FTSE Taiwan Index Semi-Annual Adjustment: Taiwan 50 Valuation Revised Upward, Tech Hardware Faces Significant Outflows
FTSE Russell announced the quarterly adjustment results for the Taiwan index series. The replacement of constituents in the Taiwan 50 will drive a notable increase in the index’s valuation, expected to trigger approximately $13–14 billion in two-way passive fund flows, with tech hardware and semiconductor sectors facing the greatest outflow pressure.
- Four new constituents have been added to the Taiwan 50 index (e.g., Zhen Ding, BizLink), while four old constituents have been removed (e.g., China Steel, Formosa Plastics).
- Following the adjustment, the forward PE ratio of the Taiwan 50 has risen from 16.9x to 21.7x, with EPS growth remaining at a high level.
- The weight adjustment for the Taiwan Dividend+ index amounts to 23.6%, with an anticipated slight increase in dividend yield.
- Banks, chemicals, telecommunications, and capital goods sectors are expected to attract over $1 billion in passive inflows.
- Tech hardware and semiconductor sectors are projected to experience about $2.4 billion in net passive outflows.
- Historical data indicates that buyers tend to underperform sellers prior to index adjustments, though a rebound may follow the announcement.
Report interpretation
Overview
This report, issued by Goldman Sachs’ strategy team, reviews the quarterly review results for the Taiwan index series announced by FTSE Russell after the market close on June 5, 2026. It details the constituent changes for both the FTSE Taiwan Weighted Index (Taiwan 50) and the FTSE Taiwan High Dividend Index (Taiwan Dividend+), quantifying the impact of these adjustments on valuation metrics for both indices as well as the potential passive capital flows they may trigger. Key findings indicate that this adjustment will significantly elevate the valuation of the Taiwan 50 while prompting large-scale reallocations across industries, particularly placing substantial passive selling pressure on the tech hardware sector.
Core views
This index review involved constituent adjustments for two major indices. For the FTSE Taiwan Weighted Index (Taiwan 50), Zhen Ding (4958), BizLink (3665), Global Unichip (3443), and Nan Ya PCB (8046) were added, replacing China Steel (2002), Formosa Plastics (1301), Hotai Motor (2207), and Caliway Biopharm (6919). This change results in a weight adjustment of approximately 1.4%. For the FTSE Taiwan High Dividend Index (Taiwan Dividend+), Winbond Electronics (2344), Nan Ya Plastics (1303), Nanya Technology (2408), Far Eastone (4904), and Chung-Hsin Electric (1513) were included, substituting Makalot Industrial (1477), Tong Yang Industry (1319), Tung Ho Steel (2006), and Radiant Opto-Electronics (6176). Due to the nature of the high-dividend index, the weight shift resulting from this reweighting is more pronounced, reaching 23.6%. In terms of valuation, the adjusted Taiwan 50 index’s forward 12-month price-to-earnings (P/E) ratio will rise from its current 16.9x to 21.7x, reflecting higher valuation premiums among newly included constituents; its compound annual growth rate in earnings per share (EPS) for 2026–2027 remains robust at 36.2% (previously 36.3%), while the trailing dividend yield stays steady at 1.4%. By contrast, the Taiwan Dividend+ index sees its forward P/E ratio decline from 16.2x to 13.4x, with dividend yield slightly increasing from 3.4% to 3.5%, and EPS growth surging from 17.6% to 29.7%, indicating that newly incorporated high-dividend stocks, though lower in valuation, carry stronger growth expectations. Regarding capital flows, the adjustment is projected to generate a total of $13–14 billion in two-way passive trading activity. Sector-wise, banking (+$1 billion), chemicals (+$760 million), telecommunications (+$590 million), and capital goods (+$460 million) are expected to see the largest net passive inflows. Conversely, the tech hardware and semiconductor sector (Tech Hardware & Semis) is anticipated to face approximately $2.4 billion in net passive outflows—the most affected segment.
Analysis framework
Goldman Sachs employed a typical ‘index-rule-driven’ analytical framework. First, by tracking official announcements from the index provider (FTSE Russell), they precisely identified constituent additions and deletions along with corresponding weight changes. Second, using data sources such as Bloomberg and FactSet, they calculated valuation differentials between old and new constituents (e.g., P/E ratios, EPS growth rates), thereby deriving structural shifts in overall index valuations. Finally, integrating passive fund assets under management (AUM) and sector-specific holding weights, they estimated the buying and selling pressures faced by various industries. At the core of this methodology lies an understanding of the rigid need for passive funds to rebalance according to index rules, enabling predictions about short-term liquidity fluctuations.
Methodology notes
Passive Fund Rebalancing Triggered by Index Constituent Adjustments
When an index company announces changes to its constituents, passive funds tracking that index must complete position adjustments before the effective date. Such mechanical buying and selling activities can lead to short-term capital movements unrelated to fundamentals, representing classic event-driven opportunities or risks.
Impact of Passive Capital Flows on Sector Weights
The report breaks down index adjustments into 'buying volume' and 'selling volume,' corresponding to increases and decreases in sector weights. By calculating potential inflow/outflow amounts, investors can better understand which sectors will receive additional buying support and which will face selling pressure due to index adjustments.
Asset mapping & comparison
Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).
- Zhen Ding (4958), BizLink (3665), Global Unichip (3443), Nan Ya PCB (8046)Included in the Taiwan 50 index, benefiting from passive buying support
- Strengths
- Benefit from incremental capital flows brought by index adjustments, with strong valuation elasticity
- Comparison
- Compared to traditional cyclical stocks like China Steel and Formosa Plastics, these tech manufacturing stocks exhibit greater growth potential and higher valuations
- Risks
- If the broader market corrects, passive buying may not fully offset downward pressure
- China Steel (2002), Formosa Plastics (1301), Hotai Motor (2207), Caliway Biopharm (6919)Removed from the Taiwan 50 index, facing passive selling
- Weaknesses
- Must endure short-term liquidity shocks caused by forced selling by passive funds
- Comparison
- Compared to newly added tech stocks, these traditional industry players have relatively lower valuations but weaker growth prospects
- Risks
- If the removal effect persists, stock prices may remain under prolonged pressure
- Tech Hardware & Semiconductors SectorOverall sector weight declines, facing net passive outflows

Impact & implications
This index adjustment will significantly reshape the short-term liquidity landscape of the Taiwan stock market. On one hand, companies newly included in the Taiwan 50 will enjoy sustained passive buying support, potentially driving up their stock prices—especially those previously less widely covered. On the other hand, tech hardware and semiconductor firms being removed may face concentrated passive selling, creating short-term price pressures. For investors, grasping these ‘irrational’ capital flows driven by index rules is crucial, providing a foundation for event-driven strategies—such as positioning ahead of adjustments to capitalize on potential buying opportunities or monitoring rebounds in mispriced stocks after the changes take effect.
Risks
- Market volatility may intensify before the index adjustment takes effect
- Passive capital flows could exacerbate short-term price deviations for individual stocks
- Changes in macroeconomic conditions might negate the capital flow effects of the index adjustment
What to watch
- The official implementation status of the index adjustment after the market closes on June 18, 2026
- Trading volumes and price trends in the tech hardware and semiconductor sectors before and after the adjustment takes effect
- Outperformance of newly included constituents following the effective date
- Additional capital flow impacts arising from global index linkage (GEIS)
