IWDA is arguably the most widely held ETF among European long-term investors. iShares Core MSCI World UCITS ETF from BlackRock manages over $95 billion and is the gold standard for anyone wanting developed-world equities in a single fund. Does it still deserve its reputation in 2026? Let's break it down.
