Welcome to "AI Stock Chat." Today is Tuesday, October 27, 2026. The Taiwan stock market saw a fairly significant correction today. Did it make your heart race? Don't worry, today we will once again use the most honest, unvarnished AI quantitative data to help you prepare for the next trading day, Wednesday, October 28, 2026. Let's dive right in! ## Today's Market Forecast
Current Price 46041.43Next-DayBearish · 45388.85~45910.91 · Confidence 69%Short-TermBearish · 44582.23~45749.59 · Confidence 69%
TAIEX AI Forecast Range (Next-Day / Short-Term)
This service only forecasts the Taiwan Capitalization Weighted Stock Index (TAIEX), offering two horizons: "Next-Day" and "Short-Term." | Horizon | Current Price | Forecast Direction | Target Range | Confidence | | --- | --- | --- | --- | --- | | Next-Day (10/28) | 46041.43 | Bearish | 45388.85~45910.91 | 69.0% | | Short-Term (1 Week) | 46041.43 | Bearish | 44582.23~45749.59 | 69.0% | According to the AI model's latest predictions, both the next-day trend for October 28 and the short-term trend for the coming week show "bearish" signals, with confidence levels at 69.0%. Overall market sentiment is currently pessimistic, with the TAIEX down 1.81% and market breadth showing decliners outnumbering advancers (248 gainers, 766 decliners). Tomorrow's index target range is estimated to fall between 45388.85 and 45910.91 points, so a bit of extra caution might be warranted in your trading. ## Key Stock AI Forecasts Honesty and transparency are our core principles. In today's database, the AI model did not generate prediction data meeting our confidence standards for any specific key stocks. We never fabricate or pad data just to fill space. Today, we will report the facts as they are: there is currently no individual stock forecast data, so let's focus our attention on the broader market and our strategy screening instead! ## Global Market Status Taiwan Index Futures (TXF) night session and the four major US indices / Philadelphia Semiconductor Index only show "current status," **no forecasts are provided**. | Index | Close | % Change | | --- | --- | --- | | Taiwan Index Futures Night Session (TXF) | 45654 | -1.25% | | Dow Jones Industrial Average (DJI) | 52361.58 | 0.28% | | S&P 500 Index (GSPC) | 7676.77 | 0.7% | | Nasdaq Composite (IXIC) | 26169.38 | 0.82% | | Philadelphia Semiconductor Index (SOX) | 11083.47 | 2.82% | ## Strategy Stock Screener Radar The following are strategy screening results, **not buy/sell predictions for individual stocks**. | Stock | Overall Score | Institutional Flow Score | P/E Ratio | Valuation | | --- | --- | --- | --- | --- | | Hotai Motor (2207) | 77 | 100 | 13.03 | cheap | | Wistron (3231) | 77 | 100 | 15.09 | cheap | | Wan Hai (2615) | 76 | 100 | - | - | | Quanta Computer (2382) | 74 | 100 | 14.03 | cheap | | Chang Hwa Bank (2801) | 74 | 100 | - | - | - **Hotai Motor (2207)**: Overall score is 77, institutional flow score is a high 100, and valuation is cheap. The current buy/sell signal score is 0.0, indicating no clear buy or sell signals today. Current technical characteristics show a bullish alignment across short, medium, and long-term moving averages. The stock price has broken above the monthly moving average, showing a medium-term bullish bias. Additionally, the short-term KD indicator is pointing upward, and the RSI is at 52, which is in a healthy, neutral-to-warm range. - **Wistron (3231)**: Overall score is 77, institutional flow score is 100, and valuation is cheap. The current buy/sell signal score is 0.5. Bullish factors include the 5-day moving average crossing above the 20-day moving average (MA5 golden cross MA20) and the CCI momentum indicator reaching 123.07, indicating strengthening momentum. However, there are bearish factors to watch out for, including a death cross in the KD indicator at high levels and a bearish engulfing candlestick pattern signaling potential weakness. - **Wan Hai (2615)**: Overall score is 76, institutional flow score is 100. The current buy/sell signal score is 0.0, indicating no clear buy or sell signals today. Technically, it maintains a bullish alignment across short, medium, and long-term moving averages. The stock price is holding steadily above the monthly moving average, showing a medium-term bullish bias. The short-term KD indicator is pointing upward, and the RSI is at 56. - **Quanta Computer (2382)**: Overall score is 74, institutional flow score is 100, and valuation is cheap. The current buy/sell signal score is 0.0. Although there is no clear buy or sell signal today, the moving averages are currently entangled with no clear direction, and the stock price has fallen below the monthly moving average. Technical indicators suggest a strong wait-and-see sentiment in the market, with an RSI of 45 and a downward-pointing short-term KD indicating short-term weakness. - **Chang Hwa Bank (2801)**: Overall score is 74, institutional flow score is 100. The current buy/sell signal score is 0.8. Bullish factors include strengthening momentum (CCI at 144.18) and a volume-price bullish divergence signaling stabilizing volume. However, the bearish factor is that Williams %R has reached -1.82, indicating short-term overbought conditions, so investors should be cautious about chasing highs. ## Recent Prediction Accuracy Review
