I'm Pei-Yu. Today, we're going to talk about the market outlook for the next trading day, Monday, August 24, 2026. Although the Taiwan stock market withstood the pressure on Friday and successfully reclaimed its quarterly moving average, it now faces a pullback in US markets. Coupled with foreign institutional investors holding a massive "nuclear-grade" short position of 82,000 contracts, the Taiwan stock market is bound to see a fierce tug-of-war between bulls and bears on Monday. Everyone should be mentally prepared for intraday volatility. ## Today's Market Forecast

TAIEX AI Forecast Range (Next-Day / Short-Term)
We provide "next-day" and "short-term" forecasts for the Taiwan Capitalization Weighted Stock Index (TAIEX) on Monday, August 24, 2026: | Horizon | Current Price | Forecast Direction | Target Range | Confidence | | --- | --- | --- | --- | --- | | Next-Day (2026-08-24) | 44933.74 | Neutral | 44551.61 ~ 45315.87 | 71.0% | | Short-Term (1 Week) | 44933.74 | Neutral | 44079.28 ~ 45788.20 | 70.0% | The system forecasts a consolidated, range-bound market with a tug-of-war between bulls and bears on Monday, August 24, 2026, with a confidence level of approximately 71%. Although Taiwan's export orders for July grew by a robust 61.9% year-on-year, indicating strong fundamentals, the sharp decline in the Dow Jones Industrial Average and rising oil prices nearing $95 due to Middle East tensions could trigger inflation concerns, capping the market's upside potential. The most critical factor on Monday will be whether the TAIEX can withstand the short-selling pressure from foreign institutional investors and hold the defensive line at 44,719. ## Global Market Overview Below is the current global market status. This section presents data only and does not represent forecast directions: | Index | Close | Change % | | --- | --- | --- | | TAIEX Futures Night Session (TXF) | 44804 | -0.22% | | Dow Jones Industrial Average (DJI) | 52759.21 | -1.32% | | S&P 500 Index (GSPC) | 7641.16 | -0.87% | | Nasdaq Composite (IXIC) | 26067.17 | -1.00% | | Philadelphia Semiconductor Index (SOX) | 11800.02 | 0.53% | ## Key Stock AI Forecasts The AI system has not selected any stocks meeting the forecasting criteria today. | Stock | Direction | Target Range | Confidence | Technical Signal | | --- | --- | --- | --- | --- | | N/A | N/A | N/A | N/A | N/A | ## Strategic Stock Selection Radar Below are the results of our strategic screening, primarily providing institutional flow and technical data for reference. This is **not a buy/sell prediction for individual stocks**: | Stock | Overall Score | Institutional Flow Score | P/E Ratio | Valuation | | --- | --- | --- | --- | --- | | Uni-President (1216) | 70 | 100 | N/A | N/A | | Quanta (2382) | 70 | 100 | N/A | N/A | | Evergreen (2603) | 68 | 100 | 9.75 | Expensive | | Taiwan Cooperative Financial (5880) | 68 | 75 | N/A | N/A | | Chang Hwa Bank (2801) | 67 | 100 | N/A | N/A | **Key Comments on Strategically Screened Stocks:** - **Uni-President (1216)**: The score leans slightly toward a sell. The Williams %R technical indicator currently shows overbought conditions, so investors should be cautious about chasing highs. - **Quanta (2382)**: A bullish "engulfing pattern" has appeared technically, but it also shows short-term overbought signals due to recent gains. Chasing prices aggressively is not recommended. - **Evergreen (2603)**: Trading volume has significantly expanded by 1.8 times, indicating strengthening popularity and momentum. However, due to the large short-term gains, the bias (deviation rate) is high, and investors should guard against a pullback correction. - **Taiwan Cooperative Financial (5880)**: The score leans toward a buy. A bullish hammer pattern has appeared on the K-line, and volume is quietly stabilizing, showing a bottom divergence signal between volume and price that suggests a halt to the decline. - **Chang Hwa Bank (2801)**: Moving averages are currently tangled, showing no clear trend direction. The stock price has broken below the monthly moving average, indicating medium-term weakness and a short-term consolidation phase. ## Recent Forecast Accuracy Review
