In early trading today, A shares rose slightly, and the Shanghai Composite Index, Shanghai and Shenzhen 300 and Shanghai 50 all set new highs for the year again, and the turnover between the two markets obviously showed an enlarged trend.

On the disk, the glass substrate, pork, gold, tourism and other plates led the increase, while household goods, real estate, PEEK materials, construction machinery and other plates led the decline.

Pork prices continue to strengthen

In the morning, the pork concept was strong across the board, and the stock index opened high, rising nearly 4% in intraday trading, with half-day trading ahead of one-day trading.

Zhenghong Technology pulled up vertically after opening and closed the trading limit in only about 1 minute; * ST Aonong opened by the daily limit, rising 4 degrees in nearly 6 trading days; Tianyu Ecology (603717), New Hope (000876) and New Wufeng (600975) were among the top gainers.

Issued according to the Ministry of Agriculture and villagesPennslammer35000The "implementation Plan for the Regulation and Control of Pig production capacity (revised in 2024)", with reference to the production data of the national pork production of 55 million tons in normal years, sets the regulation and control target for the stock of breeding sows, that is, the normal number of breeding sows is stable at about 39 million.

According to the latest data from the Ministry of Agriculture and villages, by the end of the first quarter of 2024, there were 39.92 million breeding sows in the country, a decrease of 3.14 million, or 7 percent, compared with the same period last year.Pennslammer35000.3%; a decrease of 1.5 million heads, or 3.6%, compared with the previous month. The goal of regulating and controlling the stock of breeding sows is basically achieved, and the production capacity of breeding sows is nearing the end.

The decline in the stock of fertile sows has also led to a continuous decrease in the number of pig stocks. According to the Bureau of Statistics, China kept 408.5 million live pigs in the first quarter, down 5.2 percent from the same period last year, and 194.55 million pigs, down 2.23 percent from the same period last year.

The reduction in supply has led to a continuous rise in pork prices. since February, the main contract for pig futures has risen from a low of 15710 yuan / ton to today's highest 18470 yuan / ton, up nearly 18%.

Data from China Pig raising Network also show that recently, three yuan pig prices at home and abroad have risen sharply. Among the 31 provinces / municipalities / autonomous regions that can be monitored, the trend of pig prices has risen by 27, flat by 4 and falling by 0. Only Anhui Province, Fujian Province, Gansu Province, Xizang Autonomous region and other four regions showed a flat trend, while other regions have increased to varying degrees. In the north and south regions of the country, pig prices rose across the board, the increase in pig prices in the north expanded significantly, and the markets in the southwest and South China were mainly weak, stable and strong, and the market showed a rising trend beyond expectations.

Recently, a number of listed companies have publicly indicated that since the beginning of this year, the loss of pig farming business has been significantly reduced, and it has made a profit in some time. Ruxin Hope said a few days ago that in April, the company made an overall monthly profit at the level of about 15.1 yuan / kg of pig price. All kinds of costs of raising pigs are also rapidly reducing, from the current operating results and cost decline, the previous active adjustment is very effective. The probability of the performance continuing to rise in May and June is also relatively high.

Huatai Securities pointed out that the continued losses in the pig farming industry since 2023 and the continuous decline in the stock of breeding sows may lead to a quarterly relief of pig supply pressure in 2024. According to historical experience, in the pig cycle reversal market, the rising price on the right side of the pig price leads to higher flexibility in the rising stage, among which the pig enterprises with excellent cost and high exchange rate may also walk out of another wave of stock price rise driven by performance cash. it is suggested that the active layout of pig farming plate.

AI promotes the rapid development of glass substrates

A-share came out with a new concept, the glass substrate strengthened sharply in early trading, and the plate index once rose nearly 6%.

After Lehman Photoelectricity continued its 20% limit last Friday, today's high opening and walking once again touched the limit; Vogel Optoelectronics (603773) rose by the limit for the second day in a row; three super new materials (300554), Jinlong Mechatronics (300032), Pentagon Optoelectronics and other top gains.

The heat of AI hardware is gradually extended from computer chip to optical module and copper connection, and the field of packaging materials will also usher in new changes. As a new type of packaging substrate material, glass substrate has important applications in the field of semiconductor packaging.

In order to achieve the major technological breakthrough of increasing transistor density to achieve more efficient computing power, Intel plans to mass-produce glass substrates for the next generation of advanced packaging between 2026 and 2030, bringing more transistors into a single package. and continue to promote Moore's Law.

Intel believes that glass substrates will allow them to place 50 per cent more bare wafers on the chip, thus stuffing more Chiplet into a very large system-level package that holds multiple silicon. In addition, the glass substrate also helps to improve the focal depth of lithography and ensure the precision and accuracy of semiconductor manufacturing.

According to Prismark statistics, the global IC packaging substrate industry is expected to reach US $21.4 billion in 2026, while with the entry of Intel and other manufacturers, the replacement of glass substrates for silicon substrates will be accelerated, and the permeability of glass substrates is expected to reach 30% within 3 years.

Recently, listed companies have revealed the layout of the glass substrate industry chain on the interactive platform. Vogg Optoelectronics has said that from the perspective of product and technology application prospects, based on the company's glass fund attribution and copper through-hole technology (TGV technology) and glass substrate circuit design and development capabilities, the company's glass substrate can be used in the vertical packaging carrier interposer of CPO 2.5D/3D packaging and the packaging substrate below to realize the interconnection between optical modules and chips, and the company is also paying continuous attention to this field.

Lehman Optoelectronics, Dazhou CNC, Longli Technology (300752) and Dier Laser (300776) have also disclosed their technical reserves and industrial layout in glass substrates.

Oriental Fortune Securities believes that the evolution of packaging methods is driven by the demand for high computing power, and the market scale of advanced packaging technologies such as 2.5D/3D and Chiplet is gradually expanding. Compared with organic substrates, glass substrates can significantly improve electrical and mechanical properties and meet the needs of larger packaging, which is an important direction of the development of advanced packaging in the future.
