On.cc · 1 SOURCESabout 7 hours ago5 MIN

Summary
Hong Kong financial commentator Gong Cheng (龔成) has issued a stark warning about the dangers of momentum-driven investing, illustrating his point with a cautionary tale of a printed circuit board company whose stock surged from HK$1 to HK$100 before collapsing. Gong, a licensed securities practitioner and author of multiple best-selling finance books, emphasizes that retail investors who ignore business fundamentals often learn expensive lessons when prices inevitably diverge from underlying value. The incident highlights how stocks without genuine business support can inflict catastrophic losses on those who buy based purely on speculative fever rather than analysis.
Key Points
- The stock began rising from HK$1 due to favorable factors, reaching HK$2-3 within months—a pace that already exceeded what the company's printed circuit board business fundamentals could justify .
- Within one month, the stock climbed above HK$10 despite having no substantive business developments, entering what Gong describes as a "crazy phase" driven entirely by market sentiment .
- The stock surged to HK$100 in just a few days, likely setting a Hong Kong record for the fastest rise from HK$1 to HK$100, but collapsed to HK$30 that same afternoon .
- Dozens of investors bought at HK$100, with one standard lot of 2,000 shares costing HK$200,000; one month later, the stock fell below HK$3, resulting in losses of HK$194,000 per lot .
- Gong stresses that stocks without underlying value never return to their previous highs, leaving investors who chased momentum with no path to recovery .
Why It Matters
This case serves as a powerful reminder for Hong Kong retail investors about the importance of fundamental analysis before committing capital. The rapid rise and catastrophic fall demonstrates how speculative manias can destroy wealth in a matter of weeks, particularly when investors act on the belief that "past doublers will double again." As Hong Kong's market continues to attract retail participation, such warnings underscore the need for financial literacy and disciplined investment approaches over get-rich-quick mentality.
