A post by a retail investor claiming hundreds of millions of won in profits from a concentrated bet on semiconductor stocks has drawn attention online.
A recent post on Blind, an anonymous workplace community, was titled “Latest update on the civil servant who went all-in with 500 million won on Hynix.”
The poster, identifying as the person in question, wrote, “Yes, that’s me,” and said he kept investing in semiconductor shares despite being mocked with warnings that “you’ll go broke investing like that.”
He said he made about 430 million won from January through April and posted a screenshot as proof.
The image shows cumulative realized profit and loss of about 439.37 million won from January to April 2026, for a return of about 6.72%. It also lists total purchases of about 6.5364 billion won and total sales of about 6.97578 billion won, with about 168.47 million won in profit in April alone.
The investor cited SK hynix and Samsung Electronics as key holdings, indicating a heavy focus on the semiconductor sector. He also wrote, “Semiconductors will keep trending upward through 2028,” signaling strong conviction about the market outlook.
Online commenters responded with remarks such as, “He proved it with results,” “Hynix surged on the first trading day of May, so it probably pumped even more from there,” and “I didn’t think it would turn out like that back then.” Others wrote, “Semiconductors will save Korea,” “foresight,” and “Should I sell Samsung Electronics and move to Hynix?”
As more retail investors share posts touting high returns, interest is rising again in “concentrated investment” strategies focused on specific sectors.
