For listed companies to experience a consistent and significant upward trajectory in their stock prices, they generally must fulfill several key criteria. These include having a relatively low market capitalization, a modest share capital, a reasonable level of trading volume, robust potential for earnings growth, and alignment with trending investment themes. Drawing on these standards, the author has pinpointed 17 small-cap, relatively low-activity hard-tech stocks that exhibit high growth potential. The selection criteria are as follows: as of June 18, the A-share market capitalization must not surpass RMB 15 billion, and the circulating A-share capital should be less than 500 million shares. Additionally, these stocks should have demonstrated an average daily turnover rate of 1%-3% over the past month (spanning from May 19 to June 18, 2026). Furthermore, they are expected to turn a profit in 2025, with institutional forecasts projecting net profit growth exceeding 40% for both 2026 and 2027.
