A sharp KOSPI decline on what Korean media dubbed "Black Tuesday" drew public criticism, as the sell-off came despite the semiconductor industry posting its largest-ever earnings, highlighting a disconnect between record chip results and broader market sentiment.

Record Semiconductor Results Overshadowed by Market Slide

The claim centers on the paradox at the heart of the trading session: Korean semiconductor firms delivered record-breaking results, yet the KOSPI fell sharply enough to earn the "Black Tuesday" label, prompting complaints from investors and observers.

The plunge and the criticism it generated were the defining features of the day's coverage, with commentators questioning why a market anchored by record semiconductor profits could suffer such a steep drop.

Uncertainty Over Full Causes

The precise drivers of the sell-off — and how much of the decline can be attributed to factors beyond the semiconductor sector — remain not fully established. The extent to which record chip earnings failed to support the broader index, and what other forces contributed to the fall, is not definitively confirmed in the available record.

The market reaction nonetheless stands in clear tension with the earnings picture: the semiconductor industry's best-ever results did not prevent — nor visibly cushion — the KOSPI's steepest drop of the episode.

The claim that Korea's KOSPI tumbled on "Black Tuesday" despite the semiconductor sector posting record results, drawing criticism, is Mostly True.
