SPY如何運作
- 標普500規則
- 篩選企業與分配權重
- SPY基金持倉
- 你持有的ETF份額
2. 公司多，不等於風險完全分散
標普500採流通市值加權，非等權重。大企業影響較大；行業較廣仍可能有頭部集中風險。與QQQ可能重疊，組合前應核對權重。

3. 收益從哪裡來？
收益來自盈利、估值變化與分配。價格收益不含股息再投資，總收益包含。發行商公布年度總費率0.0945%，於基金內扣除；價差、券商費用與稅費亦影響結果。

4. 理解可能的下行風險
衰退、通膨、利率與盈利不如預期可能造成大幅虧損。下跌20%需上漲25%回本。52週回撤不同於歷史最高點回撤；本幣收益亦受匯率影響。

5. 開始研究的清單
先看組合定位、持有期限、重疊與可承受虧損。比較相同日期、貨幣與股息口徑。TTM為歷史已報告盈利，Forward依賴預測；歷史百分位並非未來漲跌機率。

6. 常見問題
SPY不保本。每股價格低未必估值低。費用與交易令實際收益不同於指數。SPY行業通常比QQQ更廣，但同時持有不消除重疊风险。

Investment Discipline
- Buying SharesBuy in stages only below the 25th percentile; do not add shares merely because valuation is fair.
- 25%–75% Fair ValueHold. Cash-secured puts at lower strikes may be used while waiting for a better entry.
- 75%–95% ExpensiveKeep high-quality holdings; after sharp gains, high-strike covered calls may add cash flow.
- Above 95% Bubble ZoneThis is the only zone where gradually trimming shares to realize gains may be considered.
