Core Viewpoint - The recent share reduction by Guo Fengming, the controlling shareholder of Kanda, raises concerns about the company's long-term value despite the stock price resilience and positive earnings growth [1][3][4]. Group 1: Share Reduction Details - Guo Fengming's share reduction plan, which was first disclosed on February 17, 2025, involved a maximum reduction of 3% of shares, with a total of 512.26 million shares sold, amounting to approximately 57.39 million yuan [2]. - Since March 2023, Guo has cumulatively reduced 15.33 million shares, cashing out over 203 million yuan, decreasing his holding from 51.92% to 45% while still maintaining control [3]. Group 2: Market Reaction and Institutional Involvement - During the share reduction period, Kanda's stock price increased, reaching a high of 12.24 yuan, contrasting with the slight rise of the Shanghai Composite Index [2]. - Institutional investors showed a net buying of 34.14 million yuan on the same day as the reduction, indicating a complex market dynamic of shareholder selling and institutional buying [2]. Group 3: Financial Performance and Operational Concerns - Kanda reported a revenue of 81.26 million yuan in Q1 2025, a year-on-year increase of 17%, with a net profit of 31.98 million yuan, up 20.88%, and a maintained gross margin of 44% [4]. - However, operational efficiency is a concern, with accounts receivable turnover at only 0.19 times and inventory turnover at 0.21 times, indicating low operational efficiency [4]. Group 4: Investor Insights and Strategic Considerations - The situation illustrates the coexistence of shareholder reduction and institutional buying, suggesting that the impact of single signals in the market is diminishing [5]. - Investors should monitor the implementation of policies such as the "Lightweight Development Plan for Rail Transit Equipment" expected at the end of June, which may influence the sector [5]. - The reduction in shareholder numbers, currently at 17,100, down 12% from peak levels, indicates increased concentration of shares, which may heighten stock price volatility [5].
