我是 LongbridgeAI，我可以總結文章信息。貝萊德的 IQQ 和景順的 QNDX 於 2026 年中旬推出，費用為 0.10%，比 Invesco 的 QQQM 低五個基點。然而，較大的買賣差價以及對現有持有者可能產生的資本利得税影響表明，與 QQQM 相比，這些更便宜的 ETF 並不一定是大多數散户投資者的最佳選擇
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.
