US-Iran Peace Deal Triggers Foreign Capital Return; TAIEX Hits New High, Favored by Goldman Sachs

Overview

This week, the Taiwan stock market performed strongly driven by geopolitical利好 and robust capital flows. The interim peace agreement between the US and Iran significantly reduced regional tensions, prompting a substantial return of foreign capital. Despite the Federal Reserve's continued hawkish stance, the Taiwan Weighted Index (TAIEX) rose 5.2% in a single week, hitting a record high of 46,465 points. Goldman Sachs maintains an 'Overweight' rating on the Taiwan stock market and sets a 12-month target price of 51,000 points, implying approximately 10% upside potential. The report focuses on capital flows, valuation levels, earnings revisions, and macro data, pointing out that tech and financial stocks are the main beneficiaries, while also monitoring capital dynamics in high-dividend ETFs.

Core views

Market Performance and Capital Flows: Against the backdrop of eased geopolitical risks, foreign investors (QFII) net bought TWD stocks totaling $3.3 billion in a single week, with main inflows into Information Technology, Commodities, Financials, and Defensive sectors. Meanwhile, foreign investors' net short positions in the futures market increased by $3.2 billion, indicating rising hedging demand. Local funds net bought $500 million, mainly focusing on non-TSMC tech stocks and industrial stocks. Retail investor margin ratios remained stable, but futures long positions increased. The short-selling ratio declined further, showing optimistic market sentiment. Industry and Individual Stock Performance: Chemicals (+12%), Insurance (+10%), and Non-TSMC Semiconductors (+8%) led gains, while Transportation (-4%) and Consumer Staples (-2%) lagged. TSMC shares rose 4%, and its premium over American Depositary Receipts (ADR) rose to 21%. The TSMC ADR Premium Reversal Index (GSSRTSMR) developed by Goldman Sachs read +0.9, suggesting a risk of premium contraction or reversal. The Cross-Strait Risk Index (GSSRCSRI) dropped to 95, a relatively low level, reflecting reduced market concerns about regional conflicts. Valuation and Earnings: Currently, the MSCI Taiwan Index's forward 12-month P/E is 22.5x, and the forward 24-month P/E is 18.6x, which are 3.3 and 2.7 standard deviations above historical means respectively, indicating high valuations. Consensus expectations for 2027 EPS were raised by 0.8%, with the largest upgrades in Financials and IT sectors, while Defensive sectors faced downgrades. May listed company revenues grew 45% year-on-year, better than April's 38%, with cumulative sales from April to May reaching 68% of Q2 consensus expectations. Q1 earnings reports showed a 51% year-on-year growth in EPS across the market, with 48% of companies beating expectations. ETF Capital Dynamics: Non-dividend ETFs saw inflows of $500 million in a single week, while dividend products saw inflows of $300 million. Active ETFs continued to attract significant capital, while some traditional high-dividend ETFs experienced outflows. Foreign ownership in Taiwan's non-active/dividend ETFs remained relatively stable, but participation in active ETFs fluctuated.

Analysis framework

Goldman Sachs employs a combined top-down and bottom-up analysis framework. First, it assesses market risk appetite and capital flows by monitoring geopolitical events (such as the US-Iran agreement) and macro policies (such as the Fed's stance). Second, it uses high-frequency capital flow data (foreign investors, local funds, retail investors, ETFs) to verify market momentum and changes in investor structure. Regarding valuation, it combines historical P/E percentiles and standard deviations to assess the attractiveness of current prices, and introduces proprietary ADR premium reversal indices and Cross-Strait Risk Indices as short-term trading signals. Finally, it tracks monthly revenues and quarterly earnings surprises to verify fundamental support, ensuring that the rally has an earnings basis.

Methodology notes

• Event Gaming and Behavioral Finance

  ADR Premium Reversal Indicator (GSSRTSMR)

  This is a quantitative indicator developed by Goldman Sachs to monitor the premium level between TSMC's ADR and its local Taiwan share price. When the premium is too high, this indicator sends signals of potential reversal or contraction, helping investors judge short-term trading opportunities and risks.

• Event Gaming and Behavioral Finance

  Cross-Strait Risk Index (GSSRCSRI)

  A risk indicator constructed by monitoring news sentiment and the frequency of geopolitical events, used to quantify the impact of cross-strait situations on market sentiment. A decline in the index means lower perceived risk, which helps boost valuations of risk assets.

• Valuation methodsPE/PEG valuation

  Forward P/E and Standard Deviation Analysis

  Compares the current market's forward P/E ratio with the long-term historical mean and calculates the deviation in standard deviations (s.d.). When valuations exceed +2 or +3 standard deviations, they are generally considered overvalued, signaling potential pullback risks.

• Industry/Sector Analysis FrameworkVolume-Price Split

  Monthly Revenue Tracking

  Uses high-frequency monthly revenue data to predict quarterly earnings performance. Comparing current month and cumulative revenues with analyst consensus expectations allows for early identification of industries and companies that may beat or miss expectations.

• Taiwan Weighted Index (TAIEX)

  Direct beneficiary, hit new highs driven by foreign capital return and geopolitical easing

  Strengths

  Strong foreign inflows, advantages in the semiconductor supply chain, temporary easing of geopolitical risks

  Weaknesses

  Valuations at historical highs, uncertainty in Fed policy

  Core heavyweight stock; rising ADR premium reflects strong global demand

  Strengths

  Monopoly position in AI chips, strong pricing power, top choice for foreign investors

  Weaknesses

  Excessively high ADR premium may trigger arbitrage or pullback; large base leads to slower growth

  Comparison

  Outperformed other semiconductor stocks, but with relatively lower volatility

  Risks

  Geopolitical risks, technology iteration risks, customer concentration

• Taiwan Financial Stocks (e.g., Fubon Financial, Cathay Financial)

  Benefiting from foreign capital return and interest rate environment; valuations relatively reasonable

  Strengths

Impact & implications

The research report believes that the temporary easing of geopolitical risks and the substantial return of foreign capital provided strong short-term momentum for the Taiwan stock market, pushing the index to new highs. However, high valuation levels (2-3 standard deviations above historical means) and the Federal Reserve's hawkish stance constitute upward resistance. The rise in TSMC's ADR premium, while reflecting global investors' pursuit of AI and semiconductor leaders, also implies risks of short-term profit-taking. For investors, in the current market environment, Financial and IT sectors, which benefit from foreign capital returns and have relatively reasonable valuations, may be more attractive, while caution is needed regarding the volatility of high-valuation tech stocks. Capital flows in high-dividend ETFs show that while investors pursue growth, they still retain allocation demand for defensive assets.

Risks

• Continued hawkish monetary policy by the Federal Reserve, leading to tightening of global liquidity
• Sudden deterioration of geopolitical risks (such as cross-strait relations), offsetting benefits brought by the peace agreement
• Global semiconductor demand falling short of expectations, affecting Taiwan's exports and corporate profits
• Taiwan stock valuations at historical highs, facing pressure from profit-taking
• Impact of RMB exchange rate fluctuations on Taiwan's export competitiveness

What to watch

• Subsequent implementation of the US-Iran peace agreement and geopolitical developments
• Upcoming interest rate decisions and inflation data from the Federal Reserve
• Continued inflows of foreign capital into Taiwan stocks and their hedging behavior in the futures market
• Changes in TSMC ADR premium and signals from reversal indicators
• Release of Q2 earnings reports for listed companies, especially earnings guidance for semiconductor and tech hardware sectors
