Analysis of Abnormal Price Fluctuations and Impact of Suspension for Verification of Haixia Innovation (300300.SZ)

The popularity of 300170.SZ (Hand Information) stems from improved fundamentals and business expansion: in the first three quarters of 2025, net profit increased by 15% year-on-year, AI business revenue exceeded 100 million yuan (annual target of 300 million yuan), and it launched a Hong Kong H-share IPO plan to enhance its internationalization level [0][1][2]. Its improved gross profit margin and cash flow indicate enhanced business quality [0].
300300.SZ (Haixia Innovation) exhibits speculative characteristics: its stock price rose by 185.89% from October 27 to November 17, hit the daily limit on November 17 (closing price 18.24 yuan, turnover rate 27.21%), then was suspended for verification on November 18 [0][3][4][5][6]. The company’s valuation is far higher than the industry average (555.31x rolling PE, 12.06x PB), but its operating revenue only increased by 4.75% in the first three quarters of 2025, with a net loss of 17.2383 million yuan [0].

There are fundamental differences in the driving factors behind the popularity of the two: Hand Information is supported by performance growth, AI layout, and capital operations, while Haixia Innovation’s rise lacks fundamental support and is a short-term speculative trend. Haixia Innovation’s valuation is seriously disconnected from its operating data, so investors should be vigilant against the risk of a correction [0].

: Haixia Innovation faces risks such as the bursting of valuation bubbles and uncertainty about the results of the suspension verification; Hand Information needs to pay attention to the achievement of AI business targets and the progress of H-share listing [0][3][6].
: Hand Information’s AI business and international layout may bring long-term growth; if there are no major negative news after Haixia Innovation’s verification, there may be short-term trading opportunities, but caution is needed [0][1].

Hand Information has fundamental support and is suitable for long-term attention; Haixia Innovation has an excessive short-term increase and overvaluation, so investors need to remain cautious and avoid blind chasing of high prices. During the suspension verification period, it is recommended to pay attention to company announcements and industry trends [0][3][5].
