In the A-share market, Lianxun Instruments (688808) has witnessed an astonishing cumulative surge of almost 190% within a mere 45 trading days. At one point, its stock price soared to an impressive 2,777.77 yuan, marking it as the sole stock to break through the 2,000-yuan threshold and overtaking Kweichow Moutai to claim the title of the new 'stock king.' This high-tech firm, which made its debut on the STAR Market at the end of April, focuses on electronic measurement instruments and semiconductor testing equipment. Its products find applications in diverse areas, including optical communication, silicon carbide power devices, and semiconductor integrated circuits. The substantial rise in its stock price is mainly driven by the explosive demand for AI computing power and the premium associated with domestic substitution. However, it is also swayed by market sentiment and valuation bubbles. The company intends to utilize the funds raised from its IPO to invest in projects like next-generation optical communication testing equipment, automotive-grade chip testing equipment, and memory testing equipment, aiming to strengthen its foothold in the market.
