## Opening

Hi, this is Mu Yan, welcome to "AI Stock Chat." Today is Wednesday, September 16, 2026, and the quantitative model is focused on the next trading day, Thursday, September 17, 2026, with Taiwan's benchmark index outlook leaning bearish at 75% confidence. As always, this episode translates the cold, hard numbers into plain language, and brings you the global market picture along with our stock radar.

## Today's Index Forecast

| Horizon | Current Price | Forecast Direction | Target Range | Confidence |
| --- | --- | --- | --- | --- |
| Next Day | 45511.49 | Bearish | 45212.48~45732.51 | 75.0% |
| Short-Term | 45511.49 | Bearish | 44408.99~45571.81 | 75.0% |

In other words, the model's view on tomorrow (Thursday, September 17) is fairly conservative, and the short-term outlook over the coming week isn't much rosier either. The morning sentiment report also carries a bearish tone: the index closed lower, with only 336 advancing stocks versus 673 declining ones, meaning market breadth has clearly weakened. Combined with the simultaneous slump in U.S. semiconductor stocks, this chill could well carry over into tomorrow's open.

## Global Market Snapshot

| Index | Close | Change % |
| --- | --- | --- |
| Taiwan Futures Night Session (TXF) | 45529 | -0.14% |
| Dow Jones Industrial Average (DJI) | 52093.11 | -0.63% |
| S&P 500 (GSPC) | 7585.73 | -0.45% |
| Nasdaq Composite (IXIC) | 25981.57 | -0.78% |
| Philadelphia Semiconductor Index (SOX) | 11175.55 | 0.4% |

The Taiwan futures night session didn't fall too deeply, but all three major U.S. indices weakened in tandem, with the Nasdaq taking the hardest hit. The Philadelphia Semiconductor Index, on the other hand, bucked the trend and closed higher, one of tonight's few bright spots. It's worth watching whether this semiconductor resilience can carry through into tomorrow's (9/17) open.

## Featured Stock AI Forecasts

There's no individual stock AI forecast list from the service today, so we'll skip this section and move straight to the strategy stock-picking radar.

## Strategy Stock-Picking Radar

The following are strategy screening results, not individual stock buy/sell predictions. Please don't treat these as entry or exit signals.

| Stock | Composite Score | Chip Score | P/E Ratio | Valuation |
| --- | --- | --- | --- | --- |
| Quanta Computer (2382) | 72 | 100 | 14.51 | Cheap |
| Hua Nan Financial Holdings (2880) | 70 | 88 | , | , |
| Chunghwa Telecom (2412) | 68 | 100 | 28.19 | Expensive |
| Novatek (3034) | 67 | 88 | , | , |
| Yuanta Taiwan Value High Dividend (00940) | 65 | 100 | , | , |

Quanta's composite score leans toward a wait-and-see stance today, mainly because its rally is showing a MACD bearish divergence, meaning momentum is struggling to keep up. Hua Nan Financial's chip score looks solid, with strengthening momentum and a bottoming signal, but both RSI and Williams %R have flashed overbought, so chasing the rally here calls for caution. Chunghwa Telecom has a perfect chip score yet a bearish overall reading, mainly because after its rally the KD indicator formed a death cross at elevated levels, and both RSI and Williams %R are overbought. Novatek currently has its moving averages in a bullish alignment and is trading above its monthly line, but there's no clear buy or sell signal today, so it's rated neutral. Yuanta Taiwan Value High Dividend is likewise showing a MACD bearish divergence, with its rally losing some steam.

## Recent Forecast Accuracy 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 56" 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="106.7" height="18" rx="4" fill="#ef4444"/><text x="402" y="35" fill="currentColor">33% (1/3)</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>

Honestly, the index's next-day directional hit rate currently sits at just 33.3%, right one out of three times, and full-range hits are at zero, with an average error of 0.48%. This suggests the model's directional calls haven't been very stable lately, so take it as a reference only and don't rely on this number alone for your trading decisions.
