This passive ETF tracks the MSCI Singapore 25/50 Index and builds its portfolio from Singapore-listed companies with large market capitalizations and high liquidity. It applies the 25/50 rule to prevent concentration in any single stock, which enhances diversification.

It suits investors who want both dividend income and capital gains from a long-term position in Singapore, a market with a stable financial system and high dividend payout ratios.

BlackRock (iShares) launched the ETF in 1996, and it is managed passively (index-tracking).

The fund is characterized by a heavy weighting in banking and real estate investment trusts (REITs), the backbone of Singapore's economy. In particular, the financial sector, which includes the largest banks in Southeast Asia, accounts for more than half of the portfolio, directly reflecting Singapore's characteristically solid financial health and high dividend payouts.

• A leading US-listed ETF specialized in the Singapore market
• Concentrated exposure to the financial and REIT sectors

Assets under management (AUM) stand at $1.1B, and the total expense ratio is 0.50% per year.

Because of its very high weighting in Singapore's large banks, returns are fairly sensitive to the interest rate environment and changes in financial regulation, and stable dividend growth is the key factor determining investment performance.

The fund has held up well even amid volatility in global financial markets, supported by Singapore's stable economic fundamentals. Recently, the weighting of technology companies that benefit from the growth of Southeast Asia's digital economy has been expanding.

Singapore is regarded as a market with strong safe-haven characteristics among emerging markets, so it sometimes serves as a refuge for capital during volatile periods, and steady inflows of global income-seeking capital tend to be observed.

Selective exposure to Singapore blue chips and high dividend income are its strengths, but the high concentration in specific sectors can be a risk factor.

EWC (Canada), EWU (United Kingdom), and EWP (Spain), shown in the table, are single-country ETFs representing developed markets, whereas EWS holds a unique position as the economic center of Southeast Asia. Alternatives among neighboring countries include VNM for Vietnam and EWM for Malaysia. If you want to focus more on technology growth, you could consider individual stocks such as SE (Sea) and GRAB (Grab) as complements to your portfolio.

Before deciding to invest in EWS, review each of the following key country and industry characteristics carefully to see whether they fit your investment strategy.

Singapore has a highly open economic structure, so investors should keep in mind that a global recession or rising protectionism could deliver direct and indirect blows.

In conclusion, it is a core asset suited to investors who prefer low volatility and steady dividend income and want to diversify across blue-chip stocks from Southeast Asia's economic hub.
