• In the first half of 2022, the Asia business accounted for 68.7% of pre-tax profits, with Europe and North America contributing less than 10% and Latin America less than 5%.
• The pre-tax profit in the third quarter of 2022 was USD 3.147 billion, down 41.75% year-on-year but better than market expectations.
• Adjusted revenue in the third quarter grew 28% to USD 14.3 billion, with net interest income increasing by 29.8% year-on-year and 15.2% quarter-on-quarter.
• As of September 2022, the net interest margin was 1.57%, up 38 and 22 basis points year-on-year and quarter-on-quarter, respectively.
• Major shareholder China Ping An Insurance supports spinning off some businesses, which could help boost the group’s valuation.
• The PayMe payment platform has approximately 2.9 million users, accounting for about 50% of the Hong Kong consumer payment market share.
• The U.S. rate hike cycle continues, with Hong Kong’s prime rate adjusting more slowly, leaving room for significant growth in future net interest margins.
• The IMF expects China’s economic growth rate to rebound to 4.4% in 2023, with HSBC strengthening its Asia (especially mainland China and Hong Kong) development center layout.
• The group expects a dividend payout ratio of 50% for 2023 and 2024, targeting an average tangible book return on equity of at least 12% from 2023.

If you monitor both HSBC ADR and HK stock HSBC Holdings, you will notice price differences due to exchange rates, trading sessions, and market sentiment. Understanding this background will help you correctly convert and compare prices in the two markets.

Sources of Price Differences

Exchange Rate Impact

When converting HSBC ADR and HK stock prices, you must first consider the USD to HKD exchange rate. Exchange rate fluctuations directly affect the conversion results between the two markets. For example, when the USD appreciates, even if the HSBC ADR price remains unchanged in the U.S. market, the converted HKD price will rise. Conversely, when the USD depreciates, the converted HKD price will drop. You should note that exchange rates change daily and may show significant differences in the short term. This volatility can lead to different price results depending on the time of conversion. If you ignore exchange rate changes, you are likely to miscalculate the actual value.

Tip: You can refer to the real-time USD to HKD exchange rate and use the latest data for conversion to reduce errors.

Trading Sessions

You should know that the trading sessions in the U.S. and Hong Kong do not overlap. The trading hours for HSBC ADR on the U.S. market are typically from evening to early morning in Hong Kong, while HK stock HSBC Holdings trades during the day in Hong Kong. This time difference can cause noticeable price disparities between the two markets at certain times. Based on historical data, the price volatility ranges during different trading sessions have the following characteristics:

1. Ultra-short-term trading (a few seconds to a few minutes): volatility within approximately 0.5%.
2. Day trading: volatility ranges from 2% to 4%.
3. Swing trading (several days to several weeks): volatility ranges from 5% to 15%.
4. Long-term investment (several months to several years): volatility ranges from 20% to over 50%.

You will find that when major news or economic data is released in the U.S. market, the HSBC ADR price may reflect it first, with the HK stock price adjusting later when the Hong Kong market opens. This time lag effect can cause temporary price deviations between the two markets.

Liquidity

When buying or selling HSBC Holdings in different markets, you will notice significant differences in liquidity. The trading volume of HSBC ADR on the U.S. market is typically lower than that of HK stocks, which can widen the bid-ask spread and intensify price volatility. According to empirical analysis, market liquidity is influenced by multiple factors, including investor types, order imbalances, price volatility, and information asymmetry. When market noise is high or information is asymmetric, liquidity decreases, making prices prone to significant fluctuations. If you trade during periods of low liquidity, you may face larger price slippage, with the actual transaction price deviating from the theoretical value.

• Institutional investors increase liquidity provision during high price volatility, reducing price anomalies.
• Retail liquidity provision is related to stock turnover rate and market capitalization ratio, with stocks having higher market cap and turnover rates offering better liquidity.

You should choose periods or markets with higher liquidity for trading to reduce price losses due to insufficient liquidity.

Fees and Taxes

When converting HSBC ADR and HK stock prices, you must also consider fees and taxes. Trading HSBC ADR on the U.S. market incurs brokerage commissions, exchange fees, and possible ADR management fees. The Hong Kong market involves brokerage commissions, transaction levies, and trading system usage fees. These costs directly affect your actual buying or selling costs. Based on market experience, fees account for a higher proportion of total costs in short-term trading, potentially eating into most profits. For example, when day trading low-volatility stocks (below 1% fluctuation), transaction costs range from 0.4% to 0.5%, making profits nearly impossible. You should calculate the impact of fees on total returns based on your investment strategy and choose the most suitable market and trading method.

Note: When holding HSBC ADR on the U.S. market, you should also be aware of U.S. withholding tax policies, which may affect dividend income.

If you can comprehensively consider the above factors, you can more accurately understand the sources of price differences between HSBC ADR and HK stock, enabling more informed investment decisions.

• The latest transaction price of HSBC Holdings HK stock on the Hong Kong market (in HKD)

• The conversion ratio between HSBC ADR and HK stock (1 HSBC ADR = 5 HSBC Holdings HK shares)

Tip: You can check exchange rates and stock prices in real-time on mainstream financial websites or mobile apps.

Conversion Formula

To convert the HSBC ADR price into the HK stock price, please use the following formula:
HK Stock Price (HKD) = HSBC ADR Price (USD) × USD/HKD Exchange Rate ÷ 5

If you want to convert the HK stock price into the HSBC ADR price, use this formula:
HSBC ADR Price (USD) = HK Stock Price (HKD) ÷ USD/HKD Exchange Rate × 5

Note: The 1:5 conversion ratio is fixed, while the exchange rate varies; you should use the latest exchange rate data for calculations.

Conversion Steps

You can follow the steps below to convert the HSBC ADR price into the HK stock price:

1. Check the latest transaction price of HSBC ADR on the U.S. market. For example: HSBC ADR price is 40.00 USD.
2. Check the real-time USD to HKD exchange rate. For example: 1 USD = 7.85 HKD.
3. Multiply the HSBC ADR price by the exchange rate: 40.00 × 7.85 = 314.00 HKD.
4. Divide the result by 5 (because 1 HSBC ADR equals 5 HK shares): 314.00 ÷ 5 = 62.80 HKD.
5. Obtain the theoretical HK stock HSBC Holdings price after conversion as 62.80 HKD.

5. Obtain the theoretical HSBC ADR price after conversion as 41.40 USD.

You can use the following table to assist with understanding:

Tip: When performing reverse conversion, use the latest exchange rate and stock price, and consider fees and market liquidity.

As long as you master the above conversion methods, you can flexibly compare the prices of HSBC ADR and HSBC Holdings HK stock, making more informed investment judgments.

Conversion Considerations

Exchange Rate Fluctuations

When converting, you must constantly monitor changes in the USD to HKD exchange rate. Exchange rate fluctuations will directly affect the price you calculate. For example, fund management companies hedge against exchange rate risks of NTD or CNY against USD, conducting currency hedging transactions. These hedging measures can only partially reduce the impact of exchange rate fluctuations on asset values. Converting at different times may result in profits or losses due to exchange rate changes. Even with hedging strategies, you will incur settlement costs, which will affect your actual returns. You should regularly check exchange rates and choose periods with lower volatility for conversion to reduce risks.

Tip: You can set exchange rate alerts and convert when the USD to HKD exchange rate reaches your desired level.

Time Lag Impact

You should be aware of the significant time difference between the Hong Kong and U.S. markets. The U.S. market is typically active from evening to early morning in Hong Kong, during which important economic data, such as non-farm payroll figures, are released, causing significant fluctuations in the USD and other currencies. Since the Hong Kong market is inactive during these periods and has lower liquidity, price reactions are delayed. When analyzing prices, you should consider the volatility and liquidity changes caused by the time lag, avoiding large conversions during inactive market periods.

Taxes and Fees

You cannot ignore taxes and fees during the conversion process. Trading on the U.S. market incurs brokerage commissions, exchange fees, and possible withholding taxes. The Hong Kong market involves brokerage commissions, transaction levies, and more. These costs will directly reduce your actual profits. You should calculate all related expenses in advance and incorporate them into the conversion formula to ensure the final result aligns with reality.

Note: When receiving dividends on the U.S. market, you may face withholding taxes, which will affect your total returns.

Other Common Issues

During the conversion process, you may also encounter technical and managerial challenges. Common issues include:

• Insufficient ETL tool performance, where processing speed decreases or even halts with large data volumes.
• Manual operations are prone to errors, such as improper process configuration or staff turnover, leading to data inaccuracies.
• The increasing demand for real-time data analysis may not be met by traditional batch processing.
• Inconsistent data sources require significant conversion and cleanup when integrating multi-system, multi-format data.
• Risk of data loss during migration, necessitating reconciliation mechanisms to confirm data integrity.

You can mitigate these risks by promoting a data culture, enhancing risk management, and selecting appropriate tools. Before converting, you should conduct multiple tests to ensure data accuracy and set priority processing sequences to minimize losses.

When learning to compare HSBC ADR and HK stock prices, you should emphasize exchange rates, the 1:5 conversion ratio, and fees. You can use tables or calculators to assist with conversions, ensuring accuracy. Frequent market comparisons will help you respond more flexibly to price fluctuations.

Tip: Regularly check the latest exchange rates and transaction costs to enhance your investment judgment.
