Thanh khoản ETF
Tại sao khả năng giao dịch của một ETF phụ thuộc vào tài sản cơ sở của nó, chứ không chỉ vào khối lượng giao dịch của chính nó.
An ETF has two layers of liquidity: the visible layer (its own trading volume and quoted spread) and the deeper layer (the liquidity of what it holds). Because APs can create and redeem shares, a low-volume ETF holding liquid large-cap stocks can still absorb large orders near fair value.
That said, screen liquidity still matters for everyday investors: funds with tiny volume tend to quote wider bid/ask spreads, and market orders in them can execute at poor prices. Assets under management, average volume, and typical spread together give a fuller picture — this site shows volume and AUM on every fund page.
Practical habits: prefer limit orders, avoid the market open and close, and be extra careful with funds holding assets that trade in other time zones.
