Bid-Ask Spread
trading-basics
무슨 뜻인가요
The difference between the highest price a buyer is willing to pay (bid) for an asset and the lowest price a seller is willing to accept (ask). Tighter spreads mean lower trading costs.
예시
If an ETF has a bid price of $100 and an ask price of $100.05, the bid-ask spread is $0.05. On a 100-share trade, your total trading cost from the spread is $5.
초보자가 흔히 하는 실수
Beginners ignore bid-ask spreads, especially on low-volume or niche ETFs. Wide spreads can eat into your returns every time you buy or sell, even if the ETF itself performs well.
