TER、スプレッド、隠れコスト
コストは長期投資の静かな敵です。小さな差が時間とともに大きくなります。
重要ポイント
- 低TERだけでは不十分
- スプレッドと手数料も重要
- コストは合計で見る
- コスト削減は確実な改善
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.
