Today is Friday, August 28, 2026. The weekend is just around the corner, but we still need to do our homework for the next trading day—Monday, August 31—for the Taiwan stock market. US stocks surged on the back of Nvidia's blowout earnings, but foreign institutional investors are lurking with a terrifying amount of short positions. Should we be excited or stay calm when the market opens on Monday? You definitely don't want to miss today's episode! ## Today's Market Forecast
Current Price 45975.22Next-DayNeutral · 45584.24~46366.20 · Confidence 65%Short-TermNeutral · 45100.96~46849.48 · Confidence 62%
TAIEX AI Prediction Range (Next-Day / Short-Term)
Our service only forecasts the Taiwan Capitalization Weighted Stock Index (TAIEX). Below are the AI model's predictions for next Monday (August 31) and the coming week: | Horizon | Current Price | Predicted Direction | Target Range | Confidence | | --- | --- | --- | --- | --- | | Next-Day (08-31) | 45975.22 | Neutral | 45584.24 ~ 46366.20 | 65.0% | | Short-Term (1 Week) | 45975.22 | Neutral | 45100.96 ~ 46849.48 | 62.0% | Although US stocks and the night session surged, making a higher open on Monday almost certain, our AI model still forecasts a "Neutral" outlook for Monday's market. The primary reason is that foreign institutional investors currently hold a massive short position of over 84,000 futures contracts—a veritable Sword of Damocles hanging over the market! They could dump their holdings at any moment during a high open. Additionally, with key US officials scheduled to speak soon, the market is highly likely to shift into wait-and-see mode after an initial gap up. Therefore, the most critical question for next Monday is: "Can the market hold its gains after opening high, or will it face another round of institutional dumping?" Beginners, please do not impulsively chase the rally at the opening bell! ## Global Market Status Below is the latest closing status of US markets and TAIEX Night Futures (for reference only, no predictions): | Index | Close | Change % | | --- | --- | --- | | TAIEX Night Futures (TXF) | 46388 | +0.7% | | Dow Jones Industrial Average (DJI) | 53569.44 | +0.2% | | S&P 500 Index (GSPC) | 7730.99 | +0.72% | | Nasdaq Composite (IXIC) | 26541.35 | +1.57% | | Philadelphia Semiconductor Index (SOX) | 11882.17 | +2.33% | ## Key Stock AI Predictions (No individual stock predictions today) Mu-Yen wants to clarify that our AI prediction model did not filter out any individual stocks that met our criteria today. Adhering to our principles of honesty and transparency, we never force or fabricate predictions when there are no clear signals. Let's focus on the broader market and our strategic stock selection today! ## Strategic Stock Selection Radar Below are the results of our strategic screening, not buy/sell predictions for individual stocks. | Stock | Overall Score | Institutional Flow Score | P/E Ratio | Valuation | | --- | --- | --- | --- | --- | | ASUS (2357) | 77 | 100 | 14.15 | Fair | | Hotai Motor (2207) | 73 | 100 | 12.96 | Cheap | | TSMC (2330) | 72 | 100 | 27.94 | Expensive | | Uni-President (1216) | 71 | 100 | - | - | | Taiwan Cooperative Financial (5880) | 70 | 100 | 16.37 | Cheap | - **ASUS (2357)**: Today's overall score falls within the wait-and-see range. Although it scored a perfect 100 in institutional flow and a bullish hammer pattern appeared on the technical chart, bulls and bears are still in a tug-of-war. - **Hotai Motor (2207)**: Despite its cheap valuation, the technical indicators show a weakening signal with a KD death cross at high levels, suggesting potential short-term correction pressure. - **TSMC (2330)**: No clear buy or sell signals at the moment. Although the stock price has climbed above the monthly moving average and short-term KD is bullish, the moving averages are tangled, and the valuation remains high. We recommend staying on the sidelines for now. - **Uni-President (1216)**: Although the CCI momentum indicator is turning bullish and strengthening, the Williams %R indicates it has entered overbought territory. The risk of chasing the rally in the short term is high, so exercise caution. - **Taiwan Cooperative Financial (5880)**: No clear signals currently. The stock price has broken below the monthly moving average, showing medium-term weakness. Although the short-term KD is pointing upward, the moving averages are tangled. We suggest waiting for a clearer direction. ## Recent Prediction Accuracy Review
Market · Next-Day0% (0/4)
Recent Directional Accuracy (higher is better; includes settled sample size)
Alright, it's time for our most raw and honest "reality check." I have to be completely upfront with you: our recent next-day market forecasts have been absolutely brutal. **Our directional accuracy is 0.0%** (0 out of 4 correct predictions), the number of times we nailed the exact range is also 0, and our average error stands at 1.46%. The model has clearly been thrown off by the recent whipsaw market conditions, where bulls and bears are constantly battling. We will never sugarcoat the data—a miss is a miss. This also serves as a reminder that AI model predictions are merely probabilistic estimates. The market is highly unpredictable, so please never enter a trade blindly based solely on a forecast! ## Disclaimer This content is automatically generated by an AI model based on quantitative data and is for research reference only.
