Hyosung Heavy Industries' stock price has become the highest-priced stock on the domestic stock market, and the story of an individual investor who claimed to have invested in the stock in the past is going viral online. According to the claim, stocks purchased before being imprisoned have reached a value of over 100 billion won after their release.
The author claimed that before being incarcerated in 2020, he used about 260 million won in jeonse (lump sum housing lease) funds to purchase 30,000 shares of Hyosung Heavy Industries8,530 won per share. At that time, the stock price of Hyosung Heavy Industries had plunged to a record low due to the impact of COVID-19.

After being released, he said that upon checking the account, the valuation had exceeded 100 billion won. He wrote, "If I hadn't gone to prison, I probably would have sold in the middle," noting that being forced to hold the stock for a long period ultimately led to significant profit. This story has quickly spread across social media and online communities.
However, it has not been confirmed whether the story is true. Considering the trading volume at that time, some analysts point out that it would have been difficult for an individual investor to purchase such a large quantity of shares near the bottom all at once. There are also suspicions that this may be an exaggerated or sensationalized investment success story.
Recent analyses suggest that the surge in Hyosung Heavy Industries' stock price is driven by the expansion of the AI industry. As the number of AI data centers increases, power consumption is also rising rapidly, leading to a sharp increase in demand for power equipment such as transformers, circuit breakers, and power transmission and distribution facilities. The market perceives this as a new supply shortage cycle following the semiconductor sector.

Hyosung Heavy Industries is experiencing rapid growth in its performance alongside the trend of expanding power grid investments in North America. Last year, it posted record-high results, and its order backlog also increased significantly. The market is paying attention to the possibility that the demand for power infrastructure in the AI era will continue to rise, leading to further growth in performance for the foreseeable future.
Experts warn that such cases could excessively stimulate investor sentiment. In fact, online, there are reactions such as "Did I miss out too?" and concerns are being raised that this could fuel a growing 'FOMO' (Fear of Missing Out) mentality, leading investors to jump in at a late stage.
