Bullish strategy · Beginner
Market outlook Bullish
Buy a call for a defined upfront cost, with upside if the underlying rises above breakeven.
Each row reprices every live leg independently. Entry premiums stay fixed.

Dollar-scaled for each leg's quantity, multiplier, expiry, and IV. Theta is per day; vega and rho are per one percentage-point move.

Strike configurations
Buy a call well below the current stock price to trade at a high delta with less time-value decay.
Key difference: Behaves more like leveraged stock; smaller percentage gains but far less theta and vega risk.
Best for: Traders who want stock-like exposure with less capital tied up.
Buy a call above the current stock price for maximum leverage on a big move.
Key difference: Cheaper premium but requires a larger move to reach breakeven; decays fastest if the stock stalls.
Best for: High-conviction, event-driven bets with a defined small stake.
Common questions
Every option loses extrinsic (time) value each day it holds no intrinsic value, a process called theta decay. A flat stock means the call is only losing value, not gaining it.
A call costs less upfront and caps your loss at the premium, but it expires — if the stock doesn't move enough before expiration, the option can go to zero even if you would have eventually been right on direction.
ITM calls cost more but move closer to dollar-for-dollar with the stock and decay slower. OTM calls are cheaper and offer more leverage, but need a bigger move and lose value faster if the stock stalls.
Many traders take profits at 50–80% of the option's maximum realistic gain rather than holding to expiration, since theta decay accelerates in the final weeks and gives back gains if the stock stalls.
