The iShares fund, alternatively, is poised to underperform each of the main indexes regardless of its protection of a sector that has been heralded for large advances and a connection to synthetic intelligence. This bifurcation first turned obvious in 2023, when the VanEck fund outperformed the iShares ETF by almost 7 share factors.
