開場白

大家好,歡迎收聽AI股市蝦聊。隔夜美股四大指數全線收黑,費半更是重摔超過3.8%,台指期夜盤同步跳水近2.4%。今天這集我們就來看看,AI模型怎麼解讀這波海外衝擊,對2026年10月20日(週二)的台股大盤怎麼判斷,順便誠實檢視一下最近的預測成績單。

今日大盤預測

現價 47111.26隔日看空 · 46443.52~46977.71 · 信心62%短線看空 · 45618.15~46812.64 · 信心62%
加權指數 AI 預測區間(隔日 / 短線)

服務目前只預測加權指數(TAIEX),分「隔日」(目標交易日2026-10-20,週二)與「短線」(自該日起約一週)兩個視野:

視野現價預測方向目標區間信心
隔日47111.26看空46443.52~46977.7162.0%
短線47111.26看空45618.15~46812.6462.0%

AI模型對週二大盤偏保守,隔日跟短線都看空,信心都落在62%左右,不算特別強烈。從盤面氛圍來看,上一份報告顯示大盤漲跌家數690漲、292跌,廣度還算健康,情緒上其實偏中性;只是現在疊加海外市場重挫的消息,短線氣氛明顯轉趨保守。

全球盤勢現況

以下僅為收盤現況,不含任何預測:

指數收盤漲跌%
台指期夜盤(TXF)46140-2.42%
道瓊工業指數(DJI)52002.41-0.34%
S&P 500(GSPC)7659.44-1.09%
那斯達克綜合指數(IXIC)26140.03-2.15%
費城半導體指數(SOX)11137.29-3.83%

費半重摔近4%,台指期夜盤也跟著跳水,這波對半導體權值股比重較高的台股來說,是明天開盤最值得留意的外部變數。

策略選股雷達

以下為策略篩選結果,非個股買賣預測:

股票綜合評分籌碼分本益比估值
陽明(2609)7710014.57偏貴
國泰金(2882)7288--
玉山金(2884)7210020.39偏貴
統一超(2912)7210020.18便宜
正新(2105)7110017.86便宜

近期預測命中率回顧

大盤·隔日64%(7/11)大盤·短線43%(3/7)
近期方向命中率(越高越準;含已結算樣本數)

老實說,近期大盤隔日預測的方向命中率是63.6%(11次猜對7次),平均誤差約0.92%,算是中規中矩;但拉長到短線一週的視野,命中率就掉到42.9%(7次中對3次),平均誤差也擴大到2.89%。這說明視野拉得越長,模型越難抓準,大家聽預測的時候要有心理準備,這些都是機率參考,不是穩贏保證。
