I'm Mu-Yen. Welcome to today's episode of "AI Stock Chat". Today is Tuesday, September 8, 2026. Today, we're going to talk about the latest predictions made by our AI model for the next trading day, Wednesday, September 9, regarding the Taiwan stock market (TAIEX) and popular individual stocks. The market is currently standing firmly above 47,000 points, but behind this high-level consolidation, there seem to be some unusual undercurrents surging. Make sure to listen closely today! --- ## Today's Market Forecast

TAIEX AI Forecast Range (Next-Day / Short-Term)

Our service currently only forecasts the Taiwan Capitalization Weighted Stock Index (TAIEX), providing insights across two dimensions: "Next-Day" and "Short-Term": | Horizon | Current Price | Forecast Direction | Target Range | Confidence | | --- | --- | --- | --- | --- | | Next-Day (09-09) | 47326.27 | Neutral-Bearish | 46923.8 ~ 47728.74 | 58.0% | | Short-Term (1 Week) | 47326.27 | Neutral | 46426.32 ~ 48226.22 | 58.0% | ### Mu-Yen's Plain-English Market Analysis Although the broader market surged by 775 points, don't let the index fool you! This is a classic "TSMC-driven rally" (拉積盤), where capital is heavily concentrated in ultra-large-cap stocks like TSMC. In reality, more than half of the stocks in the market actually fell today. Many investors are "gaining on the index but losing on the price spread." For tomorrow, Wednesday, September 9, the AI model has issued a "neutral-bearish" consolidation signal. Although the Philadelphia Semiconductor Index (SOX) surged and TSMC ADR performed brilliantly, and the spot market tomorrow is highly likely to open with an upward gap due to a "positive basis" (futures trading higher than spot), please pay close attention: foreign institutional investors' net short positions in futures are nearing a historic 80,000 contracts! In the history of Taiwan stocks, a short position exceeding 30,000 to 40,000 contracts was already a high-alert level. Nearing 80,000 contracts is an extremely rare, astronomical figure. This means the market faces a constant risk of major players dumping shares at a high open to force a lower settlement. As for the short-term trend over the coming week, the market is expected to fluctuate between 46,426 and 48,226 points. While supported by TSMC's August revenue and the Apple launch event, we must also face the upcoming US inflation data. The structural risk of more declining stocks than advancing ones persists, so we recommend staying objective and cautious. --- ## Global Market Status Below is the latest closing status of the TAIEX futures night session and the four major US indices. Please note that this section **only presents current data and does not represent AI forecasts**! | Index | Close | % Change | | --- | --- | --- | | TAIEX Futures Night Session (TXF) | 47329 | -0.28% | | Dow Jones Industrial Average (DJI) | 53414.25 | -0.51% | | S&P 500 Index (GSPC) | 7718.6 | -0.38% | | Nasdaq Composite (IXIC) | 26506.99 | -0.29% | | Philadelphia Semiconductor Index (SOX) | 11735.26 | 3.37% | --- ## Key Stock AI Forecasts This section presents the direction and range forecasts generated by the AI model for individual stocks. | Stock | Direction | Target Range | Confidence | Technical Signals | | --- | --- | --- | --- | --- | | (No stock forecasts today) | - | - | - | - | *Mu-Yen's Note: Today, the AI model is taking a wait-and-see approach on individual stocks, and did not generate any stock forecasts that met our high-confidence threshold. That's okay—we believe in honest reporting and will never force a prediction just to fill space!* --- ## Stock Selection Strategy Radar *Reminder: The following content consists of strategic results filtered by the system based on technicals, institutional flows, and valuations. It does **not** constitute buy/sell predictions for individual stocks.* | Stock | Overall Score | Institutional Flow Score | P/E Ratio | Valuation | | --- | --- | --- | --- | --- | | Hua Nan Financial (2880) | 81 | 100 | 19.2 | Expensive | | Wan Hai (2615) | 74 | 100 | - | - | | TSMC (2330) | 73 | 100 | 28.52 | Expensive | | Novatek (3034) | 73 | 88 | - | - | | Taiwan Cooperative Financial (5880) | 73 | 100 | - | - | ### Strategic Stock Analysis * **Hua Nan Financial (2880)**: Overall score of 81. Bullish factors include a bullish hammer candlestick pattern on the technical chart, strengthening momentum, and signs of the decline stabilizing alongside a bullish volume-price divergence. However, bearish factors include a significant short-term rally, with Williams %R indicating overbought conditions, suggesting caution against chasing highs. * **Wan Hai (2615)**: Overall score of 74. Currently, there are no clear buy or sell signals. Although the short-, medium-, and long-term moving averages show a bullish alignment and the stock price has risen above the monthly moving average, the short-term KD indicator is pointing downward. We recommend a wait-and-see approach for now. * **TSMC (2330)**: Overall score of 73. Bullish factors include the MACD histogram turning positive and the appearance of a bullish candlestick pattern. However, bearish factors include bearish divergence in both MACD and volume-price, indicating that the upward momentum is losing steam and buying interest at higher levels is insufficient. * **Novatek (3034)**: Overall score of 73. Although the short-, medium-, and long-term moving averages are pointing upward, the stock price has broken below the monthly moving average, and the short-term KD indicator is pointing downward. There are no clear buy or sell signals today. * **Taiwan Cooperative Financial (5880)**: Overall score of 73. Bullish factors include a bullish hammer candlestick pattern and strengthening momentum. However, bearish factors include a relatively high short-term gain, with Williams %R entering the overbought zone, meaning investors should guard against the risk of chasing highs. --- ## Recent Forecast Accuracy Review

Recent Directional Accuracy (higher is more accurate; includes settled sample size)

We always prioritize honesty and transparency, showing you both the good and the bad! To be completely honest, our AI forecasting model's recent **directional accuracy for the next-day TAIEX forecast was 0.0%** (0 out of 1 correct direction), with the range hit rate also at 0 out of 1, and an average error of 1.67%. Our previous directional forecast indeed met its Waterloo. This proves once again that the market is constantly changing, and even AI models can get it wrong. We will continue to optimize our model, and we urge everyone to treat these forecast figures as just one of many references—never follow them blindly! --- ## Disclaimer Stock and futures trading involve high leverage and risk.
