Today’s Taiwan stock market showed a strong pattern with stocks and currency rising together. The TAIEX opened higher and continued upward, led by heavyweight stocks. However, the intraday trend was not smooth all the way, with benchmark stock TSMC embodying the market’s bull-bear tug-of-war.
TSMC Daily Stock Performance (USD)
Indicator Value Open Price 300.95 Intraday Range 276.87 - 325.03 Previous Close 300.43
Such market performance reflects complex internal and external factors. Deeply exploring these dynamics is key to understanding today’s Taiwan stock market trends.
Global financial markets have recently refocused on the US Federal Reserve (Fed)'s monetary policy moves. The Fed’s dovish signals have become the key spark igniting global stocks, especially Taiwan market trends.
The Fed’s policy stance has shifted noticeably. The Federal Open Market Committee (FOMC) made several important decisions in its recent meeting:
Behind this shift are warning signs from US economic data. For example, the latest ADP data showed an unexpected decrease of 32,000 private sector jobs in November, contrasting sharply with market expectations of an increase. Weak labor data has greatly strengthened market expectations for Fed rate cuts to stimulate the economy.
Market Expectations Rising Currently, the market estimates the probability of a Fed rate cut at this month’s meeting has surged to nearly 90%. This expectation psychology directly impacts USD trends, with the Dollar Index (DXY) once falling below 99, hitting a one-month low and continuing recent months’ downtrend.
The Fed’s dovish expectations injected a strong boost into the stock market. Expectations of lower funding costs first spurred a broad US stock rally. The Dow Jones rose 0.86%, while the S&P 500 and Nasdaq Composite also closed higher, showing investor sentiment turning optimistic.
This optimism quickly transmitted to global markets and became one of the main drivers of Taiwan’s year-end rally.
| Impact Level | Specific Analysis |
|---|---|
| Capital Flows | Weak USD prompts international funds to flow out of dollar assets toward higher-risk emerging market stocks, with Taiwan as a major beneficiary. |
| Corporate Valuation | Lower rates reduce corporate borrowing costs and boost stock relative value, especially for valuation-sensitive tech and growth stocks. |
Overall, the Fed’s policy shift creates an extremely favorable macro environment for Taiwan’s tech-weighted market, igniting investor expectations for year-end window dressing.
Despite the Fed’s dovish stance bringing positives, foreign investor moves added complexity. Foreign investors showed significant net selling in recent periods (like November), drawing attention. However, the data reveals not a full capital exodus, but a precise “stock rotation.”
The core logic of this foreign operation is closely tied to Taiwan’s current “high valuation” environment. When the overall market P/E climbs to historically relative highs, institutions naturally become more cautious and seek more attractive value targets.
According to latest data, Taiwan’s current valuation has entered the expensive zone. Compared to historical data over past years, the current P/E has significantly deviated from averages.
| Period | Average P/E (μ) | Std Dev (σ) | Deviation from Current P/E (19.90) | Valuation |
|---|---|---|---|---|
| Last 1 Year | 17.01 | 0.61 | +4.73 σ | Expensive |
| Last 2 Years | 18.16 | 1.23 | +1.41 σ | Overvalued |
| Last 5 Years | 15.93 | 2.23 | +1.78 σ | Overvalued |
| Last 10 Years | 14.80 | 1.73 | +2.95 σ | Expensive |
| Last 20 Years | 13.95 | 1.60 | +3.72 σ | Expensive |
Valuation Observation Simply put, current prices relative to company profits are “expensive” compared to most past periods. This prompts foreign investors to take some profits and shift funds from over-risen stocks to other more promising groups.
The high valuation environment prompted foreign investors to adjust portfolios, directly causing today’s “sector rotation” phenomenon. The capital flow path is clear:
This major position shift strategy explains why today’s market, though stabilized by heavyweights, saw focus on these Tier-2 groups’ strong performance. Foreign investors aren’t bearish on Taiwan’s outlook but reallocating for efficiency, seeking next growth momentum.

In a market woven with bull-bear factors, heavyweights became the key stabilizing force. These large firms’ price performance directly determines the TAIEX direction and provides important observation points for today’s Taiwan stock trends.
Today’s core was benchmark heavyweights playing a “support” role. Leader TSMC’s trend was highly representative — opening higher but facing selling pressure mid-session, yet ultimately holding ground without major downside. This stability effectively offset some mid/small-cap profit-taking selling.
Beyond semiconductor leaders, other groups’ heavyweights also formed a market safety net.
| Supporting Group | Role Played |
|---|---|
| Financial Stocks | Benefiting from rate cut expectations easing and year-end window dressing, some large financial holdings performed steadily. |
| Traditional Leaders | Some shipping and plastics leaders gained support from stable quotes or improving industry outlook. |
| Large Electronics | Beyond TSMC, some large electronics OEMs also showed relative resilience. |
These heavyweights’ collective stability formed the foundation for today’s Taiwan stock trends opening higher and holding steady. Though not the brightest gainers, they played a confidence-building role.
Heavyweights’ steady performance provided solid bottom support for the index, creating two main impacts.
First, it stabilized overall investor confidence. Without collapse risk, market atmosphere avoids panic, encouraging investors to stay and seek opportunities. This safety net from heavyweights is a key premise for maintaining bull patterns.
Second, it created ideal space for sector rotation.
Index Steady, Stocks Lively Precisely because TSMC and others stabilized the market, funds dared to flow out from overbought AI stocks toward lower-base, new-theme groups. This explains the smooth rotation (e.g., to PCB, silicon photonics), forming a “heavyweights steady, mid/small lively” dual-track trend.
In summary, heavyweights’ support is a key piece in understanding today’s Taiwan stock trends, providing necessary conditions for healthy capital rotation.

Despite some AI concept stocks showing pullbacks after rallies, market confidence in AI’s long-term trend remains firm. Today’s market changes don’t signal an AI end, but a healthy rotation from “story-driven” to “P/E-driven”, from “Tier-1 leaders” to “Tier-2 stars.”
AI industry’s long-term growth potential is the fundamental reason it remains an investment axis. Data forecasts from major research firms clearly depict a high-speed expansion blueprint. Especially in AI servers, market scale is expected to explode.
| Item | 2024 Market Size | 2030 Projected Size | CAGR (2025-2030) |
|---|---|---|---|
| Global AI Server Market | USD 124.81 billion | USD 854.16 billion | 38.7% |
Trend Observation A whopping 38.7% CAGR means AI hardware demand will remain strong for years. This clear industry outlook lets institutions adjust short-term holdings without abandoning AI as a core long-term bet.
AI’s long-term trend unchanged, but capital flows flexibly. When Tier-1 AI server OEMs have high rallies and elevated P/E, funds seek the next relay.
| Company | P/E Ratio |
|---|---|
| Wistron Corporation | 21.99 |
| Quanta Computer Inc. | 16.84 |
This search for new opportunities births “sector rotation” phenomena. Funds shift from high-valuation AI server stocks to new-theme, relatively low-base AI sub-groups. Among them, “silicon photonics” is a recent spotlight.
Silicon photonics solves AI computing bottlenecks in high-speed transmission and power consumption, seen as key to sustaining AI development. Markets hold high hopes, with multiple firms forecasting rapid scale growth.
| Forecasting Firm/Report | Forecast Year | Market Value (USD) | CAGR |
|---|---|---|---|
| Fortune Business Insights | 2032 | 1.583 billion | 25.3% (2025-2032) |
| Grand View Research | 2030 | 0.813 billion | 25.8% (2023-2030) |
| MarketsandMarkets™ | 2030 | 0.965 billion | N/A |
Thus, today’s strong silicon photonics, PCB etc. groups reflect AI-axis capital rotation effects. Investors haven’t abandoned AI but shifted to more explosive chain links.
The TWD’s strong trend is another key force moving today’s Taiwan stock trends. Exchange rate moves not only reflect capital direction but directly impact corporate profits, forming a double-edged sword for the market.
Recent international USD weakness plus sustained foreign inflows drove significant TWD appreciation. Mid-session today, TWD/USD rate reached around 0.0321378, showing strong upward trend.
Hot Money Inflow Signal Strong TWD attracts international hot money seeking exchange and interest differentials. Inflows provide ample momentum for stocks, one of the key fuels pushing the TAIEX higher.
However, this capital tide isn’t cost-free. For export-oriented Taiwan economy, overly strong currency erodes corporate profits.
TWD appreciation’s stock impact shows “capital positive, fundamentals negative” contradiction.
First, from capital side, strong TWD attracts foreign inflows — direct momentum for stocks. This explains today’s “stocks and currency rising together” strength, especially benefiting capital-sensitive financials and assets.
On the other hand, from fundamentals, appreciation brings “exchange losses” pressure to export electronics.
Many large electronics face this. Customers may demand price cuts; firms must manage FX risk harder.
| Company | Currency Impact |
|---|---|
| TSMC | Every 1% TWD appreciation expected to reduce operating margin by 0.4% |
| UMC | Every 1% TWD appreciation expected to reduce gross margin by 0.4% |
| ASE Technology Holding | Every NT$1 TWD appreciation vs USD, gross margin expected to decline ~1.5% |
Thus, investors today feel mixed about trends: happy with capital-driven index gains, worried about strong TWD threatening Q4 electronics reports.
In summary, today’s Taiwan stock trends formed a rotation pattern of heavyweights steady, mid/small lively under “foreign rotation” and “domestic window dressing” dual forces.
Fed dovish expectations are the biggest short-term positive. Though AI is long-term axis, watch risks of rapid sector rotations.
Looking ahead, foreign position moves and TWD rate changes will be two major market watches.
Funds are shifting from high-rally, expensive Tier-1 AI stocks to lower-base Tier-2 groups like silicon photonics. This is healthy “sector rotation,” meaning capital still seeks new AI opportunities rather than bearish on the industry.
TWD strength is a double-edged sword.
Thus, capital positive but fundamentals negative.
Heavyweights play a “stabilize confidence” key role. They hold the TAIEX steady, avoiding panic drops. This creates a stable environment letting funds flow from heavyweights to livelier mid/small themes.
