What happened? After the boss shouted, the bibcock of hundreds of billions of chips went up and down again and again.

Today, A-share semiconductor leader Weir shares closed trading limit in early trading, the market capitalization returned to 250 billion.

It is worth noting that yesterday and the day before yesterday, the other two chips with a market value of hundreds of billions of dollars, Ziguang Guowei and Zhaoyi Innovation also rose by the daily limit, and investors frequently asked: what's the situation?

The northward capital of 1.2 billion yuan scrambled to raise Ziguang Guowei.

From the perspective of funds, among the Daniel stocks that have risen repeatedly this week, Ziguang Guowei was on the list of dragons and tigers with an increase on November 30. data show that northward funds totaled 660 million to raise Ziguang Guowei on the same day, buying two seats. The top hot money player, a new commonly used seat, King Nanjing Taiping South Road, appeared, with a net purchase of 93.46 million.

Northbound funds bought a total of 1.26 billion yuan in Ziguang Weiwei in the first three trading days of this week, ranking first among net purchases of shares. Zhaoyi Innovation and Weir shares were also increased by 376 million and 184 million of northbound funds this week, respectively.

At the same time, the net inflow of main funds this week into Zhaoyi Innovation and Ziguang has also exceeded 200 million.

Automotive semiconductors "greater demand in the second half"

What the above chips have in common is to dig deep into the manufacture of automotive chips. Since the second half of 2020, the supply of automotive chips has been tight, and the application of domestic chips has increased. Last week, Wang Chuanfu, chairman and president of BYD Group, ignited a new round of attention in the market: "in the semiconductor field, the demand for semiconductors by electric vehicles is 5-10 times higher than that of traditional cars. However, because of the "lack of core", about 7 million of the world's electric cars are not produced. Electric cars are the first half, smart cars are the second half, and smart cars have a greater demand for semiconductors. "

The supply and demand of automotive chips has always been in a tight balance, due to the relatively low gross profit margin, stringent process requirements, the use of mature process capacity growth is limited, capacity has been relatively tight.

At present, the "lack of core" of automotive specification-grade semiconductors has been initially alleviated. Inventories of major automotive chip suppliers on the market increased for the first time in nearly nine months, it was reported yesterday. Total inventories at Renesas, NXP, Infineon, St and Texas Instruments rose 0.7% year-on-year at the end of September, the first year-on-year increase in nearly three quarters.

Citic Construction Investment Securities also said that although the current demand for semiconductors has a certain structural differentiation, it is still in a state of high bearing and tight supply and demand as a whole, and there is no sign of easing or loosening of production capacity this year. Overall production capacity is expected to remain tight and prices continue to rise in 2022.

In 2021, A shares ushered in Fuhan Micro and other automotive semiconductor plate "new blood", domestic automotive chip leader Ziguang Guowei, Weir shares, Zhaoyi Innovation, Starr Semiconductor, Quanzhi Technology, Siwei Tuxin and other companies are also actively expanding production to cope with the "lack of core tide". As of the third quarterly report, the performance of the following related enterprises increased by more than 100% year-on-year (including all business income).

Societe Generale Securities predicts that in the future, in addition to the total growth of the market, the current situation of foreign manufacturers taking the lead in car specification-level chips will be changed.
