[Brokerage research becomes more popular in November, favoring electronics, mechanical equipment and other industries] On November 12, the Securities Research Institute ushered in a busy period of research. Data shows that since November, securities firms have surveyed a total of 328 listed companies, with the survey targets focusing on industries such as electronics, machinery and equipment, and medicine and biology. During the same period, brokerages adjusted the ratings of 18 listed companies, and the number was close to the level for the entire month of October.
