Taiwan Stock Exchange Plans Longer Trading Hours, Odd-Lot Reform

Why It Matters

Longer hours and faster odd‑lot processing could attract more domestic and foreign liquidity, enhancing market depth as Taiwan’s tech‑heavy index remains undervalued relative to peers.

Key Takeaways

• Odd‑lot trades may start at 9 a.m., aligning with regular session
• Order‑matching cycle could shrink from five seconds to faster speed
• TWSE aims to extend trading beyond 1:30 p.m., timeline unclear
• Taiex up 50% this year, now world’s fifth‑largest market

Pulse Analysis

Retail investors have long relied on Taiwan’s odd‑lot market to buy fractional shares of semiconductor giants and AI‑driven firms. By moving the start time to 9 a.m. and potentially cutting the five‑second order‑matching window, the TWSE hopes to reduce latency and make small‑ticket trades more attractive. Faster execution not only benefits individual traders but also aligns Taiwan’s infrastructure with global best practices, where sub‑second matching is becoming the norm.

Globally, exchanges are lengthening trading sessions to capture cross‑border flows and accommodate investors in different time zones. South Korea’s market, for example, is expanding to a 12‑hour day. If Taiwan follows suit and pushes beyond its current 9 a.m.–1:30 p.m. schedule, it could see higher participation from overseas funds that trade during U.S. market hours. The extended window would also smooth intraday volatility, giving market makers more time to manage order imbalances as the Taiex continues its 50% rally this year.

Beyond mechanics, the TWSE is leveraging Taiwan’s unique position in the semiconductor supply chain as a strategic narrative. With the index trading at roughly 20 times forward earnings—below the Nasdaq 100’s 25‑times multiple—there is a clear valuation gap that foreign investors can exploit. By urging listed companies to articulate medium‑ and long‑term strategies, the exchange aims to unlock a “supply‑chain premium” that reflects the depth of Taiwan’s manufacturing ecosystem. This dual focus on operational upgrades and narrative building positions Taiwan to sustain its momentum as a leading Asian equity market.
