human metabolism, but also promote people’s physical and mental health. Combining with your own situation and following the principle of scientific movement, you can definitely do it ~

How can I find a sport that suits me?

Before you plan to exercise, for your safety, you can do the following physical activity preparation questionnaire first.

Physical activity preparation questionnaire

one

Did the doctor tell you that you have a heart disease or can only take part in physical activities recommended by the doctor?

When you do physical activities or exercise, have you ever felt chest pain or severe breathlessness?

three

Since last month, have you ever felt chest pain or severe breathlessness when you didn’t take part in physical activity or exercise?

four

In the past 6 months, when you were doing physical activities or sports, did you ever fall down or lose consciousness because of dizziness?

five

Do you have any bone or joint pain or dysfunction aggravated by physical activity or exercise?

six

Did the doctor tell you that your blood pressure is over 180／110mmHg?

Note: This questionnaire was established by the research group of Professor Wang Zhengzhen of Beijing Sport University with reference to relevant information. It is suitable for people aged 15-69, and people over 69 should consult their doctors before doing fitness activities.

Tips

If you answer "Yes" to any of the above questions,

Please stop taking part in this fitness exercise and pay attention to:

(1) Consult a doctor before taking part in the fitness program, and explain which question in the questionnaire is answered as "Yes";

(2) Take part in fitness activities step by step, gradually adapt, the intensity of exercise should not be too large, and the time should not be too long;

(3) You can restart the fitness mode that has been proved to be safe;

(4) You can also participate in activities recommended by doctors or activities allowed by doctors;

(5) timely use of necessary medication.

If you answer "No" to all the above questions,

You can continue to do fitness exercises,

But please note:

(1) Take part in a large amount of exercise or exercise intensity exercise step by step to avoid excessive fatigue;

(2) Take part in further health evaluation, and make the best fitness plan accordingly.

In recent years, with the in-depth implementation of national fitness, people’s participation has been continuously improved, and "more exercise and less illness" has increasingly become a social consensus. What are the important principles of the scientific movement? How to avoid sports risks? Look down ~

Late-night exercise is extreme

In fact, when to exercise has little influence on the fitness effect. From the factors that affect the fitness effect, the key is that the exercise load should match the physical health of the individual.

However, sweating exercise in the middle of the night when you should be sleeping may be a reduction in your health. Because it may disturb the biological rhythm.

For office workers, it is more appropriate to squeeze out 30 minutes to 1 hour for exercise before dinner after work. If you occasionally work late under special circumstances, such as getting off work at 10 o’clock in the evening, and you really want to exercise, it is recommended to take a light activity for 30 minutes and sweat.

Exercise is systematic and long-term. If you don’t exercise one day, you can continue to exercise later. It is not necessary or encouraged to exercise late at night.

Choose a sports environment according to the weather

Don’t exercise in cold, hot, high humidity, strong wind, polluted and radioactive environment;

The temperature difference between spring and autumn is large, and the temperature is low in the morning and evening. Pay attention to the influence of temperature and wind when exercising;

Exercise in summer should guard against heatstroke;

If there are special circumstances such as smog and sudden drop in temperature in winter, it is not recommended to do outdoor sports.

Basic principles of scientific movement

Safety principle

It is very important to do warm-up activities before exercise and stretching exercises after exercise, but the latter is often ignored by many people. During exercise, human muscles constantly contract and exert their strength, and their elasticity decreases. If they don’t stretch for a long time after exercise, these problems may be brought about: local inflammatory factors and metabolic wastes can’t be discharged, which leads to increased fatigue and slow recovery; The next training with fatigue will increase the risk of injury and induce sports injuries such as "running knee".

Studies have confirmed that stretching after exercise helps to relax muscles and improve muscle elasticity, which is one of the "magic weapons" to reduce sports injuries. Stretching practice time should be at least 10 minutes, or about 1/3 of the duration of exercise.

Principle of comprehensiveness

Different types of exercise will bring different fitness effects, and the exercise style is better, including aerobic exercise, strength training and flexibility training.

Aerobic exercise can make people’s heart and lung function better, and it also directly affects the activity ability of the whole body organs;

Strength training helps to improve muscle strength and avoid problems in daily activities such as walking, running and jumping caused by insufficient strength;

Flexibility training is stretching exercise, which can improve the stretching ability of muscles and effectively prevent sports injuries.

Accuracy principle

As long as the fitness action standard and exercise load are reasonable, sports injuries can basically be avoided. The "fake" action of posing, not exerting force and nonstandard "wrong" action are the main causes of sports injury accidents.

For example, "sit-ups with your head in your arms" is a typical nonstandard movement, which may lead to sports injuries. If your hands are lightly placed behind your head or on your ears or chest, you should mainly use your abdomen to pull your trunk, instead of using your hands and head, which is not harmful, but also can exercise your core muscles well.

Principle of gradual progress

The frequency of exercise varies from person to person. Generally speaking, you should exercise at least three times a week, and it is best to gradually increase it to five times a week to ensure the fitness effect.

No matter what your physical fitness level is, you should do what you can when exercising, and you can’t ignore the signals sent by your body.

If you have dizziness, dizziness, chest pain, nausea, shortness of breath, palpitation, vomiting and other symptoms during exercise, you should stop exercising immediately and seek medical advice in time. If you have persistent and obvious fatigue after exercise, you should appropriately reduce the exercise time or times. When you feel in good physical condition, you can also exercise for a while.

Perseverance principle

To achieve good fitness results, it is essential to participate in sports persistently.

It is suggested that according to one’s physical health and sports ability, an achievable exercise goal should be established and a feasible exercise plan should be made. Work and rest should be combined in life to avoid giving up the exercise plan because of being too busy or too tired; We should understand sports from the height of "exercise is a part of life" and stick to it for a long time.

The first gene platform of polymer materials in China was born, which is called ＂ChatGPT of polymer version＂.

The key bottleneck restricting the development of advanced equipment is to meet the requirements of advanced resin composite materials with high strength, high temperature resistance and light weight. At present, such a difficult problem is expected to be solved. The reporter learned from East China University of Science and Technology that the first domestic polymer material genome research and development platform (AI plus polymer software platform) developed by Professor Lin Jiaping’s team was recently released in Shanghai.

The software is called "polymer version of ChatGPT", which contains the first database of resin structure and properties and chemical reaction between groups in China. Users only need to input the resin structure, they can quickly obtain its mechanical, thermal and dielectric properties, and can also make performance prediction and high-throughput screening through this software, so as to develop high-performance polymers and their composites with faster efficiency and lower cost.

"The research and development of new materials has entered the era of intelligent manufacturing from the era of trial and error of scientists." Lin Jiaping introduced that in the past, it often took 2-3 years or even longer for a new material to go from design, experiment to productization. Now, relying on this "polymer virtual laboratory", R&D personnel can find the optimal solution of structural design and formula optimization only through 2-3 iterations, and the experimental time is greatly reduced. The team will join hands with the industry to promote the development of AI plus polymer research paradigm to the whole industry chain.

Powerful database and forecasting system lead the industry.

What are the highlights of the AI plus polymer software platform? Lin Jiaping introduced that as an important achievement in the cross field of AI and digital technology and polymer materials, a powerful database is an important support of the platform and can be described as the cornerstone of material genetic engineering. The first database of resin structure and properties and chemical reaction between groups established by the team in China contains nearly 150,000 performance data of more than 34,000 polymers and nearly 1.4 million chemical reaction data of 58,516 basic reaction templates.

It is worth mentioning that these data mainly rely on dozens of graduate students and undergraduates in the past three years, especially during the epidemic, to standardize, enter and store them one by one. Based on the database, the team created a machine learning prediction model for more than ten properties of polymers, and built a research and development platform for polymer materials genome, which has multiple functions such as data retrieval, performance prediction and formula optimization.

The reporter saw in the team’s live demonstration that when users use the AI plus polymer software platform to predict the performance of polymer materials, they only need to click "Draw Structure" first, input the drawn strings of epoxy resin and curing agent into the corresponding input boxes, and then click "Start Prediction". After a few seconds, the page will return to the performance prediction data of epoxy resin calculated in the background.

So, how does this software compare with foreign counterparts? For example, Gao Liang, one of the team members and a special researcher at East China University of Science and Technology, has similar software in the United States and Japan. However, in terms of database richness, prediction accuracy and functional diversity, AI plus polymer software platform is superior. "Our goal is to seize the opportunity of digital and artificial intelligence to change the new material industry, develop high-performance polymers and their composites with faster efficiency and lower cost, and realize the original innovation and intelligent manufacturing of polymer materials." Gao Liang said.

The research and development of new materials has entered the era of "intelligent manufacturing" from the era of experience "trial and error"

The development of AI plus polymer software platform can be described as a sword after ten years. It is reported that since 2011, Lin Jiaping’s team has seized the frontier field of material research-material genetic engineering to start related work.

With the cooperation of gene combination screening and AI tools, the team developed a series of advanced composite matrix resins. For example, the curing temperature is less than 300℃, the 5% thermal decomposition temperature is more than 650℃, and the glass transition temperature is more than 600℃. For another example, a new type of high-temperature resistant and high-toughness poly (alkynyl imide) resin is superior to polyimide in processability, heat resistance and interface properties, and its mechanical properties are equivalent to polyimide. Related new resins have been evaluated by many aerospace institutes for the performance of composite materials and components.

"The AI plus polymer software platform is like a polymer virtual laboratory. The virtual design of the platform and the method of high-throughput prediction will greatly improve the research and development efficiency." Lin Jiaping introduced that at present, the platform has been tried in more than ten enterprises such as Shanghai Huayi Group Resin Factory, Shanghai Aerospace Eighth Institute, Jinfei Carbon Fiber Technology and Jinshan Petrochemical Institute, and will be used to the public.

It has gained obvious competitive advantage in serving ultra-large-scale data center users and innovative businesses such as public cloud and artificial intelligence. Now, the number of hyperscale data centers is increasing almost linearly, and it has exceeded 800 in the second quarter. In addition to building new hyperscale data centers, hyperscale operators are also increasing the capacity of existing facilities, and these factors continue to stimulate the growth of server shipments.

At the same time, with the development of ultra-large scale data centers and the transformation of traditional enterprises, the adjustment of market structure will be further deepened. For ultra-large scale data centers, innovative technologies and energy-saving schemes such as multi-node servers, artificial intelligence servers, edge servers, liquid cooling, natural air cooling, etc. will grow faster. Server manufacturers need to pay more attention to the innovative needs of ultra-large scale customers. At the same time, enterprise users will develop more innovative businesses, and the migration from traditional infrastructure to emerging infrastructure will be accelerated, thus promoting market capacity.

Professionals predict that the server market will usher in an explosive growth trend in the next five years. It is estimated that the global server market will reach USD 155.67 billion in 2026, and the five-year compound growth rate will be 8.3% by 2026. In order to meet the new challenges and consolidate the effectiveness of servers in an all-round way, Inspur Information will continue to increase R&D investment, build a more perfect server product line, and meet the new demands of digital transformation in various industries.
