TER、点差和隐藏成本
成本是长期收益的隐形敌人，小差异会累积成大结果。
要点
- 低 TER 不够
- 点差和佣金重要
- 成本要一起看
- 降低成本是确定收益
Visible and invisible costs
TER is the annual fund cost, but it is not the only one.
Bid-ask spread, broker commissions and operational taxes all affect the final result.
Why costs matter so much
Over long periods, costs compound just like returns.
A small annual difference can become huge after ten or twenty years.
Quick checklist
Compare two similar instruments by index, TER and liquidity.
Ask whether you are paying for extra complexity without receiving a concrete benefit.
现在该做什么
Before buying, compare at least two similar alternatives: every decimal saved today can become meaningful money tomorrow.
