預警 / 預測指標競技場
每日公開預測、到期自動回顧、依績效排名。每個指標背後都是可驗證的研究實驗。
歷來上架 6 個・現存 5 個・含已下架歷史(永久保留)
- 猜漲跌:看最近 60 次預測的命中率排名(命中率相同時,比平均賺賠 EV);附 binomial p-value 提醒樣本不大時別把運氣當實力。
- 估風險範圍(警戒線 / 區間類):看最近 250 次的實際失守率有沒有貼近理想值(例:說好 5% 的日子會失守,實際就該接近 5%,太多太少都算不準);附 Kupiec 檢定 p-value。
- 累積滿 20 次驗證才入榜;不足者顯示「樣本累積中」。
- 所有預測發布當下就蓋時間戳,事後不能改;遲發的標記「遲發」、不計入排名。紀錄只增不改,發現錯誤用更正單沖正、原紀錄保留。
- 表現差的指標自動降級「觀察」,觀察期內未回升即下架 — 下架指標的全部歷史永久公開保留。
美股→台股隔夜領先訊號
上架 2026/06/11・時效 1 交易日
昨晚美股收漲 — 預測今天台灣 0050 跟著漲
指標值 0.0010預測對象日 2026-07-27
技術參數:方向:看漲
發布 2026/07/25 07:00驗證 2026/07/27 13:30 後
投資上怎麼用:開盤前先知道今天是順風還是逆風:看跌日一般會避免開盤追高,看漲日則不必急著恐慌出場。
訊號規則:SPY t-1 日(台北時間今晨 05:00 收盤)close-to-close 報酬 > 0 → 預測 0050.TW 今日(t)close-to-close 上漲;≤ 0 → 下跌。訊號全部來自 t-1 完成值,lag 明確。
預測目標:0050.TW close-to-close return t(當日報酬方向)
已知限制:預測力真實但 alpha 集中在開盤 gap(K521),現貨 0050.TW 在此時間窗口不可交易。Arena 只評方向命中率,不宣稱可交易。

VIX 危機預警(台股風險燈號)
上架 2026/06/11・時效 1 交易日
風險燈正常:沒有偵測到危機訊號 — 預期台股今天不致大跌
指標值 18.580預測對象日 2026-07-27
技術參數:note:'up' encodes the rule's 'not-down (>=0)' prediction; review scores hit as actual_return > 0|方向:看漲|風險燈:normal
發布 2026/07/25 07:00驗證 2026/07/27 13:30 後
投資上怎麼用:紅燈日一般做法是不搶反彈、不留大部位過夜;綠燈不代表會漲,只代表沒偵測到危機訊號。
訊號規則:VIX_{t-1} 日變化 > +10%(spike)OR VIX_{t-1} > 25(high level)→ 亮「風險」燈,預測 0050.TW 今日下跌;否則「正常」燈,預測不跌(≥0)。複合規則防 spike 單獨全期劣於 BH(設計文件 §6 C5 誠實揭露)。lag 明確:均用 t-1 收盤值。
預測目標:0050.TW 當日報酬方向(條件預警型)
已知限制:預警型指標:大多數日子預測「不跌」,base rate 高。EV_60 與「風險燈亮時的條件命中率」將分開顯示,防 base-rate 虛胖。全期 spike 單獨弱於 BH(K817 全期誠實揭露)— 上架規則用複合 spike+level。
來源實驗:K817
OOS 驗證證據(1 項)▶
- note:
- OOS 2023-2024: spike guard Sharpe 1.2116 > BH 1.0271. HONEST: full-period spike guard alone Sharpe 0.1107 < BH 0.1401 — hence rule uses spike+level composite. Arena evaluates direction hit under composite rule, not just spike alone.

VIX 短端期限結構→SPY 波動方向
上架 2026/06/11・時效 5 交易日
市場的短期避險情緒升溫 — 預測未來一週美股震盪會變大
指標值 -0.0531預測對象日 2026-07-31
技術參數:meaning:up = SPY next-5d RV > prev-5d RV (RV proxy r^2*252, 5d mean)|方向:看漲
發布 2026/07/25 07:00驗證 2026/08/01 04:00 後
投資上怎麼用:預期震盪變大時,一般做法是降低槓桿、縮小部位、避免重押;預期震盪變小才考慮加碼。
訊號規則:log(VIX9D_{t-1} / VIX_{t-1}) > rolling 60d 中位數 → 預測 SPY 未來 5 個交易日 RV 高於前 5 日 RV;反之預測下降。lag 明確(均用 t-1 值)。
預測目標:SPY 5d realized vol 升/降方向
已知限制:K1415 evidence is QLIKE continuous scale (volatility forecasting). Binary direction (higher/lower vol) is an Arena simplification; empirical direction hit rate will be tracked forward by Arena itself. 方向化是合理化簡,但命中率由 Arena 前向驗證。
來源實驗:K1415

A4f-VIX9D-t 明日 SPY 2.5% VaR
上架 2026/06/11・時效 1 交易日
模型畫出明天美股(SPY)的「罕見大跌警戒線」:單日跌超過 1.9% 的機率只有 2.5%
指標值 -0.0192預測對象日 2026-07-27
技術參數:unit:1-day log return (decimal)|alpha:2.50%|2.5% VaR:-1.92%
發布 2026/07/25 07:00驗證 2026/07/28 04:00 後
投資上怎麼用:可當作「今天的停損深度參考」:把部位控制在就算真的碰到警戒線、損失也還能承受的水準。
訊號規則:GARCH-X(A4f spec,VIX9D² driver,Student-t)每日 refit/filter 後輸出明日 2.5% VaR;訊號用 t-1 收盤前全部資訊,lag 明確。
預測目標:SPY 明日報酬是否跌破 VaR(期望 violation rate 2.5%)
已知限制:SPY-specific。QQQ 上 VIX9D 增益不顯著(DM t=-2.33)— 此指標不外推至其他資產。校準組評的是 violation rate 準確度,非方向。

發布 2026/07/25 07:00驗證 2026/07/28 04:00 後
投資上怎麼用:看它和 GARCH 警戒線差多遠:兩條線接近代表模型有共識;差很遠代表市場不確定性高,當天宜更保守。
訊號規則:HAR-RV 預測變數上跑 quantile regression(τ=0.05),rolling refit(每 ~21 交易日),輸出明日 5% VaR。訊號用 t-1 已知資訊,lag 明確。
預測目標:SPY 明日 5% VaR violation 校準
已知限制:與 C3(garch_vix9d_spy_var25)同 target 不同方法 — 兩個 VaR 指標同台互比是 Arena 看點之一。HAR-QR 無 volatility driver(無 VIX9D),為純 RV 自迴歸方法的代表。

發布 2026/06/11 17:44驗證 2026/06/12 04:00 後
訊號規則:HAR-RV 分位數迴歸輸出各資產明日 RV 的 q95 上界;違規 = 明日 realized vol 突破上界(期望 violation rate 5%)。三資產各自獨立計算。訊號用 t-1 已知資訊,lag 明確。
預測目標:QQQ/GLD/TLT 明日 RV ≤ q95 上界(尾部校準)
已知限制:Point forecast 是 NULL(dm_status=SIG_NEG)— 不得宣稱此指標能預測 RV 水準,只能宣稱 q95 尾部區間校準。Arena 只評校準面(violation rate 是否接近 5%)。
來源實驗:K1403
OOS 驗證證據(1 項)▶
- note:
- Point forecast DM all sig-neg (method cannot beat OLS median). Tail (q95) calibration USABLE for all 3 assets. Arena only uses tail calibration face, consistent with TAIL_CALIB_USABLE verdict.

- —狀態未知editorial: 投資實用價值不足(非績效因素)— q95 RV 上界屬統計校準練習,一般投資人無法據此做出操作決策(boss 2026-06-11 指示指標須具投資實用性)。歷史訊號與回顧永久保留。
