Foreign inflows and earnings upgrades drive Taiwan technology shares higher, but elevated valuations and ETF outflows signal risks

Overview

This report is a weekly Taiwan market tracker. It notes that renewed foreign inflows and strength in the technology sector lifted Taiwan equities, while fundamental data also showed that July revenue and 2Q26 earnings generally exceeded expectations, supporting subsequent earnings forecast upgrades. At the same time, forward market valuations are above historical averages, ETF flows have turned negative, and risk indicators and forthcoming macro data remain worth monitoring.

Core views

Near-term drivers for the Taiwan market are foreign buying and rising technology shares, especially technology hardware and other semiconductors. On earnings, the share of 2Q26 results exceeding expectations was higher than the share missing expectations, and July revenue maintained strong growth, driving upward revisions to 2027 consensus EPS. The MSCI August 2026 rebalance is expected to bring net passive inflows, but ETF outflows and elevated valuations mean the market is not without volatility risks.

Analysis framework

The report conducts a comprehensive weekly assessment of the Taiwan equity market by combining market and sector performance, foreign and local fund flows, ETF flows, MSCI index changes, monthly sales, quarterly earnings, EPS revisions, valuations, style factors, and risk indicators.

Methodology notes

• Index Rebalancing AnalysisMSCI Index Review

  Estimates passive fund flows and sector weight changes based on constituent changes in MSCI Standard and IMI indices.

  In the August 2026 review, Taiwan's Standard Index is expected to add three stocks and remove six; the report estimates the rebalance will generate US$6.2 billion in two-way passive flows and US$1.2 billion in net inflows.

• Earnings TrackingConsensus EPS Revisions

  Tracks changes in bottom-up consensus EPS forecasts across sectors.

  The report shows that consensus 2027 EPS rose 1.9%, with the most pronounced positive revisions in capital goods and technology.

• Valuation AnalysisForward Price-to-Earnings Ratio

  Uses 12-month and 24-month forward P/E ratios and compares them with historical standard deviations.

  Taiwan market 12-month and 24-month forward P/E ratios are 19.3x and 15.1x, respectively, 1.8 and 0.9 standard deviations above historical averages.

• Risk MonitoringTSMC ADR Premium Reversal Index

  Assesses signals of a potential reversal in the TSMC ADR premium through a model-based indicator.

  The TSMC ADR premium remained at 15%, while GSSRTSMR was +0.4; the report interprets this as a potential reversal signal.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• TAIEX

  Taiwan broad equity market benchmark

  Strengths

  Foreign net buying, technology sector leadership, earnings forecast upgrades, and potential MSCI passive inflows.

  Weaknesses

  Forward valuations are above historical averages and ETF flows have weakened.

  Comparison

  Weekly gain was approximately 1.1 percentage points higher than MXAPJ.

  Risks

  Cross-strait risks, policy risks, reversal of foreign flows, and weaker-than-expected macro data.

• Taiwan Technology Hardware and Semiconductors

  Key beneficiary sectors of the current market rally

  Strengths

  Technology hardware rose 8% and other semiconductors gained 6.5%; sales and earnings performance support EPS upgrades.

  Weaknesses

  Following substantial sector gains, valuation pressure and profit-taking risk may emerge.

  Comparison

  Significantly outperformed lagging sectors including utilities, telecoms, metals and mining, and banks.

  Risks

  Slower global technology demand, supply-chain disruptions, and lower market risk appetite.

• Taiwan ETFs

  Reflect local market allocation sentiment

  Strengths

  Broad-market ETFs still recorded approximately US$0.5 billion in inflows.

  Weaknesses

  Overall net outflows totaled US$0.7 billion, the first weekly net outflow in four months.

  Comparison

  Outflows were more pronounced in active, leveraged, and high-dividend ETFs, while broad-market ETFs were relatively more resilient.

  Risks

  Continued retail outflows could amplify market volatility.

Impact & implications

For Taiwan equities, fund inflows and earnings upgrades jointly reinforce relative support for technology and capital goods. MSCI changes could provide a short-term passive-flow catalyst, while technology hardware and semiconductors will also benefit in index weights. However, market valuations are already above historical averages, and ETF outflows and cross-strait risks may still increase volatility; investors should assess strong fundamentals alongside valuation and flow developments.

Risks

• Taiwan market valuations are above historical averages, which may constrain further valuation expansion.
• ETF net outflows and retail selling of equities and ETFs may weaken near-term liquidity conditions.
• Although foreign investors were net buyers of cash equities, their increased futures short positions indicate ongoing hedging demand or near-term caution.
• Changes in cross-strait risk indicators, geopolitical risks, and policy risks could increase market volatility.
• Forthcoming macro data, such as export orders, could affect expectations for technology and export-related sectors if weaker than expected.
• The TSMC ADR premium reversal indicator signals potential reversal risk in the premium.

What to watch

• MSCI index changes taking effect after August 31 and actual passive fund flows.
• Taiwan export orders data.
• Whether foreign net cash-equity buying continues and changes in futures short positions.
• August monthly sales data and delivery of third-quarter revenue.
• EPS revision trends across industries following 2Q26 earnings releases.
• Whether Taiwan ETF flows can shift from net outflows back to net inflows.
• Changes in the TSMC ADR premium, cross-strait risk indicators, and geopolitical risks.
