Alipay QDII Regular Investment vs. U.S. Stock Broker Buying Naa (National) Index Investment Full Comparison

Many people are unclear about their differences; recently, I looked at the comparison of returns over the same period, and the gap is bigger than expected:
January 12 - May 8, investing the same amount daily:
S&P QDII: 5.5-6%
VOO: 7.58%
Nasdaq QDII: 10%
Q: 15.16%
The same money, the same period, returns differ by 30-50%
Why is the difference so large?
1. Hidden losses of QDII
1⃣ Cash drag
Funds hold 5-15% cash to handle redemptions. In a bull market, this part is completely missed. Morgan's S&P Class A still holds 6.65% cash.
2⃣ Rate difference of 20 times
QDII annual fee: management fee 0.8-1.05% + custody fee 0.15% + subscription fee 1.5% + redemption fee 0.5%
VOO annual fee: 0.03%, nothing more.
3⃣ Exchange rate drag
This year, the USD has depreciated nearly 3% against the RMB, averaging a drag of 1.5%.
Conversely, when the USD appreciates, QDII earns more.
4⃣ Time lag
Net value is announced T+1; no trading on domestic holidays.
When U.S. stocks rise, you have to wait until next week to see it.
5⃣ Purchase restrictions
QDII quotas are approved by the State Administration of Foreign Exchange and are limited in total.
Popular funds often have a limit of 100 yuan/day or even suspend trading. Want to add more, but can't.
6⃣ Slow redemption
Redemption funds arrive in 4-7 working days. If you need money urgently, it's stressful.

2. But QDII also has irreplaceable advantages
✅ Starting from 10 yuan, no minimum investment threshold
✅ Buy directly in RMB, no need to exchange currency
✅ No overseas bank account needed
✅ No US tax declaration involved (W-8BEN)
✅ No CRS information exchange
✅ No worries about bank risk control freezing cards
✅ Legal and compliant, clear regulation
✅ Set up automatic deductions, no need to worry 📷
✅ When USD appreciates, exchange rate amplifies returns

3. Advantages and thresholds of U.S. stock brokers
Advantages:
• Very low fees (VOO 0.03%/year)
• 100% tracking, no cash drag
• Real-time trading, good liquidity
• Unlimited amount, buy as much as you want
• Can buy leveraged ETFs like TQ
• Dividends paid directly to account

Thresholds:
• Need an overseas broker (Futu/Tiger/IB/Charles Schwab)
• Need currency exchange (annual limit of $50k per person)
• Complex deposit process, may trigger risk control
• Involves 30% US dividend withholding tax
• CRS information exchange, assets transparent for tax purposes
• Minimum starting from a few thousand USD

4. How to choose
Small funds / afraid of trouble / just want to relax → Use Alipay QDII, set up automatic deductions, don’t worry about it
Large funds / care about returns / already have overseas accounts → Buy VOO directly
Both are not mutually exclusive → Small amounts for habit-building with QDII, big money for ETF gains
Ultimately, investing in the Nasdaq index via regular investment has already outperformed 99% of people.
The tool you use to buy is just the icing on the cake; the most important thing is: start and then compound.
