Mostly True
Foreign investors posted an 8.5% return by concentrating on materials, parts and equipment ('sobjang' (소재·부품·장비)) and secondary battery stocks, while retail investors who stuck with semiconductor shares recorded a 7% loss, according to the data cited in the original claim.
The performance gap reflects sharply different positioning between the two investor groups. Foreign investors' allocation to sobjang (소재·부품·장비) and secondary battery names produced an 8.5% gain, whereas retail investors' continued commitment to semiconductor stocks left them down 7%.
The figures stem from the claim as originally published, and independent confirmation of the exact return percentages and the precise measurement period could not be established. The underlying search-based review was limited in scope, so the numbers should be treated as reported rather than fully validated.
The split underscores how sector rotation decisions — away from semiconductors and toward materials, parts and equipment, and secondary batteries — drove the gap between institutional-scale foreign flows and retail positioning over the period in question.
The claim that foreign investors earned 8.5% through sobjang (소재·부품·장비) and secondary battery holdings while semiconductor-focused retail investors lost 7% is largely supported by the available data, with the caveat that the exact figures remain unconfirmed.
Verdict: Mostly True
