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 7 個・現存 6 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);排名看「偏離 ÷ 抽樣誤差」,目標水準不同的指標才能公平比較;附精確二項檢定 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。
- 每筆訊號都記錄發布時間;到期後回顧結果並更新排名。訊號、回顧與既有下架指標的歷史紀錄永久保留。
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 17.200預測對象日 2026-10-30
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 2026/10/30 07:00驗證 2026/10/30 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。

- 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.

昨晚美股收跌 — 預測今天台灣 0050 跟著跌
指標值 -0.0038預測對象日 2026-10-30
技術參數:方向:看跌
發布 2026/10/30 07:00驗證 2026/10/30 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。本指標在 Arena 評估方向命中率,不宣稱可交易。

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 2026/10/30 07:00驗證 2026/11/06 05:00 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。

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 1.6% 的機率只有 2.5%
指標值 -0.0158預測對象日 2026-10-30
技術參數:unit:1-day log return (decimal)|alpha:2.50%|2.5% VaR:-1.58%
發布 2026/10/30 07:00驗證 2026/10/31 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 2026/10/30 07:00驗證 2026/10/31 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。

美股→台股隔夜領先訊號 v2(SPY+TSM+SMH)
上架 2026/10/10・時效 1 交易日
prob up:35.39%|方向:看跌
指標值 0.3539預測對象日 2026-10-30
發布 2026/10/30 07:00驗證 2026/10/30 13:30 後
訊號規則:SPY、TSM(台積電 ADR)、SMH 在 t-1 美股日(台北時間今晨收盤)的 close-to-close 報酬(百分比)餵給邏輯迴歸:logit P(0050.TW 今日 t 收盤上漲) = b0+b1·SPY+b2·TSM+b3·SMH;係數每個曆月重估一次,只用該月之前已結束的全部樣本(擴張窗,K1966 模型 M1)。P > 0.5 → 預測 0050.TW 今日(t)close-to-close 上漲;P ≤ 0.5 → 下跌。訊號全部來自 t-1 完成值,lag 明確。v1(us_tw_overnight_lead,只用 SPY 前一日報酬的符號)並行保留對照。
預測目標:0050.TW close-to-close return t(當日報酬方向)
已知限制:【預註冊 §7(逐字)】目標是 0050.TW 的收盤對收盤方向,其漲跌多數發生在開盤跳空(K502:收盤對收盤超額報酬的 77–93% 落在隔夜跳空,不可交易);本題的任何顯著結果都不是可交易訊號,也不含交易成本。 結論只針對 0050.TW、SPY、TSM、SMH 與釘住的快照;0050 是 TAIEX 的代理,不是官方指數。 報酬使用快照取得日的 `adj_close`,股利還原因子是取得日的事後值(它使 `adj_close` 與 `close` 的單日報酬在部分日期不同;本實驗沒有取得除息事件的獨立資料,不陳述這些日期是哪些日子,也不陳述頻率),本實驗不重建當時可得的未調整序列,結果標為事後還原價格上的偽即時樣本外。 【預註冊 §8(逐字)】因此「TSM、SMH 對 0050 方向有增量資訊」這一點為盲,SPY 基準的強度為非盲。下游引用任何結論時須帶上這個限定。 【Arena】本指標在 Arena 評估方向命中率,不宣稱可交易。v2 與 v1 並行累計,兩者以同一 target 日、同一判定器、同一口徑比較;K1966 樣本外期間的符號規則命中率與 Arena 前向命中率期間與樣本不同,不可直接比較,也不得當作本指標的前向績效。【投資上怎麼用(通用教育性說明,非個人化建議)】這是台股開盤前的隔夜方向背景參考:模型機率偏高或偏低,只代表美股大盤與半導體的隔夜表現與 0050 當日收盤相對前一收盤的方向較常一致;它不是買賣訊號,現貨在此時間窗口不可交易。

- note:
- Nested comparison M1 (SPY, TSM, SMH) against M0 (SPY only), out-of-sample probability forecasts of 0050.TW closing up, Brier loss, Clark-West. The evidence is a close-to-close probability forecast comparison on ex-post adjusted prices, not a forward result and not a tradable signal; the forward hit rate of this indicator accumulates in the Arena from its listing date and is compared with v1 on the same target days, scored by the same resolver.

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。本指標在 Arena 評估校準面(violation rate 是否接近 5%)。
