When choosing a Taiwan stock index, you need to first clarify your investment goals. If you pursue market-average returns and want to maximize risk diversification, exchange-traded funds tracking the “Taiwan Weighted Index” are more suitable for you. Conversely, if you want to concentrate on the largest and most stable leading companies and accept higher concentration for potential returns, the “Taiwan 50 Index” is your better choice.

Key Takeaways

• The Taiwan Weighted Index represents the entire market with dispersed risk, suitable for investors seeking stable returns.
• The Taiwan 50 Index concentrates on 50 leading companies with high return potential but more concentrated risk.
• TSMC holds a large weight in the Taiwan 50 Index; its price fluctuations strongly impact index performance.
• Investors should choose the appropriate index and exchange-traded fund tool based on their risk tolerance and investment goals.
• Fubon Taiwan 50 (006208) and Fubon Corporate Governance (00692) are recommended for Taiwan index investment due to lower fees.

Understanding the Two Major Taiwan Stock Indices: Weighted vs. 50

To make an informed choice, you first need to understand the fundamental differences between these two core Taiwan stock indices. They not only represent different investment philosophies but also directly affect your portfolio’s risk and return characteristics. Let us deeply analyze their differences from three key angles: components, historical performance, and sector composition.

Components: Market Overview vs. Leading Selection

Imagine you want to invest in the entire Taiwan stock market. You have two main ways:

• Taiwan Weighted Index: This is like a “panoramic map” covering all listed companies in Taiwan. It includes nearly a thousand companies, from giant tech firms to traditional industry SMEs. Investing in tools tracking this index means your funds are dispersed across the entire market, capturing the overall pulse of Taiwan’s economy. You are buying “diversity.”
• Taiwan 50 Index: This is more like a “star company selection.” It only picks Taiwan’s 50 largest and most liquid companies. Though only 50 stocks, their combined market cap accounts for nearly 70% of the entire Taiwan stock market. You are buying “concentration” and “leading effect.”

Core Comparison

• Weighted Index: Broad coverage, represents market average, extremely dispersed risk.
• Taiwan 50 Index: Few components, represents market head strength, relatively concentrated risk.

Risk and Return: Long-Term Performance and Efficiency Ratio

Long-term, the strategy of concentrating on leading companies has achieved excellent returns. Representative exchange-traded funds tracking the Taiwan 50 Index (like 0050) have annualized returns exceeding 9% since inception, outperforming the broad market in many periods.

However, behind high returns is risk you need to bear. Here we introduce a key metric: Sharpe Ratio. You can understand it as “risk-adjusted return” – how much excess return you get per unit of risk. Higher ratio means better investment efficiency.

Let us look at 5- to 10-year data performance:

Data sourced from multiple index providers and fund historical data, for reference only.

The table clearly tells you that in recent 5 and 10 years, the Taiwan Weighted Index’s Sharpe ratio overall outperforms the Taiwan 50 Index. This means that although the Taiwan 50 Index may surge more in some years, investors bear greater volatility risk for those returns. Choosing the Weighted Index, your investment efficiency may be higher.

Despite efficiency ratio differences, you must know these two indices move highly consistently, with correlation usually between 0.97 and 0.99. They almost always rise and fall together; the difference is in magnitude.

Sector Weights: Tech Stocks’ Dominant Position

Taiwan’s economic lifeline is the technology industry, vividly reflected in both major Taiwan stock indices. Electronics and semiconductor stocks dominate both indices absolutely.

However, the key difference lies in “national protector” TSMC’s weight.

• In the Taiwan Weighted Index, TSMC’s weight, though highest, usually stays around 23% - 30%. Hundreds of other companies share weight, providing buffer.
• In the Taiwan 50 Index, TSMC’s weight is extremely prominent, often exceeding 40%, sometimes approaching 50%.

Warning: Single Stock Risk Exposure

Choosing the Taiwan 50 Index means nearly half your portfolio performance is tightly tied to one company – TSMC. When TSMC performs strongly, your returns are substantial; conversely, if TSMC faces headwinds, your portfolio suffers greater impact.

In summary, the Taiwan 50 Index is a heavy bet on Taiwan’s leading tech companies, especially TSMC. The Weighted Index, though also tech-heavy, significantly reduces reliance on single companies through broader components.

Investment Decision: Which Index Suits You Better?

After understanding index differences, now turn attention to yourself. Your investment personality, goals, and risk tolerance will determine which Taiwan stock index suits you better. Let us use clear investor profiles to help you find the answer and introduce specific exchange-traded fund tools.

Investor Profile: Steady Diversification Type

If your investment philosophy is “not putting all eggs in one basket,” you may be a steady diversification type investor. Check if the following characteristics match you:

• Investment Preference: You tend toward passive investing, hoping for market-matching returns rather than trying to pick outperformers.
• Core Goal: You focus on long-term growth, emphasizing broad diversification for risk management.
• Investment Mindset: You pursue stability and efficiency, whether newbie or experienced, wanting simple transparent market participation.

For this type, your long-term financial goals usually balance risk and return. You want a robust portfolio controlling losses in downturns and capturing most gains in upturns. History shows that in bear markets like 2008 financial crisis, fully diversified portfolios suffered losses but far less than fully stock portfolios.

Your Best Choice: Broad-market exchange-traded funds tracking the “Taiwan Weighted Index.” These tools let you buy Taiwan stock market’s “overview” at very low cost, achieving maximum risk diversification and steadily sharing Taiwan economic growth fruits.

Investor Profile: Leading Concentration Type

If you are full of confidence in Taiwan’s top companies and believe in “strong get stronger,” you are more like a leading concentration type investor. This type’s profile is:

• Investment Preference: You believe market future is defined by few leading companies and accept higher concentration risk for potential above-average returns.
• Core Goal: Your goal is precise investment in largest, most stable blue-chips, especially globally competitive tech giants.
• Investment Mindset: You have deep market understanding, not satisfied with average returns, and strongly confident in future of leading companies like TSMC.

Choosing this path means accepting higher volatility. When leading stocks surge, your assets grow rapidly; when they face challenges, your portfolio faces greater pressure. This is a high-risk, high-potential-return strategy.

Your Best Choice: Exchange-traded funds tracking the “Taiwan 50 Index.” These tools let you heavily hold Taiwan’s 50 largest companies, tightly binding your investment to market’s most influential forces.
