Frequently Asked Questions (FAQ)

How to choose between Taiwan ETFs 0050 and 006208?

Both track the same Taiwan‑50 index; their top‑10 holdings are nearly identical. The primary difference is total expense: 006208's total management fee has been lower than 0050's over the years (about 0.1%–0.2% lower), giving 006208 a slight long‑term cost advantage via compounding; 0050 offers higher trading volume and liquidity. For small investors doing long‑term regular contributions, prioritize the lower fee ratio.

How does the 30% withholding tax on US dividends affect long-term total return?

Non‑US investors have 30% withheld on dividends. For index ETFs focused on capital appreciation like VOO or VTI (dividend yield ≈ 1.5%), a 30% withholding reduces annualized total return by only about 0.45%; investing in Ireland‑domiciled UCITS ETFs (e.g., VWRA, SWRD) can cut US dividend withholding to 15% and dividends are auto‑reinvested — suitable for high‑net‑worth or tax‑optimizing long‑term investors. ETF ETF

What is the best frequency for regular fixed‑amount investing — monthly, biweekly, or weekly?

Backtests show that shortening DCA frequency from “monthly” to “weekly” affects long‑term annualized returns by less than 0.1%. More critical are fee‑waiver thresholds and deposit discipline. Automatic debits 1–2 days after payroll are the most effective way to avoid human delays and emotional interference.
