Advice on Investing in BYD: Which Ticker to Choose for Ownership vs Minimum Lot Size?

Hi everyone, I'm currently evaluating different options for investing in BYD and would appreciate your thoughts on which ticker to choose, considering both ownership and minimum lot sizes. Here are the details of the options I’m looking at:

1. **Ticker 81211 (Hong Kong Stock Exchange)**:
* Price: 372 CNH/share
* Type: **LTD-H** (Proprietary)
* Minimum lot: 500 shares
* Total cost: around $25,000 (ownership)
2. **Ticker 1211 (Hong Kong Stock Exchange)**:
* Price: 397 HKD/share
* Type: **LTD-H** (Proprietary)
* Minimum lot: 500 shares
* Total cost: around $25,000 (ownership)
3. **Ticker 002594 (Shenzhen Stock Exchange)**:
* Price: 370.83 CNH/share
* Type: **LTD-A** (Proprietary)
* Minimum lot: 100 shares
* Total cost: around $5,000 (ownership)
4. **HYDD (Singapore Stock Exchange)**:
* Price: 6.76 SGD/share
* Type: **LTD-SDR** (Not Proprietary)
* Minimum lot: 100 shares (1:10 share ratio)
* Total cost: low but no ownership
5. **BYDDY (US OTC Market)**:
* Price: 103 USD/share
* Type: **LTD-Unsponsored ADR** (Not Proprietary)
* Minimum lot: 1 share
* Total cost: moderate but no ownership
6. **BYDDF (US OTC Market)**:
* Type: **LTD-H** (Proprietary)
* Note: (NT) = Not available for purchase in Europe i can't buy

Given these choices, I’m curious about your preferences. Do you mind investing in **US contracts with no ownership** (such as ADRs or SDRs), or do you prefer to buy larger lots for **direct ownership** (500 shares or so)? I'd love to hear your thoughts on this! Thanks in advance!
