Global investing has never been easier. With financial markets becoming increasingly interconnected, investors are looking beyond their home markets to diversify and capitalise on global opportunities. However, traditional cross-border investing often involves navigating complex brokerage accounts, foreign exchange risks, and additional transaction fees.

SDRs offer investors access to foreign-listed stocks while keeping transactions in SGD, enabling portfolio diversification without the need for foreign brokerage accounts or complex cross-border transactions.

Since their launch in May 2023, SDRs have emerged as an attractive option for traders seeking to capitalise on global market opportunities. However, SDR trading comes with unique challenges, particularly currency risk and market maker risk. To navigate these risks effectively, investors must develop a solid understanding of how SDRs work and implement strategies to manage and mitigate potential downside risk.

This article delves into the key risks of SDR trading and provides actionable strategies to help investors enhance their trading efficiency and profitability.


Managing Currency Risk

Understanding the Risk

SDRs are denominated in SGD, but their underlying assets are often priced in foreign currencies such as Thai Baht (THB) or Hong Kong Dollar (HKD). Even if the stock price remains unchanged, fluctuations in forex rates can impact the SDR’s price, leading to unexpected gains or losses.


Strategies for Managing Currency Risk

1. Forex Monitoring

Investors can benefit from tracking SGD/THB and SGD/HKD exchange rates to anticipate potential currency fluctuations. A weakening foreign currency against SGD can impact the SDR’s price even if the stock itself remains stable.

2. Overnight Position Control

Holding large overnight positions in SDRs carries forex-related risks. Traders should assess forex trends and adjust their positions accordingly to mitigate potential losses from overnight currency fluctuations.

By actively monitoring forex movements and adjusting exposure, investors can minimise the impact of currency volatility on SDR trading.


Managing Market Maker Risk

Understanding the Risk

Market makers play a crucial role in providing liquidity for SDRs. However, in less actively traded SDRs, they may widen bid-ask spreads, increasing trading costs for investors looking to enter and exit positions.

Understanding market maker behavior is essential for ensuring efficient trade execution and risk management.


Strategies for Managing Market Maker Risk

1. Using Advanced Order Types

Traders can use Limit-if-Touched and Stop-Limit Orders to execute trades at preferred price levels rather than being affected by sudden bid-ask spread widening.

2. Trading During Peak Liquidity Hour

Market makers adjust spreads based on trading activity. Executing SDR trades during periods of higher liquidity can help investors secure better pricing and smoother trade execution.

3. Monitoring Market Depth

Checking the order book can provide insights into buy and sell orders, ensuring transparency in the market and helping traders avoid illiquid SDRs with erratic spreads.

By implementing these strategies, traders can improve execution quality and mitigate risks associated with market makers.


Conclusion

SDR trading gives investors a convenient way to access foreign stocks while transacting in SGD.

However, successful navigation in this market requires a solid understanding of risks such as currency fluctuations and market maker behavior.

By monitoring forex trends, managing overnight exposure, utilising advanced order types, and trading during peak liquidity hours, investors can enhance their potential profitability while minimising the risks.

For those looking to explore SDR trading further, adopting these best practices can lead to a more informed and strategic approach to navigate the market.
