Chip and display heavyweights anchor the market

The 48.2% figure reflects the combined weight of semiconductor and display businesses within overall market capitalization. The concentration is driven largely by industry leaders such as Samsung Electronics and SK hynix, whose semiconductor operations — spanning memory chips, foundry services and related hardware — represent the single largest bloc of listed equity value.

Concentration carries both strength and risk

Such a high share means the broader market's performance is closely tied to the semiconductor cycle. Memory demand, HBM orders linked to the AI boom, and foundry utilization rates all feed directly into headline index levels, amplifying both gains and losses for investors.

The display side of the calculation adds the weight of panel makers, whose valuations move with television, monitor and mobile device demand. Together, the two sectors form a foundation that shapes how Korean equities are perceived by global funds tracking hardware and AI supply chains.

The claim that semiconductors and displays account for 48.2% of total market capitalization is True.

Verdict: True
