According to PANews, the Shanghai Stock Exchange has officially released new trading rules, including the 'Guidelines for the Self-Regulation of Listed Companies on the Sci-Tech Innovation Board No. 5 – Sci-Tech Growth Layer.' These guidelines emphasize the importance of managing investor suitability. Recent reforms have not introduced new investment thresholds for individual investors participating in the trading of stocks on the Sci-Tech Growth Layer. Existing requirements remain at a financial threshold of 500,000 yuan in assets and two years of investment experience. Furthermore, in accordance with the 'Opinions on the Sci-Tech Innovation Board,' investors must sign a specialized risk disclosure statement before investing in newly registered and unprofitable technology companies on the Sci-Tech Growth Layer.
