The concept became particularly visible in Indonesia in January 2026, when the Indonesia Stock Exchange halted trading after the Jakarta Composite Index (IHSG) reached an 8% decline on January 28 and 29.
However, hedging does not mean eliminating investment risk. Instead, it is designed to reduce the potential damage from a particular risk. Investors may use diversification, gold, US dollar-denominated assets, cash, money market funds, stop-loss orders, or derivatives depending on their portfolio and objectives.
What Is Portfolio Hedging?
Portfolio hedging is an investment risk-management strategy designed to reduce the impact of unfavorable price movements.
The basic idea is similar to insurance. Investors accept a certain cost or sacrifice some potential returns in exchange for reducing potential losses when markets move against them.
For example, an investor holding only stocks could see a substantial decline when the broader stock market falls. By allocating part of the portfolio to assets that may behave differently, the overall decline could be smaller.
However, hedging does not guarantee protection. Assets that normally move differently can also fall at the same time.
A portfolio decline of 20%, for example, requires a subsequent 25% gain to return to its original value. This illustrates why managing downside risk can be important for long-term investors.
Why Do Investors Hedge Their Portfolios?
Several risks can encourage investors to consider portfolio hedging.
Market risk occurs when broad market conditions push multiple stocks lower at the same time. Individual stocks can also have different levels of sensitivity to market movements, commonly measured through beta.
Concentration risk appears when too much capital is allocated to one stock, sector, country, or asset class. A single event can have a disproportionately large effect on the portfolio.
Currency risk is another consideration, particularly for Indonesian investors holding foreign assets. Changes in the USD/IDR exchange rate can affect the rupiah value of US dollar-denominated investments.
Inflation risk can also reduce purchasing power when large amounts of money remain in low-yielding assets.
Finally, volatility risk is particularly relevant for assets such as cryptocurrencies, where prices can move significantly within a short period.
6 Ways to Hedge a Portfolio
There is no single hedging method suitable for every investor. The following six strategies range from relatively simple approaches to more complex instruments.
1. Diversify Across Asset Classes
Diversification is one of the simplest ways to reduce concentration risk.
Instead of allocating all capital to Indonesian stocks, investors can spread exposure across different asset classes, such as:
- Indonesian stocks
- US stocks and ETFs
- Gold
- Mutual funds
- Cash or money market funds
- Cryptocurrencies
The purpose is to prevent one asset from determining the performance of the entire portfolio.
However, diversification does not eliminate losses. During periods of severe market stress, several asset classes can decline simultaneously.
2. Add Gold to the Portfolio
Gold is frequently used as a portfolio diversifier because its price does not always move in the same direction as stocks.
The World Gold Council reported that the average LBMA gold price increased 44% in 2025 compared with 2024. Gold also recorded 53 new price records during that year.
Despite this performance, gold should not be considered a guaranteed hedge. Spot gold experienced an intraday decline of as much as 6.3% on October 21, 2025.
For Indonesian investors, digital gold can also provide a relatively accessible way to gain exposure to the precious metal. Gold-backed crypto tokens such as PAXG and XAUT offer another form of gold exposure, although they remain crypto assets and carry additional cryptocurrency-related risks.
3. Hold US Dollar-Denominated Assets
Investors can also use US dollar-denominated assets, including US stocks and ETFs, to diversify their exposure outside Indonesia.
Currency movements can affect the rupiah value of these assets.
If the rupiah weakens against the US dollar while the underlying asset price remains unchanged, the asset's value in rupiah terms can increase.
The opposite can happen when the rupiah strengthens.
Therefore, US dollar exposure can help address currency concentration while simultaneously introducing exposure to US markets and the USD/IDR exchange rate.
4. Keep Cash or Money Market Funds
Cash and money market funds can provide liquidity when markets decline.
Having liquid funds means investors may not need to sell long-term investments during a market correction simply to meet short-term financial needs.
Money market funds can also play a stabilizing role within a broader portfolio.
However, this strategy has a trade-off. Cash may lose purchasing power because of inflation, while money market funds can still carry investment and credit risks. Mutual funds are also not covered by Indonesia's Deposit Insurance Corporation, or LPS, deposit guarantee system.
5. Use Stop-Loss and Trailing Stop Orders
Stop-loss orders can help investors define an exit level for a particular position.
A stop order is generally triggered when the market reaches a specified price. A trailing stop can adjust the trigger level as the asset price moves favorably.
These tools can make risk management more systematic because investors do not necessarily have to monitor prices continuously.
However, execution is not always guaranteed at the exact price selected. During rapid market movements or price gaps, an order can be executed at a price significantly different from the specified trigger.
For US stocks on Pluang, Stop Orders and Stop Limit Orders can be used from US$1.50 per transaction, according to the supplied product information.
6. Use Derivatives for More Advanced Hedging
More experienced investors can use derivatives such as put options and futures contracts.
A protective put involves purchasing an option that provides the right to sell an asset at a predetermined price. If the underlying asset falls below that level, the option may gain value and offset part of the portfolio's decline.
The trade-off is the option premium. If the anticipated decline does not occur, the premium may become a cost without providing an offsetting gain.
Another approach is a short futures position. An investor holding an underlying asset can take a short position in a futures contract to potentially offset some losses if the underlying market falls.
However, derivatives can involve leverage and complex mechanics. Losses can potentially become substantial, making these instruments more appropriate for investors who understand their risks and mechanics.
Portfolio Hedging Example With Rp10 Million
Consider two hypothetical portfolios, each starting with Rp10 million.
Portfolio A puts 100% of its capital into stocks.
Portfolio B allocates:
- 60% to stocks
- 20% to gold
- 20% to money market funds
Suppose stocks decline by 8%, while gold and money market funds remain unchanged.
Portfolio A would lose:
Rp10 million × 8% = Rp800,000
Portfolio B would lose:
Rp6 million × 8% = Rp480,000
In this simplified scenario, Portfolio B experiences a smaller decline.
But the protection also has a cost.
If stocks rise 8% while gold and money market funds remain unchanged, Portfolio A gains Rp800,000, while Portfolio B gains Rp480,000.
The example demonstrates an important principle: hedging can reduce downside exposure, but it can also reduce gains when the protected asset rises.
If gold also falls, the protection becomes smaller.
What Are the Risks and Costs of Hedging?
Investors should consider several factors before implementing a hedging strategy.
Transaction costs can reduce returns, particularly when investors frequently adjust their positions.
Opportunity costs also matter. Capital allocated to defensive assets cannot fully participate in a rising stock market.
Changing correlations can make hedging less effective. Assets that historically moved differently may sometimes decline together.
Over-hedging is another risk. Excessive defensive positioning can prevent a portfolio from achieving its long-term growth objectives.
For derivatives, leverage risk requires additional attention because losses can become significant relative to the capital allocated to the position.
Finally, execution risk affects stop-loss strategies. Fast-moving markets and price gaps can result in execution prices that differ from the intended level.

How to Build a Hedging Strategy
Investors considering portfolio hedging can start with a simple process.
-
Map the portfolio. Identify each asset, sector, country, and currency exposure.
-
Identify the main risks. Determine whether the biggest concern is market declines, currency movements, concentration, liquidity, or individual-position losses.
-
Choose an appropriate hedge. Gold, foreign assets, cash, money market funds, stop orders, and derivatives address different types of risks.
-
Determine the allocation. Calculate how a potential market move could affect the overall portfolio before making a transaction.
-
Set risk limits. Investors can establish predetermined loss limits for positions where appropriate.
-
Review the portfolio regularly. Rebalancing every few months can help restore the intended allocation after significant market movements.
Hedging Is About Risk Management, Not Guaranteed Profits
Portfolio hedging is fundamentally about managing risk rather than guaranteeing returns.
Diversification, gold, US dollar-denominated assets, cash, money market funds, stop-loss orders, and derivatives each have different characteristics. The appropriate approach depends on the risks an investor is trying to manage.
The Rp10 million simulation illustrates the trade-off clearly. A portfolio with defensive assets can experience a smaller loss when stocks decline, but it can also record a smaller gain when stocks rise.
For that reason, investors should consider their investment horizon, liquidity needs, risk tolerance, and portfolio objectives before deciding how much protection to use.
Hedging can be useful as part of a broader risk-management framework, but it cannot completely remove investment risk.
