Although the Taiwan stock market was closed today, Wednesday, September 9, 2026, the storm in the US markets and institutional chip flows hasn't stopped. In this episode, we'll analyze and predict the market trend for the next trading day, Thursday, September 10, 2026. With foreign institutional investors holding historically massive short positions, can tomorrow's line of defense hold? Should beginners jump in to catch the rebound? Let's dive in! ## Today's Market Prediction
Current Price 47105.78Next-DayBearish · 46438.12~46972.25 · Confidence 66%Short-TermBearish · 45612.84~46807.19 · Confidence 66%
TAIEX AI Prediction Range (Next-Day / Short-Term)
Our AI service focuses solely on predicting the Taiwan Capitalization Weighted Stock Index (TAIEX), providing two perspectives: "Next-Day" and "Short-Term". Here is the latest prediction data for Thursday, September 10, 2026: | Perspective | Current Price | Predicted Direction | Target Range | Confidence | | --- | --- | --- | --- | --- | | Next-Day (09-10) | 47105.78 | Bearish | 46438.12~46972.25 | 66.0% | | Short-Term (1 Week) | 47105.78 | Bearish | 45612.84~46807.19 | 66.0% | Based on the AI model's data, the outlook for the broader market on Thursday, September 10, 2026, is conservatively "Bearish" with a confidence level of around 66%. The key tomorrow lies in whether the TAIEX can hold its starting point of the recent rally. Although US semiconductor indices have shown support, foreign institutional investors currently hold historically massive short positions in futures. This creates heavy pressure on the chip side, and we expect more declining stocks than advancing ones. I suggest that beginners adopt a wait-and-see approach for now and avoid catching a falling knife to chase a rebound. ## Global Market Status Here is the latest closing status of the TAIEX futures night session and the four major US stock indices. Please note that this section **only presents objective market data and does not represent the AI's prediction direction**: | Index | Close | Change % | | --- | --- | --- | | TAIEX Futures Night Session (TXF) | 47055 | 0.21% | | Dow Jones Industrial Average (DJI) | 52786.07 | -1.18% | | S&P 500 (GSPC) | 7673.52 | -0.58% | | Nasdaq (IXIC) | 26421.41 | -0.32% | | Philadelphia Semiconductor (SOX) | 11887.87 | 1.3% | Although the Dow Jones fell by over 1%, the Philadelphia Semiconductor Index bucked the trend to rise 1.3%. This might bring a glimmer of hope to Taiwan's tech stocks tomorrow, though the overall sentiment of the international market remains conservative and volatile. ## Key Stock AI Predictions This section features individual stocks with actual AI price and direction predictions. | Stock | Direction | Target Range | Confidence | Technical Signals | | --- | --- | --- | --- | --- | | - | - | - | - | - | Today, the AI model is relatively cautious regarding individual stock predictions, and there are currently no stocks meeting our screening threshold. Adhering to our principle of honesty, we never force-feed junk data. Let's jump straight to the performance of our Stock Selection Strategy Radar! ## Stock Selection Strategy Radar *Reminder: The following are the technical and chip-flow screening results from our strategy screener (`screen_stocks`), **intended for quantitative observation only, not as buy/sell predictions for individual stocks**.* | Stock | Overall Score | Chip Score | P/E Ratio | Valuation | | --- | --- | --- | --- | --- | | Mega Financial (2886) | 80 | 100 | , | , | | Hua Nan Financial (2880) | 74 | 100 | , | , | | Taiwan Mobile (3045) | 73 | 100 | 22.31 | cheap | | Taiwan Cooperative Financial (5880) | 73 | 100 | , | , | | Feng Tay (9910) | 73 | 100 | 14.59 | cheap | - **Mega Financial (2886)**: Today's overall score is 2.3, leaning towards "Buy". Technical momentum is strengthening, and a bullish engulfing pattern alongside MACD bullish divergence suggests the decline is stabilizing. However, the Williams %R indicates overbought conditions, so beware of chasing highs. - **Hua Nan Financial (2880)**: Score is 0.8, currently leaning towards "Wait-and-See". Although RSI and price-volume show bullish divergence and volume is quietly stabilizing, there are also short-term overbought signals, making it unwise to excessively chase highs. - **Taiwan Mobile (3045)**: Score is -1.7, leaning towards "Wait-and-See". Although the valuation is cheap and there is a bullish engulfing pattern, note that the Williams %R is overbought and MACD shows bearish divergence, suggesting the upward momentum is starting to fade. - **Taiwan Cooperative Financial (5880)**: Score is 0.8, leaning towards "Wait-and-See". Technical momentum is strengthening with bullish candlestick patterns, but the Williams %R has reached the overbought zone at 0, so caution is advised when chasing highs. - **Feng Tay (9910)**: Score is 0.8, leaning towards "Wait-and-See". The valuation is cheap, and trading volume surged by 2.88 times today, showing a clear return of market interest. However, a bearish "shooting star" candlestick pattern has appeared on the technical side, indicating that bulls and bears are still locked in a tug-of-war. ## Recent Prediction Accuracy Review
