A poll found a difference in stock investment returns between supporters of the Democratic Party of Korea and supporters of the People Power Party. Among Democratic Party of Korea supporters, a higher share said they made profits from stock investing, while among People Power Party supporters, a higher share said they did not.
Korea Gallup on the 21st released findings from a survey conducted on the 18th–20th of 1,004 people nationwide aged 18 and older, including 432 who had invested in domestic stocks this year, asking about their party support and more. Of the 432, 42% said they "made a profit (in the black)," while 40% said they "took a loss (in the red)." Another 17% said they "neither made a profit nor took a loss," and 1% withheld an opinion.
Of the 432 stock investors, 198 supported the Democratic Party of Korea; among them, 47% said they made a profit and 35% said they took a loss. By contrast, among the 107 People Power Party supporters, 34% said they made a profit and 48% said they took a loss. Among Democratic Party of Korea supporters, more were in the black, and among People Power Party supporters, more were in the red.
Evaluations of President Lee Jae-myung also diverged. Among 183 profit-makers, 59% viewed Lee's job performance positively, while among 171 loss-takers, 63% gave a negative assessment.
On this gap, Choi Byung-chun, a senior adviser at Shin & Kim LLC, wrote on Facebook, "The biggest variable that determines whether one is 'in the black/in the red' is whether the 'purchase timing' was early or late," adding, "Because Democratic Party of Korea supporters had confidence in 'Commercial Act revisions,' they likely entered in the second half of 2025 or, at the latest, in January–February 2026, while People Power Party supporters, due to critical coverage by conservative media of 'Commercial Act revisions,' were less likely to enter in the second half of 2025, and, after the KOSPI hit 5,000 at the end of January 2026 and continued to rise even after the Iran war, likely joined 'very belatedly' after seeing that."
Looking at the outlook for KOSPI fluctuations over the next year, 37% of all respondents said it would "rise," while 29% expected it to "fall." Among stock investors, 50%—half—said it would "rise."
The survey was conducted through live interviewer calls to randomly generated mobile virtual numbers. The margin of error is ±3.1 percentage points at the 95% confidence level, with a contact rate of 45.6% and a response rate of 10.0%.
