As of 01:23 Taipei time on the 10th, the Taiwan Weighted Index on the main market was higher by 966.51 points, or 2.32%, and stood temporarily at 42628.21 points. The figures represent a snapshot of trading at the stated time, rather than a final closing result. The index’s advance provided a strong positive reading for the session, although the broader performance figures show that returns varied considerably across different time horizons.

Over the most recent 1 week, the index’s historical change was -7.25%. Across the most recent 1 month, it was -15.52%, while the 3-month change was -5.8%. The reported 6-month change was +0.14%, and the performance since the start of the year was +43.84%. These figures offer context for the day’s rise: the short-term historical periods listed were negative, the 6-month figure was nearly unchanged but positive, and the year-to-date figure remained substantially positive. Each measure covers a different period, so they should be read as separate windows rather than as directly interchangeable results.

The daily increase and the historical changes together illustrate how a market index can show a notable rebound while still reflecting losses over shorter preceding periods. A single intraday movement does not by itself determine whether a broader trend has changed. The latest level and point gain describe the index at the reported moment; the historical percentages describe performance over specified lookback periods. Both types of information can help frame market conditions, but neither alone explains the causes of price movements or signals what will happen next.

Among the highlighted groups, silicon photonics components led the reported advances, rising +7.22% as a group. Within this category, 旺矽 (MPI Corporation, 旺矽, 6223-TW) gained 9.99%, 光環 (LandMark Optoelectronics, 光環, 3234-TW) rose 9.92%, and 華星光 (Wavetek Microelectronics, 華星光, 4979-TW) advanced 9.9%. The reported stock changes show that all three selected names recorded gains, with 旺矽 posting the largest increase among them at 9.99%.

HDI circuit boards were another leading area, with the concept group up +6.95%. Its highlighted stocks also registered positive changes: 定穎投控 (Dynamic Holding, 定穎投控, 3715-TW) rose 9.68%, 金像電 (Gold Circuit Electronics, 金像電, 2368-TW) gained 9.4%, and 臻鼎-KY (Zhen Ding Technology Holding, 臻鼎-KY, 4958-TW) advanced 7.66%. Among these three, 定穎投控 had the largest reported increase. The group result and individual stock results are distinct measures: a concept-group percentage summarizes the category, while each company’s percentage reflects its own reported share-price movement.

The two highlighted themes therefore contributed different but broadly positive signals within the market snapshot. Silicon photonics components posted a group gain of +7.22%, while HDI circuit boards rose +6.95%. The individual names listed in both groups advanced by figures ranging from 7.66% to 9.99%. These numbers describe the reported movements only; they do not establish that every company within either theme rose, nor do they identify the factors behind the gains. No explanation for the index increase or the sector advances was provided in the source information.

For readers following the market, it is useful to separate the broad index result from the performance of selected themes and stocks. The index’s 2.32% rise captures a market-wide benchmark movement at the stated time. The group figures point to areas of relative strength in the update, while the named stocks provide company-level examples. Meanwhile, the negative 1-week, 1-month, and 3-month historical changes underline that the positive intraday reading occurred against a mixed set of recent-period results. The +0.14% 6-month figure and +43.84% year-to-date performance add further perspective, but each remains tied to its own measurement period.

Because the update is an intraday report, the figures may not represent the market’s final position for the day. A temporary index level can change as trading continues, and individual share movements can also fluctuate. The information is therefore best understood as a time-specific account of the index and selected market themes, rather than as a closing summary, forecast, or explanation of investment value.

The reported advance offers a clear snapshot of strength at the time, particularly among silicon photonics components and HDI circuit board shares. The index’s historical figures, however, remain mixed across the listed periods. As trading continues, subsequent market data will show whether the intraday gains persist and how the index and highlighted groups compare with their recent performance. The figures here should be treated as a time-specific update, with no assumption about later market direction.
