SSE, SZSE, and HKEX

Core Description

The Shanghai, Shenzhen, and Hong Kong stock exchanges (often called "沪深港三所") are Asia’s most influential equity marketplaces, each with unique functions, regulations, and global roles. Together, they offer diverse access to blue-chip, innovative, and international companies while enabling cross-border capital flows. Strategic use of all three markets can help investors achieve global diversification, manage risks, and capture growth opportunities.

Definition and Background

The Shanghai Stock Exchange (SSE), Shenzhen Stock Exchange (SZSE), and Hong Kong Stock Exchange (HKEX) form the backbone of capital markets in East Asia. SSE and SZSE are based in mainland China and are regulated by the China Securities Regulatory Commission (CSRC), while HKEX operates under the Securities and Futures Commission (SFC) of Hong Kong due to its unique legal environment.

Historical Foundations

• Shanghai Stock Exchange (SSE): Founded in 1990, SSE is mainland China’s largest marketplace, primarily listing large state-owned enterprises and blue-chip firms. Its re-establishment marked an important phase of economic restructuring and restored Shanghai’s status as a financial hub.
• Shenzhen Stock Exchange (SZSE): Also launched in 1990, SZSE serves high-growth startups and technology-driven private companies. Its innovative ChiNext board reflects the tech focus seen at NASDAQ, supporting new economy enterprises.
• Hong Kong Stock Exchange (HKEX): Founded in 1891, HKEX has developed into an international exchange, serving as a gateway for foreign capital into Greater China and for Chinese companies seeking global exposure.

Regional Financial Integration

All three exchanges facilitate equity financing, mergers and acquisitions, and capital allocation. Their integration, enhanced through programs like Stock Connect, advances Asia’s financial interconnection, similar to how European bourses like Euronext unify regionally diverse markets.

Calculation Methods and Applications

Market Indices and Benchmarks

Each exchange features flagship indices:

• SSE Composite Index: Tracks all A-shares and B-shares on the SSE, representing the overall market.
• SZSE Component Index: Highlights the performance of 500 major stocks on SZSE, with the ChiNext Index spotlighting high-growth firms.
• Hang Seng Index: HKEX’s flagship index, containing leading companies from finance, real estate, and various sectors.

Trading and Settlement

• SSE and SZSE use a T+1 settlement system, meaning equities bought today can be sold on the next trading day.
• HKEX applies T+2 settlement, aligning with international practices and enabling more flexible fund use.

Currency and Capital Flows

SSE and SZSE transact in Chinese yuan (RMB), while HKEX trades in Hong Kong dollars (HKD). For multi-market portfolios, conversion rates and capital controls are factored into return calculations.

Application: Cross-border Trading

Stock Connect programs enable investors to trade eligible shares on all three exchanges via designated brokers, such as Longbridge, using their local currency and a unified account. This mechanism is similar to Europe’s T2S settlement system or the Japan-Korea cross-listing agreement, expanding investment scope and liquidity.

Equal Accessibility

Some expect all markets to be equally open. Only HKEX allows direct foreign access, while SSE and SZSE require special programs (such as QFII or Stock Connect).

Identical Settlement and Trading

Settlement cycles (T+1 vs. T+2), order types, and trading halts differ and can affect liquidity and cash flows.

Currency and Tax Uniformity

Tax rates, transaction fees, and even dividend processes vary, potentially impacting net returns.

Corporate Governance Standards

HKEX often has stricter standards and more robust investor protection compared to mainland exchanges, shaping transparency expectations.

Case Study (Virtual, Not Investment Advice)

Sarah, an investor based in Germany, uses Longbridge to allocate her portfolio across the three exchanges. She buys blue-chip industrials from SSE, innovative biotech from SZSE, and international banks listed on HKEX. After currency conversion, she reviews her settlement timelines, with next-day for SSE/SZSE trades and two-day for HKEX. This multi-market strategy enables her to balance growth and stability, similar to strategies used by global asset managers seeking exposure beyond their local market.
