Model and entertainer Byun Jung-soo revealed on the YouTube channel 'Bolppalgan Nyonyonyonnyon' on the 15th that she used generative artificial intelligence (AI) to find success in stock investing, sharing travel stories from a trip to Bangkok, Thailand, with actress Bae Jong Ok and singer-turned-entertainer Yoon Hyeon Suk. While checking a shopping list, Yoon told Byun, "If you ask ChatGPT, it actually tells you quite well," and Byun responded, "I actually started investing in stocks because of it." Byun explained she started buying "just one or two shares at a time last September" and that "they ended up rising significantly." She stated, "Now, I have withdrawn my principal and am operating only with the interest." When Bae asked, "So how much did it go up?" Byun mentioned SK Hynix, saying, "As of the time of filming, SK Hynix has risen a lot," prompting Bae to ask, "Didn't it rise almost twofold?" The article notes that Byun's case illustrates how individuals are using new digital tools to study markets, though experts advise investors must still consider market volatility and risk factors.
