While hedgers use futures to reduce risk, speculators use them to take on risk in pursuit of profit. The leverage inherent in futures trading makes them attractive for expressing directional views with limited capital.

Directional Speculation

If you believe crude oil prices will rise, you can go long oil futures rather than buying physical oil or oil company stocks. The advantages include:

  • Leverage: Margin requirements are a fraction of notional value
  • Liquidity: Active futures markets have tight bid-ask spreads
  • Short selling: Going short is as easy as going long
  • No storage: No need to handle physical commodities

We can quantify the potential risks and returns of a leveraged directional trade:

In[19]:
Code
# Speculative trade example
crude_entry = 75.00
crude_exit = 82.00
contracts = 2
contract_size = 1000  # barrels
margin_per_contract = 6000

investment = contracts * margin_per_contract
profit = (crude_exit - crude_entry) * contract_size * contracts
return_on_margin = (profit / investment) * 100
underlying_return = ((crude_exit - crude_entry) / crude_entry) * 100

# Downside risk analysis
price_drop = 7.00
downside_loss = price_drop * contract_size * contracts

Speculative Crude Oil Trade
========================================
Entry price:         $75.00
Exit price:          $82.00
Contracts:           2
Margin required:     $12,000
Profit:              $14,000.0
Return on margin:    116.7%
Underlying return:   9.3%
Leverage effect:     12.5x
Loss on $7.0 drop:  $14,000.0

The leverage cuts both ways. A $7 decline in oil prices would produce a loss of $14,000, exceeding the $12,000 margin posted and triggering margin calls.

The leverage effect in futures trading. A $150,000 notional position controlled with $12,000 margin creates 12.5x leverage. While the underlying asset return varies linearly with price changes (blue), the return on margin (red) is amplified by the leverage factor.

Spread Trading

Sophisticated speculators often trade spreads (the difference between two related futures prices) rather than outright positions. Spread trades include:

  • Calendar spreads: Long one expiration month, short another (e.g., long December, short March)
  • Inter-commodity spreads: Long one commodity, short a related one (e.g., long crude oil, short heating oil)
  • Inter-market spreads: The same commodity on different exchanges

Spreads typically have lower margin requirements than outright positions because the two legs partially offset each other's risk.
