Core Viewpoint - The upcoming unlocking of shares for the first batch of companies listed on the Sci-Tech Innovation Board (STAR Market) is expected to have limited impact on the secondary market, as many major shareholders are voluntarily extending their lock-up periods or committing not to sell their shares immediately after the unlocking, reflecting confidence in the long-term value of their companies [1][2][4]. Group 1: Shareholder Actions - Nine companies have announced that their major shareholders will extend the lock-up period by 6 to 12 months or commit not to sell shares for six months post-unlocking, representing a market value of 808 billion yuan, which is over 40% of the total theoretical unlocking market value for the first batch of 25 companies [2][4]. - Major shareholders of companies like China Communication Signal and Rongbai Technology have voluntarily chosen not to unlock their shares, indicating strong confidence in their companies' future [2][3]. Group 2: Market Impact and Stability - The unlocking of shares does not equate to immediate selling, as different shareholders have varying intentions regarding exiting their positions, and any selling will be subject to strict regulations [4][5]. - The potential selling pressure from unlocking is mitigated by the fact that major shareholders and executives are limited in how much they can sell within a specified timeframe, which helps maintain market stability [3][4]. Group 3: Long-term Investment Value - The overall performance of companies on the STAR Market has shown strong growth, with a compound annual growth rate of 28% in revenue and 70% in net profit from 2019 to 2021, indicating robust long-term investment potential [6]. - The STAR Market is expected to attract long-term capital as liquidity improves post-unlocking, creating favorable conditions for institutional investors [6][7]. Group 4: Regulatory Environment - The STAR Market has implemented a unique inquiry transfer system for share reductions, which has proven effective in maintaining market stability and minimizing price fluctuations during share sales [5][6]. - Recent regulatory developments, such as the introduction of market-making trading rules, are anticipated to enhance liquidity and reduce market volatility, further supporting the STAR Market's growth and stability [7].
