Quick comparison
How payoff works
Options
You pay a premium upfront for the right to buy (call) or sell (put) at a specific strike price before expiry. Your profit depends on where the stock lands relative to the strike, how much time is left, and changes in implied volatility.- Move the right way fast enough → big gains
- Move the wrong way, or not enough, or too slowly → premium decays to zero
Perps
You open a long or short position at the current price. Your P&L moves linearly with the stock — up 1%, you make 1% × your leverage. Down 1%, you lose 1% × your leverage.- No strike, no expiry, no theta
- Liquidation risk if the trade moves far enough against you
Time decay
Options lose value as they approach expiry — even if the stock doesn’t move. This is called theta decay. Perps have no time decay. The only ongoing cost is the funding rate, which is typically small and can even pay you depending on the direction.Complexity
Pricing an option requires understanding:- Strike price
- Expiry date
- Implied volatility
- The Greeks (delta, gamma, theta, vega)
- The current stock price
When options make more sense
- You want defined max loss (long calls/puts cap your loss at the premium paid)
- You’re trading a specific catalyst (earnings, FDA decision) on a known date
- You want to express a view on volatility itself, not just direction
- You’re running multi-leg strategies (spreads, condors, etc.)
When perps make more sense
- You want a simple directional bet without learning the Greeks
- You want no expiry — hold the trade as long as your thesis is intact
- You want to short easily without borrow fees or share availability issues
- You want leverage you control explicitly, not baked into a premium
