iShares Asia 50 ETF surges 52.7% YTD, driven by semiconductor giant TSMC's AI chip boom.

The iShares Asia 50 ETF (AIA) has surged 52.67% year to date through June 3, 2026, vastly outperforming the SPDR S&P 500 ETF Trust's 10.61% gain. This rally is primarily driven by semiconductor stocks, especially Taiwan Semiconductor Manufacturing Company (TSMC), which makes up 22.42% of the fund and has seen a 44.1% increase YTD due to strong AI chip demand and significant capital investments. Meanwhile, the China internet sector, including Alibaba and NetEase, has been a drag on the fund's performance. The fund's future depends on continued AI-related capital expenditure, stable geopolitical conditions in Taiwan and South Korea, and stabilization of China tech stocks. Essentially, AIA now acts as a leveraged bet on TSMC and related semiconductor companies rather than a broad Asia 50 index.
