Why Buy an Option?

Understanding option leverage and capital preservation in trading

This is an easy conceptual question on option theory that tests whether you understand the basic risk-return tradeoff between owning a stock outright and purchasing call options. It is foundational to any discussion of derivatives and appears regularly in interviews at trading firms evaluating candidates' grasp of fundamental option mechanics.

The question asks you to reason about what an option buyer gains compared to a stock buyer when both are bullish on an underlying asset. The key is to think through how options structure payoffs differently—how they change the shape of your profit and loss curve, your upside exposure, and your capital at risk. A strong answer identifies the specific structural advantage options offer in this scenario and articulates it clearly.
