Welcome to today's episode of "AI Stock Chat". With Friday's trading session just wrapped up, are you all ready to welcome the weekend? However, investing never takes a holiday. Today, we are going to take an early look at the AI model's latest quantitative predictions for the first trading day of next week, Monday, November 2, 2026, covering the TAIEX and key individual stocks, helping you stay ahead of the curve! ## Market Forecast
Current Price 46368.33Next-DayBearish · 45551.75~46205.01 · Confidence 75%Short-TermBearish · 44542.39~46003.14 · Confidence 75%
TAIEX AI Prediction Range (Next-Day / Short-Term)
| Horizon | Current Price | Predicted Direction | Target Range | Confidence | | --- | --- | --- | --- | --- | | Next-Day (11/02) | 46368.33 | Bearish | 45551.75~46205.01 | 75.0% | | Short-Term (1 Week) | 46368.33 | Bearish | 44542.39~46003.14 | 75.0% | On Friday, October 30, the TAIEX closed at 46,368.33, down 1.42%. Market sentiment was clearly conservative, with declining stocks outnumbering advancing ones by 745 to 235. The AI model's outlook for next Monday, November 2, is also bearish, predicting that the index may continue its correction, with a target range between 45,551 and 46,205 points and a confidence level of 75%. The short-term weekly trend is also viewed as bearish, so please remain vigilant and focus on defensive strategies in your trading. ## Global Market Overview | Index | Close | % Change | | --- | --- | --- | | Taiwan Index Futures Night Session (TXF) | 45926.00 | -1.38% | | Dow Jones Industrial Average (DJI) | 52342.56 | -0.25% | | S&P 500 Index (GSPC) | 7720.39 | -0.30% | | Nasdaq Composite (IXIC) | 26184.73 | -1.38% | | Philadelphia Semiconductor Index (SOX) | 11518.20 | -1.42% | Looking at international markets, both US stocks and the Taiwan Index Futures night session performed poorly on Friday. The Taiwan Index Futures night session plunged 1.38%, breaking straight through the key psychological level of 46,000 points. In the US, while the Dow and S&P 500 saw only minor corrections, tech and semiconductor stocks suffered heavy losses, with the Nasdaq dropping 1.38% and the Philadelphia Semiconductor Index (SOX) tumbling 1.42%. It is no wonder our AI model has issued a bearish forecast for the TAIEX next Monday. ## AI Predictions for Key Stocks Many listeners often ask if AI can predict the ups and downs or target prices of individual stocks. I want to be completely honest with you: our AI model currently *only* predicts the direction and range of the TAIEX. We do not provide any buy/sell recommendations, target prices, or bullish/bearish forecasts for individual key stocks. However, we use multi-factor quantitative screening to analyze market-focus stocks from technical, institutional flow, and valuation perspectives. This brings us to our "Strategic Stock Selection Radar". We let the data speak for itself to help you break down the strength and weakness factors of individual stocks! ## Strategic Stock Selection Radar (The following are strategic screening results, not buy/sell predictions for individual stocks) | Stock | Overall Score | Institutional Score | P/E Ratio | Valuation | | --- | --- | --- | --- | --- | | Formosa Chemicals (1326) | 73 | 100 | 31.53 | Fair | | Quanta (2382) | 73 | 100 | 13.86 | Cheap | | Fubon Financial (2881) | 72 | 100 | N/A (Financial Stock) | Not Evaluated (Refer to P/B) | | President Chain Store (2912) | 72 | 100 | 19.89 | Cheap | | Foxconn (2317) | 71 | 100 | 16.35 | Fair | *Note: Due to the nature of financial stocks, Fubon Financial (2881) is not suited for standard P/E ratio and valuation metrics. Investors are advised to use the Price-to-Book (P/B) ratio instead to evaluate its value, avoiding bias from relying on a single indicator.* Next, let me break down the quantitative details of these five focus stocks for you: * **Formosa Chemicals (1326)**: Overall score of 73, with a perfect score in institutional flow. However, its bull-bear momentum indicator scored 0.0 today (on a scale of -2 to +2, indicating balanced forces and a wait-and-see stance). Technically, the short, medium, and long-term moving averages show a bullish alignment, and the stock price is above the monthly moving average, indicating a bullish medium-term trend. However, note that the short-term KD indicator is pointing downward. * **Quanta (2382)**: Overall score of 73, institutional score of 100, and valuation falls into the "cheap" range. The bull-bear momentum indicator is also at 0.0. Currently, the moving averages are tangled with no clear direction, and the stock price has fallen below the monthly moving average, indicating a weaker medium-term trend. However, the short-term KD indicator is pointing upward. * **Fubon Financial (2881)**: Overall score of 72, institutional score of 100. The bull-bear momentum indicator is at a bullish 0.8. On the technical side, a bullish hammer candlestick pattern has appeared, and the CCI momentum is strengthening. However, be cautious as Williams %R has reached -18.52, indicating short-term overbought conditions, so avoid blindly chasing highs. * **President Chain Store (2912)**: Overall score of 72, institutional score of 100, with a cheap valuation. The bull-bear momentum indicator is slightly bearish at -0.5. Although the CCI shows strengthening momentum, a high-level death cross has appeared on the KD indicator, which is a warning sign of weakening technicals. * **Foxconn (2317)**: Overall score of 71, institutional score of 100, with a fair valuation. The bull-bear momentum indicator is at a bullish 1.5. The primary bullish factor is the MACD histogram turning positive, indicating that upward momentum is strengthening. ## Recent Accuracy Review
TAIEX · Next-Day44% (8/18)TAIEX · Short-Term57% (8/14)
Recent Directional Accuracy (higher is better; includes settled sample size)
We value honesty and transparency above all, reporting both the good and the bad. Looking back at our recent TAIEX prediction performance: For "Next-Day Predictions", our directional accuracy was actually not very ideal, standing at only 44.4% (8 out of 18 times correct). However, the range hit rate was 5/18, with the average error controlled at 1.16%. For "Short-Term Weekly Predictions", the performance was slightly better, with a directional accuracy of 57.1% (8 out of 14 times correct), a range hit rate of 3/14, and an average error of 2.3%. The data is right in front of us: AI is not omnipotent, and the direction won't always be correct. Therefore, please only use these predictions as a reference and make sure to manage your capital and risk properly! ## Disclaimer This content is automatically generated by an AI model based on quantitative data and is for research and reference purposes only.
