# AI Stock Chat, September 23, 2026: Market consolidating amid a tug-of-war between bulls and bears

> **TL;DR** — Taiwan's TAIEX forecast for September 24 leans neutral at 47393.67~48206.

## Opening

Hi everyone, I'm Muyan, welcome to today's episode of "AI Stock Chat." Today is Wednesday, September 23rd, and we're looking at the forecast for the next trading day, Thursday, September 24th, for the Taiwan stock market. This time, the AI model's signal leans neutral with not particularly high confidence, suggesting the market is still waiting to see which direction it'll go. Let's dive into the details.

## Today's Market Forecast

<figure class="stock-chart" style="margin:1.25rem 0"><svg role="img" aria-label="TAIEX AI Forecast Range (Next Day / Short Term)" viewBox="0 0 612 130" width="100%" style="height:auto;max-width:612px;min-width:480px;font-family:ui-sans-serif,system-ui,sans-serif;font-size:12px"><line x1="206.0" y1="20" x2="206.0" y2="122" stroke="currentColor" stroke-width="1" stroke-dasharray="3 3" opacity=".45"/><text x="206" y="14" fill="currentColor" text-anchor="middle" opacity=".7">Current: 47800.17</text><text x="48" y="57" fill="currentColor" text-anchor="end" font-weight="600">Next Day</text><line x1="56" y1="53" x2="356" y2="53" stroke="currentColor" stroke-width="1" opacity=".18"/><rect x="148.2" y="44" width="115.7" height="18" rx="4" fill="#f59e0b" fill-opacity=".22" stroke="#f59e0b" stroke-width="1.5"/><text x="366" y="57" fill="currentColor">Neutral · 47393.67~48206.67 · Confidence 57%</text><text x="48" y="103" fill="currentColor" text-anchor="end" font-weight="600">Short Term</text><line x1="56" y1="99" x2="356" y2="99" stroke="currentColor" stroke-width="1" opacity=".18"/><rect x="76.7" y="90" width="258.6" height="18" rx="4" fill="#f59e0b" fill-opacity=".22" stroke="#f59e0b" stroke-width="1.5"/><text x="366" y="103" fill="currentColor">Neutral · 46891.20~48709.14 · Confidence 57%</text></svg><figcaption style="font-size:12px;opacity:.6;margin-top:.25rem">TAIEX AI Forecast Range (Next Day / Short Term)</figcaption></figure>

| Horizon | Current Price | Forecast Direction | Target Range | Confidence |
| --- | --- | --- | --- | --- |
| Next Day (9/24) | 47800.17 | Neutral | 47393.67~48206.67 | 57.0% |
| Short Term (1 Week) | 47800.17 | Neutral | 46891.2~48709.14 | 57.0% |

The model's assessment is that, whether looking at tomorrow or the coming week, the TAIEX is more likely to trade sideways within a range, without a clear direction. It's worth noting that although the index itself has ticked up slightly recently, the number of declining stocks has clearly outnumbered advancing ones, suggesting the calm surface hides underlying weakness. This is one reason the model's confidence sits at only 57% and it has opted for a cautious, neutral call.

## Global Market Snapshot

| Index | Close | Change % |
| --- | --- | --- |
| Taiwan Futures Night Session (TXF) | 48497 | 0.56% |
| Dow Jones Industrial Average (DJI) | 51863.69 | -0.36% |
| S&P 500 (GSPC) | 7764.64 | 0% |
| NASDAQ Composite (IXIC) | 27244.28 | 0.45% |
| Philadelphia Semiconductor Index (SOX) | 12689.82 | 2.06% |

The Taiwan futures night session moved higher, and with the Philadelphia Semiconductor Index up more than 2% and the Nasdaq also closing in the green, that's a fairly positive reference signal for Taiwan's tech stocks. That said, the Dow slipped slightly and the S&P was flat, so overall sentiment in the US market remains mixed, without a consistent direction to reference.

## Strategy Stock Screening Radar
The following are strategy screening results, not individual stock buy/sell forecasts, and do not represent any entry or exit recommendations.

| Stock | Composite Score | Fund Flow Score | P/E Ratio | Valuation |
| --- | --- | --- | --- | --- |
| Taiwan Mobile (3045) | 73 | 100 | 23.25 | Fair |
| Formosa Petrochemical (6505) | 70 | 75 | 15.14 | Cheap |
| Realtek (2379) | 69 | 100 | 27.37 | Expensive |
| SinoPac Financial Holdings (2890) | 69 | 75 | , | , |
| CTBC Financial Holding (2891) | 69 | 100 | 16.65 | Expensive |

These stocks all have solid fund flow scores, but the technical signals are actually mixed between bullish and bearish. For example, Realtek's momentum is strong, yet there are concerns about it being overbought, while both Formosa Petrochemical and SinoPac Financial Holdings have shown a KD death cross signaling weakness after reaching high levels. Investors should keep these details in mind when making their own judgment.

## Recent Prediction Hit Rate Review

<figure class="stock-chart" style="margin:1.25rem 0"><svg role="img" aria-label="Recent Directional Hit Rate (higher is better; includes settled sample count)" viewBox="0 0 488 90" width="100%" style="height:auto;max-width:488px;min-width:480px;font-family:ui-sans-serif,system-ui,sans-serif;font-size:12px"><text x="64" y="35" fill="currentColor" text-anchor="end" font-weight="600">Index · Next Day</text><rect x="72" y="22" width="320" height="18" rx="4" fill="currentColor" opacity=".12"/><rect x="72" y="22" width="80.0" height="18" rx="4" fill="#ef4444"/><text x="402" y="35" fill="currentColor">25% (2/8)</text><text x="64" y="69" fill="currentColor" text-anchor="end" font-weight="600">Index · Short Term</text><rect x="72" y="56" width="320" height="18" rx="4" fill="currentColor" opacity=".12"/><rect x="72" y="56" width="64.0" height="18" rx="4" fill="#ef4444"/><text x="402" y="69" fill="currentColor">20% (1/5)</text></svg><figcaption style="font-size:12px;opacity:.6;margin-top:.25rem">Recent Directional Hit Rate (higher is better; includes settled sample count)</figcaption></figure>

Let's be honest about the recent scorecard: the directional hit rate for next-day index forecasts is only 25%, getting it right just 2 out of 8 times. The one-week short-term hit rate is even lower at 20%, with only 1 correct call out of 5, and the average error has widened to 4.06%. The model's recent performance hasn't been great, which is exactly why we keep reminding everyone that these numbers are for reference only and should never be treated as a guaranteed money-maker.
