Seems it’s not practical for retail investors. Here’s what I learned from ChatGPT
“Yes, in theory, you can make a gain from arbitrage between a London-listed share and its ADR listed on the Nasdaq, but in practice, it’s difficult for retail investors to profit from this due to several key barriers.
⸻
🔁 How Arbitrage Would Work
Let’s say a UK company is listed on the London Stock Exchange (LSE), and its ADR is listed on the Nasdaq.
You notice:
• LSE price: £10/share
• ADR ratio: 1 ADR = 2 ordinary shares
• Implied ADR value: £20 = ~$25 at exchange rate 1 GBP = 1.25 USD
• Actual ADR trading at: $27 on Nasdaq
This suggests a $2/ADR arbitrage opportunity.
⸻
🚧 But Here’s Why It’s Difficult
1. Transaction Costs
• Forex fees (GBP/USD)
• Trading commissions on both exchanges
• ADR conversion and cancellation fees
• Spread between bid and ask prices
2. Timing and Settlement Delays
• London and Nasdaq operate in different time zones.
• Settlement times vary (T+2, etc.), making quick arbitrage hard.
3. Access and Regulations
• Some brokers don’t offer cross-market or ADR conversion services.
• Regulatory issues might apply, depending on domicile and tax treaties.
4. Professional Arbitrageurs
• Institutional investors with algorithmic systems already exploit most inefficiencies instantly, leaving no spread for retail investors.

✅ When It Might Work
You might still capture value if:
• There’s temporary dislocation due to news in one market (e.g., UK holiday but US markets open).
• You’re holding ADRs and can convert to local shares (or vice versa) during such mismatches.
• You’re a sophisticated investor with access to both markets, low fees, and fast execution.
