Reducing Portfolio Variance with Hedges
For beginners in crypto trading, holding assets in the Spot market can feel risky due to high volatility. You might own Bitcoin or Ethereum outright, but you worry about a sharp, sudden drop in price. A Futures contract allows you to take a position on the future price of an asset without owning the asset itself. The key takeaway for a beginner is that futures can be used not just for aggressive speculation, but also for defense—reducing the ups and downs (variance) of your existing spot holdings. This guide focuses on simple, practical ways to use futures defensively. Always prioritize Securing Your Trading Account before engaging in futures trading.
Understanding the Goal: Variance Reduction, Not Maximum Profit
When hedging, the primary goal is not to make large profits on the futures side, but to stabilize the overall value of your portfolio during uncertain times. Think of it like insurance.
A hedge involves taking an opposite position to one you already hold. If you own 10 ETH on the spot market (a long position), a simple hedge involves opening a short futures position on 10 ETH.
- If the price of ETH drops, your spot holding loses value, but your short futures position gains value, offsetting the loss.
- If the price of ETH rises, your spot holding gains value, but your short futures position loses value.
This process locks your portfolio value relatively close to its current level, reducing volatility. This is crucial when you are unsure about the short-term direction or when you plan to hold an asset long-term but want protection during a known risk period. You must understand First Steps with Crypto Futures Contracts before attempting this.
Practical Steps for Partial Hedging
For beginners, hedging 100% of your spot holdings can sometimes feel restrictive, as you miss out on potential gains if the market moves favorably. A safer first step is Partial Hedging.
Partial hedging means you only hedge a fraction of your spot exposure. This allows your spot holdings to benefit more from upward moves while still providing some downside protection.
1. Assess Your Spot Holdings: Determine the total value of the asset you wish to protect. Say you hold 5 BTC. 2. Determine Hedge Ratio: Decide what percentage of risk you want to neutralize. A 50% hedge means you only hedge half your exposure. 3. Calculate Futures Size: If you hold 5 BTC and decide on a 50% hedge, you need a short futures position equivalent to 2.5 BTC. 4. Manage Leverage: Futures require margin. Even when hedging, you must practice Managing Leverage Carefully. For simple hedging, beginners should aim for very low leverage (e.g., 1x to 3x) on the futures side, or use only the required margin needed to open the position, avoiding Avoiding Overleverage Mistakes. You must also understand Beginner Guide to Futures Margin. 5. Set Expiration/Exit Plans: A hedge is usually temporary. Decide what conditions will cause you to close the hedge—perhaps a major economic announcement passes, or the price reaches a specific support level. You can review strategies in How to Trade Futures with a Swing Trading Strategy.
Risk Note: Remember that funding fees apply to perpetual Futures contract positions. If you hold a long spot position and a short futures hedge for a long time, you will pay the funding rate if the market is heavily shorted, which erodes your net position value. Always check the Funding Rate Effects on Futures.
Using Technical Indicators for Timing Hedges
While hedging protects against large moves, timing when to initiate or close the hedge can improve your net outcome. Technical analysis provides tools to gauge market sentiment and momentum. However, never rely on a single indicator; look for confluence.
Relative Strength Index (RSI)
The RSI measures the speed and change of price movements. It oscillates between 0 and 100.
- Readings above 70 often suggest an asset is overbought, indicating a potential pullback. If your spot asset looks overbought, it might be a good time to initiate a short hedge, anticipating a temporary drop.
- Readings below 30 suggest an asset is oversold, indicating a potential bounce. If you have a short hedge running, an oversold reading might signal it is time to close the hedge and allow your spot position to benefit from the expected upward move.
RSI effectiveness depends heavily on the underlying trend structure. A strong uptrend can keep RSI high for extended periods. See Mastering Breakout Trading with RSI and Funding Rate Analysis for more context.
Moving Average Convergence Divergence (MACD)
The MACD helps identify momentum shifts. It uses moving averages to show the relationship between two different price points.
- A bearish crossover (MACD line crossing below the signal line) can suggest weakening upward momentum, potentially signaling the time to add a hedge.
- A bullish crossover can signal momentum returning, suggesting it might be time to remove an existing hedge.
Be aware that the MACD can lag price action, meaning the signal might arrive after a significant portion of the move has already occurred. Always use Using MACD for Trend Confirmation alongside other tools.
Bollinger Bands
Bollinger Bands consist of a middle band (usually a 20-period simple moving average) and upper and lower bands that represent standard deviations from that average. They measure volatility.
- When the price touches or pierces the upper band, the asset is relatively expensive compared to its recent average, suggesting a potential temporary reversion to the mean. This might be a trigger to initiate a short hedge.
- When the price touches or pierces the lower band, the asset is relatively cheap, suggesting a potential bounce. This might signal closing a short hedge.
Remember, touching the bands is not a guaranteed reversal signal; it confirms high volatility. Look for confluence with RSI readings.
Risk Management and Position Sizing Examples
When hedging, you must define your risk parameters clearly. This includes setting stop losses on your futures position to prevent catastrophic losses due to unexpected market spikes (known as liquidation). Always review your Setting a Daily Stop Loss Cap.
Consider this simple scenario for a 50% partial hedge:
Parameter | Spot Position | Futures Hedge (Short) |
---|---|---|
Asset Held | 100 Units of Coin X | 50 Units of Coin X (Futures) |
Current Price | $100.00 | $100.00 |
Initial Value | $10,000 | N/A (Margin required) |
Stop Loss Target (Futures) | N/A | $105.00 (To limit loss if price spikes) |
$$
If the price drops to $90:
- Spot Loss: $100 (100 units * $10 drop)
- Futures Gain: $500 (50 units * $10 gain)
- Net Change: +$400 (Ignoring fees/funding)
If the price spikes to $110 (and your futures stop loss triggers at $105):
- Spot Gain: $1,000
- Futures Loss (Up to $105 trigger): $250 (50 units * $5 loss before stop)
- Net Change: +$750 (You protected most of the gain while limiting the hedge cost).
This example illustrates how partial hedging lets you participate in the upside while capping the downside risk.

Trading Psychology Pitfalls During Hedging
Hedging introduces complexity that can tempt traders into poor psychological decisions.
1. Over-hedging: If the market moves against your hedge (i.e., the spot price rises while your short hedge loses money), you might be tempted to close the hedge too early to "save" the futures position, exposing your spot holdings again. Resist this urge if your original reason for hedging remains valid. 2. Revenge Trading: If a hedge triggers a stop loss on the futures side, do not immediately open a new, larger trade to try and recover the loss. This is a classic sign of Coping with Revenge Trading Urges. 3. Ignoring Underlying Strategy: If you are using a long-term Spot Buying Strategy DCA Method, a short-term hedge should not derail your long-term conviction. Ensure your hedge aligns with your overall strategy for the underlying asset.
Remember that partial hedging reduces variance, but it does not eliminate risk entirely. You must still manage your risk on the spot side and be prepared for scenarios where hedging is not appropriate—see When Not to Use a Futures Hedge.
Final Considerations
When trading futures, especially when managing hedges, always use Limit Orders Versus Market Orders to control execution price and minimize slippage. Furthermore, be aware of market structure, as concepts like Contango and Backwardation Concepts can influence the cost of rolling futures contracts if you plan to hold the hedge longer than anticipated. Effective risk management, including setting strict leverage caps and understanding margin requirements, is non-negotiable for sustainable trading.
