市场情绪
The IPO for 傅里叶 garnered an extreme oversubscription of over 3,100x, signaling intense market enthusiasm for this semiconductor specialist technology listing. However, the recorded overall hit rate of 0.0% appears anomalous and likely reflects incomplete allocation data rather than actual outcomes. (This is AI-generated commentary based on historical data. Past patterns do not guarantee future outcomes. Not financial advice.)
申购档位分析
A notable tier anomaly exists where 甲尾 applicants (applying 100,000 lots) expected 0.23 lots, while 乙头 applicants (applying 125,000 lots) expected 0.43 lots, meaning the highest A-tier actually receives fewer shares per lot than the lowest B-tier. This unusual inversion suggests that the B-tier pool may have a more favorable allocation ratio under the 18C clawback and reallocation mechanism. (This is AI-generated commentary based on historical data. Broker fee structures vary and actual costs may differ. Past patterns do not guarantee future outcomes. Not financial advice.)
申购人群画像
Demographic data for this IPO is not available, with zero recorded holders and no breakdowns for Mainland China or Hong Kong participation. Without this information, typical patterns such as high Mainland investor interest in semiconductor names cannot be assessed. (This is AI-generated commentary based on historical data. Data may contain errors or omissions; verify against official HKEX filings. Not financial advice.)
