Why Taiwan’s AI moat trumps South Korea's memory bet: Manishi Raychaudhuri
SMH•Taiwan's TAIEX has fallen 20% from its October 6 high, compared with a 44% drop in South Korea's KOSPI from its June 22 peak. The author argues Taiwan's broader AI supply chain and companies' competitive moats contrast with South Korea's concentrated, cyclical memory exposure.
1. Different AI exposures
The author says Taiwan's technology opportunities span the AI supply chain, including chipmaking, design, packaging, server assembly, and power and cooling systems. By contrast, South Korea's AI exposure is concentrated in Samsung Electronics and SK Hynix, which together make up roughly half of the KOSPI; other technology companies account for 6%.
2. Valuation and concentration
Taiwan's TAIEX is up 35% year to date, compared with about 17% for the KOSPI. FactSet consensus forecasts put Taiwan's forward P/E at 14.4, more than three times South Korea's 4.1. The author says reliance on cyclical memory prices and retail margin debt could make South Korea more vulnerable to further volatility.
3. Taiwan's competitive moats
The article says TSMC controls 73% of the pure-play foundry market and 90% to 99% of the market for the smallest advanced chips; Hon Hai controls 40% of AI server assembly and is targeting 50% within two years. The author notes Taiwan's current valuation premium over South Korea is 260%, versus a 10-year average of 50%, and says the gap may attract bargain hunters but Taiwan's structural advantages remain.
