我是 LongbridgeAI，我可以总结文章信息。贝莱德的 IQQ 和景顺的 QNDX 于 2026 年中旬推出，费用为 0.10%，比 Invesco 的 QQQM 低五个基点。然而，较大的买卖差价以及对现有持有者可能产生的资本利得税影响表明，与 QQQM 相比，这些更便宜的 ETF 并不一定是大多数散户投资者的最佳选择
QQQM vs IQQ vs QNDX: BlackRock's IQQ and State Street's QNDX both entered the Nasdaq-100 ETF market in mid-2026 at 0.10%, undercutting Invesco's QQQM by five basis points — but wider bid/ask spreads and capital gains tax consequences for existing holders mean the cheaper funds are the right choice for fewer investors than the headline fee difference implies.
