真惨，新股上市就跌去三分之一，一中签股民3万利润变3万亏损

Core Viewpoint - The rapid fluctuations in stock prices of newly listed companies in the A-share market have led to significant losses for investors, with over 70% of new stock investors experiencing losses on the first trading day [1][3][4]. Group 1: Market Dynamics - The absence of price limits on the first trading day has turned new stock listings into a speculative playground, with some stocks seeing first-day gains exceeding 500% and extreme cases reaching 19 times the initial price [3][4]. - High turnover rates are indicative of market bubbles, with one new stock experiencing a turnover rate of 91.68%, suggesting that nearly all circulating shares were traded [3][4]. - Following initial surges, it has become common for stocks to open lower the next day, with one automotive stock dropping 13.15% on the second day and 33.35% from its peak by the third day [4]. Group 2: Investor Behavior - A significant portion of new stock purchases is made by retail investors, with 99.7% of accounts buying into temporarily suspended stocks, leading to a 94.7% loss rate among these investors [6][8]. - The phenomenon of "floating profit addition" has been identified as a trap, where investors mistakenly believe that high intraday prices will serve as support levels, ignoring valuation risks [7][10]. - Despite the high risk of losses, enthusiasm for new stock investments remains strong, with over 14 million accounts participating in new stock subscriptions in 2025, reflecting a cognitive bias towards the belief that new stocks are always profitable [8][10]. Group 3: Institutional Strategies - Public funds generally adopt a strategy of selling on the first day of trading, unless the fundamentals are exceptionally strong and valuations are reasonable [10]. - Key warning signals for investors include a turnover rate exceeding 80% on the first day and a price-to-earnings ratio significantly above the industry average, which can indicate a high likelihood of subsequent price declines [10].
